Abstract

Data on the quantity and quality of groundwater and surface water in the drainage basins of Jacobs Creek, Stony Brook, and Beden Brook upstream from U.S. Route 206 in west-central New Jersey were collected from October 1, 1986, through September 30, 1988. Water levels measured in 74 wells ranged from 49 to 453 ft above sea level. The water-table surface generally mimicked topography; however, the water-level altitude in one well indicates the possibility of local interbasin groundwater flow. Calcium and bicarbonate were the most abundant cation and anion in most of the 25 groundwater samples. With one exception, concentrations of nutrients, trace elements, organic carbon, and volatile organic compounds in groundwater samples were less than U.S. Environmental Protection Agency primary drinking-water regulations. Stream low-flow measurements made twice at each of 63 sites indicate that both discharge and runoff increased downstream for most reaches of Jacobs Creek, Stony Brook, and Beden Brook. For main-stem sites, the highest base-flow runoff occurred at site 01462733 on Jacobs Creek; the greatest discharge was measured at site 01401100 on Stony Brook. The flow-duration curve for Stony Brook for 1987-88 indicates a wetter- than-normal period for the area. Results of surface-water-quality analyses indicate that calcium and sodium plus potassium were the dominant or codominant cations, and bicarbonate and chloride were the dominant or codominant anions in most samples. Concentrations of nutrients typically exceeded those needed to support surplus algal growth. Concentrations of trace elements generally were less than U.S. Environmental Protection Agency primary drinking-water regulations. Bottom-sediment samples contained several persistent organic compounds. Significant downstream variations were found in concentrations of copper and lead in Jacobs Creek and Stony Brook. Results of macroinvertebrate community sampling indicate an input of nutrients to several stream sections on Jacobs Creek, Stony Brook, and Beden Brook.
