Chester County, Pennsylvania Active
Paired Air and Water Temperature Monitoring
Next Generation Water Observing System (NGWOS)
Since 1969, the Pennsylvania Water Science Center has had a cooperative program with Chester County to measure and describe water resources. Cooperation has been primarily with the Chester County Water Resources Authority, with participation from the Chester County Health Department. This partnership provides Chester County with scientific information for water-resources management.
Chester County Monitoring Network Web App
The Chester County Water Resources Authority (CCWRA) was created in 1961, primarily for land acquisition and planning for flood-control and water-supply projects. With the backing of the Brandywine Valley Association, the CCWRA started its first cooperative project with the USGS in 1969. It was a study of the water-quality condition of Chester County streams with an emphasis on benthic-macroinvertebrates and stream chemistry.
The types of projects and data collection conducted by the USGS have changed with the needs of Chester County and the mission of the CCWRA. Chester County is experiencing rapid population growth resulting in considerable stress on water resources. In response, the CCWRA has broadened its focus from flood control to water-supply planning, water quality, and groundwater and surface-water management. The results of USGS studies are used by the CCWRA and other county agencies, including the Planning Commission, Health Department, and Parks and Recreation, for conducting day-to-day activities and planning for future growth. The results also are used by the CCWRA to provide guidance and technical assistance to municipalities, water suppliers, industrial dischargers, watershed and conservancy associations and other civic organizations, state and Federal agencies, river basin commissions, and the private sector.
The cooperative water-resources program benefits not only citizens of Chester County but also those in other states as the headwaters of several interstate drainages lie within the county. In addition, the program serves the interests of the Federal government as innovative studies conducted in Chester County provide methods and interpretations that often can be used nationwide. Major program thrusts include collection of surface-water, groundwater, and water-quality data and interpretive studies.

Estimated fecal coliform bacteria concentrations using near real-time continuous water-quality and streamflow data from five stream sites in Chester County, Pennsylvania, 2007–16
Several streams used for recreational activities, such as fishing, swimming, and boating, in Chester County, Pennsylvania, are known to have periodic elevated concentrations of fecal coliform bacteria, a type of bacteria used to indicate the potential presence of fecally related pathogens that may pose health risks to humans exposed through water contact.

Spray irrigation is a method for disposing of secondary treated municipal wastewater by spraying it on the land surface (fig. 1). The sprayed wastewater either evaporates into the air, soaks into the soil, or percolates through the soil and recharges the ground water. Land application of wastewater has advantages over conventional means of disposal by direct discharge to streams because the wastewAuthorsCurtis L. Schreffler, Daniel G. GaleoneEffects of spray-irrigated treated effluent on water quantity and quality, and the fate and transport of nitrogen in a small watershed, New Garden Township, Chester County, Pennsylvania
An increasing number of communities in Pennsylvania are implementing land-treatment systems to dispose of treated sewage effluent. Disposal of treated effluent by spraying onto the land surface, instead of discharging to streams, may recharge the ground-water system and reduce degradation of stream-water quality.

Biological, chemical, and habitat data have been collected from a network of sites in Chester County, Pa., from 1970 to 2003 to assess stream quality. Forty sites in 6 major stream basins were sampled between 1998 and 2000.
