The Effects of Climate Change on Algae in the Denver Metro Area's Drinking Water Reservoirs

Six Denver metro water reservoirs were sampled to see what types of algae were found, and what impact the algae would have on drinking water reservoirs in the event of a bloom caused by warming water temperatures. Each sample contained algae. Toxic cyanobacteria, filamentous green algae, and different species of diatoms were found in the samples. Current climate change models show the temperature along the Front Range is rising and will continue to rise. With an increase in climate change and an increase in population, humans and animals will be at a greater risk of ingesting or coming into contact with toxic algae.

Management of Trihalomethanes in Finished Drinking Water Through Source Water Precursor Monitoring

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.
