The City of Bloomington Utilities has reported an increase in customer complaints about temporary water discoloration linked to seasonal changes and heightened water levels in the Monroe Reservoir.

CBU regularly monitors these minerals and has made operational adjustments to improve water clarity, including enhanced hydrant flushing and monitoring throughout the system. All water samples collected remain well within EPA health advisory levels, ensuring the safety of the drinking water supply. Residents are encouraged to change their water filters more frequently until conditions normalize. This seasonal phenomenon highlights the importance of monitoring water quality, especially during periods of environmental change.
