Pennsylvania Statewide Surface Water-Quality Monitoring Network - Per- and polyfluoroalkyl Substances Sampling Preparation

Science Center Objects

The Pennsylvania Water Science Center, in cooperation with the Pennsylvania Department of Environmental Protection and in collaboration with the Susquehanna River Basin Commission, met to ensure standard equipment cleaning and sampling procedures are used to collect PFAS for the Water-Quality Monitoring Network. Participants cleaned sampling gear and blanked all gear to ensure proper decontamination was possible prior to the sampling scheduled to occur in September of 2019.

Cleaning sampling equipment in preparation for PFAS sampling

PaWSC led a one-day training, coordinating, and blanking exercise as part of a multi-agency effort to sample for Per- and polyfluoroalkyl substances (PFAS) in streams and lakes around the Commonwealth of Pennsylvania. This training was conducted as part of ongoing USGS cooperation with the Pennsylvania Department of Environmental Protection (PA-DEP) in sampling the Pennsylvania Statewide Surface Water-Quality Monitoring Network (WQN). Representatives from PA-DEP, USGS, and the Susquehanna River Basin Commission attended a one-day sample training and coordination meeting and conducted a round-robin equipment-blanking exercise in preparation for planned sampling of the WQN for PFAS in September of 2019. Staff who collect samples from the WQN were briefed on recent USGS findings related to sampling equipment selection, proper cleaning and decontamination, and modifications of standard USGS sampling protocols. In addition, each agency brought equipment that will be used for sampling, reviewed cleaning procedures, and collected equipment blanks to verify that standard USGS surface-water sampling procedures are appropriate for PFAS sampling. Results of the blanking round-robin will be used to inform sampling procedures planned for statewide WQN PFAS sampling by the three agencies.
