In recent years wildfires have entered urban areas, causing breathtaking destruction.
<p>The 2018 <a href="https://www.youtube.com/watch?time_continue=1&v=5KNAl23NwME&feature=emb_logo" target="_blank">Camp Fire</a> in Paradise and <a href="https://www.youtube.com/watch?v=OcyPBHPk_VM" target="_blank">Butte County, California</a> was the deadliest and most destructive fire in California's history. It took 86 lives and destroyed more than <a href="https://www.fire.ca.gov/incidents/2018/11/8/camp-fire/" target="_blank">18,000 structures</a> in a matter of hours.</p><p>Almost two years later, only a fraction of the area's 40,000-plus population has returned. This disaster followed the 2017 <a href="https://www.nbcnews.com/news/us-news/california-wildfire-killed-22-wine-country-was-caused-homeowner-equipment-n962521" target="_blank">Tubbs Fire</a>, which killed 22 people in <a href="https://www.fire.ca.gov/incidents/2017/10/8/tubbs-fire-central-lnu-complex/" target="_blank">California's Sonoma and Napa counties</a>.</p><p>After both fires, drinking water tests revealed a plethora of acutely toxic and carcinogenic pollutants. Water inside homes was not safe to use, or even to treat. Water pipes buried underground and inside of buildings were extensively contaminated.</p><p>We are <a href="https://scholar.google.com/citations?user=dBy5drAAAAAJ&hl=en" target="_blank">environmental</a> <a href="https://scholar.google.ch/citations?user=-LMLQJ0AAAAJ&hl=en" target="_blank">engineers</a> who help communities affected by disasters, and supported responses to both fires. As we conclude in a recently published <a href="https://doi.org/10.1002/aws2.1183" target="_blank">study of burned areas</a>, communities need to upgrade building codes to keep wildfires from causing this kind of widespread contamination of drinking water systems.</p>

Wildfires and Water
<p>Both the Tubbs and Camp fires destroyed fire hydrants, water pipes and meter boxes. Water leaks and ruptured hydrants were common. The Camp Fire inferno spread at a speed of one football field per second, chasing everyone – including water system operators – out of town.</p><p>After the fires passed, testing ultimately revealed widespread hazardous drinking water contamination. Evidence suggests that the toxic chemicals originated from a combination of <a href="https://doi.org/10.1002/aws2.1183" target="_blank">burning vegetation, structures and plastic materials</a>.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzUzNjI0Ni9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTYyNjc3Mjk3MX0.1ge-W2jLk5crLc4babbAJSXVVFjnvjGb0-hBmG4VRIg/img.png?width=980" id="474b2" class="rm-shortcode" data-rm-shortcode-id="50d65b21031efbead0a4327ca6a606c1" data-rm-shortcode-name="rebelmouse-image" />

<p>Firefighting can accelerate the spread of contamination. As emergency workers draw hydrant water, they spread contaminated water through the water pipe network.</p><p>Metal, concrete and plastic pipes can become contaminated. Many plastics take up these chemicals like sponges. As clean water later passes through the pipes, the toxic substances leach out, rendering the water unsafe.</p><p>In the Tubbs and Camp fires, chemicals in the air may have also been sucked into hydrants as water pipes lost pressure. Some water system plastics decomposed and leached chemicals directly into water. Toxic chemicals then spread throughout pipe networks and into buildings.</p><p>Limited water testing by state and local agencies showed benzene and naphthalene were present at levels that could cause immediate harm. These, as well as methylene chloride, styrene, toluene and vinyl chloride <a href="https://doi.org/10.1002/aws2.1183" target="_blank">exceeded longer-term regulated exposure limits</a>. Many of these chemicals cause cancer. All can cause vomiting, diarrhea and nausea after short-term high concentration exposure.</p><p>Anyone who drinks the water containing these substances could be harmed. And simply running a faucet could cause chemicals to enter the air. Hot showers and boiling water would vaporize the chemicals and increase the dose a person breathed in. Some of these substances can also be absorbed through the skin.</p>
Dangerous Contamination Levels
<p>Benzene was found at concentrations of 40,000 parts per billion (ppb) in drinking water after the Tubbs Fire and at more than 2,217 ppb after the Camp Fire. According to the California Office of Environmental Health Hazard Assessment, children exposed to benzene for a single day can suffer <a href="https://engineering.purdue.edu/PlumbingSafety/resources/Benzene-Levels-in-Water.pdf" target="_blank">harm at levels as low as 26 ppb</a>.</p><p>The U.S. Environmental Protection Agency recommends limiting children's short-term acute exposure to <a href="https://www.epa.gov/sites/production/files/2018-03/documents/dwtable2018.pdf" target="_blank">200 ppb</a>, and long-term exposure to less than <a href="https://www.epa.gov/ground-water-and-drinking-water/national-primary-drinking-water-regulations" target="_blank">5 ppb</a>. The EPA regulatory level for what constitutes a hazardous waste is <a href="https://19january2017snapshot.epa.gov/sites/production/files/2015-06/documents/tclp.pdf" target="_blank">500 ppb</a>.</p><p>In early 2019, California conducted contaminated water testing on humans by taking contaminated water from the Paradise Irrigation District and asking persons to smell it. The state found that even when people smelled contaminated water that had less than 200 ppb benzene, <a href="https://engineering.purdue.edu/PlumbingSafety/resources/Dissipatiion-of-Burn-Related-VOC-From-Water.pdf" target="_blank">at least one person reported nausea and throat irritation</a>. The test also showed that water contained a variety of other benzene-like compounds that first responders had not sampled for.</p><p>The officials who carried out this small-scale test did not appear to realize the significance of what they had done, until we asked whether they had had their action approved in advance by an institutional review board. In response, they asserted that such a review was not needed.</p><p>In our view, this episode is telling for two reasons. First, one subject reported an adverse health effect after being exposed to water that contained benzene at a level below the EPA's recommended one-day limit for children. Second, doing this kind of test without proper oversight suggests that officials greatly underestimated the potential for serious contamination of local water supplies and public harm. After the Camp Fire, together with the EPA, we estimated that some plastic pipes needed <a href="https://engineering.purdue.edu/PlumbingSafety/opinions/Final-HDPE-Service-Line-Decontamination-2019-03-18.pdf" target="_blank">more than 280 days</a> of flushing to make them safe again.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzUzNjQ3My9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxNjEyODc2Mn0.R9wOz_c_FbjjzQjHJmkp3YMrlK6lr685c4D0oYmKgqo/img.jpg?width=980" id="e65c6" class="rm-shortcode" data-rm-shortcode-id="f5214fa63e8b9d6db3f0662f304d7445" data-rm-shortcode-name="rebelmouse-image" />
