Ability to distinguish between human and animal fecal pollution is important for risk assessment and watershed management, particularly in bodies of water used as sources of drinking water or for recreation.
PCR-based methods were used to determine the source of fecal pollution and to characterize the relationship between fecal pollution and land use, surface water nutrients, precipitation, and other in-stream indicators of water quality.
Stream water samples (n = 193) were collected monthly over a two year period from ten channels draining subwatersheds with different land use intensities.

Culture- and PCR-based measurements of fecal pollution were determined and compared to hydrologic and land use indicators.
Stream water samples (n = 235) were collected monthly over a two year period from ten streams draining headwatersheds with different land use intensities ranging from mostly forested, rural agricultural, to high-density residential.
The sampling effort was part of a multidisciplinary program designed to characterize and manage water quality in the 1300 km2 East Fork Watershed of Southwestern Ohio.
