Federal health officials are assessing risks related to elevated levels of arsenic, barium, manganese and methane in an aquifer that supplies homes in a shale gas production zone in Dimock, Pa.
The Agency for Toxic Substances and Disease Registry is following up on an U.S. EPA study that analyzed the water of 64 homes near drilling operations in the Marcellus Shale in the rural community just south of the border with New York State. After six months of testing, the U.S. EPA concluded last month that levels of pollution in five of the wells—roughly 8 percent—were high enough to pose health risks, but those risks were mitigated by treatment systems installed in or planned for the homes.
The U.S. EPA investigation was prompted by an ATSDR analysis of previous water tests in December, 2011. The ATSDR, acting on concerns by residents, evaluated records of previous samples collected by both Cabot Oil & Gas and the Pennsylvania Department of Environmental Protection. Officials found evidence of elevated levels of various solvents, metals, and glycols that posed “a possible chronic public health threat based on prolonged use of the water” in “at least some” of the Dimock wells.
According to the report, ATSDR Record of Activity/Technical Assist UJD #: IBD7:
Agency officials visited the Dimock homes along Carter Road and State Route 3023 on Nov. 10, 2011 and were provided a large amount of well data. Based on the home visits and preliminary review of data, EPA and ATSDR raised the following concerns: the reliability of methane removal systems; the presence of other contaminants besides methane (metals, volatile organics and non-naturally occurring organics) for which the well treatment systems are not designed or in place to address; and homes/wells in Dimock that may have never been tested and may be contaminated. The multiple sampling efforts at this site to date were conducted by PADEP and private contractors not affiliated with EPA.
In response to the concerns, the U.S. EPA subsequently tested wells in the area between January and June. In July, the EPA press office issued a release that stated “no further action” was needed by the EPA. But the release failed to mention that the EPA results would be factored into a broader health study by the ATSDR. Accordingly, the EPA results were widely characterized by news outlets as resolution to pollution questions that have nagged the small town overlying one of the most lucrative production zones for the Marcellus shale.
The ongoing ATSDR investigation and follow-up -- cited in the Record of Activity/Technical Assist – were confirmed by Bernadette Burden, a spokeswoman for the ATSDR. According to Burden, the agency is pursuing “a fairly comprehensive review” of the Dimock water case that takes into account the EPA tests, as well as previous tests by Cabot contractors and the DEP. The ATSDR -- a branch of the Centers of Disease Control and Prevention -- will account for risks of long-term exposures to the water through showering, drinking, bathing and washing, as well as risks that might be compounded when people are exposed to multiple toxicants. There is no time frame for the completion of the report, she said.
According to the December 2011 “Record of Activity/Technical Assist”:
A full public health evaluation should be conducted on the data from the site area. Because many of these compounds (e.g. metals) affect the same organ systems, ATSDR recommends evaluating the mixture for public health impacts using computational techniques or other suitable methods to evaluate the potential for synergistic actions: The cumulative concentration of all dissolved combustible gases should be considered to protect against the buildup of explosive atmospheres in all wells in the area.
The contaminants found by the U.S. EPA—arsenic, barium, manganese and methane—occur naturally in the ground. They are also associated with drilling operations, which can exacerbate existing problems or introduce new ones. In the five cases where the levels were high, according to the EPA press release, the residents have or will have treatment systems to reduce chemical concentrations to levels acceptable for potable water.
Dimock has been the focal point of a national controversy over the impacts and risks associated with shale gas development and high volume hydraulic fracturing. The process, commonly known as fracking, involves injecting bedrock with millions of gallons of chemical solution to stimulate the flow of natural gas. While fracking has often been implicated when things go wrong, the migration of methane and other chemicals in the ground into aquifers can be caused by drilling in the absence of fracking. Barium, one of the problem chemicals found in Dimock, is a common constituent of drilling “mud” – a viscous solution used to lubricate the drill bit and float cuttings to the surface.
The Dimock conflict began on Jan. 1, 2009, with the explosion of a well that supplied water to the home of Norma Fiorentino, a plumber’s widow and great grandmother. A subsequent investigation by the Pennsylvania Department of Environmental Projection (DEP) found that methane was seeping from nearby drilling operations into an aquifer that supplied Norma’s well and others along the Carter Road area. Cabot contested the findings after the DEP, under Governor Ed Rendall’s administration, determined that the aquifer was permanently damaged from methane migrating from the bores of nearby gas wells. The DEP ordered Cabot to build an $11 million water pipeline to supply affected homes. That order was lifted shortly after Tom Corbett won the gubernatorial election in November 2011.
Last month, Cabot reported that it had reached terms for a settlement with 32 of 36 Dimock families that were suing the company for water pollution. Terms of the deal were not disclosed. Not all the plaintiffs accepted the deal, and some are continuing to pursue the case.
Note: I asked EPA officials the following question through spokeswoman Terri-A White. White told me to expect a reply soon. I will update this report accordingly.
EPA’s sampling of Dimock wells shows hazardous levels of methane in six instances.

What steps have been taken to correct this?
ATSDR Record of Activity/Technical Assist (UJD #: IBD7 Date: 12/28/2011) advises the EPA that “Additional characterization of the groundwater quality and a thorough review of any changes in concentration over time are indicated. “
Has this been done?
In the same document, the ATSDR has also recommended that “A full public health evaluation should be conducted on the data from the site area” and “evaluating the mixture for public health impacts using computational techniques or other suitable methods to evaluate the potential for synergistic actions” and “The cumulative concentration of all dissolved combustible gases should be considered to protect against the buildup of explosive atmospheres in all wells in the area. “

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>