Plastic pipes can be damaged by heat and fire contact. Andrew Whelton / Purdue University
Building Codes Could Make Areas Disaster-Ready
<p>Our research underscores that community building codes are inadequate to prevent wildfire-caused pollution of drinking water and homes.</p><p>Installing one-way valves, called backflow prevention devices, at each water meter can prevent contamination rushing out of the damaged building from flowing into the larger buried pipe network.</p><p>Adopting codes that required builders to install fire-resistant meter boxes and place them farther from vegetation would help prevent infrastructure from burning so readily in wildfires. Concrete meter boxes and water meters with minimal plastic components would be less likely to ignite. Some plastics may be practically impossible to make safe again, since all types are susceptible to fire and heat.</p><p>Water main shutoff valves and water sampling taps should exist at every water meter box. Sample taps can help responders quickly determine water safety.</p><span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="9540d7e271306ed417112042a3efc9a4"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/GnlrzI1wdAI?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
The Smell Test Doesn’t Work
<p>Under no circumstance should people be told to <a href="https://www.waterboards.ca.gov/press_room/press_releases/2018/pr122418_voc.pdf" target="_blank">smell the water</a> to determine its safety, as was recommended for months after the Camp Fire. Many chemicals have no odor when they are harmful. Only testing can determine safety.</p><p>Ordering people to boil their water will not make it safe if it contains toxic chemicals that enter the air. Boiling just transmits those substances into the air faster. "Do not use" orders can keep people safe until agencies can test the water. Before such advisories are lifted or modified, regulators should be required to carry out a full chemical screen of the water systems. Yet, <a href="https://doi.org/10.1002/aws2.1183" target="_blank">disaster</a> after <a href="https://pubs.rsc.org/en/content/articlehtml/2017/ew/c5ew00294j" target="_blank">disaster</a>, government agencies have failed to take this step.</p><p>Buildings should be tested to find contamination. <a href="https://www.purdue.edu/newsroom/releases/2020/Q1/study-your-homes-water-quality-could-vary-by-the-room-and-the-season.html" target="_blank">Home drinking water quality can differ from room to room</a>, so reliable testing should sample both cold and hot water at many locations within each building.</p><p>While infrastructure is being repaired, survivors need a safe water supply. Water treatment devices sold for home use, such as refrigerator and faucet water filters, are not approved for extremely contaminated water, although product sales representatives and government officials may <a href="https://undark.org/2019/09/19/camp-fire-california-drinking-water-carcinogens/" target="_blank">mistakenly think</a> the devices can be used for that purpose.</p><p>To avoid this kind of confusion, external technical experts should be called in assist local public health departments, which can quickly become overwhelmed after disasters.</p><div id="71cf9" class="rm-shortcode" data-rm-shortcode-id="e059d199e8368d282a31601e372e4dda"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1204068265980547075" data-partner="rebelmouse"><div style="margin:1em 0">The Los Angeles City Council's Planning and Land Use Committee signed off on an effort to expand the city's fire-re… https://t.co/fP8Z8mUq7R</div> — IntlCodeCouncil (@IntlCodeCouncil)<a href="https://twitter.com/IntlCodeCouncil/statuses/1204068265980547075">1575907219.0</a></blockquote></div>
Preparing for Future Fires
<p>The damage that the Tubbs and Camp fires caused to local water systems was preventable. We believe that urban and rural communities, as well as state legislatures, should establish codes and lists of authorized construction materials for high-risk areas. They also should establish rapid methods to assess health, prepare for water testing and decontamination, and set aside emergency water supplies.</p><p>Wildfires are coming to urban areas. Protecting drinking water systems, buried underground or in buildings, is one thing communities can do to prepare for that reality.</p>From Your Site Articles

The immediate emergency of COVID-19 has been a powerful reminder that the most valuable things in our lives are our families, friends, and the welfare of our communities.
<p>The current pandemic is a threat to those closest to us today in a way that presages what we will experience on an accelerating basis due to the climate emergency. In a place like California's San Joaquin Valley (SJV), Latinos account for <a href="https://www.latimes.com/california/story/2020-07-25/coronavirus-covid-19-farm-workers-san-joaquin-valley" target="_blank">70 percent</a> of COVID-19 cases, even though they represent 42 percent of the population. Improving access to clean and affordable water even as the pandemic grows more urgent, is critical to reducing the types of burdens worsened by the COVID-19 crisis. Continuing the hard work on groundwater sustainability required by the Sustainable Groundwater Management Act (SGMA) could lessen the impact of future crises in the valley. The low level of preparation communities have experienced around the pandemic, echos what these same communities face for water management on a daily basis and will face with future climate change threats unless fundamental changes are made locally.</p>
Thousands of People in the SJV Live Without Reliable Access to Water.
