The Shermans Creek Watershed Monitoring Program calls on citizen scientists to conduct water quality sampling and to measure biological factors that indicate the health of the Pennsylvania creek and its response to pollution. Volunteers measure nitrate, temperature, dissolved oxygen, alkalinity, pH, and turbidity, and conduct regular bacteria monitoring and macroinvertebrate sampling at sites throughout the watershed.

The data will be used to provide public education, target areas for restoration and protection projects, and help the county and municipalities with land development plans that protect Shermans Creek.
