From every side we hear of new threats to our water supply. Carcinogens, droughts, dam failures, global warming, hazardous wastes, deforestation, overpopulation, liability, and an aging infrastructure become household fears; this list grows longer and more foreboding to the average citizen. Some of these threats are real, while others are imaginary. Some we know how to overcome and others we can find ways to overcome, yet, for some, we are still helpless. The strength of a university lies in its success in stimulating inquisitive minds in critical examination of the problems of the world. People sense hope as experts find …

A Survey Of Compensatory Mitigation Within The Tidal Wetlands Of Virginia, Thomas A. Barnard, Pamela Mason
Reports
This study has as its primary purpose an examination of how compensatory mitigation has worked as a wetlands management tool to date in Virginia (i.e. how well theory has been put into practice). Our approach was to look at the overall use of compensation in coastal Virginia based on regulatory records and to examine as many existing created wetlands as possible within the tidal area of the state to determine how closely these projects have come, collectively, to fulfilling the compensatory goal of wetland replacement. Secondary objectives includes an examination of the literature regarding wetland compensation concept evaluation and to …

Draft- Nitrogen Loading And Ambient Chlorophyll-A In Hillsborough Bay (Tampa Bay), Florida: An Eutrophication Management Strategy, J.O. R. Johansson
Reports
The present report examines the past and current relationship between nitrogen loadings and ambient chlorophyll-a eutrophic subdivision of Tampa Bay (Task 1). A management strategy for eutrophication abatement, involving the reduction of present nitrogen loadings to levels which will sustain the desirable chlorophyll-a concentration and support persistent seagrass growth in the near future, is also presented for Hillsborough Bay (Task 3). The urgent need for a comprehensive long-term water quality and loading source monitoring program, specifically for Hillsborough Bay, is also discussed (Task 4).

Analysis Of Organic Pollutants In Sediments And Blue Crab (Callinectes Sapidus) Tissues : Final Report To Virginia State Water Control Board, John Greaves
Reports
The Elizabeth River is a highly industrialized waterway that divides the cities of Norfolk and Portsmouth at its confluence with the lower Chesapeake Bay. It is home to the largest Naval base on the East Coast, numerous ship repair facilities, bulk and containerized cargo facilities, industrial and urban activities and wood creosoting (preserving) operations (all except one have been abandoned). This degree of industrialization has resulted in the pollution of the river, with high concentrations of polynuclear aromatic hydrocarbons (PAH, Bieri et al., 1986). A major contributor to the pollution problem has been the wood processing industry which, due to …