<p>California is the wealthiest state in the most prosperous country in the world, and yet, there are close to one million people living without reliable access to safe, clean, and affordable drinking water. Most of these people are <a href="https://www.nytimes.com/2019/05/21/us/california-central-valley-tainted-water.html" target="_blank">concentrated in disadvantaged communities</a> in the SJV. California identifies <a href="https://oehha.ca.gov/calenviroscreen/sb535" target="_blank">disadvantaged communities</a> as areas that experience disproportionate levels of a combination of poverty, air and water pollution, high unemployment, and high rates of cardiovascular diseases and asthma. According to a report from the UC Davis Center for Regional Change, residents in these communities are <a href="https://regionalchange.ucdavis.edu/publication/water-justice" target="_blank">over 60% Hispanic</a>.</p><p><span></span>The SJV is one of the most productive agricultural regions in the world, <a href="https://www.ppic.org/wp-content/uploads/water-and-the-future-of-the-san-joaquin-valley-overview.pdf" target="_blank">producing more than half of California's agricultural output</a> with over 200 different crops and annual revenue of about 20 billion US dollars. The astonishing volume of water that agriculture requires has led to over-exploitation of groundwater and the continuous lowering of groundwater levels that has impacted water quality and quantity.</p><p>Groundwater is the primary source for household water needs and agricultural water supply. Yet, thousands of people are unable to drink and use the water in the SJV, because there are multiple contaminants in it. Some of the water pollution comes from natural sources and includes substances like arsenic, but most of it has emerged due to agricultural practices. These contaminants include pesticides and nitrates, which are linked to cancer, birth defects, and blue baby syndrome.</p><p>In years with average precipitation, water flowing in California's rivers from rain and melted snowpack meets about 60 percent of the state's water demand and groundwater meets the remainder. However, during dry years water supply sources shift and put severe stress on groundwater levels. During the California drought from 2012 to 2016, groundwater use, mostly from agricultural water pumping, <a href="https://www.sciencemag.org/news/2020/04/droughts-exposed-california-s-thirst-groundwater-now-state-hopes-refill-its-aquifers" target="_blank">grew to 80 percent</a> in some regions of the SJV increasing overdraft. Groundwater overdraft occurs when water extractions exceed recharge into an aquifer. An analogy is your bank account; extract more money than is put in, and your account will go dry. Aquifers are like a shared account, with some people taking out more than others. Consequently, thousands of domestic wells ran dry, unable to reach water due to lowered groundwater levels, in large part due to increased agricultural water pumping, and affecting thousands of people across the valley.</p><p>We think about drought as standalone events, but in reality, human actions triggered by droughts can have effects that continue long after the drought has ended, like permanently lowering the water table. In the SJV, the last drought has permanently reduced the capacity of some aquifers because overdraft left air in between soil particles instead of water, and the soils subsided eliminating the space for water storage. Overdraft also leads to infrastructure damage from land subsidence, that is when the ground levels drop, plus reduction of surface water, and an increase in water quality problems. That range of concerns brought by overdraft formed the basis of SGMA.</p>Groundwater Sustainability Plans Could Fix Part of the Problem but Are Currently Inadequate.
<p>SGMA passed in 2014 and is the first legislation in California to mandate sustainable management of groundwater resources. SGMA is intended to bring about groundwater sustainability by the year 2040. Local water agencies describe the means to achieve this goal in their Groundwater Sustainability Plans (GSPs). For those interested in the details of SGMA, <a href="https://water.ca.gov/Programs/Groundwater-Management/SGMA-Groundwater-Management" target="_blank">here is a thorough description of it</a>. The focus of this post is on the latest developments.</p><p>The 21 most critically over-drafted groundwater basins submitted their GSPs at the beginning of the year and are now under review by the California Department of Water Resources (DWR). External reviews of these plans argue that some of them do not sufficiently address current and future impacts on disadvantaged communities. For example, the Groundwater Leadership Forum (a group of organizations funded by the <a href="https://waterfdn.org/" target="_blank">Water Foundation</a> focused on ensuring the success of SGMA and of which UCS is part) also reviewed several GPSs and found gaps in how drinking water, climate change, stakeholder involvement, managed wetlands, and groundwater-dependent ecosystems were addressed in the plans. The Public Policy Institute of California (PPIC) reviewed 36 plans submitted for basins overlapping the SJV. They found Kings Basin (surrounding Fresno) stands out for having the highest number of domestic wells that may go dry, about 600 of them, under the proposed water level sustainable thresholds and yet the local groundwater plan considers that an <a href="https://www.ppic.org/blog/will-groundwater-sustainability-plans-end-the-problem-of-dry-drinking-water-wells/" target="_blank">insignificant impact from continued overdraft</a>. This is concerning and unacceptable. Public comments can be consulted in the <a href="https://sgma.water.ca.gov/portal/gsp/all" target="_blank">SGMA portal from DWR</a>.</p><p>I, and many others are concerned that multiple GSPs have questionable integrations of climate change projections. GSPs are considering numerous projects to tackle their local overdraft, yet they are not planning for the uncertain future that climate change is bringing. To reduce some of the vulnerabilities that we see now, GSPs need to integrate climate change and show benefits on the range of future scenarios.</p><p>Another concern is that on May 14, the <a href="http://www.ebudget.ca.gov/FullBudgetSummary.pdf" target="_blank">Governor announced</a> a $40 million cut on funding for SGMA. Part of the money was expected to support 37 new staff positions at DWR to uphold its statutory obligation on reviewing GSPs. While the budget still allocated $26 million of existing Proposition 68 bond funds to help with implementation projects in critically overdraft basin, it is unlikely that DWR will have the capacity to review the GSPs thoroughly. However, the governor's budget did prioritize safe and affordable drinking water and the State Water Board approved <a href="http://californiawaternewsdaily.com/infrastructure/state-water-board-approves-2020-21-funds-to-improve-access-to-healthy-drinking-water/" target="_blank">$130 million for 2020-2021</a> to projects that support such objective on vulnerable communities.</p>Without Bold Action and Preparation, Climate Change Threats May Bring Similar Impacts to Those of COVID-19.
<p>The lack of drinking water causes many residents in the valley to rely on bottled water as their primary source for drinking and cooking. Panic buying at the beginning of the pandemic left stores across the valley without bottled water. In the case of COVID-19, unsafe and unreliable access to water has endangered a multitude of low-income communities by preventing them from performing protective, hygienic acts, handwashing, in particular, and forcing them to go to public water supply kiosks. As we've all learned, hand washing is one of the most necessary measures needed to slow and stop the spread of a virus. Without a correct implementation of groundwater sustainability plans under SGMA, many of these risks will continue.</p><p>Shelter in place orders resulted in people losing their jobs and hence, their source of income and being unable to pay utility services. Small utility services were also impacted because of low economic margins of operations in which small drops in income translate to being unable to provide service. Fortunately, many organizations and individuals wrote a letter to Governor Newsom that prompted him to issue an <a href="https://www.gov.ca.gov/2020/04/02/governor-newsom-issues-executive-order-protecting-homes-small-businesses-from-water-shutoffs/" target="_blank">executive order</a> protecting homes and small businesses from water shutoffs.</p><p>We now have the opportunity to give meaning to these current hardships by learning from them to prevent hardships from climate change. Climate change is a threat intensifier. In this case, the threat is a virus, and historical inequities and water vulnerabilities increased its impact on the most vulnerable among us. An example of the unpreparedness of the system to support our vulnerabilities during times of crisis is seen in the case of school children who rely on school lunches as their main meal of the day but are now unable to access this resource due to school closures. Some farmworkers, <a href="https://www.nytimes.com/2020/04/02/us/coronavirus-undocumented-immigrant-farmworkers-agriculture.html" target="_blank">while cataloged as 'essential' by the federal government</a> during this crisis, are undocumented and were not part of the stimulus package. The height of irony is <a href="https://www.kvpr.org/post/covid-19-deepens-food-insecurity-san-joaquin-valley" target="_blank">farmworkers struggled with access to food distribution</a> when they needed it.</p>There Is No Scenario Where Water Is Not Absolutely Necessary to Lessen the Impacts During a Crisis.
