DIY water test kits can be easily bought online and range in cost from $20 and up to $150. The lower priced versions detect the most common drinking water contaminants such as iron, copper, lead, bacteria, pesticides, nitrates, nitrites, chlorine, pH and hardness. The more expensive kits let you send a water sample to a professional lab where they test it for more than 170 contaminants.
If you have determined that your tap water contains contaminants that exceeds safe levels, you might want consider filters to reduce or eliminate the contaminants or even bottled water for serious contamination. Both options, however, have caveats.
First, not every filter is created equal. The popular Everyday Brita pitcher, for instance, only filters four contaminants—chlorine (just the taste and odor), copper, cadmium and mercury. In fact, according to the company's own website, Brita's only product that filters lead is its faucet system that attaches to your tap.
There's some debate that filters like Brita's are only good for tastier water, not healthier water. As the Daily Beast noted, "Unlike municipal water, personal filters aren't subject to any government oversight or regulation, but the independent, nonprofit NSF International provides certification and standards for many filters on the market."
Like Goldilocks, you want to find a filter that's just right. Let's say you've detected too much mercury or benzene in your water and you don't want it in your glass. The Environmental Working Group has comprehensive water filter database that lets you select exactly which nasties you don't want to drink and the site will pop up with the best filter systems for your home and your budget. If you are really determined to have very clean water and have the money to do so, you might consider a combination of filtration methods, like installing an activated carbon filter faucet and under-sink reverse osmosis system.
As for bottled water, more than $100 billion is spent each year on bottled water around the globe, with Americans alone spending nearly $12 billion on bottled water each year. Clearly, there is a demand for bottled water, but is it any safer?
While the Meyocks survey found that more than half of Americans (53 percent) believe that bottled water is safer than their tap water and nearly two of three Americans (66 percent) prefer the taste of bottled water to tap water, "tap water and bottled water are generally comparable in terms of safety," Katherine Zeratsky, a licensed dietician with the Mayo Clinic, states.
"So the choice of tap or bottled is mostly a matter of personal preference," she added.
In fact, some companies just sell bottled tap water from public sources. Bottled water companies may argue that their water is filtered or purified, but does that justify prices that are 240 to over 10,000 times more per gallon than the water flowing from your tap?
Additionally, the Environmental Working Group points out that while tap water suppliers are required to publish all their water quality tests, bottled water companies are not. The group found 38 contaminants in 10 popular brands. Not only that, some water bottles are made of #7 plastic, which can leach a harmful chemical called bisphenol-A (BPA) into the water it contains. Even if the bottle is made of recyclable material, most people do not bother recycling—about eight out of 10 plastic bottles end up in a landfill or the incinerator.
Here are some takeaways. You should definitely check if your local water supply is safe. If it's not safe—or if you're convinced it's not safe—consider a filter system and change your filters when required. Finally, do not drink bottled water unless there is no other option.
Unfortunately, clean drinking water is becoming increasingly scarce. As the drought-stricken West Coast can attest, pollutants are not the only threat to our precious H2O. Government officials in 40 out of 50 states expect water shortages to occur in some parts of their states in the next decade.
Luckily, engineers have identified the growing need for advanced water treatment, from California's Carlsbad Desalination Project, which aims to turn seawater into drinking water, to membrane filtration systems and microbial fuel cells that can turn sewage water into drinking water.
"The aim," as U.C. Riverside's engineers tout about these developing technologies, "is to make recycled water good enough to drink." We say cheers to that.

My name is Arkilaus Kladit. I'm from the Knasaimos-Tehit tribe in South Sorong Regency, West Papua Province, Indonesia. For decades my tribe has been fighting to protect our forests from outsiders who want to log it or clear it for palm oil. For my people, the forest is our mother and our best friend. Everything we need to survive comes from the forest: food, medicines, building materials, and there are many sacred sites in the forest.

Overthinkers are people who are buried in their own obsessive thoughts. Imagine being in a large maze where each turn leads into an even deeper and knottier tangle of catastrophic, distressing events — that is what it feels like to them when they think about the issues that confront them.
