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.

A study of ground-water quantity and quality was conducted in the Big Elk Creek Basin, a rural area undergoing rapid growth. The 79.4-square mile study area is in the Piedmont Physiographic Province and is underlain almost entirely by crystalline rocks.

Biological, chemical, and physical data were collected from a network of 43 sites in Chester County, Pa., from 1981 to 1997. The goal of the network is to assess stream conditions and determine trends in benthic-macroinvertebrate and water-chemistry data.

The Brandywine Creek in Chester County is used for recreation and as an important source of drinking water. For this study, 40 sites were established for collection of water samples for analysis of fecal coliform and Escherichia coli bacteria in 1998-99. Samples were collected during base-flow conditions and during five storms in which rainfall exceeded 0.5 inch. During base- flow conditions, theAuthorsD.A.
