TRC’s per‐ and polyfluoroalkyl substances (PFAS) experts published an article that investigates the potential for cross-contamination from a number of commonly used products during sampling.

Abstract:

Can PFAS be transferred from the common field and other commercial products during sampling? Special handling and care are always advised when collecting samples for PFAS analysis to avoid sample contamination. The potential presence of PFAS in common consumer products and in equipment typically used to collect environmental samples, coupled with the need for very low reporting limits heightens this concern.

In this paper, the authors investigate what the potential for crosscontamination is from a number of commonly used products, with the emphasis on evaluating what the possible worst‐case scenario for cross‐contamination could be. Polytetrafluoroethylene (PTFE), low‐density polyethylene (LDPE), and high‐density polyethylene (HDPE) tubing, pump bladders, and other materials are evaluated along with associated products such as aluminum foil and plastic storage bags. In the experimental design of this study, the products themselves are not analyzed directly for PFAS. Rather, a series of experiments are performed utilizing a leaching procedure to evaluate the potential for cross-contamination and false‐positive environmental sampling results. This study was performed in a series of experimental batches over the course of a 1‐year period. Analytical results are presented along with experimental observations and recommendations.

Support an Integrated EHS/ESG Management System

juin 10, 2022

While a Phase I Environmental Site Assessment (ESA) is a common method for identifying environmental liabilities during transactional due diligence, the ASTM International standard for Phase I ESAs (E1527-13, with proposed E1527-21 awaiting adoption) omits regulatory compliance from its scope. For properties containing operations that may be applicable to environmental compliance regulations, performing a limited environmental regulatory review can identify potential deficiencies with the environmental management of the facility. A limited environmental compliance review typically evaluates the presence of material findings that may exist in a facility’s management of its environmental compliance requirements. Material findings are defined as a condition of non-compliance that could necessitate expenditures, not including attorney fees or regulatory agency penalties, in excess of a specified dollar amount or materiality threshold. The materiality threshold is based on the client’s risk tolerance and is often in the range of $50,000. However, this amount is arbitrary and can be revised as appropriate. Non-material deficiencies, those identified below the materiality threshold, would still require action but are within the client’s risk tolerance.
