Water quality management in a changing climate: A case study of 28 drinking water reservoirs and lakes in Colorado

DOM quality in Colorado lakes and reservoirs is strongly related to nutrient loading and algal production.  DOM composition impacts formation potential of carcinogenic chlorinated disinfection byproducts (DBPs).   Understanding the role specific phytoplankton species play in BDP production could provide targeted approaches for water utilities in maintaining storage water quality. Results from 28 lakes in CO show that Cyanobacteria may be a key phytoplankton species in this process.   Changes in climate such as longer summers, earlier ice-outs, and longer periods of ice-free conditions will have impacts on this finding.
