摘要

Samples of nitrogen-source material, soil, and water were collected from several small, primarily single-source subbasins in the Lower Susquehanna River Basin during 1988-90 to determine the feasibility of using measurements of stable isotope ratios of carbon, nitrogen, and sulfur to identify sources of nitrogen (N) in stream water. Chemical and isotopic compositions were measured for six N-source types consisting of rain water, forest leaf litter, synthetic fertilizer, farm-animal manure, municipal-sewage effluent and sludge, and septic-tank effluent and sludge. Compositions of associated, nearby samples of topsoil, subsoil, runoff water, and stream water were measured to evaluate changes in compositions of transported N-containing materials near the N source.
