Use of Colorado River water in the three states of the river's lower basin fell to a 33-year low in 2019, amid growing awareness of the precarity of the region's water supply in a drying and warming climate.
Raising Lake Mead<p>Just five years ago, in 2015, the three states were making use of their entire 7.5-million-acre-foot allotment. By statute and tradition, the basin is divided into a lower basin, where use is higher, and an upper basin, which includes Colorado, New Mexico, Utah, and Wyoming. The basins have different water allocation systems and rules governing its use.</p><p>In the lower basin, Arizona's annual allocation is 2.8 million acre-feet, but last year it used just 2.5 million. Nevada used 233,000 of its 300,000 acre-feet. The big savings were in California, which used only 3.8 million of its 4.4 million acre-feet. California hasn't used that little water from the Colorado since the 1950s, Fleck said.</p><p>The drop in California last year is due in large part to Metropolitan Water District, which consumed only 537,000 acre-feet. Five years ago, the district's tally was around 1 million acre-feet per year. Urban conservation and development of local water sources have played a large role in the decline, but the district's Colorado River water use is also influenced by snow levels in the Sierra Nevada mountains. When more water is available to be imported from the northern part of the state, as it was last year, the district leans less heavily on the Colorado River.</p>

It is far too easy to view scarcity and poor quality of water as issues solely affecting emerging economies. While the images of women and children fetching water in Africa and a lack of access to water in India are deeply disturbing, this is not the complete picture.
The Past Is No Longer a Guide to the Future<p>We get ever closer to "day zeros" — the point at when municipal water supplies are switched off — and tragedies such as Flint. These are not isolated stories. Instead they are becoming routine, and the public sector and civil society are scrambling to address them. We are seeing "day zeros" in South Africa, India, Australia and elsewhere, and we are now detecting lead contamination in drinking water in cities across the U.S.<br></p><p>"Day zero" is the result of water planning by looking in the rear-view mirror. The past is no longer a guide to the future; water demand has outstripped supplies because we are tied to business-as-usual planning practices and water prices, and this goes hand-in-hand with the inability of the public sector to factor the impacts of climate change into long-term water planning. Lead in drinking water is the result of lead pipe service lines that have not been replaced and in many cases only recently identified by utilities, governments and customers. An estimated 22 million people in the U.S. are potentially using <a href="https://www.pnas.org/content/115/9/2078" target="_blank">lead water service lines</a>. This aging infrastructure won't repair or replace itself.</p><p>One of the most troubling aspects of the global water crisis is that those least able to afford access to water are also the ones who pay a disproportionately high percentage of their income for it. A report by <a href="https://www.wateraid.org/us/" target="_blank">WaterAid</a> revealed that a standard water bill in developed countries is as little as 0.1 percent of the income of someone earning the minimum wage, while in a country like Madagascar a person reliant on a tanker truck for their water supply would spend as much as 45 percent of their daily income on water to get just the recommended daily minimum supply. In Mozambique, families relying on black-market vendors will spend up to 100 times as much on water as those reached by government-subsidized water supplies.</p><p>Finally, we need to understand that the discussion of a projected gap between supply and demand is misleading. There is no gap, only poor choices around allocation. The wealthy will have access to water, and the poor will pay more for water of questionable quality. From Flint residents using bottled water and paying high water utility rates, to the poor in South Africa waiting in line for their allocation of water — inequity is everywhere.</p>
Water Inequity Requires Global Action — Now.<p>These troubling scenarios beg the obvious question: What to do? We do know that ongoing reports on the 'water crisis' are not going to catalyze action to address water scarcity, poor quality, access and affordability. Ensuring the human right to water feels distant at times.</p><p>We need to mobilize an ecosystem of stakeholders to be fully engaged in developing and scaling solutions. The public sector, private sector, NGOs, entrepreneurs, investors, academics and civil society must all be engaged in solving water scarcity and quality problems. Each stakeholder brings unique skills, scale and speed of impact (for example, entrepreneurs are fast but lack scale, while conversely the public sector is slow but has scale).</p><p>We also urgently need to change how we talk about water. We consistently talk about droughts happening across the globe — but what we are really dealing with is an overallocation of water due to business-as-usual practices and the impacts of climate change.</p><p>We need to democratize access to water data and actionable information. Imagine providing anyone with a smartphone the ability to know, on a real-time basis, the quality of their drinking water and actions to secure safe water. Putting this information in the hands of civil society instead or solely relying on centralized regulatory agencies and utilities will change public policies.</p>

Anthony Spaniola knew something was off with his town's water. He read accounts in the Detroit Free Press and attended community meetings hosted by state health and environment agencies. Until last summer Spaniola was concerned but didn't think the situation was out of control.
Then he saw foam on Van Etten Lake.
Behind barbed-wire fences at this camp in northern Jordan, about 33,000 Syrians—half of them children—exist uneasily, housed in rows of rudimentary shelters that barely protect them from the winter cold.
Drinking water must be brought in daily by dozens of tanker trucks or pumped from desert boreholes that overexploit Jordan's largest groundwater basin.

