The Denver Department of Public Health and Environment has warned that the water quality contamination could be due to high temperatures and storm water runoff
Water quality testing by the Denver Department of Public Health and Environment (DDPHE) revealed higher than normal levels of bacteria, including E. coli, in the South Platte River and tributaries. A water quality warning is in effect until further notice.
The 2018 Water Quality Report found that most Denver streams are not suitable for swimming currently, as reported by Fox Denver. The DDPHE attributes the contamination to recent high temperature that promote the growth of bacteria and contaminated storm water runoff.
“This river receives runoff from roads and streets, it gets discharges from wastewater treatment plants,” said Jon Novick of the DDPHE. “You could be at risk of making yourself sick.”
DDPHE offers an online map that shows updated water quality conditions.