<p>One of my <a href="https://blog.ucsusa.org/cecilia-moura/covid-19-air-pollution-and-health-impacts-an-interview-with-pediatric-pulmonologist-dr-denise-serebrisky" target="_blank">colleagues wrote</a> that moments of crisis often expose the weak points of a system. In the SJV, the weak points of the water system have been exposed for years and won't be strengthened without managing water resources sustainably. This is evidenced by the number of people in the SJV without access to safe, clean, and affordable drinking water. Considering that about <a href="https://www.theguardian.com/environment/2020/feb/28/california-water-wells-dry-sgma" target="_blank">95% of valley residents</a> depend on groundwater for at least part of their water, it is critical that GSPs explicitly include strategies for addressing some of the current and future water issues in the SJV.</p><p>Numerous, various kinds of climate threats will come, whether they develop as <a href="https://www.nature.com/articles/s41558-020-0804-2" target="_blank">floods, heatwaves, wildfires, droughts, or other climate hazards</a>, we need to be prepared and do everything possible to improve sustainable water management for all. While future climate-change-derived crises most likely will be different than COVID-19, there is no scenario where water is not absolutely necessary to lessen the impacts.</p>

Trump Admin Reverses Obama-Era Restrictions on Pebble Mine Near Alaska's Largest Salmon Nursery
27 July
Politics

Officials from the Trump administration announced last week that a plan to open a copper and gold mine that threatens Alaska's largest salmon nursery would not pose a serious environmental threat.
<p>This is a sharp about-face for the U.S. government, after <a href="https://www.ecowatch.com/epa-alaska-mining-salmon-2646141959.html" target="_self">the Obama-administration cited environmental concerns</a> and the threat to the spawning ground of the region's prized sockeye salmon when it put the brakes on the project in 2012, and again when the U.S. Environmental Protection Agency (<a href="http://www.ecowatch.com/tag/epa">EPA</a>) expressed concerns about the salmon in 2014.</p><p>This new move represents the latest salvo in the Trump administration's thorough and systematic dismantling of environmental efforts and regulations from the previous administration. When it comes to the Pebble Mine, as <a href="https://www.washingtonpost.com/climate-environment/2020/07/24/pebble-mine-alaska-trump/" target="_blank">The Washington Post</a> reported, a <a href="https://pebbleprojecteis.com/documents/finaleis" target="_blank">final environmental analysis</a> issued Friday by the U.S. Army Corps of Engineers found that the mine — which targets a deposit of gold, copper and other minerals worth up to $500 billion — "would not be expected to have a measurable effect on fish numbers" in the Bristol Bay watershed, which supports the world's largest sockeye salmon fishery.</p><p>Opponents of Pebble Mine criticized the review process as rushed, flawed, and favorable to the mine developer, as the <a href="https://www.adn.com/business-economy/2020/07/23/as-a-major-federal-environmental-review-comes-to-a-close-six-things-to-know-about-the-pebble-mine-proposal/" target="_blank">Anchorage Daily News</a> reported.</p>
<p>In a joint statement, Alannah Hurley with United Tribes of Bristol Bay, Norm Van Vactor with Bristol Bay Economic Development Corp., Ralph Andersen with Bristol Bay Native Association and Katherine Carscallen with Commercial Fishermen for Bristol Bay said the final review "completely fails to adequately assess the impacts of Pebble on Bristol Bay's waters, salmon, and people," according to the Anchorage Daily News.</p><p>The mine will be located in two watersheds that feed fish-spawning rivers. Opponents say traces of heavy metals and other contaminants left from the mining operation pose risks if they leach into groundwater or if dams holding back the tailings fail in an earthquake, as <a href="https://www.nytimes.com/2020/07/24/climate/pebble-mine-alaska-environment.html" target="_blank">The New York Times</a> reported.</p>
<p>Opposition to the mine has been widespread, both in the region and statewide, for nearly two decades, with concerns about environmental damage and the potential harm to the area's salmon, which are the main traditional subsistence food for many of the Native Alaskans in the region and the crux of both sport-fishing and commercial fishing in the area, according to The New York Times.</p><p>The open-pit mine calls for a large dammed area to trap the tailings from mining operations that would be toxic to the fish. It also calls for the 80 new miles of road to carry the concentrated tailings away to Cook Inlet. Additionally, the mining company wants to build a 165-mile natural gas pipeline for a generating plant to power the operation.</p>
<p>According to the Corps, the operations would permanently destroy more than 2,200 acres of wetlands and waters, and 105 miles of streams. The EPA indicated earlier this year that it would not block the project at this point, as The Washington Post reported.</p><p>Opponents have argued that the environmental impact statement was not rigorous enough, as they highlighted hazardous risks, including the potential for a tailings dam failure that could contaminate waterways used by spawning fish and harm the Bristol Bay fishery, which employs about 15,000 people. They also note that Alaska is the most seismically active state in the nation, and critics said the Corps had not taken sufficient account of the risk of earthquakes or volcanic activity, and that its analysis of the dam designs was inadequate, particularly since a few of the dams would be hundreds of feet high, as The New York Times reported.</p>
<p>Taryn Kiekow Heimer, who leads the the Natural Resources Defense Council's effort to stop the project, told The Washington Post that the administration's push to greenlight a massive project that is opposed by neighboring <a href="https://www.ecowatch.com/tag/indigenous-peoples">Indigenous</a> communities amounts to environmental injustice.</p><p>"It's especially embarrassing for the government and appalling given the current social context we are in," she said of the accelerated approval process. "It's just another example of the entrenched and systemic racism that this government is showing to people of color and indigenous people in particular."</p><p>The Pebble Mine, like logging in Alaska' <a href="https://www.ecowatch.com/amazon-wildfires-trump-alaska-exploitation-2640082295.html" target="_self">Tongass forest</a>, the <a href="https://www.ecowatch.com/tag/keystone-xl" target="_self">Keystone XL</a> pipeline, and the <a href="https://www.ecowatch.com/dakota-access-pipeline-shut-down-2646355663.html" target="_self">Dakota Access</a> pipeline, is a gift to industry that the Trump administration has tried to fast track. All those projects could be reversed if a Democratic administration takes office in January, according to <a href="https://www.washingtonpost.com/climate-environment/2020/07/24/pebble-mine-alaska-trump/" target="_blank">The Washington Post</a>.</p>

By Isabelle Gerretsen
"When I told people I was going to grow tomatoes in the desert, they thought I was crazy," Sky Kurtz, founder of Pure Harvest Smart Farms, told DW.