The head of the U.S. Environmental Protection Agency (EPA) pledged that lead regulations will be a prominent feature of the agency's work in 2018—but that work will take longer than anticipated.
The agency expects that a revision to federal rules that are designed to reduce the risk of lead in drinking water will be published in draft form in August 2018, a seven-month delay from a timetable announced this summer.
The U.S. Environmental Protection Agency (EPA) confirmed that Hurricane Harvey damaged a protective cap at a Superfund site along the San Jacinto River, near Houston, and caused a spike in chemical levels in the water.
Water samples from one of 14 monitoring sites at the San Jacinto waste pits indicated levels of dioxin above 70,000 parts per trillion, more than 2,000 times higher than the site's cleanup goal of 30 parts per trillion. Dioxin is a cancer-causing chemical that stays in the environment for hundreds of years before breaking down.

A year after the most intense bloom of toxic algae on record engulfed Lake Erie, the lake is set to get a reprieve this summer. Federal forecasters at the National Oceanic and Atmospheric Administration predict this year's bloom will register a 5.5 in severity, about half the level recorded last year and significantly less than the bloom in 2014 that shut down water supplies for nearly half a million people in Toledo, Ohio.

Still, work to rid the shallowest Great Lake from the annual blooms that contaminate drinking water, close beaches and create aquatic "dead zones" is far from over, warned researchers and water managers gathered at Ohio State University's Stone Laboratory last week. Hundreds of metric tons of phosphorus, a nutrient contained in fertilizer, manure and sewage, continue to wash down the Maumee River each year into Lake Erie's western basin, where the influx fuels the bloom of blue-green algae.
The small size predicted for this year's bloom is more a function of dry weather in the Maumee Basin rather than big reductions in phosphorus. Just as record rains in the basin last year triggered a massive bloom, dry conditions this spring meant less water to carry phosphorus off the land and into the lake. As a result, total "loads" of the type of phosphorus that can be used by algae are expected to be about one-third the amount washed into the lake last year.
"The reality is that rain is really driving our loads at this point in time," said Laura Johnson, director of the National Center for Water Quality Research at Heidelberg University, which tracks the nutrients flowing into Lake Erie.

That means one dry year with a small algal bloom does not indicate the problem is solved. It will take a 40 percent reduction in the amount of phosphorus flowing down the Maumee and other Lake Erie tributaries to control the blooms in the long-run, according to new targets adopted in February by the U.S. and Canada. Further, the blooms in Lake Erie are just one facet of the burgeoning nutrient pollution problem across the nation and the globe. Attention this year is focused on the noxious blooms along Florida's Treasure Coast, where the state's governor declared a state of emergency in June. But blooms also plague Green Bay in Lake Michigan, Lake Taihu in China and the Murray-Darling River in Australia. The oxygen-depleted aquatic dead zones created when blooms die regularly form in Lake Erie, the Gulf of Mexico and the Baltic Sea.
Spurred by the poisoning of Toledo's drinking water supply in 2014—and a history of algal blooms dating to the mid-20th century—the research and management efforts being implemented in the Lake Erie watershed to curb phosphorus runoff are an important guidepost for these other systems.
"This is a state, country and global issue," said Chris Winslow, interim director of Stone Laboratory. "We're at the cutting edge of many of these studies right now. A lot of this is going to inform what a lot of people do throughout the country."
A Plan for Lake Erie
Over the past year and following decades of study, the Great Lakes states and provinces took their first concrete steps toward curbing phosphorus pollution and algal blooms in Lake Erie. An agreement signed between the premier of Ontario and the governors of Ohio and Michigan last June set an ambitious goal to cut phosphorus flowing into western Lake Erie by 40 percent by 2025. It also set the interim goal of a 20 percent reduction by 2020. The state-level commitment was followed by the adoption in February of 40 percent reduction targets under the Great Lakes Water Quality Agreement (GLWQA). While there is no timeline under the GLWQA, it does require the U.S. and Canada to develop domestic action plans by 2018 outlining how they will make the phosphorus cuts.
To meet those goals, land and water managers will need to focus on reducing runoff from farms in the Maumee River Basin, according to a study led by researchers at the University of Michigan. While stormwater runoff, discharges from municipal wastewater plants and septic systems can all contribute phosphorus, scientists estimate nearly 85 percent of the phosphorus flowing into Lake Erie from the Maumee comes from farm fertilizers and manure.
The study, released in April, analyzed a variety of agricultural management scenarios using watershed models to estimate how the practices would affect phosphorus discharges. In general, it found that agricultural practices meant to trap phosphorus on land will need to be widely adopted and that better results occur when those practices are targeted on land that currently releases high levels of phosphorus.
Specifically, only two scenarios achieved the new targets outlined under the GLWQA. The first would require the conversion of 50 percent of cropland to uncultivated grassland and is considered highly unrealistic.
The second would require the subsurface application of phosphorus fertilizers on half of the cropland that currently loses the most phosphorus. That prevents the fertilizer from sitting on top of the soil, where it can be washed off by rain. The scenario also calls for the use of rye cover crops and the installation of "medium quality" buffer strips on 50 percent more cropland than implements these practices now. Cover crops store the phosphorus in their roots and leaves, keeping it out of the soil so it cannot wash away, while "buffer" strips of vegetation slow the rain running off of fields, filtering out phosphorus before it reaches streams. As of 2013, approximately 8 percent of farms in the Maumee watershed used a rye cover crop and 35 percent of farms used buffer strips.
In a demonstration of agriculture's important role in reducing phosphorus, the study also examined a scenario in which all point sources of phosphorus—those that come out of a pipe, such as from a municipal wastewater plant—were eliminated completely. In that scenario, total phosphorus was reduced by just 5 percent and dissolved reactive phosphorus—the kind most usable by algae—was reduced by 10 percent.
"The 40 percent [target] is doable, but it's going to be a heavy lift," said Gail Hesse, director of the National Wildlife Federation's Great Lakes Water Program, speaking at the Stone Laboratory event. "It's going to need a steep investment and a steep ramp-up in our efforts to reach that target."

