The population of coastal counties in the United States is over six-fold higher than non-coastal counties and population density along the Atlantic coast is much greater than all other coasts in the nation. Many areas around the Chesapeake Bay watershed are participating in this growth and extensive interstate construction is planned for this region. A wide array of primary ecological risks to the Chesapeake Bay exists, and may be classified as biological, physical, or chemical. Biological risks range from physical threats to motorists and animals to genetic risks to local flora and fauna populations. Island biogeography theory can be used …

Groundwater discharge supplies a significant portion of the inorganic nutrients entering the Chesapeake Bay. This discharge increases nutrient concentration in surface waters, which may result in increased macrophyte growth, reductions in· submerged aquatic vegetation and alteration of habitat. Human activities adjacent to the shoreline greatly increase nutrient concentration in the underlying groundwater, and so affect the overall nutrient input by groundwater seepage. In order to quantify the effect of land use on groundwater nutrient loading in the Virginia coastal plain we have installed monitoring wells in a variety of near shore environments adjacent to the James and York Rivers. Since …

An interactive online computerized database for retrieval of chemical analytical information on volatile and extractable organic compounds, and the priority pollutant metals has been developed. Current information about samples from the Chesapeake Bay region in Virginia and Maryland are available. This database stores information on organic compounds in effluent, water, tissue, and sediment in a format which does place restrictions on the number of compounds per sample. It includes various QA/QC items as well as the analyst's assessment of the validity of the data. A variety of keyed retrieval options permits selection of reporting format, and flagging of items exceeding …
