Within the framework of the 1984 Program of the Maryland Water Resources Research Center, three projects were focused on questions of pollution of surface and ground water and one on acid rain. An information-transfer project focused on the protection of ground-water supplies. In a project to assess nitrogen and phosphorus losses via subsurface ground-water flow from conventional and no-till corn watersheds, evidence was obtained that the leaching of nitrates into percolate or ground water is not enhanced by the use of no-till cultivation. No phosphate was found in percolate samples from either no-till or conventional cultivation treatments. A two-year study was conducted to assess the accumulation of toxic metals in the sediments of Maryland's Eastern Shore rivers. In a project to determine the impact on human health of contaminants present in sludge applied as soil amendment, ground and surface water have been analyzed for mutagenic compounds. Preliminary information on acidity in rainfall indicates increased levels of H(+), SO4(2-), Pb, and Mn over a control area in Tennessee.
