Determination Of The Ecological Condition Of Benthic Communities Affected By Polycyclic Aromatic Hydrocarbons In The Elizabeth River, Chesapeake Bay, Usa, Adam M. Webb
Biological Sciences Theses & Dissertations
The Southern Branch of the Elizabeth River, a tributary of Chesapeake Bay, has historically been polluted with hydrocarbon based industrial by-products. My study compared benthic community condition from two locations in the Southern Branch: the subtidal region near Money Point, historically affected by pollution of polycyclic aromatic hydrocarbons (PAHs), to a subtidal region near Blows Creek on the opposite shore that is putatively designated as unimpacted by P AH contamination. Samples from both study sites in the Southern Branch were compared to the benthic community condition of samples from the same habitat type designations collected as part of the Chesapeake …
Assessing The Release Of Bioactive Trace Elements From Coal Fly Ash Into Natural Fresh Waters, Candace E. Wall
Assessing The Release Of Bioactive Trace Elements From Coal Fly Ash Into Natural Fresh Waters, Candace E. Wall
OES Theses and Dissertations
Each year a significant amount of coal fly ash enters the environment, where it can potentially cause adverse effects by releasing a range of bioactive trace elements. In this context, environmental studies have largely focused on the leaching of trace elements from the coal ash in landfills by rainwater and groundwater, while there has been relatively little study of the release of bioactive trace elements from coal fly ash deposited in natural fresh waters such as rivers and lakes. Furthermore, the batch leaching methods that have been used to study the interaction of rainwater and groundwater with coal ash in …
Fecal Indicator Bacteria In Knitting Mill Creek With A Comparison Of Methods Used To Enumerate E. Coli, Manju Nagarajan
Fecal Indicator Bacteria In Knitting Mill Creek With A Comparison Of Methods Used To Enumerate E. Coli, Manju Nagarajan
OES Theses and Dissertations
This research seeks to evaluate the impact of an urban, multi-use neighborhood on the bacteriological quality of water in Knitting Mill Creek, a blind arm of the Lafayette River, a sub-estuary of the lower Chesapeake Bay. A principal objective was to determine the effects of rainfall, a surrogate for run-off, on water-column concentrations of fecal-indicator bacteria (FIB). I collected water samples weekly (September 2009-December 2010) and biweekly (January 2010-December 2011) at a storm-sewer outfall and a nearby marina and quantified their E. coli and enterococci concentrations using Colilert-18 and Enterolert, most-probable-number assays. In addition, I took monthly samples for these …
The Pollution Effects Of Pleasure/Work Boat Sewage Discharges On Fecal Contamination Levels Of Waters In And Around Marinas And Other Places Where Boats Are Moored On The Eastern Shore Of Virginia, George H. Bangs
Community & Environmental Health Theses & Dissertations
Contamination of seafood harvested from and recreational areas of the Chesapeake Bay, its tributaries and the Atlantic coast inshore waters may cause health problems for people consuming the seafood or coming in contact with the waters by swimming, water skiing, or other water sports. These health problems include, but not limited to, dysentery, typhoid and hepatitis (Natchez, 1990). This is a preliminary study into the level of fecal pollution generated by sewage discharges from boats in marinas and other places where boats are moored on the Eastern Shore of Virginia. Sites selected for the study included; (I) marinas and other …
