Sara Breitmeyer
Sara Breitmeyer is a chemist with the Pennsylvania Water Science Center.
Sara completed a B.A. in Chemistry & M.S. in Environmental Sciences and supports national USGS projects including advanced capabilities in modeling and the fate and effects of emerging contaminants, such as PFAS, pesticides and endocrine disrupting chemicals, in the environment. She also works as part of the Ecosystems Mission Area Environmental Health Program national tapwater infrastructure project through GIS mapping, web-scraping, database development, and R programming. She managed the organic geochemistry laboratory that specialized in the isolation and characterization of natural organic matter in surface water environments and investigated interactions between natural organic matter and trace metal contaminants (e.g. mercury). Other projects include validation of statistical & machine learning models, amphibian & fish health effects from water contaminants, and data collation strategies.