Ruminating<p>According to the late Susan Nolen-Hoeksema, a professor of psychology at Yale University, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5796420/" target="_blank">ruminating</a> involves replaying a problem over and over in your mind. We ruminate by obsessing over our thoughts and thinking repetitively about various aspects of a past situation.</p><p>It usually involves regret, self-loathing and self-blaming. Rumination is associated with the development of depression, anxiety and eating disorders. </p><p>People prone to such patterns of thought may, for example, overanalyze every single detail of a relationship that breaks up. They often blame themselves for what has happened and are overcome with regret, with typical thoughts being: </p><p>- I should have been more patient and more supportive. </p><p>- I have lost the most perfect partner ever. </p><p>- No one will love me again.</p>
Worrying<p>Worrying is wanting to predict the future. It involves negative thoughts about things that might and might not happen.</p><p>- They'll not like me in the interview; they'll not give me the job. </p><p>- I haven't heard back from other employers. How long will I be unemployed?</p><p>These thoughts are energy-draining and distressing. They could happen to anyone under stress. But when you reach the point where your thoughts and worrying are preventing you from doing what you want to do — from living your life to the fullest — then you should take action.</p>
Catch Yourself Overthinking<p>Reuben Berger, a psychotherapist at the university hospital in the western German city of Bonn, recommends several practical steps that you could employ in your daily routine when you catch yourself worrying or ruminating.</p><p>One effective remedy, says Berger, is the <a href="https://www.uofmhealth.org/health-library/uf9938" target="_blank">thought-stopping technique.</a></p><p>"When the negative thoughts come or ruminations start, you say to yourself: 'Stop!,'" he says, adding that it is more effective when you actually say the word out loud.</p><p>He even recommends having a rubber band around your wrist to ping against yourself while saying the word. Adding a visual component by imagining a stop sign also makes the technique more powerful, he says.</p><p>The main idea here is conditioning yourself to stop the loop of worrying (making future predictions) or rumination (obsessing over past events).</p><p>Berger says the technique could take up to two weeks to take effect and that it needs to be practiced every day. "Consistency is very important," he says. </p>
Thoughts Are Just Thoughts<p>Another way of dealing with negative thoughts often used in modern therapy is realizing that thoughts aren't facts, says Berger.</p><p>He says it is important when we think something to ask: Is that real? Did that really happen? What is the worst thing that could happen?</p><p>Flight anxiety is one example where untrue thoughts are accepted as facts. Although air travel is the safest way to get around, people suffering from fear of flying accept their thoughts and fears as reality, then act upon them by refusing to fly.</p>
Mindfulness<p>Berger also recommends the use of mindfulness techniques, in which attention is paid to experiences in the moment without judging them, as a way of reducing worrying.</p><p>"Mindfulness helps you to distance yourself from your thoughts and to be more present in the moment," he says.</p><p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3432145/#R2" target="_blank">Several studies</a> have shown that mindfulness has a positive impact on reducing stress-related behaviors such as rumination and worrying, as focusing on the moment makes anxiety about other problems impossible.</p><p>Mindfulness can be practiced during routine activities by paying attention to your body and your surroundings. For instance, when you leave for work in the morning, you can focus on sensing the breeze, listen attentively to birds, feel the gravel under your feet and monitor your breath. </p>
Trick Your Brain Into Happiness<p>People plagued by obsessive thoughts do not always choose healthy ways like mindfulness to distract from them, however.</p><p> Dr. Edward Selby, a psychologist at Florida state university, has shown in a study that people try to avoid rumination by engaging in a range of uncontrolled behaviors, such as binge eating and substance abuse.</p><p>But he says that a much better way to overcome such distress is by distraction and shifting attention away from problems that are obsessing us.</p><p>There are many activities that can be used to distract from rumination, he says, and people should choose the one that works best for them. Here are some examples:</p><p>- Listen to music</p><p>- Read a book</p><p>- Take a hot shower</p><p>- Dance or exercise </p><p>- Talk to a friend (not about the problem)</p><p>- Watch a movie</p><p>- Mindfulness meditation</p>
Changing the Perception of Events<p>The way people perceive a situation largely influences their emotions and behavior. It is not the situation itself that determines how they feel, but rather the way they interpret it.</p><p>Reframing negative thoughts can lead to positive emotions and, subsequently, healthier behaviors — including a reduction in damaging overthinking and worrying.</p><p>Cognitive behavioral therapy (CBT) is currently a gold standard in psychotherapy. CBT aims to change the way people think and act. It largely involves challenging unhelpful beliefs or attitudes such as overgeneralization — thinking "I always fail at public speaking" when you have had one bad experience in front of an audience, for example — or "catastrophization," i.e., imagining the worst possible outcome to a situation. </p><p>A psychotherapist can teach people how to implement such thought-changing techniques into their lives. Techniques vary depending on their issues and goals.</p>
Solutions Are at Hand<p>Try to find ways of avoiding worrying, rumination and overthinking that make you feel most comfortable.</p><p>Incorporating any routine in your life when you're stressed isn't an easy task, but you can do it! If you feel overwhelmed, you can always seek professional help. </p><p><em>If you are suffering from serious emotional strain or suicidal thoughts, do not hesitate to seek professional help. You can find information on where to find such help, no matter where you live in the world, <a href="https://www.befrienders.org/" target="_blank">at this website.</a></em></p>

On Sunday, New Zealand marked 100 days without community transmission of COVID-19.

