Wye River, Maryland

The total amount of atrazine reaching the Wye River, Maryland, estuary depended on the quantity applied in the watershed and the timing of runoff. In years of significant runoff. 

Three atmospheric sites in the Chesapeake Bay watershed, and in close proximity to the Bay itself, were continuously monitored in 1997/98 as part of a large EPA-funded study of the atmospheric speciation of metals and organic contaminants and of the concentration of these constituents in wet and dry deposition (77, 18, 20, 21). There was an urban site, located on the roof of the Science Center (SC) in downtown Baltimore (Figure 1) and two more rural sites. These sites were the Chesapeake Biological Laboratory (CBL) at the mouth of the Patuxent River (about 60 km from the nearest city) and Stillpond (STP), on the eastern shore of the northern Chesapeake Bay and within 20 km of Baltimore (Figure 1). Previous studies occupied sites at Elms, Wye and Lewes (Figure 1) and a site in western Maryland near Frostburg (FRB).
