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. The availability of near real-time continuAuthorsLisa A. SeniorFilter Total Items: 64Naturally occurring radionuclides in the ground water of southeastern Pennsylvania
Naturally occurring radionuclides in the ground water of southeastern Pennsylvania may pose a health hazard to some residents, especially those drinking water from wells drilled in the Chickies Quartzite. Water from 46 percent of wells sampled in the Chickies Quartzite and 7 percent of wells sampled in other geologic formations exceeded the U.S. Environmental Protection Agency (USEPA) maximum contAuthorsRonald A.

Between September 1997 and October 1998, nine monitor wells were drilled at the AIW Frank/Mid-County Mustang Superfund Site in Chester County, Pa., to determine the horizontal and vertical distribution of contaminated ground water migrating from known contaminant sources. The U.S. Geological Survey conducted borehole geophysical logging and borehole television surveys in these boreholes to identifAuthorsR.W. Conger, D.J. Goode, R. A.

Low-flow statistics for many streams in Chester County, Pa., were determined on the basis of data from 14 continuous-record streamflow stations in Chester County and data from 1 station in Maryland and 1 station in Delaware. The stations in Maryland and Delaware are on streams that drain large areas within Chester County. Streamflow data through the 1994 water year were used in the analyses. The lAuthorsCurtis L.

Radon-222 concentrations in ground water in 31 geologic units in Chester County, Pa., were measured in 665 samples collected from 534 wells from 1986 to 1997. Chester County is underlain by schists, gneisses, quartzites, carbonates, sandstones, shales, and other rocks of the Piedmont Physiographic Province. On average, radon concentration was measured in water from one well per 1.4 square miles, tAuthorsLisa A.

Since 1969, the U.S. Geological Survey (USGS) has had a cooperative water-resources investigation program with Chester County to measure and describe the water resources of the County. Generally, the USGS provides one-half of the program funding, and local cooperators are required to provide matching funds.
