PFAS Response - Per- and polyfluoroalkyl substances (PFAS), also known as perfluorinated chemicals (PFCs), are a large group of more than 3000 man-made fluorinated organic chemicals that have been used since the 1950s in firefighting foams, oil and water repellent products, and surfactants. PFAS can be released to the environment by manufacture and use of items that have PFAS in them.

In fact, wastewater treatment plant effluent is a major contributor of PFAS in surface water. Understanding the role that treatment plants play in managing this hazard can help us better understand the affects of PFAS on human health and the environment. What Are PFAS? Per- and Polyfluoroalkyl Substances (PFAS) are a group of manmade chemicals that include PFOA, PFOS, GenX and many …

With this awareness, communities began testing and seeking PFAS treatment options. In 2016, the EPA established a health advisory level of 70 parts per trillion combined for the main drinking water PFAS chemicals, PFOS (perfluorooctane sulfonate) and PFOA (perfluorooctanoic acid). With drinking water PFAS measured in the parts per trillion ...

Last year, it also launched the nation’s largest water treatment pilot program for PFAS, through which it tests various methods of filtering PFAS chemicals out of drinking water, specific to each retail agency in its service area. Those efforts proved prescient when in early 2020, the State of California lowered the acceptable levels for PFAS, prompting the closure of groundwater wells in ...

Vor 11 Stunden· $2.4 million for the development of standards to limit industrial discharges of PFAS to surface waters and wastewater treatment plants. $1.5 million to set a national drinking water standard for PFAS in drinking water. $1.4 million for reporting of PFAS releases into the air and water under the Toxic Release Inventory. Additional funding to support the EPA’s PFAS research and the U.S ...
Chat OnlineTreating PFAS contaminated water before discharge to aquatic receiving sources will reduce its accumulation in water systems. Currently industrialized methods for removing PFAS from contaminated waters are based on (1) physical adsorption technologies, such as granular activated carbon (GAC) and ion-exchange (IX) resins; and (2) high-pressure membrane filtrations, such as nanofiltration (NF ...

Vor 12 Stunden· Enforcement will be done through annual tests on water treatment systems. Households that obtain their water from private wells will not be impacted by the rules. The new standards will also result in 42 new sites being added into EGLE’s list of PFAS contamination investigations. The action was hailed by environmental groups, many of which have been long urging …

23.07.2020· “All three of Clermont County’s water treatment plants were sampled as part of Ohio’s Statewide PFAS Action Plan for Drinking Water and there was no detection of PFAS from the raw or finished water at any of our treatment facilities.” The plan calls for Ohio EPA to gather data from public water systems statewide to determine if PFAS are present in drinking water. The water system was ...

Two treatment methods have been proven successful in treating PFAS, and both have their advantages and disadvantages, depending on site characteristics. Additionally, studies of membrane technologies are showing positive results. Granular Activated Carbon (GAC) GAC is the most common treatment method, used for more than 15 years. One of the major advantages to using GAC is ...
