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 years 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.

Stream conditions monitoring network in Chester County, PA
This geonarrative describes the stream biological monitoring conducted as part of the Chester County - U.S. Geological Survey Cooperative Water Resources Program.
Philadelphia Water Resources Monitoring
The Philadelphia Water Department (PWD) and USGS have been working together to create and expand the water-quality monitoring network for Philadelphia. Data from these gaging stations will allow PWD scientists and engineers to monitor spatial and temporal water quality/quantity trends in support of watershed restoration initiatives occurring in Philadelphia.
Chester County (Pennsylvania) Monitoring Networks
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.
The Chester County Monitoring Network web tool provides near real-time water data.
