Wetlands Evaluation And Management In Virginia, Eileen L. Shea, N. Bartlett Theberge

Reports

Complex biotic communities which have lately been recognized as being of vital importance to aquatic and upland ecosystems have evolved at Virginia's land-water interface. Most obvious are the beaches and vast intertidal stands of halophytic (salt-tolerant) plants on the periphery of the Atlantic Ocean, Chesapeake Bay and their subordinate estuaries. Less obvious, but no less important, are nonvegetated intertidal flats and coastal freshwater marshes. Inland swamps and freshwater marshes complete the inventory; though more limited in extent than their coastal analog. Complex biotic communities which have lately been recognized as being of vital importance to aquatic and upland ecosystems have …

Disinfection Efficiency And Relative Toxicity Of Chlorine And Bromine Chloride: A Pilot Plant Study In An Estuarine Environment, Norman E. Leblanc, Morris H. Roberts

Reports

The present study was conducted by the Virginia Interagency Task Force on Chlorine to compare the relative merits of bromine chloride and chlorine as wastewater disinfectants. Operational and disinfection qualities of both halogens and the relative toxicities of the treated effluents were studied in a pilot scale system. Three specific objectives were pursued; 1. an evaluation of the relative disinfection capabilities of the two halogens; 2. an assessment of the toxicity of each effluent stream to juvenile spot; and 3. an analysis of the halogenated organics produced in treated and disinfected effluent. The results of studies directed at the first …

The Quality Of Storm Runoff From Different Kinds Of Land Surfaces In The Drainage Basin Of Westhampton Lake, Richmond, Virginia, Margaret Emil Coppedge

Master's Theses

Samples of runoff were collected during storms from four different areas within the drainage basin of Westhampton Lake, Richmond, Virginia, between October, 1977, and January, 1978. The areas were a residential area, concrete street gutter, asphalt parking lot, and broadleaf forest.

The samples were analyzed for pH, levels of reactive phosphate, nitrate, and turbidity, and their effects on the growth of algae from Westhampton Lake.

The pH of runoff from the residential area, gutter, and forest usually ranged between 6-7 and the parking lot usually ranged between 4-5. Levels of turbidity varied considerably between storms and areas. Runoff from the …

Summary Of The Hampton Roads 208 Water Quality Modelling Studies, Bruce J. Neilson

Reports

The purpose of· the Hampton Roads 208 Study is to assess the present and future water quality conditions in the study area and to develop a wastewater management plan to achieve certain water quality goals. The study included all major estuaries in the area and, among other thing·s, took account of population and industrial growth, effluent quality {as mandated by PL92-500) and nonpoint sources of pollution. Land use maps for 1976, estimates of future land use, population projections and many other elements of the study initiated in 1974 provided the foundation upon which the water quality work was based. Projections …
