There is a high probability of detecting PFAS in public drinking water systems that are close to potential PFAS user sites . In addition, precursor chemicals may be present that will chemically transform over time into highly persistent PFAS . A case study was done using geospatial and statistical modelling for Kentucky, in which PFAS risk-areas were analysed, identifying potential nearby high-risk drinking water systems. The result of this research was verified by the sampling result generated by the Kentucky Department of Environmental Protection Agency (KDEP) . KDEP sampled eighty-one (81) public drinking water systems, of which forty-three are surface water sources and thirty-eight are groundwater sources. In 2019, KDEP directly tested for eight (8) PFAS, including Perfluorobutane sulfonate (PFBS), Hexafluoropropylene oxide-dimer(HFDO-DA or Gen-X), perfluoroheptanoic acid (PFHpA), Perfluorohexane sulfonate (PFHxS), Ammonium 4,8-dioxa-3Hperfluorononanoate (ADONA), PFOA, PFOS, and Perfluorononanoic acid (PFNA) . FAIR (Findable, Accessible, Interoperable and Reusable) is a set of guiding principles for managing publicly accessible data that emphasizes making data findable with unique identifiers and search mechanisms, easily accessible, i.e. downloadable, interoperable between computer systems and programs, and reusable for future usecases . For around a decade, ideas of FAIR-like stewardship have been implemented by several stakeholders , especially to implement infrastructure that enables machine-actionable curation, conversion, and reuse of data .
