Kepone In The James River Estuary: Past, Current And Future Trends, Michael A. Unger, George G. Vadas

Reports

In late 1975, a manufacturing facility in Hopewell, VA had not only exposed workers to the chlorinated pesticide, Kepone, but had also severely contaminated the James River estuary. To assess the potential risk to the public, Virginia initiated a finfish-monitoring program in late 1975. Over the next 40 years over 13,000 samples were collected from the James River and Chesapeake Bay and analyzed for Kepone. Kepone production was eventually banned worldwide. The average Kepone concentrations found in most species began falling when the production of Kepone ended, but the averages remained over the action limit of 0.3 mgkg^-1 until …

Chemical And Toxicological Characterization Of The Upper York River, Virginia The Mattaponi And Pamunkey Rivers, Morris H. Roberts Jr., Mark Richards, Peter F. Delisle

Reports

This study describes the most extensive effort to characterize the chemistry, toxicology and community of the sediments of the Mattaponi and Pamunkey Rivers. This was accomplished using a study design modified to expand the number of stations occupied by reducing the cost of analyses by compositing replicate samples collected from each study site rather than performing toxicity tests on these samples individually. In previous studies, the variability in field replicate samples was equivalent to the variability in laboratory replicates. This design has long been used to analyze samples for various chemical contaminants as a cost savings endeavor. More ....

Hypoxia In The Lower Rappahannock Estuary, Albert Y. Kuo, Mohamed Z. Moustafa

Reports

There are several objectives to this study. The immediate objective is to collect a comprehensive and consistent set of field observations to better describe the hypoxic condition in the Rappahannock River. Other objectives can be classified as short and long term goals.

Long term: (1) Identify and quantify the processes contributing to the dissolved oxygen budget in deep waters, and explain the variabilities among the three Virginia major tributary estuaries. (2) Provide information for resource management so that the James River can be protected from hypoxic problems and, perhaps, the problems in the York and Rappahannock Rivers can be alleviated. …

The Present State Of Organic Xenobiotics In The Chesapeake Bay - A Synthesis Paper, R. J. Huggett, R. H. Bieri, P. O. Defur, W. G. Macintyre, P. Shou, C. L. Smith, C. W. Su

Reports

This manuscript discusses the results of the first two and one half years of a three-year study designed to determine the present state of xenobiotic compounds in the Chesapeake Bay. It shows that polynuclear aromatic hydrocarbons are the most frequently encountered compounds and are the most abundant. Concentrations are highest in the Northern Bay with several sources implicated. During this study an apparent dumping of the pesticide, DDT, occurred. Either the quantity disposed of was small enough or the assimulation capacity was large enough that no adverse effects were noted. The detection by us of 6-phenyldodecane in bottom sediments of …

Ecological Study Of The Tidal Segment Of The James River Encompassing Hog Point (Site Of The Surry Nuclear Power Station) : Completion Report, Robert A. Jordan, Patrica A. Goodwin, Charles E. Sutton

Reports

The Surry Power Station discharges cooling water into the transition zone of the James River. Phytoplankton, zooplankton, benthos, and fouling organism communities were sampled during the years 1969 through 1978, which encompassed a preoperational and an operational period. Temporal changes in the biotic communities followed seasonal patterns of temperature and salinity in the study area, and reflected inherent reproductive patterns of the organisms. Spatial patterns reflected the transport of organisms from the river in the vicinity of the intake to the zone encompassed by the discharge plume, as well as periodic bursts of meroplankton generation in the cooling water canals. …

An Environmental Assessment Of The Summer Plankton In The Vicinity Of The C.P. Crane Generating Station, George C. Grant, Stephen P. Berkowitz

Reports

A preliminary survey of summer plankton in ·waters surrounding the C. P. Crane generating station in Bengies, Maryland, revealed several possible effects of plant operation. These perturbations were separated into apparent small-scale and large-scale effects:

Small-scale effects were limited to the immediate discharge region of Saltpeter Creek and included (1) occasional elevation of temperatures at the surface (in August) to above the lethal limit for most zooplankton and sufficiently high to inhibit photosynthesis, (2) a decrease in chlorophyll-a, seen in July and August, (3) a sharp decrease in productivity, also in July and August, and (4) absence of a common …

Acute Effect Of Free Chlorine On Selected Estuarine Invertebrates And Vertebrates : Final Report, Morris H. Roberts, Robert J. Diaz

Reports

The objective of this project was to determine acute toxic effects of chlorine on selected estuarine organisms found adjacent to the projected outfall of a sewage treatment plant in the lower York River. The test species specified under contract were ovster (Crassostrea virginica) and clam (Mercenaria mercenaria) larvae, Acartia tonsa (a dominant copepod), and the fishes, menhaden (Brcvoortia tyranus), pipefish (Svngnathus fuscus), blennies (Hypsoplennius hentzi) and sheepshead minnow (Cyprinodon variegatus). The parameter of interest in the tests was mortality when the animals were exposed to a constant level of chlorine for a 48 or 96 hr period.

Special Purpose Areas In Virginia's Coastal Zone, J. B. Pleasants

Reports

The Virginia Institute of Marine Science is charged with the responsibility of advising state management agencies on matters relating to the environments and resources of the coastal zone of Virginia. Under this broad requirement, we have been specifically assigned the task of recommending an ocean-dumping policy for the Commonwealth. This paper, a survey of specially designated areas in coastal waters of the state, is designed to provide some of the background material required in the development of such a policy.

Concentration Of Suspended Radioactive Wastes Into Bottom Deposits., Dexter S. Haven

Reports

During recent years rapid advances in nuclear technology have increased the probability of accidental contamination of our coastal estuarine waters by several routes. The chances of such contamination appear remote, but in the event of a nuclear accident, it would be imperative to understand processes which will disperse or concentrate radioactive materials. In coastal waters the disposal or transport of radionuclides in concentrations exceeding the maximum permissible concentration is affected by tidal action and by the volume of inflowing fresh waters. During the period of transport by coastal or estuarine currents, physical and chemical forces will produce abiotic sedimentation. The …

Final Report On Results Of Operation James River; An Evaluation Of The Physical And Biological Effects Of The Proposed James River Navigation Project, William J. Hargis Jr.

Reports

A comprehensive study of the physical and biological characteristics of the James Estuary has been carried out by oceanographers of the Virginia Institute of Marine Science under contract with the Virginia Commission of Fisheries. This research project, under way for three years, has been directed especially to the effects of the proposed James River Navigation Project channel dredging on physical features--i·~.,the structure and dynamics, of the estuary, and indirectly on oyster production. Five separate phases were carried out under the project (called Operation James River). These involved: 1) accumulation and study of relevant literature and data, 2) research into the …