<p>With just an average 12 days of rain a year, less than 1% arable land, a desert location and an 80% import rate for food, the United Arab Emirates (UAE) seems an unfavorable place to set up a farm.</p><p>Kurtz is one of several entrepreneurs using high-tech farming techniques to boost crop production in the Emirates. Pure Harvest built the first climate-controlled greenhouse in Abu Dhabi in 2017. </p><p>Prompted by arid conditions and a desire for greater food security, the country is investing millions in technologies — such as vertical farming — that could make it an unlikely agricultural pioneer. </p><p>Vertical farms can grow a rich variety of different crops by stacking them in layers under LED lighting in climate-controlled greenhouses and watering them with mist or drip systems. The process is tailored to each crop's specific needs, resulting in high-yield, year-round harvests.</p><p>"It takes 30 to 40 days to grow leafy greens out in the field. We can grow that same crop in 10 to 12 days," says Marc Oshima, co-founder of Aerofarms. The company received funding from the Abu Dhabi Investment Office to build the capital's largest indoor vertical farm, with 800 different crops, by 2021.</p>
Water Scarcity and Fossil-Fuel Reliance
<p>The technology uses minimal land and up to 95% less water than conventional agriculture. </p><p>The hydroponics system places the plants' roots directly into a water-based and nutrient-rich solution instead of soil. This "closed loop" system captures and recirculates all the water, rather than allowing it to drain away — useful for a country like the UAE suffering from extremely high water stress.</p><p>Globally, agriculture accounts for 70% of freshwater withdrawals, and UAE is extracting groundwater faster than it can be replenished, according to the International Center for Biosaline Agriculture (ICBA).</p><p>"Water is very expensive over in the UAE, but energy is cheap as it is subsidized," says Jan Westra, a strategic business developer at Priva, a company providing technology to vertical farms.</p><p>The artificially controlled environment is energy intensive because the air conditioning and LED lights need a constant source of electricity.</p><p>This bringing forth of life in the desert could come at a high environmental cost. Most of that energy comes from carbon-emitting fossil fuels, even as the Middle Eastern country feel the effects of climate change.</p><p>By 2050 Abu Dhabi's average temperature is <a href="https://benthamopen.com/FULLTEXT/TOASCJ-13-56" target="_blank">predicted to increase by around 2.5°C</a> (36.5 F) in a business-as-usual scenario. Over the next 70 years patterns of rainfall are also expected to change.</p>Integrating Renewable Energy
<p>Although Pure Harvest is building a solar-powered farm in neighboring Saudi Arabia, its UAE operations get electricity from the carbon-intensive national grid.</p><p>Investing more in renewables "is a goal of ours," Kurtz told DW. He said the company has not set a clean energy target but is working on various green power projects, including a plan to integrate solar power generated in UAE into its operations. </p><p>However, Willem van der Schans, a researcher specializing in short supply chains at Wageningen University in the Netherlands, says sustainability and clean energy should be "inherent in the technology and included in plans when starting a vertical farm." </p><p>He argues that many vertical farming companies are not sustainable in terms of energy as they still view clean power as an optional "add-on."</p><p>Ismahane Elouafi, director general of the government funded ICBA in Abu Dhabi, acknowledges that vertical farming has some way to go before achieving "real sustainability," but she believes the innovations are "promising."</p><p>Improved battery storage, increasingly efficient LED lights and cheaper solar panels will help, she adds. </p>Local Solutions
<p>By 2050, the UAE government wants to generate almost half its energy from renewable sources.</p><p>Fred Ruijgt, a vertical farming specialist at Priva, argues that it's important to factor transport and refrigeration into the energy equation. Vertical farming uses more energy to grow crops than traditional agriculture, but because crops are grown locally, they do not have to be transported by air, sea or truck over long distances. </p><p>"The energy saving is difficult to calculate exactly, but the advantages of locally grown crops are huge," he says, adding that those grown in vertical farms not only use less water and pesticides, but that they also have a longer shelf life due to minimal transportation time. </p>Food Security and Coronavirus
<p>In 2018, the UAE set out its vision to become a hub for high-tech local food production.</p><p>Companies and investors have flocked to the region, attracted by the 0% corporate tax rate, low labor costs and cheap energy. With their help, UAE aims to reduce its reliance on imports and make its food system more resilient to shocks like climate change and pandemics. </p><p>Oshima from Aerofarms says the coronavirus pandemic has brought "greater appreciation of how fragile the supply chain is and raised questions about food safety and security."</p><p>When the UAE went into lockdown in April, imported supplies of perishable goods like vegetables fell and business boomed for local suppliers.</p><p>ICBA's Elouafi said they have helped keep the UAE well-stocked during the pandemic.</p><p>"With the help of local food production and adequate imports, there has been absolutely no shortage of food in the UAE," Elouafi told DW.</p><p>Climate change, however, poses an altogether more complex threat to the country in the long-term. Given climate change's likely impact on food production, she says vertical farming has shown it is "an economically viable proposition even with harsh climatic conditions."</p>From Your Site Articles

Critics charge the legislation induces poor communities to sell off their water rights. Pexels
By Eoin Higgins
Over 300 groups on Monday urged Senate leadership to reject a bill currently under consideration that would incentivize communities to sell off their public water supplies to private companies for pennies on the dollar.
