USGS Research on MIP-ES Methods for PFAS Sensing in Environmental Water

The U.S. Geological Survey is seeking a research partner to improve PFAS sensing in complex environmental water samples. - Government buyer: U.S. Department of the Interior, U.S. Geological Survey (USGS); the opportunity is for a partner in the Northern Great Plains Cooperative Ecosystem Studies Unit (CESU). - Requested work: Develop and evaluate a quantitative ratiometric method to reduce solution-chemistry interference in molecularly imprinted polymer electrochemical sensor (MIP-ES) measurements. - Test PFOA- and PFOS-based sensors, including bench-scale work in tap and river or surface water, blinded surface-water trials, and field deployments using Joint Base Cape Cod samples. - Field samples include groundwater at different depths, surface water, high-concentration PFAS sites, and characterized samples collected at different times. - Compare sensor responses using differential pulse voltammetry at 1- and 15-minute incubation points; analyze results using statistical methods including unpaired t-tests and one-way ANOVA. - Equipment capability: Multichannel potentiostats capable of differential pulse voltammetry and cyclic voltammetry are needed. No manufacturer, model, part number, or equipment quantity is specified. - OEMs and vendors: No equipment OEMs, vendors, or commercial product brands are named. USGS will collaborate substantially on the research. - Funding and duration: Estimated total funding is $450,000, with $150,000 anticipated for the first year. The project is planned for three years, subject to progress and funding availability. - Research outputs: Results are expected to be shared through presentations, journal publications, and communications with partner agencies.

Description

The U.S. Geological Survey seeks a participating partner of the Northern Great Plains Cooperative Ecosystem Studies Unit to develop and test a quantitative ratiometric method for correcting solution-chemistry interference in molecularly imprinted polymer–electrochemical sensor (MIP-ES) measurements of complex environmental water matrices. Work includes bench-scale proof-of-concept testing and field-deployed trials, using PFOA- and PFOS-based sensors to investigate contaminants such as PFAS. The cooperative agreement anticipates one award, with one base year and two option years, subject to funding availability. Estimated total funding is $450,000, and cost sharing is not required.
