PFAS Sampling

Since 1978 Geotech has been at the leading edge of manufacturing technology used to collect environmental samples that comply with EPA Clean Water Act initiatives. The emerging contaminates per-and polyfluoroalkyl substances (PFAS) now pose widespread contamination concerns, environmental risk, human health implications, and challenges with sampling and mitigation. With a growing need to bring scientific solutions to government and private sectors, Geotech began removing compounds associated with PFAS sources from common environmental sampling products.

Laboratory Certified

Geotech is also committed to maintaining unmatched product quality while guarding against false positives from PFAS contamination. Geotech submitted several product samples to an independent certified laboratory to test for 26 PFAS compounds, including PFOS and PFOA. The samples were analyzed per EPA 537 method modified and the certificate of analysis resulted in non-detect (ND) of all samples tested. The research concluded that Geotech field sampling and remediation equipment is an unlikely source of contamination for Perfluoroalkyl and Polyfluoroalkyl substances.

PFAS Mitigation

An effective pump and treat system commonly consists of either a pneumatic or electric pump and granular activated carbon (GAC). This combination is typically the least-expensive PFAS treatment option.

FEBRUARY 2020 - EPA PFAS ACTION PLAN PROGRAM UPDATE
EPA is releasing the PFAS Action Plan: The plan will address groundwater cleanup guidance by proposing a positive regulatory determination for both PFOA and PFOS. The EPA has made progress under every aspect of the Action Plan. The actions the EPA has taken reflect the comprehensive and coordinated approach… read more

PFAS and GenX
Per-and polyfluoroalkyl substances (PFAS) refer to a group of synthetic compounds containing thousands of chemicals formed from fluorine. PFOA and PFOS are the most widely produced and studied chemicals due to their extensive use in is a variety of industries, such as aerospace, automotive, textiles, and firefighting foams… read more
