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

Plant Geography And Water Quality Data For Chesapeake Bay Waters Of Virginia's Eastern Shore, John C. Munday Jr., Paul L. Zubkoff, J. Ernest Warinner Iii, Elvira Ferrez-Reyes, Hayden H. Gordon, Kenneth A. Moore
Reports
Plant geography and water quality data were collected in shallow water near Cape Charles and Occohannock Creek, Virginia on two occasions. Data from April, 1978 included hydrography, distribution and abundance of -submerged aquatic vegetation, phytoplankton census, and water clarity data. Data from May, 1978 included hydrography, phytoplankton census, water clarity, and primary productivity data. The May data collection was coincident with an overflight of the NASA JSC C-130 aircraft (6600 m) acquiring color infrared photography and multispectral scanner data; cell concentrations reached 105/ml, chlorophyll~ 72 pg/1, and suspended sediment 94 mg/1. i

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 …
