Represnetative Brian Baldridge proposed a bill that will prohibit Dayton, Ohio fire departments from training with PFAS infused foam. The dangerous chemical has been found to have contaminated an aquifer underneath the fire training center that sources the city’s drinking water. The bill still allows for the use of the foam in necessary fire fighting circumstances; however, departments must find an alternative training source by January 1, 2020. Read More.

The Water Infrastructure Funding Transfer Act would give states facing public health crises from lead in drinking water the flexibility to make a one-time transfer, up to $100 million, of the federal funds in their Clean Water State Revolving Fund to their Drinking Water State Revolving Fund for projects that will remove lead from drinking water.

A number of houses surrounding the Consumer Energy J.H. Campbell Coal Plant in West Olive, Michigan found high levels of radium, arsenic, and lead in the local water supply. It is currently unclear if the contamination is a result of groundwater leakage from the plant’s coal ash pond. Further testing is needed to determine the exact source of contamination and how it entered into the groundwater supply. Read More.
The water samples drawn Aug. 8 at Crete-Monee Middle School found numerous school drinking fountains that tested well above the EPA action level, including one that was 90 times above the level on first draw and 30 times above the level after a 30-second flush, according to district-supplied data.

Wisconsin Gov. Tony Evers has signed an executive order to curb contamination from chemicals in firefighting foam, non-stick cookware and fast-food wrappers, his office announced Friday.
The state DNR will have to create a council to develop a PFAS action plan for the state and evaluate the risk PFAS pose to public health. The agency already has a PFAS technical advisory group that examines the chemicals’ impact on the state but it doesn’t have an appointed membership. Anyone can attend the group’s meetings.
The DNR also must develop regulatory standards for the chemicals. Evers’ administration in June proposed a new PFAS enforcement standard of 20 parts per trillion, far below the 70 parts per trillion federal standard. The DNR is currently gathering public input on the standards. DNR spokeswoman Sarah Hoye said the executive order allows the department to propose rules implementing the new standards. Read more.
Some Pittsboro, North Carolina residents have been suspicious of their water since testing in 2017 showed that there were elevated levels of PFAs in Cape Fear River, their main water source. The toxins come from the Chemours Fayetteville Works chemical plant, located upriver of Pittsboro.
According to Pittsboro’s mayor, very few residents are aware that their water may be contaminated with PFAS. While the levels found weren’t technically above the legal limits, research suggests that there isn’t a safe level of PFAS contamination in water because the chemical remains in people’s systems for extended periods of time.
Duke University will be conducting a study on the impacts of PFAS in the bloodstream on human health, and will take blood samples of atleast 30 Pittsboro residents in the coming year. <Read more>
This is the question that journalist Jim Daley raised recently in an article published in Scientific American. According to the article, the U.S. Environmental Protection Agency (EPA) is substantially changing the program that evaluates the toxicity of chemicals by shifting staff and program emphasis from the Integrated Risk Information System (IRIS) to duties related to implementation of the Toxic Substances Control Act (TSCA). Daley writes that “Former EPA officials contend that the shake-up takes chemical assessments out of the hands of career scientists, potentially to the detriment of public health.”
As evidence of this shift, Daley writes that that the agency has reduced the number of its ongoing chemical toxicity assessments from twenty to three.
The IRIS Program began in 1985 to support EPA’s mission to protect human health and the environment by identifying and characterizing the health hazards of chemicals found in the environment. The IRIS program has become the most respected scientific program in the agency. Its health assessments are the backbone of EPA risk analysis work and is the preferred source of toxicity information used by EPA to determine public health risks. It is also an important source of toxicity information used by state and local health agencies, other federal agencies, and international health organizations.
The TSCA program on the other has a much narrower focus which is primarily on reporting, record-keeping and testing requirements, and restrictions relating to chemical substances and/or mixtures, according to EPA’s website. Certain substances are not covered by TSCA including food, drugs, cosmetics and pesticides. While the 2016 amendment to TSCA greatly improved this regulation, it did not address its narrow focus. This shift began with the leadership of Andrew Wheeler who took over for a beleaguered Scott Pruitt as administrator of EPA in July 2018.
One EPA official who declined to be identified was quoted in the Daley article saying that IRIS and TSCA are “very different” in their approaches to evaluating the public health risks posed by exposure to chemicals. “One could make the argument that this is political interference, in that high-level people are saying which methodology we should be using to assess the safety of a chemical. “And the policy’s pretty clear that they’re not supposed to do that.”
Bernard Goldstein, Professor Emeritus at the University of Pittsburgh School of Public Health, who served as EPA Assistant Administrator of the Office of Research and Development (ORD) from 1983 to 1985, summed it up this way in the Daley article, “I really see this as part of a restructuring of EPA in such a way that science will have very little to do with what EPA is basing its regulation on, and that we will end up with much weaker regulations in terms of protecting public health. “It’s troubling, in large part because it’s very consistent with an overall approach – a very astute approach – to take out the inconvenient facts.” Also cited in the same article was a comment by Thomas Burke from the Johns Hopkins Bloomberg School of Public Health, a former EPA lead scientist adviser and Deputy Administrator of ORD from 2015 to 2017, “’any reduction’ of the number of IRIS chemical assessments ‘is a loss for public health and, unfortunately, puts populations who are exposed at risk.’”

