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.
