Proven & Effective for PFAS Monitoring

Research Article: The Effect of Heterogeneity on the Distribution and Treatment of PFAS in a Complex Geologic Environment

*Article Quote: “The characterization and monitoring of the site was completed with the aid of a series of multilevel wells and continuous cores. The groundwater was monitored using three CMT Multilevel Systems (Solinst, Canada) including one 3-channel system and two 7-channel systems (Figure 1)…To characterize the groundwater prior to and post-injection, groundwater samples were collected for analyses of various chemical parameters including PFAS, BTEX, major cations [calcium (Ca), magnesium (Mg]) potassium (K), sodium (Na), iron (Fe)], manganese [Mn], and anions [chloride (Cl), nitrate (NO3), and sulfate (SO4)] using low-flow sampling methods (Puls and Barcelona, 1996).”

Research Article: Six pilot-scale studies evaluating the in situ treatment of PFAS in groundwater - Rick McGregor

**Article Quote: "The concentrations of the six PFAS within the groundwater sampled from the monitoring well and CMT within the CAC PRZ were all below the detection limit during the five post injection sampling events including samples collected on Day 549 (Figure 9). These results indicate that the PFAS were being effectively adsorbed by the CAC. Sampling and analysis of the CMT multilevel monitoring well indicated that the six PFAS were below their detection limits throughout the vertical extent of the plume including within the coarse‐grained sand seam".

A facility in Pontypool, Wales, UK was once the location of a plastic forming plant. Over time, chemicals produced through the plastic forming processes were lost into the groundwater beneath the facility, creating a large contaminant plume. Years later it was determined that the plume is migrating off site. In order to intercept…