On Tuesday, residents of Flint, Michigan were invited to bring their children to a local elementary school for a “Lead Testing and Family Fun Night." Combining a school carnival with medical tests to check children's blood for abnormally high levels of lead, the event was an example of the bizarre circumstances that families are contending with in Flint, Michigan's seventh largest city.
A series of public decisions, driven by misguided management practices and ideological principles that backfired, converged during the past 20 months to poison the city's drinking water and cause one of the most severe public health threats in the U.S. The extent of the risk to Flint's residents is not clear.
Flint's crisis is the third time during the administration of Republican Gov. Rick Snyder that decisions about water supply and water quality at the most senior levels of state government have put state residents in harm's way. In 2014, again as a result of the governor's decision to appoint an emergency manager in Detroit, drinking water services were cut off for thousands of city residents said to be in arrears on their water bills. But water services for many of the city's largest commercial water consumers, which owed the city water department millions of dollars in unpaid charges, were not halted.
The Snyder administration, according to business owners and residents in northern Michigan, has been slow to respond to the threat of a major Great Lakes oil spill from two 63-year-old pipelines that transport 540,000 barrels of oil a day across the Straits of Mackinac at the top of Lake Michigan. An environmental law group in Traverse City, For the Love of Water, has argued that other existing onshore pipelines are available to transport oil to Great Lakes refineries and that Gov. Snyder has the legal authority to shut down Line 5 and prevent what the group called an “imminent risk."
Flint's Water Unravels
Flint's water troubles began in April 2014, when the city of 102,000 residents in southeastern Michigan began sourcing its water from the nearby Flint River instead of receiving Lake Huron water from its longtime water supplier, the Detroit city water department. The move, made by emergency managers appointed by the state to bring an economically ailing Flint back to fiscal health, was estimated to save the city $US 5 million while it awaited the construction of a new pipeline to Lake Huron.
The plan, which was strong on the value of “cost-saving," but received scant evaluation for its technical feasibility, quickly unraveled. Over the next year and a half, a series of public announcements and troubling disclosures, many of them first reported by investigative journalist Curt Guyette, described Flint's deteriorating water quality and growing public dismay.
First, the city issued several boil water advisories in the summer of 2014. Then, in January 2015, Flint violated the U.S. Safe Drinking Water Act because its water contained high levels of total trihalomethanes or THM, byproducts of the water treatment process that, over time, can increase the risk of cancer and cause health problems of the liver, kidneys and central nervous system. Finally, two research studies in the fall of 2015 found that the new water source was corroding aging water pipes, leaching lead into the system and very likely causing a spike in lead levels in the blood of Flint's children. Lead exposure can impair both mental and physical development in children, sometimes causing “profound and permanent adverse health effects," according to the World Health Organization.
State Slow to Respond
Throughout the crisis, Gov. Snyder appeared indifferent while state officials defended the emergency manager's actions and repeatedly rejected claims that there was anything wrong with Flint's water. As evidence of serious contamination mounted, the Snyder administration insisted the city's water was safe to drink.
Gov. Snyder did not acknowledge the unsafe condition of the city's water problems until Sept. 30, 2015.
“In terms of a mistake, we found there are probably things that weren't as fully understood when that switch was made," Snyder told reporters, according to MLive. “Again, we're looking at making sure they're within safe limits according to the federal government."
The governor apologized to the city in December.
“I want the Flint community to know how very sorry I am that this has happened," Snyder said in a statement. “And I want all Michigan citizens to know that we will learn from this experience, because Flint is not the only city that has an aging infrastructure."
The same day, the governor accepted the resignation of Dan Wyant, the director of the Michigan Department of Environmental Quality. Both Snyder's apology and Wyant's resignation came on the heels of a letter to the governor from the state-appointed Flint Water Advisory Task Force. The task force blatantly blamed Michigan Department of Environmental Quality for Flint's water problems, MLive reported, writing to the governor, “We believe the primary responsibility for what happened in Flint rests with the Michigan Department of Environmental Quality."