<p><br/></p>
<p>"This bill is an egregious handout to giant water corporations which would embolden them to manipulate and fleece struggling communities—particularly communities of color," said Food & Water Action executive director Wenonah Hauter. "The fact that this bill is being touted as an 'environmental justice' measure makes it all the more nefarious."</p><p>Food & Water Action led the demand in a <a href="https://www.foodandwaterwatch.org/sites/default/files/opposition_to_the_voluntary_water_partnerships_for_distressed_communities_act.pdf" target="_blank">letter</a> taking aim at the "Voluntary Water Partnership for Distressed Communities Act," described in the document as "inappropriate, unjust, and unreasonable."</p><p>"From California to Montana to New Jersey, we've seen how privatizing water harms communities, whether it's higher bills or dirtier water," Donald Cohen, executive director of In the Public Interest, said in a statement. "It's simple: water is a basic human right, which means let's keep it in public hands."</p><p>The bill was introduced by Sens. Tammy Duckworth (D-Ill.) and Mike Braun (R-Ind.) and acts as an amendment to the America's Water Infrastructure Act of 2020. Critics charge the legislation induces poor communities to sell off their water rights. </p>
<div id="fea63" class="rm-shortcode" data-rm-shortcode-id="9a6f211c2bc5aedd34837944cb8eeedf"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1281000111481294849" data-partner="rebelmouse"><div style="margin:1em 0">Water in Illinois is overwhelmingly public. Why is Tammy Duckworth sponsoring a bill that aims to change that? https://t.co/1V36Kkd99s</div> — The American Prospect (@The American Prospect)<a href="https://twitter.com/TheProspect/statuses/1281000111481294849">1594249201.0</a></blockquote></div>
<p>As the <em>American Prospect</em>'s Robert Kuttner <a href="https://prospect.org/environment/privatizing-our-public-water-supply/" target="_blank">explained</a>, doing so would likely spell disaster for affected communities:</p><blockquote>Privatized systems are typically less reliable, far more expensive, and prone to corrupt deal-making. The average community with privatized water paid 59% more than those with government supplied water. In New Jersey, which has more private water than most, private systems charged 79% more. In Illinois, they charged 95% more. Private water corporations have also been implicated in environmental disasters. The French multinational, Veolia, issued a report in 2015 certifying that Flint, Michigan's water system met EPA standards, but neglected to mention high lead concentrations.<br></blockquote><p>"We know that Wall Street actors target Black and brown communities in moments of crisis to enrich themselves and Wall Street-backed water companies see opportunity in this moment," Maurice BP-Weeks, co-executive director of letter signatory Action Center on Race and the Economy, said in a statement.</p><p>BP-Weeks added that incentivizing water privatization at such a vulnerable moment for poor communities in the country is exactly the wrong move for what the crisis demands. </p><p>"As communities across the country search for relief from the ongoing pandemic, it would be short sighted and misguided to pass a bill that encourages the privatization of water systems," said BP-Weeks. "It is our government's job to protect our most vulnerable communities, not put them up for sale."</p>

The human body comprises around 60% water.
It's commonly recommended that you drink eight 8-ounce (237-mL) glasses of water per day (the 8×8 rule).
<p>Although there's little science behind this specific rule, staying hydrated is important.</p><p>Here are 7 evidence-based health benefits of drinking plenty of water.</p>
<p><em>Reposted with permission from </em><a href="https://www.healthline.com/" target="_blank"><em>Healthline</em></a><em>. For detailed source information, please view the original article on </em><em><a href="https://www.healthline.com/nutrition/7-health-benefits-of-water" target="_blank">Healthline</a></em><em>.</em></p>
1. Helps Maximize Physical Performance
<p>If you don't stay hydrated, your physical performance can suffer.</p><p>This is particularly important during intense exercise or high heat.</p><p>Dehydration can have <a href="https://www.healthline.com/health/how-to-tell-if-youre-dehydrated" target="_blank">a noticeable effect</a> if you lose as little as 2% of your body's water content. However, it isn't uncommon for athletes to lose as much as 6–10% of their water weight via sweat.</p><p>This can lead to altered body temperature control, reduced motivation, and increased fatigue. It can also make exercise feel much more difficult, both physically and mentally.</p><p>Optimal hydration has been shown to prevent this from happening, and it may even reduce the <a href="https://www.healthline.com/health/oxidative-stress" target="_blank">oxidative stress</a> that occurs during high intensity exercise. This isn't surprising when you consider that muscle is about 80% water.<a href="https://pubmed.ncbi.nlm.nih.gov/19344695" target="_blank"><span></span></a></p><p>If you exercise intensely and tend to sweat, staying hydrated can help you perform at your absolute best.</p><p><strong>Summary</strong></p><p><strong></strong>Losing as little as 2% of your body's water content can significantly impair your physical performance.</p>2. Significantly Affects Energy Levels and Brain Function
<p>Your brain is strongly influenced by your hydration status.</p><p>Studies show that even mild dehydration, such as the loss of 1–3% of body weight, can impair many aspects of brain function.</p><p>In a study in young women, researchers found that fluid loss of 1.4% after exercise impaired both mood and concentration. It also increased the frequency of headaches.</p><p>Many members of this same research team conducted a similar study in young men. They found that fluid loss of 1.6% was detrimental to working memory and increased feelings of anxiety and fatigue.<a href="https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/mild-dehydration-impairs-cognitive-performance-and-mood-of-men/3388AB36B8DF73E844C9AD19271A75BF/core-reader" target="_blank"></a></p><p>A fluid loss of 1–3% equals about 1.5–4.5 pounds (0.5–2 kg) of body weight loss for a person weighing 150 pounds (68 kg). This can easily occur through normal daily activities, let alone during exercise or high heat.</p><p>Many other studies, with subjects ranging from <a href="https://www.healthline.com/health/parenting/signs-of-dehydration-in-toddlers" target="_blank">children</a> to <a href="https://www.healthline.com/health/symptoms-of-dehydration-in-elderly" target="_blank">older adults</a>, have shown that mild dehydration can impair mood, memory, and brain performance.</p><p><strong>Summary</strong></p><p><strong></strong>Mild dehydration (fluid loss of 1–3%) can impair energy levels, impair mood, and lead to major reductions in memory and brain performance.</p>3. May Help Prevent and Treat Headaches
