New Report: Sources and Land-Use Relations for PFAS in Pennsylvania Surface Waters
Streams and lakes were sampled in 2019, in cooperation with the Pennsylvania Department of Environmental Protection
USGS Pennsylvania Water Science Center in cooperation with Pennsylvania Department of Environmental Protection (PADEP) released a first-of-its-kind Per- and Polyfluorinated Alkyl Substances (PFAS) dataset.
The USGS PAWSC collaborated with the PADEP and the Susquehanna River Basin Commission to collect 216 samples in a single month in September 2019. A USGS data release has recently been published that includes PFAS & associated quality-control (QC) data from integrated, discrete surface-water samples from 178 PADEP Surface Water Quality Network (WQN) sites and 36 QC samples.
PFAS and site location data include:
- Discrete sample concentrations from raw untreated surface water from WQN sites.
- QC results to evaluate effectiveness of sampling procedures & ensure data quality.
- Passive sampler (time weighted average) PFAS concentration data intended to describe a monthly average of PFAS concentrations at a single site; &
- Station identification numbers, latitude & longitude locations, & watershed characteristics
Total PFAS Concentrations in PADEP Surface Water Quality Network, 2019
In September 2019, USGS led a workshop to ensure standard equipment cleaning and sampling procedures.