In October, the state authorized Flint to switch back to the Detroit water system. The city also began adding phosphates to its water in December to help rebuild a protective coating inside pipes damaged by the corrosive Flint River. Meanwhile, state and city programs are providing residents with water filters, bottled water and lead testing to help ensure safe water.
Cost-Saving Move Backfires
Critics of the Snyder administration's management of Flint's fiscal and public health turmoil note that the cost to the city and the state of the administration's “cost-saving" strategy is likely to be considerable. The state has allocated $US10 million to “test the water, distribute water filters and help in other ways." The money comes on top of the $US6 million price tag to switch Flint back to the Detroit water system.
Personal and class action lawsuits brought by plaintiffs seeking compensation for health damages could be inordinately expensive. The reasons: blood tests revealed elevated concentrations of lead in the tissues of many residents. And a bevy of documents uncovered by Guyette, other reporters and researchers indicate that state officials knew of serious problems much sooner, but failed to act.
“In their short-sighted effort to save a buck, the leaders who were supposed to be protecting Flint's citizens instead left them exposed to dangerously high levels of lead contamination," Michael Steinberg, legal director for the American Civil Liberties Union of Michigan, said in a November press release announcing an intent to sue state and city officials over the water crisis.
Echoes of Flint Around the World
Flint's story of water dangers fostered by ideology, neglect and indifference is, in many ways, a central national and global challenge of the 21st century.
Governments are forgoing investments in critical infrastructure or failing to take changing markets and fast-changing environmental conditions into account. The result, in places like Flint or Sao Paulo, Johannesburg and Mumbai, is decrepit, inadequate water systems that leave residents with unsafe water—or no water at all. In the Midwest U.S. and in India, it is depleted aquifers that threaten food production. In Lake Erie and Lake Taihu, it is runaway nutrient pollution that fuels toxic algae blooms. On a global scale, the collective procrastination on climate action means countries must now make drastic cuts in their carbon emissions to avoid environmental collapse.
The fallout when water systems break down is swift and unrelenting. A severe, two-year drought in Brazil nearly spelled disaster for Sao Paulo last year. The city contemplated the daunting prospect of 20 million residents without water. Inadequate, leaky infrastructure compounded the problem.
Millions of people living in Wuxi, China could not use their tap water for days in 2007 due to a toxic algae bloom in Lake Taihu.
And then there is Flint, which had no water problem until the state governor, driven by ideological principles of reducing taxes and administrative costs, appointed an emergency manager who decided to save $US5 million, a relative pittance in big city budgets, without carefully evaluating the consequences. That misguided and unnecessary decision affecting a major public service put people in danger and resulted in economic costs that already are three times higher than what the emergency manager expected to save.
An Expensive Problem
In the case of Flint and other cities with aging infrastructure and no source of revenue from a U.S. Congress devoted to the same principles of tax reduction and disinvestment, the outlook is disturbing. The U.S. Environmental Protection Agency estimates that utilities in the U.S. need to spend $US633 billion over the next two decades to supply water and to treat sewage. A 2012 report by the American Water Works Association said restoring and expanding water systems over the next 25 years could cost $US1 trillion.
Growing infrastructure repair bills and inadequate financial support from the federal government mean cities are raising water rates that inhibit the ability of some citizens to pay and could affect economic competitiveness.
“This shouldn't have to be Americans' fate. Once upon a time, this country dreamed of big and ambitious interventions to help its residents live safe, secure and comfortable lives," Guyette wrote in The Nation in July 2015. He added, “Getting Congress to come up with the cash is a decidedly tough task in an era when lawmakers eschew any form of tax hike, focusing instead on attempts to rein in the federal budget by hacking away at established programs."
