Abstract

Physical, chemical, and biological data were collected at 51 sampling sites in Chester County, Pa., from 1970 through 1994 as part of the Stream Conditions of Chester County Program. This report presents data collected from 1981 through 1994. Physical data include water temperature, instantaneous stream discharge, pH, alkalinity, specific conductance, and dissolved oxygen. Chemical data include laboratory determinations of nutrients, major ions, and selected metals in whole water samples and selected metals, pesticides, gross polychlorinated biphenyls (PCB?s), gross polychlorinated napthalenes (PCN?s), and total carbon in stream-bottom sediment samples. The biological data consists of benthic macroinvertebrate population analyses and diversity indices. Chester County is undergoing rapid urbanization as agricultural lands are converted to residential, commercial, and industrial areas. The purpose of the Stream Conditions of Chester County Program is to further the understanding of stream habitat and chemical changes in response to this urbanization.
