Water quality assessment data
Data collected for the Water Quality Assessment project was used in determining the impacts that combined sewer overflows have on human and aquatic life in the Duwamish River and Elliott Bay. Data were collected from the water column, combined sewer overflow discharges, sediments, certain animal tissues, and semi-permeable membrane devices (SPMD). Data were analyzed for concentrations of select heavy metal and organic pollutants, concentrations of fecal coliform bacteria, and conventional parameters (temperature, salinity, total suspended solids, dissolved oxygen, nutrients, and pH). Unless stated otherwise in the individual files, all water column metals are reported in mg/L (milligrams per liter), all water column organics are reported in ug/L (micrograms per liter), sediment metals are reported in mg/kg (milligrams per kilogram) wet weight, and sediment organics are reported in ug/kg (micrograms per kilogram) wet weight. Following are the available data files.
