Eurofins Environment Testing Lancaster Laboratory has developed this webinar to help inform Maryland based consultants/engineers, industrial clients, and government agencies operating wastewater treatment plants who manage biosolids, of the requirements for PFAS testing starting in 2025.
Over the past two decades, the USEPA and State regulatory agencies have worked to develop standards for addressing PFAS contamination in the environment. These standards depend upon available toxicity information and the rule-making process can be lengthy.
The long awaited PFAS drinking water regulation has been developed by the United State Environmental Protection Agency (EPA) and will be effective on June 25, 2024. This new rule sets the nationwide enforceable MCLs for five individual PFAS, including PFOA, PFOS, PFNA, PFHxS, and HFPO-DA (known as “GenX chemicals”).
Join Eurofins Environment Testing and Barr Engineering Co. for an in-depth webinar delving into the intricacies of the Environmental Protection Agency's (EPA) only available test methods for measuring per- and polyfluoroalkyl substances (PFAS) in air emissions from stationary sources: Other Test Method-45 (OTM-45) and the new OTM-50.
Per-and Polyfluoroalkyl Substances (PFAS) have emerged as a concern at many sites as they are persistent, bioaccumulative, and have demonstrated toxicity in laboratory animals, therefore it is a critical need to understand their migration pathways and bioavailability for proper delineation and risk characterization.
The views on PFAS have changed dramatically over the last 15-20 years. What was once viewed as a “better-living-through-chemistry” dogma by incorporating PFAS into many industrial aspects and consumer goods, has flipped to reckoning and remediation as the toxicological data continues to stack up.
When we look at destruction options for PFAS, we are often looking at some form of thermal remediation or incineration. With these processes we must monitor the destruction efficiency of the target compounds and monitor the stack gas for what is being emitted into the ambient air. We also need to be mindful of what is occurring at facilities where PFAS chemicals are part of the manufacturing process.
Current analytical methodologies measure a discrete list of up to approximately 80 PFAS compounds. Many additional PFAS are not determined as discrete compounds by existing commercial methods, therefore we may be underestimating the PFAS mass present in the environment. As the investigation of sites contaminated with PFAS matures, there is a growing interest in determining the contributions of different sources, to the overall contamination.
The chemistry and analysis of PFAS is unique and challenging, and there is no consensus best method for all target analytes or matrices. The USEPA published Method 537 in 2008 with an update in 2018. This method is applied to 18 PFAS compounds in drinking water matrices only.
Many sites have been required to add the analysis of PFAS to their ground water sampling plans. Military bases, airports, landfills and manufacturing facilities are sites where PFAS contamination may be present due to the use of PFAS in activities such as fire suppression, waste disposal, or industrial processes.
