QED Environmental Systems’ groundwater sampling pump tested PFC-free

Graco subsidiary QED Environmental Systems Inc reports that its Sample Pro® Portable Pump, developed specifically to deliver low-flow sampling to sites requiring portable pumps, has been tested to be free of PFC, a groundwater contaminant. 

Sample analysis by an independent laboratory showed no detections for 24 different perfluorinated compounds at detection limits much lower than the US EPA Health Advisory of 70 nanograms per liter for perfluorinated compounds under advisory.

Perfluorinated compounds (also called PFCs, perfluorinated alkylated substances or PFAS) have been identified as an emerging contaminant in groundwater. Site owners and environmental consultants have been tasked with sampling for the presence of these chemicals at extremely low concentration levels, down to parts per trillion (or nanograms per liter).

The Sample Pro Portable Pump is said to combine the sample accuracy and high reliability of a bladder pump in an easy-to-use package. Its twist-open design makes it easy to change the disposable bladder in seconds. The pump runs cool, can run dry without damage, and can be operated using any of QED’s Micro Purge® controller options: a 12-volt integral compressor, a Honda® motor-powered gasoline-driven compressor, an external compressed air cylinder, or a lightweight backpack with integral CO2 cylinder.
