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.
Merit Laboratories is now certified for PFAS through the DoD Environmental Laboratory Accreditation Program (DoD ELAP). As a result, Merit Laboratories has expanded the list of analytical methods, compounds, and sample matrices for which it is accredited through the DoD ELAP, including the DoD’s PFAS method
In what surely will impact environmental regulatory programs across the United States, the EPA is actively prioritizing PFAS in the environment and has taken two recent actions to continue to address contamination. The EPA has issued a memo detailing an interim National Pollutant Discharge Elimination (NPDES) permitting strategy for PFAS.
To support PFAS investigations, monitoring, and scientific studies, Merit Laboratories has expanded its list of available PFAS compounds for environmental laboratory testing. Merit now provides analytical testing for 46 PFAS compounds by LC/MS/MS with isotopic dilution. Results were validated by the laboratory in an October 2020 Method Detection Limit (MDL) study.
The first-ever Great Lakes PFAS Summit has gone virtual. The event will bring together scientists, government officials, regulators, academic researchers, industry, and community organizations on all topics PFAS. The virtual summit is now scheduled for a five-day event, set for October 26th - 30th, 2020.
Merit Laboratories has added laboratory accreditation through the Pennsylvania Department of Environmental Protection (DEP). The list of accredited analytical parameters includes metals, organic, and inorganic test methods. The Pennsylvania DEP is a NELAP recognized accreditation body. The Pennsylvania laboratory accreditation is based upon compliance with NELAP and Pennsylvania code, 25 Pa Code Chapter 252.
Significant levels of PFAS have been detected in the blood of Michigan residents in one state county. The results are summarized in the initial report just released by the Michigan Department of Health and Human Services (MDHHS) as part of the PFAS Exposure Study Assessment. This exposure assessment measured serum concentrations of 30 PFAS among a sample of residents in the northern part of Kent County area that previously had validated detectable PFAS levels in their private drinking water.
Merit Laboratories offers several analytical options for PFAS. Analytical methods performed by Merit Laboratories include EPA 533, EPA 537 Rev. 1.1, EPA 537.1 ASTM D7979-19 with Isotopic Dilution, and ASTM D7968-17. The following summary will help guide you through selecting the most appropriate PFAS method for your project. EPA 537 Rev. 1.1: This is a drinking water method for 14 PFAS compounds using Solid Phase Extraction and Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS).
Merit Laboratories has become the first laboratory to be certified by the State of Michigan for PFAS testing in drinking water. Merit’s certification for PFAS testing, using EPA Method 537.1, is through the Michigan Department of Environment , Great Lakes & Energy (EGLE).
There are many locations in the state of Michigan where PFAS pollution has become widespread and where warnings been put in place such as; ’Do Not Eat’ fish advisories, and ‘No Swim Zones’. For example, residents living near the Wurtsmith Air Force Base, have health advisories in place warning people not to consume fish, deer and other wildlife in several areas, and avoid toxic surface water foam. The federal government, however, has yet to provide a universal, nationwide standard for PFAS.
