Time-Integrated Results with Reduction of Investigation-Derived Waste

Battelle’s innovative, patent-pending solution is designed specifically for PFAS and addresses several challenges in sampling groundwater. Traditional sampling methods result in large volumes of investigation-derived waste (IDW), which can be difficult and expensive to dispose of and can lead to stockpiled waste. PFAS Insight® passive sampling technology relieves these concerns.

How It Works


The PFAS Insight® passive sampler consists of a polymeric sorbent suitable for adsorbing neutral and ionic PFAS from a variety of aquatic environments. The passive samplers are delivered to the study site assembled and ready to deploy. No special training is required for installation and retrieval. After being deployed at the site for about one month, the samplers are shipped to our PFAS-accredited laboratory, where sorbent will be extracted and analyzed, and the results will be converted into equilibrium water concentrations using laboratory-derived partition coefficients.