<p>Dehydration can trigger <a href="https://www.healthline.com/health/dehydration-headache" target="_blank">headaches</a> and migraine in some individuals.<span></span></p><p>Research has shown that a headache is one of the most common symptoms of dehydration. For example, a study in 393 people found that 40% of the participants experienced a headache as a result of dehydration.</p><p>What's more, some studies have shown that drinking water can help relieve headaches in those who experience frequent headaches.</p><p>A study in 102 men found that drinking an additional 50.7 ounces (1.5 liters) of water per day resulted in significant improvements on the Migraine-Specific Quality of Life scale, a scoring system for <a href="https://www.healthline.com/health/migraine-symptoms" target="_blank">migraine symptoms</a>.<a href="https://academic.oup.com/fampra/article/29/4/370/492787" target="_blank"></a></p><p>Plus, 47% of the men who drank more water reported headache improvement, while only 25% of the men in the control group reported this effect.<a href="https://academic.oup.com/fampra/article/29/4/370/492787" target="_blank"></a></p><p>However, not all studies agree, and researchers have concluded that because of the lack of high quality studies, more research is needed to confirm how increasing hydration may help improve headache symptoms and decrease headache frequency.<a href="https://pubmed.ncbi.nlm.nih.gov/26200171" target="_blank"></a></p><p><strong>Summary</strong></p><p><strong></strong>Drinking water may help reduce headaches and headache symptoms. However, more high quality research is needed to confirm this potential benefit.</p>4. May Help Relieve Constipation
<p><a href="https://www.healthline.com/health/constipation" target="_blank">Constipation</a> is a common problem that's characterized by infrequent bowel movements and difficulty passing stool.</p><p>Increasing fluid intake is often recommended as a part of the treatment protocol, and there's some evidence to back this up.</p><p>Low water consumption appears to be a risk factor for constipation in both younger and older individuals.</p><p>Increasing hydration may help decrease constipation.</p><p><a href="https://www.healthline.com/nutrition/mineral-water-benefits" target="_blank">Mineral water</a> may be a particularly beneficial beverage for those with constipation.</p><p>Studies have shown that mineral water that's rich in magnesium and sodium improves bowel movement frequency and consistency in people with constipation.<a href="http://www.ncbi.nlm.nih.gov/pmc/articles/PMC5334415" target="_blank"></a></p><p><strong>Summary</strong></p><p><strong></strong>Drinking plenty of water may help prevent and relieve constipation, especially in people who generally don't drink enough water.</p>5. May Help Treat Kidney Stones
<p>Urinary stones are painful clumps of mineral crystal that form in the urinary system.</p><p>The most common form is <a href="https://www.healthline.com/health/kidney-stones" target="_blank">kidney stones</a>, which form in the kidneys.</p><p>There's limited evidence that water intake can help prevent recurrence in people who have previously gotten kidney stones.<a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD004292.pub3/full" target="_blank"></a></p><p>Higher fluid intake increases the volume of urine passing through the kidneys. This dilutes the concentration of minerals, so they're less likely to crystallize and form clumps.</p><p>Water may also help prevent the initial formation of stones, but studies are required to confirm this.</p><p><strong>Summary</strong></p><p><strong></strong>Increased water intake appears to decrease the risk of kidney stone formation.</p>6. Helps Prevent Hangovers
<p>A hangover refers to the unpleasant symptoms experienced after drinking <a href="https://www.healthline.com/nutrition/alcohol-good-or-bad" target="_blank">alcohol</a>.</p><p>Alcohol is a diuretic, so it makes you lose more water than you take in. This can lead to dehydration.</p><p>Although dehydration isn't the main cause of hangovers, it can cause symptoms like thirst, fatigue, headache, and dry mouth.</p><p>Good ways <a href="https://www.healthline.com/nutrition/7-ways-to-prevent-a-hangover" target="_blank">to reduce hangovers</a> are to drink a glass of water between drinks and have at least one big glass of water before going to bed.</p><p><strong>Summary</strong></p><p><strong></strong>Hangovers are partly caused by dehydration, and drinking water can help reduce some of the main symptoms of hangovers.</p>7. Can Aid Weight Loss
<p>Drinking plenty of water can help you <a href="https://www.healthline.com/nutrition/how-to-lose-weight-as-fast-as-possible/" target="_blank">lose weight</a>.</p><p>This is because water can increase satiety and boost your metabolic rate.</p><p>Some evidence suggests that increasing water intake can promote weight loss by slightly increasing your metabolism, which can increase the number of calories you burn on a daily basis.</p><p>A 2013 study in 50 young women with overweight demonstrated that drinking an additional 16.9 ounces (500 mL) of water 3 times per day before meals for 8 weeks led to significant reductions in body weight and body fat compared with their pre-study measurements.</p><p>The timing is important too. Drinking water half an hour before meals is the most effective. It can make you feel more full so that you <a href="https://www.healthline.com/nutrition/35-ways-to-cut-calories" target="_blank">eat fewer calories</a>.</p><p>In one study, dieters who drank 16.9 ounces (0.5 liters) of water before meals lost 44% more weight over a period of 12 weeks than dieters who didn't drink water before meals.</p>The Bottom Line
<p>Even mild dehydration can affect you mentally and physically.</p><p>Make sure that you <a href="https://www.healthline.com/nutrition/how-much-water-should-you-drink-per-day" target="_blank">get enough water each day</a>, whether your personal goal is 64 ounces (1.9 liters) or a different amount. It's one of the best things you can do for your overall health.</p>From Your Site Articles

Global heating imposes a harsh cost at the most critical time of all: the moment of spawning. Pxfuel
By Tim Radford
German scientists now know why so many fish are so vulnerable to ever-warming oceans. Global heating imposes a harsh cost at the most critical time of all: the moment of spawning.
