Rapid portable detection technology for wastewater and solidwaste

HJ Science & Technology, Inc. proposes to build and test a rapid field portable instrument capable of performing on-site detection of per- and polyfluoroalkyl substances (PFAS) in wastewater and solid waste.  The automated instrument is designed such that all six per- and polyfluoroalkyl substances in United States Environmental Protection Agency’s proposed National Primary Drinking Water Regulation: perfluorooctanoic acid, perfluorooctanesulfonic acid, perfluorononanoic acid, hexafluoropropylene oxide dimer acid, perfluorohexanesulfonic acid, and perfluorobutanesulfonic acid, in the sample can be measured.  Furthermore, the instrument is compact, lightweight, portable, inexpensive, and easy to use, specifically designed for the on-site detection with ppt-level of detection sensitivity. In Phase I, we established the measurement capability by analyzing both tap water and lake water spiked with known PFAS concentrations.  In Phase II, we will build and test a fully functional field deployable prototype. We will use the prototype to analyze real-life samples. The results will be validated by established laboratory based EPA Method 1633.
