Status Of The Public Oyster Resource Of Virginia - Fall 1992, Bruce J. Barber

Reports

oysters have been harvested from Virginia waters as long as humans have i):'lhabited the area. Depletion of natural stocks in the late 1880's led to the establishment of regulations by public fisheries agencies. A survey of bottom areas in which oysters grew naturally was completed in 1896 under the direction of Lt. Baylor, USN. These areas (over 243,000 acres) were set aside by legislative action for public use and have come to be known as the Baylor survey Grounds or Public oyster Grounds of Virginia, and are presently administered by the Virginia Marine Resources commission (VMRC).

Reports

Y. Peter Sheng, the Principal Investigator of the proposed study, has developed and applied three-dimensional hydrodynamic models since 1972. These models were developed for a variety of water bodies (including estuaries, lakes, and coastal waters) for a variety of government agencies (e.g., USEPA, USGS, SBNEP, USAE, SFWMD, and SJRWMD) and petroleum companies (Standard Oil and Mobil) to solve a variety of problems. Basically, the nature of the problem and the water body determines the purpose of the modeling study and hence the features and capabilities of the model.

Dissolved Oxygen Measurements In The Machipongo River System Near Willis Wharf, Virginia, Bruce Neilson, Cheol Mo, Rodney Jackson

Reports

Most aquatic organisms require· oxygen to survive and consequently, the dissolved oxygen (DO) content of the water is one of the most important measures of water quality. Sources of oxygen are the atmosphere and photosynthesis. Oxygen is consumed by plants and animals during respiration and by microorganisms that decompose organic matter. The more sources and sinks of oxygen, the more difficult it is to understand and predict the oxygen dynamics of a river system. Grossly polluted systems turn out to be quite simple, because the pollutant source dominates. Natural, unimpacted systems often show a balance between a number of sources …

A Plan Of Study Submitted To The Florida Department Of Environmental Regulation Southwest District, Department Of Sanitary Sewers Bay Study Group

Reports

The proposed study will examine effects of nutrient limitation on phytoplankton growth rates in Tampa Bay. The response of growth rate to changes in nutrient additions will be indicated through changes in algal biomass (chlorophyll-a) and fixation of CO2 (C‑14­ uptake). The selected method is similar to methods currently used by the states of Maryland and Virginia for determination of nutrient limitation in Chesapeake Bay waters (Fisher et al. 1992a and b). The proposed study will, therefore, not only yield valuable information about nutrient limitation in Tampa Bay, but will also allow for comparison of information between Tampa Bay and …

Recent Improvements Of Water Quality And Biological Indicators In Hillsborough Bay, A Highly Impacted Subdivision Of Tampa Bay, Florida, J.O. R. Johansson, R. R. Lewis Iii

Reports

Hillsborough Bay, the eastern uppermost section of the Tampa Bay system, is surrounded by a large metropolitan complex, supports extensive industrial activity, and serves as a major shipping port of fertilizer products. The Bay was determined to be highly eutrophic during the late 1960s. The City of Tampa's primary sewage treatment plant and runoff from fertilizer industry activities were considered as the major sources of excessive nutrient loading. Loadings form both these sources have been reduced during the last 10 years, which has probably been the leading cause of improved water quality parameters such as water clarity, dissolved oxygen, and …

Nonparametric Stratigraphic Interpretation From Drill Log Data, Upmanu Lall, A. I. Ali

Reports

Near surface groundwater contamination is a widespread problem. The potential for contamination of deep aquifers in such areas depends on the vertical hydraulic gradient as well as the extent and location of interconnection between the upper and lower aquifers. In alluvial, sedimentary environment, the geologic units are typically weakly connected lenses or layers of high or low conductivity with variable size, geometry and orientation. Drill logs provide qualitative, local information on such aquifer heterogeneities. A binary (high or low conductivity) indicator function is used to describe the aquifer system. A nonparametric statistical methodology for assessing the probability that a particular …

Composting Of Explosives Contaminated Soil Using The White Rot Fungus Phanerochaete Chrysosporium, Michael J. Mcfarland, Shashi Kalaskar, Eric Baiden

Reports

Bioaugmentation using the white rot fungus Phanerochaete chrysosporium was found to be effective in enhancing TNT removal in lightly (i.e., below 100 mg/kg) contaminated soil. The percent reduction in TNT increased from 15% to 53% when soils were treated with fungal inoculated organic material. Maximum removal rates improved from 0.33 mg TNT/kg-day to 0.76 mg TNT/kg-day during the same treatment. Neither fungal inoculation nor organic amendment addition resulted in improving TNT removal kinetics in highly contaminated soils (i.e., above 1000 mg/kg). Executive Summary: Laboratory scale compost studies were conducted to evaluate the effect of bioaugmentation with the white rot fungus,