Getting Through the Pandemic<p>We have gained a much better understanding of COVID-19 over the past eight months. Without effective control measures, it is likely to continue to spread globally for many months to years, ultimately infecting billions and killing millions. The proportion of infected people who die appears to be <a href="https://www.medrxiv.org/content/10.1101/2020.05.03.20089854v4" target="_blank">slightly below 1%</a>.</p><p>This infection also causes serious <a href="https://www.bmj.com/content/370/bmj.m2815" target="_blank">long-term consequences</a> for some survivors. The largest uncertainties involve <a href="https://www.nature.com/articles/d41586-020-02278-5" target="_blank">immunity to this virus</a>, whether it can develop from exposure to infection or vaccines, and if it is long-lasting. The potential for treatment with antivirals and other therapeutics is also still uncertain.</p><p>This knowledge reinforces the huge benefits of sustaining elimination. We know that if New Zealand were to experience widespread COVID-19 transmission, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3310086/" target="_blank">impact on Māori and Pasifika populations</a> could be catastrophic.</p><p>We have previously described critical measures to get us through this period, including the use of fabric face masks, improving contact tracing with suitable digital tools, applying a science-based approach to border management, and the need for a dedicated national public health agency.</p><p>Maintaining elimination depends on adopting a highly strategic approach to risk management. This approach involves choosing an optimal mix of interventions and using resources in the most efficient way to keep the risk of COVID-19 outbreaks at a consistently low level. Several measures can contribute to this goal over the next few months, while also allowing incremental increases in international travel:</p><ul><li>resurgence planning for a border-control failure and outbreaks of various sizes, with state-of-the-art contact tracing and an upgraded alert level system</li><li>ensuring all New Zealanders own a <a href="https://www.nzma.org.nz/journal-articles/mass-masking-an-alternative-to-a-second-lockdown-in-aotearoa" target="_blank">re-useable fabric face mask</a> with their <a href="https://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=12354409" target="_blank">use built into the alert level system</a></li><li>conducting exercises and simulations to test outbreak management procedures, possibly including "mass masking days" to engage the public in the response</li><li>carefully exploring processes to allow <a href="https://blogs.otago.ac.nz/pubhealthexpert/2020/06/16/preventing-outbreaks-of-covid-19-in-nz-associated-with-air-travel-from-australia-new-modelling-study-of-alternatives-to-quarantine/" target="_blank">quarantine-free travel</a> between jurisdictions free of COVID-19, notably various Pacific Islands, Tasmania and Taiwan (which may require digital tracking of arriving travellers for the first few weeks)</li><li>planning for carefully managed inbound travel by key long-term visitor groups such as tertiary students who would generally still need managed quarantine.</li></ul>
Building Back Better<p>New Zealand cannot change the reality of the global COVID-19 pandemic. But it can leverage possible benefits.</p><p>We should conduct an <a href="https://blogs.otago.ac.nz/pubhealthexpert/2020/06/11/five-key-reasons-why-nz-should-have-an-official-inquiry-into-the-response-to-the-covid-19-pandemic/" target="_blank">official inquiry into the COVID-19 response</a> so we learn everything we possibly can to improve our response capacity for future events.</p><p>We also need to establish a specialized national public health agency to <a href="https://blogs.otago.ac.nz/pubhealthexpert/2017/12/20/the-havelock-north-drinking-water-inquiry-a-wake-up-call-to-rebuild-public-health-in-new-zealand/" target="_blank">manage serious threats to public health</a> and provide critical mass to <a href="https://blogs.otago.ac.nz/pubhealthexpert/2020/02/05/a-preventable-measles-epidemic-lessons-for-reforming-public-health-in-nz/" target="_blank">advance public health generally</a>. Such an agency appears to have been a key factor in the success of Taiwan, which avoided a costly lockdown entirely.</p><p>Business as usual should not be an option for the recovery phase. A recent <a href="https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=12353555" target="_blank">Massey University survey</a> suggests seven out of ten New Zealanders support a green recovery approach.</p><p>New Zealand's elimination of COVID-19 has drawn attention worldwide, with a description just <a href="https://www.nejm.org/doi/full/10.1056/NEJMc2025203" target="_blank">published</a> in the New England Journal of Medicine. We support a rejuvenated World Health Organization that can provide improved global leadership for pandemic prevention and control, including greater use of an elimination approach to combat COVID-19.</p>
