Release Of Vocs, Gasses, And Bacteria From Contaminated Landings And Creeks Of Ogeechee River Basin, Victoria A. Clower, Melanie Sparrow, Atin Adhikari Aug 2022

Release Of Vocs, Gasses, And Bacteria From Contaminated Landings And Creeks Of Ogeechee River Basin, Victoria A. Clower, Melanie Sparrow, Atin Adhikari

Department of Biostatistics, Epidemiology, and Environmental Health Sciences Faculty Publications

River landings are common public grounds, visited by many people every day. The aftermath of visiting these places may be unsettling since much trash is left behind and scattered throughout. The litter collects and with each rain or high wind, it has a better chance of ending up in our streams, rivers, creeks, and eventually our oceans. The main purpose of this study was to measure both air and water quality throughout the Ogeechee River basin in South Georgia to determine how each was impacted by trash. Ammonia, methane, and volatile organic compounds (VOCs) along with temperature and humidity were …


The Effectiveness Of Best Management Practices Implemented At Lake Gregory, Crestline, Ca, Devin Darrow May 2022

The Effectiveness Of Best Management Practices Implemented At Lake Gregory, Crestline, Ca, Devin Darrow

Electronic Theses, Projects, and Dissertations

Water quality deterioration of recreational surface waters from excess pollution inputs is a significant concern for the health of the public and aquatic ecosystem. This study will examine the effectiveness of Best Management Practices (BMPs) in reducing pollution inputs into Lake Gregory, Crestline, CA. The effectiveness of the BMPs was examined by testing for water quality parameters including dissolved oxygen, temperature, pH, conductivity, turbidity, nitrate (NO3-), ammonium (NH4+), total coliform, and Escherichia coli on weekly to bi-weekly basis for a period of 1 year. A statistical analysis involving descriptive statistics, Pearson’s correlation, the Efficient Ratios (ER) and Percent Removal Rates …


Environmental And Community Health In South San Diego County: A Behavior Analysis Of Recreational Ocean Users Along Imperial Beach, California, Trista Brophy Jun 2016

Environmental And Community Health In South San Diego County: A Behavior Analysis Of Recreational Ocean Users Along Imperial Beach, California, Trista Brophy

USF Tampa Graduate Theses and Dissertations

Garbage & sewage runoff into the Pacific Ocean at the shoreline along the U.S./Mexico Border region poses serious health and environmental threats. The purpose of this study was to analyze the current beach users’ behavioral factors that may be linked to illness prevalence from Coronado Island to the U.S./Mexico border at Imperial Beach in San Diego County. It is a continuation of a study completed by Wildcoast and Imperial Beach Clinic in 2011. The study tried to answer the following two major questions: How have the number of illnesses reported by users along South San Diego County beaches changed in …


The Evaluation Of Water Quality And Weather Patterns As Indicators For Escherichia Coli In Slaters Creek Watershed In Millersville, Tennessee, Jacqueline Brown May 2012

The Evaluation Of Water Quality And Weather Patterns As Indicators For Escherichia Coli In Slaters Creek Watershed In Millersville, Tennessee, Jacqueline Brown

Mahurin Honors College Capstone Experience/Thesis Projects

Water quality sampling was conducted in conjunction with the city of Millersville, Tennessee in order to assess levels of Escherichia coli (E. coli) in Slaters Creek. The city of Millersville is under a storm water National Pollutant Discharge Elimination System (NPDES) permit that requires compliance monitoring. In the past, monitoring of E. coli has resulted in noncompliance with state water quality regulations. A water quality assessment, including E. coli and water quality parameters, was conducted to determine if E. coli levels varied between dates within the study area. Statistical methods were utilized to determine if variations existed between the sampling …


Metal-Resistance Genetically Engineered Bacteria, Sylvia Daunert, Donna Scott, Sridhar Ramanathan Jun 1996

Metal-Resistance Genetically Engineered Bacteria, Sylvia Daunert, Donna Scott, Sridhar Ramanathan

KWRRI Research Reports

Bacterial-based electrochemical and optical sensing systems that respond in a highly selective and sensitive manner to antimonite and arsenite have been developed. This was accomplished by using genetically engineered bacteria bearing one of two plasmids constructed for our studies. The first plasmid, pBGD23, contains the operator/promoter region (O/P) and the gene of the ArsR protein from the ars operon upstream from the β-galactosidase gene. In the absence of antimonite/arsenite, ArsR binds to the 0/P site and prevents the transcription of the genes for ArsR and β-galactosidase, thus blocking expression of these proteins. When antimonite or arsenite is present in the …

The Aquatic Toxicity Of Organic Compounds To Embryo-Larval Stages Of Fish And Amphibians, Jeffrey A. Black, Wesley J. Birge, Willaim E. Mcdonnell, Albert G. Westerman, Barbara A. Ramey, Donald M. Bruser Mar 1982

The Aquatic Toxicity Of Organic Compounds To Embryo-Larval Stages Of Fish And Amphibians, Jeffrey A. Black, Wesley J. Birge, Willaim E. Mcdonnell, Albert G. Westerman, Barbara A. Ramey, Donald M. Bruser

KWRRI Research Reports

Aquatic toxicity tests were conducted on 11 organic compounds considered hazardous to water resources. The toxicity of each compound was evaluated using embryo-larval stages of two to eight fish and amphibian species. Exposure was initiated at fertilization and maintained through 4 days posthatching. The animal test species exhibited varying degrees of sensitivity to the selected toxicants. Combined frequencies for mortality and teratogenesis at 4 days posthatching gave LC50 ranges of 3.66 to 8.25 mg/L for benzene, 1.16 to 22.42 mg/L for carbon tetrachloride, 0.11 to 1.20 mg/L for chlorobenzene, 2.03 to > 68 mg/L for chloroform, 3.01 to 5.56 mg/L …

Effects Of Organic Compounds On Amphibian Reproduction, Wesley J. Birge, Jeffrey A. Black, Robert A. Kuehne Jan 1980

Effects Of Organic Compounds On Amphibian Reproduction, Wesley J. Birge, Jeffrey A. Black, Robert A. Kuehne

KWRRI Research Reports

Aquatic toxicity tests were conducted with atrazine, carbon tetrachloride, chloroform, methylene chloride, trisodium nitrilotriacetic acid (NTA), and phenol. Each compound was administered to developmental stages of three to five amphibian species. Exposure was initiated at fertilization and maintained through 4 days posthatching. Test responses included lethality and teratogenesis. Different amphibian species exhibited varying degrees of tolerance to the selected compounds. Greatest tolerance usually was observed for the more broadly adapted semi-aquatic and terrestrial species (e.g., Bufo americanus, Bufo fowleri). The more sensitive amphibians usually included those species which normally are restricted to aquatic or moist habitats (e.g., Rana …
