indianola's water quality information

Each year IMU is required to inform our customers of the quality of water they are being provided.  This report, known as the Indianola Water Quality Report, is mandated by the Environmental Protection Agency under the Safe Drinking Water Act and provides information on Indianola’s drinking water system. 

Required information in this report includes the source from which IMU draws it's supply, any contaminants that may be found through annual/monthly testing, any contaminant violations, source water assessment information and any other additional health information that may be applicable to the individual water system.

Below are the sampling results for Indianola's drinking water system.  The state allows IMU to monitor for certain substances less than once per year because the concentrations of these substances do not change frequently.  In these cases, the most recent sample data are included, along with the year in which the sample was taken.
