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 Interstate Regulatory Technology Council (ITRC) just published three new fact sheets on Per- and Polyfluoroalkyl Substances (PFAS) along with one updated fact sheet. The four fact sheets address important topics related to PFAS remediation technologies, sample collection, laboratory methods, environmental fate and transport, and more. These four PFAS updates from ITRC are the most current guidance available and will provide environmental professionals with detailed information on PFAS
The presence of PFAS at sites throughout Michigan have prompted the Michigan Department of Environmental Quality (MDEQ) to require Wastewater Treatment Plants (WWTP) with an Industrial Pretreatment Program (IPP) to address this emerging contaminant. In a letter to WWTPs dated February 20, 2018, the MDEQ is requiring several actions be taken to ensure that all IPPs are prohibiting discharges of PFOS and PFOA. By June 20, 2018, the MDEQ is requiring WWTPs with an IPP to complete the following:
Because of their prevalence in industrial manufacturing applications, many of our environmental consulting and industrial clients find themselves requiring wipe sampling guidance for PCBs. Merit Laboratories provides its clients with PCB wipe sampling kits to support field sample collection activities. The Merit PCB wipe kits are typically used for the wipe sampling of machinery, equipment, flooring, and other surfaces within industrial manufacturing facilities.
The Michigan Department of Environmental Quality (MDEQ) has released the final Incremental Sampling Methodology and Applications reference guide. The MDEQ guide can be used by environmental professionals as a technical reference for using incremental sampling method (ISM) techniques to evaluate contaminated land while managing risk and future use. ISM is also known as Multi-Incremental Sampling (MIS), Incremental Composite Sampling (ICS), or Incremental Sampling Methodology (IS).
The DoD Environmental Data Quality Workgroup recently issued a fact sheet on detection and quantitation to assist project managers and data users of laboratory data for DoD projects. The EDQW guidance sheet is geared to assist project manager or other decision-makers that use environmental laboratory data to accomplish one or more of the following tasks for a DoD project:
The term summa canister is trying to go the way of other product names that have become generic titles for their intended purpose, like Kleenex and Band Aids. The term summa canister is used in the environmental industry by many professionals to describe the sampling media used for air sampling prior to laboratory testing. There is, however, inherent risk in believing that summa canister is an acceptable term that defines all air sampling media for TO-15 projects.
The rankings are out and three metals top the chart: arsenic, lead, and mercury. The Agency for Toxic Substances and Disease Registry (ATSDR) has released its 2017 list of substances at EPA-managed contamination sites posing the most significant risk to human health. A total of 275 substances are listed on the entire ATSDR 2017 Substance Priority list. Here are the Top 50 substances listed.
After receiving your analytical data report, do you ever wonder why all of the additional quality assurance-quality control (QA-QC) samples are analyzed and reported? The following definitions will help you better understand the various QA-QC samples commonly reported by Merit Laboratories and what they can mean for your analytical data.
Since the beginning of the EPA's Brownfields program in 1995, more than 27,000 properties have been assessed throughout the country, including more than 1,400 in the last fiscal year. A Brownfield property is one where the redevelopment or reuse of the property may be complicated by the presence of a hazardous substance, pollutant, or contaminant.