In August 2018, a dive group found barrels containing the two specific toxic chemicals required to make Agent Orange at the bottom of Wallowa Lake, Digital Journal reports. One of these chemicals is known to be contaminated with dioxins, which were used in Oregon forests as a herbicide until higher rates of miscarriages were reported in 1979. Residents were alarmed, not only because the lake is treasured by the community but also because it provides drinking water to the nearby town Joseph. However, Oregon DEQ still has not pulled these barrels out of the lake. <Read more>

While drinking water in the United States is some of the safest in the world, that doesn’t mean that everyone should be drinking the water that comes out of their tap. Water scientist Joan Rose reports in the Great Lakes Echo that 43 states have toxic fluoride contamination in their water (PFAS), and many agricultural communities face arsenic and nitrate contamination from agricultural runoff.
Every single person on the planet needs to drink water in order to survive, and for many families, buying bottled water becomes an unfair financial burden. Under the Safe Water Drinking Act (SDWA), the EPA has been able to execute a water quality management program that keeps most of our tap water safe to drink. However, some communities are slipping through the cracks and many citizens are unwittingly drinking contaminated water. <Read more>[/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]

In the small town of O’Brien, Texas, residents drank water that violated drinking water quality standards for months before one resident found out and altered his community. Facing financial stress, the city had switched from a treated reservoir to a groundwater source with violatingly high levels of nitrates to provide drinking water for its residents.
Nitrate pollution usually comes from fertilizers, as in agricultural towns like O’Brien, and can cause methemoglobinemia, or “blue baby” disease in infants. Nitrate levels in O’Brien schools were found to be 40% above EPA standards. Upon hearing the news, many residents switched to drinking bottled water or purchased individual water filters, but not all were financially able to.
O’Brien is just one example of residents suffering from public water quality violations, but they are not alone. In fact, millions of Americans consume unsafe public drinking water everyday.
Is US Drinking Water Safe?
According to the Center for Disease Control and Prevention (CDC), the US has “one of the safest public drinking water supplies in the world”. Recent reports, however, have challenged that statement. In March, EPA’s Administrator Andrew Wheeler assured that 92% of public water in the US meets EPA standards.
Given that 90% of Americans, or 300 million people, rely on drinking water from a public source, the 8% that doesn’t currently meet EPA standards indicates that over 26 million Americans consume unsafe water daily. Additionally, while the EPA sets legal limits for over 90 drinking water contaminants, ensuring that these limits are not breached is dependent on proper funding and oversight. Based on the 22% decrease between 2009 and 2014 in funding for public water distribution by state and local governments nationwide, it is possible that more than 8% of the nation’s water is unsafe.
Lead Violations
While the CDC has determined that there is no safe blood level of lead for children, the EPA lead rule determines action must be taken if 10% or more of taps sampled have a lead level of 15 ppb or greater. Recently, this rule has come under scrutiny as many companies find ways around the regulation, by selectively testing certain taps, “pre-flushing” or sampling slowly to reduce samples’ lead concentrations.
Additionally, in 2016, CNN found 5,300 US water systems, serving more than 18 million people, to be in violation of this rule. When the lead rule was first implemented by EPA in 1991, 10 million lead lines served public water nationwide. While this number has decreased to 6.1 million lead lines, there are still 15-22 million Americans served by lead lines, predominantly in the Midwest.
Bacterial Violations
Of the 10,000 public systems violating EPA drinking water standards in 2015, 72% of them were bacteria violations. Bacterial drinking water illness outbreaks have been rising since 2000, with 42 outbreaks between 2013-2014, causing over 1,000 cases of illness. Such violations often occur from contamination of water supplies by animal manure from agricultural operations or sewage, causing 16 million cases of acute gastrointestinal illness annually.
Disparate Impact
Violations of water quality are not experienced equally across the nation, and instead they disparately impact communities of color and low socioeconomic status. Research has determined that the prevalence of nitrates and pesticides in drinking water supplies in the San Joaquin Valley, California’s agricultural powerhouse, is significantly higher in Latinx and low-income communities. After the well-publicized water crisis in Flint, Michigan, children residing in socioeconomically disadvantaged neighborhoods were found to have greater elevation of blood lead levels when compared to their peers.