<p>"Our findings show that, both as embryos in eggs and as adults ready to mate, fish are far more sensitive to heat than in their larval stage or as sexually mature adults outside the mating season," said <a href="https://www.researchgate.net/profile/Flemming_Dahlke" target="_blank">Flemming Dahlke, a marine biologist</a> with the <a href="https://www.awi.de/" target="_blank">Alfred Wegener Institute at Bremerhaven</a>.</p><p>"On the global average, for example, adults outside the mating season can survive in water that's up to 10°C warmer than adults ready to mate, or fish eggs, can."</p><p>The finding – if it is confirmed by other research – should clear up some of the puzzles associated with fish numbers. There is clear evidence, established repeatedly over the decades, that <a href="https://climatenewsnetwork.net/ocean-heatwaves-drive-more-fish-north/" target="_blank">fish are responding to climate change</a>.</p><p>But almost three fourths of the planet is blue ocean, and <a href="https://climatenewsnetwork.net/hunger-threat-as-tropical-fish-seek-cooler-waters/" target="_blank">at depth is responding far more slowly</a> than the land surface to global heating fueled by fossil fuel exploitation that releases greenhouse gases.</p>
Nearing the Brink
<p>Since <a href="https://climatenewsnetwork.net/abundant-fish-need-cool-seas-and-protection/" target="_blank">fish in the temperate zones already experience a wide variation</a> in seasonal water temperatures, it hasn't been obvious why species such as <a href="https://climatenewsnetwork.net/sardines-swim-into-northern-waters-to-keep-cool/" target="_blank">cod have shifted nearer the Arctic, and sardines have migrated to the North Sea</a>.</p><p>But <a href="https://climatenewsnetwork.net/ocean-warming-spurs-marine-life-to-rapid-migration/" target="_blank">marine creatures are on the move</a>, and although there are other factors at work, including overfishing and <a href="https://climatenewsnetwork.net/fish-cant-smell-well-in-more-acidic-seas/" target="_blank">the increasingly alarming changes in ocean chemistry</a>, thanks to ever-higher levels of dissolved carbon dioxide, temperature change is part of the problem.</p><p>The latest answer, Dr Dahlke and his colleagues report in the journal <a href="https://science.sciencemag.org/cgi/doi/10.1126/science.aaz3658" target="_blank">Science</a>, is that many fish may already be living near the limits of their thermal tolerance.</p><p>The temperature safety margins during the moments of spawning and embryo might be very precise, and over hundreds of thousands of years of evolution, marine and freshwater species have worked out just what is best for the next generation. Rapid global warming upsets this equilibrium.</p><p>The Bremerhaven scientists looked at experiments, observations and recorded data for the life cycles of 694 marine and freshwater species, to decide that oxygen supply is the key decider of reproductive success. Warmer waters carry less dissolved oxygen. Embryo fish have no gills: they cannot simply take in deeper breaths.</p><p>Fish about to mate are busy producing extra mass in the form of sperm and egg cells: this additional body mass also needs oxygen. Even at lower temperatures, piscine cardiovascular systems are under stress.</p><p>So the reasoning follows that, if global heating continues, climate change and rising water temperatures are likely to affect the reproduction of perhaps 60% of all fish species.</p><p>"Some species might successfully manage this change," Dr Dahlke said. "But if you consider the fact that fish have adapted their mating patterns to specific habitats over extremely long timeframes, and have tailored their mating cycles of specific ocean currents and food sources, it has to be assumed that being forced to abandon their normal spawning areas will mean major problems for them."</p>

Naegleria fowleri (commonly referred to as the "brain-eating amoeba") is a free-living microscopic amoeba (single-celled living organism). Centers for Disease Control
As if the surging cases of coronavirus weren't enough for Floridians to handle, now the state's Department of Health (DOH) has confirmed that a person in the Tampa area tested positive for a rare brain-eating amoeba, according to CBS News. The Florida DOH posted a warning to residents to remind them of the dangers of the rare single-celled amoeba that attacks brain tissue.
<p>The amoeba is known, scientifically, as <em>Naegleria fowleri</em>. Only four people have survived <em>Naegleria fowleri</em> in the U.S. between 1962 and 2016, out of 143 who contracted the disease, as <a href="https://www.independent.co.uk/news/world/americas/florida-brain-eating-amoeba-warning-naegleria-fowleri-a9603026.html" target="_blank">The Independent</a> reported. There have been only 37 cases reported in Florida since 1962, which makes up nearly 26 percent of all instances in the U.S.</p><p><em>Naegleria fowleri</em> is typically found in warm freshwater such as lakes, rivers and ponds. The Florida DOH has cautioned people who swim in those freshwater sources to be aware of the amoeba's possible presence, particularly when the water is warm, according to CNN.</p><p>The DOH did not disclose where in Hillsborough County the patient had contracted the amoeba, nor the patient's condition, according to The Independent.</p>
<p>The amoeba's deadly effects happen when it causes a rare infection of the brain called primary amebic meningoencephalitis (PAM), which destroys brain tissue and is usually fatal, according to <a href="https://www.foxnews.com/health/brain-eating-amoeba-infection-florida-rare-hillsborough-county-health" target="_blank">Fox News</a>.</p><p>"Infections can happen when contaminated water enters the body through the nose," the DOH said in its letter.</p><p>After the amoeba enters the nose through contaminated water, it then travels to the brain where it causes PAM, according to health officials.</p>
<p>"Infections usually occur when temperatures increase for prolonged periods of time, which results in higher water temperatures and lower water levels," health officials stated in their letter.</p><p>Health officials recommend using a nose plug, pinching your nose or keeping your head above water to avoid the amoeba. They also recommend avoiding water where conditions are ripe for the amoeba to thrive, such as warm freshwater around power plants and shallow fresh water during periods of high water temperature.</p><p>"Adverse health effects on humans can be prevented by avoiding nasal contact with the waters, since the amoeba enters through nasal passages," the DOH said, as CNN reported.</p>
<p>As CNN pointed out, the ancient tradition of treating congested sinuses with a neti pot can also increase the risk of infection.</p><p>"Use only boiled and cooled, distilled, or sterile water for making sinus rinse solutions for neti pots or performing ritual ablutions," the DOH said.</p><p>It is also possible to contract the amoeba in swimming pools that are not properly chlorinated. Since it's only contracted through the nose, there is no chance of developing PAM from drinking it, according to CBS News.</p><p>As CBS News noted, the typical symptoms of a <em>Naegleria fowleri</em> infection include severe frontal headache, fever, nausea and vomiting. Later symptoms include stiff neck, seizures, altered mental status, hallucinations and coma.</p>
<p>Signs of infection typically start a few days after swimming or other nasal exposure to contaminated water. People usually die within 1 to 18 days after symptoms begin.</p><p>"It is essential to seek medical attention right away, as the disease progresses rapidly after the start of symptoms," the health department said.</p><p>The DOH added that "this disease is rare and effective prevention strategies can allow for a safe and relaxing summer swim season," as The Independent reported.</p>
