The Historical Analysis of the Ion Content of Water in the Washita Zone of Lake Texoma, Oklahoma, USA

Rich-Sawka, Alisa. The Historical Analysis of the Ion Content of Water in the Washita Zone of Lake Texoma, Oklahoma, USA. Master of Public Health (Environmental and Occupational Science), November, 2004, pages, 7 tables, 6 figures, 30 references. The primary objective of this study was to analyze the conductivity and ionic content of water in the Washita River Zone of Lake Texoma, for the study period of 1996-1997. The ionic concentrations of calcium, sodium, chloride, sulfate and bromide were determined and then compared with conductivity with analysis of ratio of CI/Br, Na/CI, Na+C1)/TDS to validate the presence of anthropogenic source contamination from oil field brine after review of recommended values in the literature. A geologic review of the watershed was performed to confirm the underlying geologic formation was not a contributing factor. Due to a lack of consistent reliable data during the study period, a historical database was built and statistical analysis was performed confirming through bromide ratios a preexisting anthropogenic source contamination of the Washita River watershed.
