Specifically, pesticide runoff can disrupt hormonal, reproductive, and developmental processes in aquatic organisms, yet non-point source pollution is difficult to trace and quantify. In Citation: Scully-Engelmeyer, K.; Oregon, U.S.A., state and federal forestry pesticide regulations, designed to meet regulatory water Granek, E.F.; Nielsen-Pincus, M.; quality requirements, differ in buffer size and pesticide applications. We deployed passive water Lanier, A.; Rumrill, S.S.; Moran, P.; samplers and collected riverine and estuarine bivalves Margaritifera falcata, Mya arenaria, and Cras- Nilsen, E.; Hladik, M.L.; Pillsbury, L.
