Tap Water Safety: There’s Good News and Bad News
Sometimes our drinking water systems experience dangerous failures, such as the Flint lead poisoning disaster that made major news beginning in 2014. But outside those headline grabbing crises, how safe is our drinking.
The nonprofit Environmental Working Group wants to help you answer that question. It has collected all the water-quality information that utilities in the U.S. submit to their state environmental or public health agencies. That information has been compiled into a newly updated database that allows residents to check the safety of tap water in their community and then learn what kind of actions they can take if their water contains contaminants. In many cases it's as simple as adding a filter.

But there are some bigger issues lurking that could affect our water quality far into the future. For starters, regulations and standards aren't keeping up with science, and there are many unregulated contaminants that could pose a health threat. There are also big data gaps on water quality for some people living in more rural areas.
We spoke with Environmental Working Group senior scientist Tasha Stoiber about what we know and don't know about the safety of our drinking water — and what steps communities can take protect themselves.
Overall, how safe is drinking water for most people in the United States?
I think a lot of people think that because water is tested in the U.S. and it comes out of the tap, it must be completely fine. Probably most of the time it might be, but there still could be pollutants in there that you should be concerned about.
Many of the federal standards that we do have are not protective enough of health. There hasn't been a new drinking-water regulation passed in nearly 20 years. We still don't have regulations for about half of the detected contaminants and the regulations — or the maximum contaminant level — that we do have for a lot of the contaminants are outdated and based on old science.
For example, the maximum contaminant level for nitrate was set based on a standard back in 1962. Science has come a long way since then. [Editor's note: The U.S. sets the legal limit for nitrates at 10 milligrams per liter, while some recent research suggests that levels above 5 milligrams increase the risk for certain cancers and birth defects.]
So even though the drinking water is legal for them to serve it to us, it might still be associated with some potential risks for health, especially those who are more susceptible like children or pregnant women.
What should people do? We can’t just switch our tap water to another company.
That's one of the reasons that we put this tap-water database out. We'd love to start a national conversation about drinking-water quality and how it can be improved. We want people to be informed and we want them to understand more about their water.
We recommend doing your research, finding out what's in your water and filtering your tap water to eliminate as much of that health risk as you can.
We want consumers to be empowered to ask their water utility or their elected officials about their water. Why are these contaminants in my water? What are you doing to remove them? What treatment technology is available in my community and how are we creating funding to improve water in our area?
There are about 44 million people in the United States who rely on private wells for drinking water. What do we know about the safety of their water?
That's a big data gap — we don't have a lot of information on private wells.
There are actually no federal requirements for private well testing. Sometimes depending on the state that you're in there could be requirements to get a well tested if there's a real-estate transaction.
But usually in most states it falls on the homeowner to get their well tested. And it just doesn't happen that much. One issue might be that people have a false sense of security if they're drinking the water and it seems fine. But the other issue is that testing also costs money. So unless there's some kind of reason to test for it, most people don't do it.
And when it comes to public water systems, the most vulnerable are often water systems that serve smaller or rural communities — especially those that rely on just one water source, such as a single well. If you're a larger system with a number of different sources and one gets contaminated, you can shut it off and not have capacity issues. Large systems usually have the resources and scale of economy to deal with problems that come up. But for the smaller systems, that's going to be a little bit more difficult.
Which contaminants are you most concerned with right now?
Something that you've likely been hearing about in the news is a group of highly toxic fluorinated chemicals called perfluoroalkyl substances (PFAS) [that have been linked to cancer and harm to reproductive and immune systems]. We don't have any enforceable national regulations for them and they are pervasive. Some communities may test for them. New Jersey, for example, is setting its own levels for certain PFAS chemicals. [California has also just mandated testing in high-risk areas.] It is really one of the most notorious chemical groups that needs to be addressed.
[Cancer-causing] hexavalent chromium is another one where there's no federal standard specifically. California did attempt a state maximum contaminant level, but there were issues [after a legal challenge from a taxpayers group] and they had to go back to the drawing board.
It can become a hugely political issue in dealing with any of these things. Communities shouldn't have to pay for the pollution in their drinking water if a specific industry caused it, but often it ultimately falls on the ratepayers if industry hasn't taken responsibility.
So we want people to have all of the information available to them. You do get a consumer confidence report every year [from your water utility], but that might not include information on all of the different contaminants that were tested.
But all of that information is in our database. And it breaks down all of the health-associated risks with each of the contaminants and what our gold standard health limits would be for each of those.
Most of our health standards are based California's Office of Environmental Health Hazard Assessment and their public health goals. Those are based purely on protection of health and no other economic or political factors.
Are you worried that more bad press about tap water will lead people to drink bottled water instead?
Bottled water is no safer than tap water. It can also contain contaminants, as well as microplastics. What's more, companies don't have to disclose bottled-water testing results to the public, so you often don't know what you're getting.
That's why we don't consider bottled water a long-term solution, and recommend it only be used in extreme cases — such as after storms or earthquakes.
I do think it's easy to look at the information and to panic or to even get desensitized. Drinking water quality is going to vary depending on where you live. In California, or some other areas where there is longstanding legacy pollution, there are situations where there is an acute risk with water quality and you shouldn't be drinking what's out of the tap.
But that's an extreme situation. For most people there's not going to be that need to panic immediately. We're talking about the risk of drinking this water over your lifetime.

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>

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>
