Trihalomethanes are organic compounds formed in drinking water distribution systems as a result of disinfection. This capstone project researched and evaluated the statistical correlation of trihalomethanes in finished drinking water and total organic carbon in source water using data generated by Denver area utilities. Results of the study conclude that some drinking water supply systems show a slight correlation between source water total organic carbon levels and trihalomethane levels in finished water. Results of the study also verify the assertion that changes to treatment for the reduction of trihalomethanes, for the protection of human health under the Safe Drinking Water Act should be determined by each utility, using information from gathered data, seasonal trends, and small scale batch testing.
