Andrew G Reif
Drew Reif is Downingtown Office Chief and leads the office's Hydrologic Studies Unit.
I have been working at the U.S. Geological Survey for over 30 year since I graduated from West Chester University with a BS in Biology. I have worked in the USGS offices in Malvern, Exton, and now Downingtown Pa.
The main focus of my work at the USGS has been with the Stream Conditions of Chester County Biological Monitoring Network. The Network was established in 1970 and I have been the project chief since 1990. My work includes the collection and identification of macroinvertebrate samples and data analysis.
Since 2004 I have also been the project chief for the Pennsylvania Water Quality Network (WQN). The WQN is a statewide water-quality collection network that is operated with the Pennsylvania Department of Environmental Protection. Through the WQN work I have also been involved with sampling and interpretation of emerging contaminant compounds including pharmaceuticals, hormones and organic wastewater compounds.

Assessment of stream quality using biological indices at selected sites in the Brandywine Creek basin, Chester County, Pennsylvania, 1981-97
In 1970, the Chester County Water Resources Authority (Pennsylvania) and the U.S. Geological Survey (USGS) established a longterm water-quality network with the goal of assessing the quality of streams in the county and understanding stream changes in response to urbanization using benthic-macroinvertebrate data. This database represents one of the longest continuous water-quality data sets in the

Physical, chemical, and biological data for selected streams in Chester County, Pennsylvania, 1995-97
Physical, chemical, and biological data were collected at 51 sampling sites in Chester County, Pa., from 1970 through 1997 as part of the Stream Conditions of Chester County Program. This report presents data collected from 43 sites from 1995 through 1997 that constitute a continuation of the program. Physical data include water temperature, instantaneous stream discharge, pH, alkalinity, specific

Hydrogeology and water quality of the West Valley Creek Basin, Chester County, Pennsylvania
The West Valley Creek Basin drains 20.9 square miles in the Piedmont Physiographic Province of southeastern Pennsylvania and is partly underlain by carbonate rocks that are highly productive aquifers. The basin is undergoing rapid urbanization that includes changes in land use and increases in demand for public water supply and wastewater disposal. Ground water is the sole source of supply in the

Metals, pesticides, and semivolatile organic compounds in sediment in Valley Forge National Historical Park, Montgomery County, Pennsylvania
The Schuylkill River flows through Valley Forge National Historical Park in Lower Providence and West Norriton Townships in Montgomery County, Pa. The concentration of selected metals, pesticides, semivolatile organic compounds, and total carbon in stream-bottom sediments from Valley Forge National Historical Park were determined for samples collected once at 12 sites in and around the Schuylkill

Geohydrology and simulation of ground-water flow in the Red Clay Creek Basin, Chester County, Pennsylvania, and New Castle County, Delaware
The 54-square-mile Red Clay Creek Basin, located in the lower Delaware River Basin, is underlain primarily by metamorphic rocks that range from Precambrian to Lower Paleozoic in age. Ground water flows through secondary openings in fractured crystalline rock and through primary openings below the water table in the overlying saprolite. Secondary porosity and permeability vary with hydrogeologic un
