At Least 12 Military Bases Contaminating Water Supply With Toxic PFAS

/in , , /by /The Guardianby Tom Perkins

Dangerous levels of toxic PFAS are contaminating water supplies in areas around at least 12 military bases, new Department of Defense testing has revealed, drawing concern from public health advocates that the DoD is not doing enough to protect the public.

The data released this week by the military shows levels for five kinds of PFAS compounds at what Scott Faber, vice-president of government affairs for Environmental Working Group, characterized as “extremely high” levels, and he said they present a health threat to residents living nearby.

PFAS Water Regulations in California Closer to Becoming Reality

/in , , /by /The National Law Reviewby John Gardella

On September 28, 2021, the state of California (through the Office of Environmental Health Hazard Assessment) held a virtual workshop for proposed Public Health Goals (PHGs) for two types of PFAS – PFOA and PFOS. The release of proposed PHGs is extremely significant for any company situated in California, as PHGs are used to create enforceable drinking water standards and limits for groundwater contamination.

US EPA Recommends Testing Wastewater for PFAS

Some facilities may have to test for the presence of per- and polyfluoroalkyl substances in their wastewater, under a new strategy from the US Environmental Protection Agency. The effort could eventually help reduce the level of environmentally persistent and toxic PFAS in drinking water drawn downstream of such facilities as well as in fish and river sediment.

Well Water Throughout California Contaminated with ‘Forever Chemicals’

In the weeks before the coronavirus began tearing through California, the city of Commerce made an expensive decision: It shut down part of its water supply.

Like nearly 150 other public water systems in California, the small city on the outskirts of Los Angeles had detected “forever chemicals” in its well water.

What Happens When a Rural Area’s Only Well is Contaminated?

In the spring of 2013, Jocelyn Walters moved Nativearth, her family’s small shoe business, into a warehouse in Mariposa Industrial Park that gave them more space to grow.

But there was one quirk of the new space she hadn’t foreseen.

The industrial park, which has only four businesses and isn’t connected to the town’s water system, gets its water from a well on her family’s property on the outskirts of Yosemite National Park. So Walters found herself helping run a water company from a shoe business.

New Study Finds PFOA Is Carcinogenic: What Are the California Proposition 65 Implications?

The National Toxicology Program for the U.S. Department of Health and Human Services recently released a Technical Report that found evidence of carcinogenic activity in laboratory rats exposed to perfluorooctanoic acid. The NTP Technical Report may result in the listing of PFOA under California’s Proposition 65 as a carcinogen. Private toxic tort plaintiffs may also attempt to rely on the Technical Report in PFAS contamination lawsuits.

Water Expert Discusses Slowdown in Federal Regulation of Drinking Water

/in , , /by /Phys.orgby Rob Jordan

It didn’t grab headlines, but the U.S. Environmental Protection Agency’s (EPA) decision last month to back away from regulating a rocket fuel ingredient in drinking water points to a dramatic shift in federal oversight. The decision was followed by a proposal to slow the process for reviewing chemicals under the Toxic Substances Control Act (TSCA) and delayed action on hazardous perfluorochemicals, PFAS and PFOA, that have been found in various water systems.

Creating ‘Forever Chemicals’: A Guide to PFAS Companies (2)

/in , /by /Bloomberg Environment (Arlington, Va.)by Sylvia Carignan

The billion-dollar companies that made and used chemicals now popping up in water supplies around the country are switching to newer alternatives, but they haven’t escaped liabilities for historic environmental contamination.

The chemicals, known as per- and polyfluoroalkyl substances or PFAS, have become ubiquitous in everyday consumer goods as well as in specialized industrial applications. For some of the companies, including 3M Co. and the Chemours Co., liabilities from their PFAS operations have negatively affected the value of their stock.

State Board Establishes New Stricter Standard for PFOA and PFOS

/in , /by /California Water News Daily

The State Water Resources Control Board announced yesterday it will reduce the level of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in drinking water that trigger responses by local water systems. Based on recommendations from the California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment the Board lowered response levels to 10 parts per trillion (ppt) for PFOA and 40 ppt for PFOS. Previously, the response level was 70 ppt for the total concentration of the two contaminants combined.

California County Shuts Down Fifth of Water Wells Over PFAS

/in , , /by /Bloomberg Environmentby Emily C. Dooley

California wants to slash the allowable levels in drinking water for two “forever chemical” compounds, immediately prompting agencies supplying water to 2.5 million residents in Orange County to remove a fifth of their wells from service.

The State Water Resources Control board Thursday said it planned to dramatically lower its response levels for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), though actual drinking water standards are still years away.

The response levels require water suppliers to install treatment, and remove wells from service if they exceed the thresholds. Notifying customers is required if districts plan to keep wells in service without treatment for an extended period.

Orange County oversees the area’s groundwater basin and provides water to 19 agencies, which rely on underground supplies for 77% of deliveries. The remainder comes from the Colorado River and Metropolitan Water District of Southern California, which supplies water to 19 million people in the region.
