To all of our friends and partners in California impacted by the devastating wildfires, Merit Laboratories is here to support you. When wildfires ravage communities, natural landscape, and places we call home, the impact is major. Lives are interrupted while homes, schools, and businesses are destroyed. Another significant impact of wildfires is environmental contamination.
The U.S. Environmental Protection Agency (EPA) continues to address the growing concerns over PFAS by adding nine new compounds to the Toxics Release Inventory. This move aims to improve transparency and provide better data on the presence and release of these persistent chemicals in the environment.
The analysis of PFAS by EPA 1633A and ASTM D8421 is part of the U.S. EPA’s Methods Update Rule (MUR) Rule 22. The action will promulgate EPA into 40 CFR Part 136. Also part of this action, PFAS method ASTM D8421 is proposed to be codified.
The State of Michigan formally adopted a strict set of requirements regulating PFAS in drinking water. The Michigan EGLE announced the adoption of the new maximum contaminant levels (MCLs), which will go into effect on August 3, 2020. The establishment of enforceable MCLs for PFAS compounds will require compliance with the Safe Drinking Water Act (SDWA). Now they are adopted, the PFAS drinking water MCLs replace the current groundwater cleanup standard of 70 ppt for PFOA and PFOS.
Michigan has some of the highest levels of PFAS in the United States. Throughout Michigan, many of the state’s streams, rivers, lakes, and drinking water have been contaminated by PFAS chemicals. To help mitigate future PFAS contamination, the State of Michigan has approved two new bills. Governor Gretchen Whitmer signed into law Michigan House Bills 4389 and 4390 on July 8 that regulate the use and reporting of PFAS-containing firefighting foam, including aqueous film forming foams (AFFF).
PFAS, the “forever chemicals,” have the ability to migrate into the air, dust, food, soil and water. They are used in many common products like weatherproof clothing, non-stick cookware, and firefighting foam. PFAS are called “forever chemicals” because they are persistent and bioaccumulate. Persistent means they do not break down in the environment and bioaccumulate refers to the process of building up over time in the blood and organs.
The State of New York Department of Health (DOH) postponed a final decision on setting PFAS maximum contaminant levels (MCLs) in drinking water The DOH cancelled a June 4th meeting where it was expected to adopt the recommended MCLs of 10 ppt for PFOA and 10 ppt for PFOS. This is the second time the meeting has been cancelled due to the COVID-19 pandemic. As part of the pending standards, the chemical1,4-dioxane is recommend for MCL of 1 ppb. The governor issued an executive order granting a 90-day extension, so the rulemaking must be completed by August 7.
The number of PFAS-contaminated sites in Illinois continues to grow. Combined with detectable concentrations of PFAS in drinking water far above the federal screening level, state regulatory professionals and legislators are facing the reality that Illinois has a significant PFAS problem. The toxic compounds have been detected in water systems and groundwater throughout the state, including sites in Bloomington, Chicago, Galesburg, Peoria and the Quad Cities area. PFAS has also been detected in the groundwater at Scott Air Force Base, Chanute Air Force Base, Naval Station Great Lakes, and the Rock Island Arsenal.
In a continuing trend, another 19 sites with PFAS contamination have been added to the latest list of Michigan sites. The newest Michigan EGLE PFAS Map Tracker shows that the number of confirmed PFAS contaminated sites has grown to 93, up from 74 in December 2019 and 52 a year ago. The latest list of PFAS contamination includes sites spread across Michigan, throughout both the lower and upper peninsulas, in rural, suburban, and urban areas The EGLE also provides a PFAS map viewer, which provides information on the site name, location and address, description of the site, and a link to site-specific background, data, PFAS contaminants, site history, and recent activities.
The U.S. States Environmental Protection Agency (EPA) is adding 172 per- and polyfluoroalkyl substances (PFAS) to the toxic chemicals list that are subject to reporting in the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act. The U.S. EPA took final rule action on the PFAS additions on May 18, 2020.
Merit Laboratories has expanded the list of analytical methods, compounds, and sample matrices for which it is accredited through the DoD Environmental Laboratory Accreditation Program (DoD ELAP). Through this expansion, the DoD officially revised Merit Laboratories' DoD ELAP testing certification to also now include EPA Method TO-15 for the analysis of air samples. Merit is also analyzed for a comprehensive list of analytical methods for aqueous and solid sample matrices.
With the number of PFAS-contaminated sites growing to over 900 in the United States, the U.S. EPA is facing pressure to establish drinking water standards. These PFAS sites impact the drinking water of nearly 25 million people living in the country. Despite the urgency, the U.S. EPA has extended the due date to receive comments on the preliminary decision related to establishing drinking water standards for two PFAS chemicals, PFOA and PFOS. The new due date for comments is now June 10, 2020.
The U.S. Department of Defense is actively performing assessments of PFAS usage and potential releases at more than 650 military installations throughout the country. The list of installations includes sites in all 50 states, the District of Columbia, Guam, Marshall Islands, Midway Islands, Puerto Rico, and the U.S. Virgin Islands. The military installations being assessed cover a diverse range of DoD facilities
