A DEEPER DIVE INTO THE PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) PROBLEM
Of the thousands of PFAS compounds, the U.S. EPA has published Health Advisory (HA) levels of
70 parts per trillion (ppt) for two compounds: perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). As of March 2020, 23 states have adopted drinking-water standard values for some PFAS compounds; a few of these states have adopted enforceable water quality standards at levels lower than the EPA HA levels. The EPA is making progress toward establishing maximum contaminant levels (MCLs), having passed a positive regulatory determination for PFOA and PFOS in February 2020.
Trihydro offers presentations on multiple aspects of the PFAS Problem, including the following:
- PFAS overview: uses, environmental sources, and site management considerations
- Site characterization and remediation
- Data interpretation, toxicology, and risk assessment
- Aqueous film forming foam (AFFF) management
- Presentations may be tailored to focus on aspects specific to certain site type (e.g., firefighting training, hydrocarbon handling facilities, landfills, wastewater treatment).
Trihydro’s PFAS presentations are developed in accordance with our philosophy on management of sites potentially impacted with PFAS: current guidance must be balanced with insights into where things are headed. Trihydro is actively involved in industry trade groups including Interstate Technology Regulatory County (ITRC), National Ground Water Association (NGWA), and a PFAS coalition organized by a law firm to keep current on regulatory developments.
