Peter C Van Metre

Peter Van Metre retired in 2020 from the Earth System Processes Division of the USGS Water Mission Area. He currently is a Scientist Emeritus focused on completing the Regional Stream Quality Assessment (RSQA) of the USGS National Water Quality Assessment (NAWQA) project.



I started with the USGS in 1980 as a Hydrologic Technician in Tampa, Florida, eventually becoming a Research Hydrologist with the NAWQA project. From 1993 to 2012, I led a small team of researchers investigating long-term contaminant trends using lake and reservoir sediment cores. In 2012, with the start of the third decadal cycle of NAWQA, I was chosen to help design and lead the Regional Stream Quality Assessment (RSQA) studies. The RSQA team included geochemists, biologists, data management specialists, and hydrologists, and was charged with assessing stream quality and ecological condition and determining the effects of multiple chemical and physical stressors on stream biota. From 2013 to 2017, five large regions of the country were assessed, and we continue to interpret the wealth of data produced and to publish those findings.
