Remediation Of Risks In Natural Gas Storage Produced Waters: The Potential Use Of Constructed Wetland Treatment Systems, Brenda Johnson Dec 2006

Remediation Of Risks In Natural Gas Storage Produced Waters: The Potential Use Of Constructed Wetland Treatment Systems, Brenda Johnson

All Theses

Natural gas storage produced waters (NGSPWs) are generated in large volumes, vary in composition, and often contain constituents in concentrations and forms that are toxic to receiving system biota. This research had three major objectives: 1) Characterize NGSPWs to discern the constituents of concern present in these waters; 2) Design and measure performance of a pilot-scale hybrid constructed wetland treatments system (CWTS) for treating NGSPWs, and; 3) Discern the reliability of the Turner Designs TD500 handheld fluorometer for measurement of oil-in-water in produced waters containing algae. Produced waters contained chlorides, metals, and organics as constituents of concern. Using simulated produced …


Occurrence And Control Of Large Patch (Rhizoctonia Solani Ag 2`2 «Lp«On Seashore Paspalum (Paspalum Vaginatum O. Swartz) In South Carolina, Alejandro Canegallo Dec 2006

Occurrence And Control Of Large Patch (Rhizoctonia Solani Ag 2`2 «Lp«On Seashore Paspalum (Paspalum Vaginatum O. Swartz) In South Carolina, Alejandro Canegallo

All Theses

Seashore paspalum is a new turfgrass being evaluated in the southeastern United States due to its tolerance to salinity and sodicity. Rhizoctonia solani AG 2-2 `LP` was isolated from seashore paspalum exhibiting symptoms typical of Large Patch (LP). The disease was identified based on field symptoms, lesions on the plant, and the fungus identified based on cultural characteristics, multinucleate hyphal cells, and anastomosis with a known tester isolate of R. solani AG 2-2 `LP` from zoysia grass.
Two research putting greens were constructed in 2005 located in Florence, SC and near Bluffton, SC and planted to seashore paspalum cultivars SeaIsle …


Toxicological Effects Of Endocrine Disrupting Compounds In Bluegill, Pamela Truman Dec 2006

Toxicological Effects Of Endocrine Disrupting Compounds In Bluegill, Pamela Truman

All Theses

The water quality in the Reedy River basin has been shown to be impacted from the diverse and highly urbanized land uses within the watershed. The objective of this study was to examine the observed toxicological effects of EDCs that may be present in the Reedy River watershed by using a suite of biomarkers that were measured in indigenous fish to characterize the exposure and biological effects of these contaminants. Bluegill were analyzed for unnatural estrogenic effects such as: 1) Vitellogenin (VTG) 2) Activity of estrogenic compounds in bile extractions 3) UDP-glucuronosyltransferase (UGT) activity. This biomarker study provides a more …
