As PFAS sampling has become increasingly common, so has the ambiguity of regulations and restrictions associated with conducting these types of events. When customers call to place orders, we’re often asked about the suitability of our equipment for their applications. Since PFAS are used in the production of many types of traditional groundwater monitoring equipment, materials and supplies and can be sources of sample contamination, we’ve outlined answers to commonly asked questions in the table below to help guide you through the process of selecting equipment and field supplies for those applications.
Equipment used in PFAS sampling events must be made from acceptable materials, which include high-density polyethylene (HDPE), polypropylene, silicone, stainless steel, nylon, polyvinyl chloride (PVC), acetate, and cotton. Sampling equipment that contain PFAS-based (fluoropolymers) parts that would be in direct contact with the sample or sampling environment should be avoided. With respect to Eco-Rental Solutions’ inventory of rental equipment and consumables, items that are typically considered acceptable and prohibited are listed below.

- Note: The information in the tables avove is based on information we believe to be commonly acceptable for most PFAS related projects. Each state, client or project may have its own unique requirements. Eco-Rental Solutions makes no claims or guarantees, inferred or otherwise, as to the suitability for any of the above equipment for any given application. We strongly advise customers to consult with their specific project plan documentation and administrators to ensure all equipment used is in compliance with your project’s specific requirements.
