Surface Water-Quality Monitoring Network (WQN)


Pennsylvania’s Statewide Surface Water-Quality Monitoring Network (WQN) currently consists of 124 sites that are sampled between 6 and 20 times a year. Chemical analysis includes nutrient, major ions, and selected metals. Pesticide sampling is conducted twice a year at 5 locations. Biological sampling for benthic macroinvertebrates is conducted annually at 80 sites.

Caribbean-Florida Water Science Center Watercams for Florida

Webcams have been installed at several real-time stream-gaging sites. The webcams provide valuable information to the National Weather Service, emergency managers, and area residents to evaluate real-time conditions in river environments during storms. The visual record of flooding and other river events also provides valuable research data for the USGS. Many of these webcam installations are...

Groundwater Quality Monitoring Network


Pennsylvania’s Statewide Fixed Station Groundwater Quality Monitoring Network (GWMN) currently consists of a set of 27 groundwater wells located in 26 counties that are sampled twice a year for a host of chemical constituents. The GWMN was established to characterize the ambient groundwater quality of Pennsylvania aquifers and to provide a temporal dataset to address seasonal...

Assessment of the immune status of wild and laboratory-maintained smallmouth bass

Deaths of young-of-year smallmouth bass in the Chesapeake Bay drainage has been noted since 2005. Studies of affected fish have found bacterial, viral and parasitic infections. Mixed infections suggest these fish are immunosuppressed. Understanding the role of specific pathogens and environmental factors that contribute to their presence is important but equally important is the understanding...

Trace Metals in San Francisco Bay Clams

The clams Potamocorbula amurensis and Corbicula fluminea were collected at a variety of sites in the San Francisco Bay/ Delta beginning July 1990 and ending February 2010. These invasive species were used as biosentinels of the fate, transport, and effects of trace metals in the San Francisco Bay ecosystem.

Linking Selenium Sources to Ecosystems: Mining

Environmental sources of selenium (Se) such as from organic-enriched sedimentary deposits are geologic in nature and thus can occur on regional scales. A constructed map of the global distribution of Se source rocks informs potential areas of reconnaissance for modeling of Se risk including the phosphate deposits of southeastern Idaho and the coals of Appalachia.
