Water-quality assessment of the Potomac River Basin: occurrence of pesticides in the Great Valley Carbonate subunit Water-Resources Investigations Report 98 . Temporal trends in nitrate concentration in ground-water samples from wells in the Great Valley Carbonate of the Potomac River Basin (A) in aerobic environments (dissolved oxygen greater than Nitrate in Streams in the Great Valley Carbonate Subunit of the Potomac River Basin. in Ground Water in the Patuxent River Basin, Mary. land. U.S. Geological Survey Water-Resources. Elevated nitrogen concentrations in streams and ground water are common in areas of intensive row cropping, such as the northeastern part of the Potomac River Basin, and areas underlain by carbonate bedrock, such as the Great Valley. Organic nitrogen and phosphorus concentrations are typically low, except in streams during high flows.

Nitrogen-based fertilizers are used extensively in the White River Basin. Water samples were collected for nitrate analysis from monitoring wells in four networks in the basin. Ninety-four "shallow" wells were screened near the top of the uppermost aquifer encountered; the remaining 9 wells were paired with shallow wells but screened 18 to 45 feet deeper. Potomac River Basin Ground Water Assessment Project • Objective: To provide information and tools to assist jurisdictions in management and planning involving ground water availability, with emphasis on developing an integrated understanding of ground water and surface water resources in the Potomac River Basin • Approach. Relation Between Nitrate in Water Wells and Potential Sources in the Lower Yakima Valley, Washington. In , the U.S. Environmental Protection Agency (EPA) conducted a study to identify potential sources of nitrate contamination in groundwater and residential drinking water wells in the Lower Yakima Valley in central Washington State. withdrawal would be beyond the capacity of the aquifers to yield ground- water within a reasonable or feasible lift. There cannot be more than one well on each lot and new groundwater permits will be.

ity of ground water in the White and West Fork White River basin, Indiana (figure 1). The report is intended to provide background hydrologic information for persons interested in managing and developing the basin's ground-water resource. The White and West Fork White River basin in central and south-central Indiana spans the mid-section of the. Nitrate-N Concentrations in Ground Water Concentrations of nitrate-N in Idaho prior to land and water develop-ment probably were less than 1 mg/L. From through , the median concentration (50th percentile) of nitrate-N in Idaho ground water was about mg/L, and the range of con-centrations was. Thus, quantifying the discharge, nitrate load, and residence time of ground water in the Chesapeake Bay watershed assists in developing an understanding of the movement of nutrients from their sources to streams. Some of the nutrients that are applied to the land surface, especially nitrogen, infiltrate into the underlying ground-water system.
