North Carolina Agricultural and Technical State University (N.C. A&T) is managing and operating NC 17 (one Mercury Deposition Network, MDN and one National Trends Network, NTN) in concordance with guidelines and procedures of the National Atmospheric Deposition Program (NADP) technical manual.

Mercury Deposition Network (MDN) provides a national database of weekly concentrations of total mercury in precipitation and the seasonal and annual flux of total mercury associated with wet deposition. National Trends Network (NTN) provides a national database of weekly information on precipitation chemistry. The NTN is the only network providing a long-term record of precipitation chemistry across the United States.

Investigation of wet deposition of mercury in eastern North America using weekly observations from Mercury Deposition Network (MDN) stations that are located along the 80° west longitude line is in progress. These N-S stations include ON07, PA30, PA21, PA37, NC17, NC26, SC19, SC03, GA33, FL34, FL95, FL97, and FL11. Preliminary data on variations of wet deposition of mercury across the N-S stations for selected periods will be presented. The monitoring of pollutants flow into the ecosystem (NADP data) provides information about the effects of wet deposition on human populations, ecosystems and agricultural systems.
