Unfortunately this is a system wide issue we're experiencing. The warm and dry weather this month has resulted in an increase in algae from Lake Monroe producing geosmin and methylisoborneol (MIB), which cause taste and odor issues with the drinking water. Our treatment system is able to control and filter the algae itself, but the compounds they produce in the lake are very difficult to control in a conventional water treatment plant, and so at times they persist after treatment. These compounds are not a health concern, they are an aesthetic issue which is not uncommon for communities using lakes as their water source. There are certain steps we're taking to try to eliminate the issue, such as increasing the amount of powdered activated carbon and copper sulfate that we add to the water to control algae and help with taste and odor issues. However we do not want to add more chemicals to our water than is absolutely necessary so this is a slow and methodical process. As the weather cools down the algae will return to normal levels. We’re continually testing the water for many different quality parameters in multiple sites in our distribution system and at our water treatment plant to ensure the water continues to be safe to drink. Unfortunately it may take some time before we return to the normal water taste and absence of odor, but we are working to correct the issue. I apologize for this inconvenience. You are welcome to call or email with any questions. Tyler Steury City of Bloomington Utilities Water Quality Coordinator steuryt@bloomington.in.gov (812) 349-3655 office (812) 361-7774 cell
