Indianapolis & Morgan County 2017 Water Quality Data

The chart below gives you a quick look at some of the substances that the EPA requires the utility to test for. You’ll notice that the contaminant is listed to the left, followed by the maximum amount allowed by regulations and then the amount that we found in our water. The tests are done on treated or “finished” water (excluding those listed under “Untreated Source Water”). See Definitions of Terms for an explaination of this chart.

Note: The state requires us to monitor for certain contaminants less than once per year because the concentrations of these contaminants do not change frequently.  Some of our data, though accurate, is more than one year old. Some contaminants are sampled less frequently than once a year; as a result, not all contaminants were sampled for during the CCR calendar year. If any of these contaminants were detected the last time they were sampled for, they are included in the table along with the date that the detection occurred. Compliance monitoring for lead and copper is required no less frequently than every 3 years. In an effort to be pro-active, Citizens conducts lead and copper sampling on an annual basis. Radiochemical contaminant monitoring is conducted every 9 years.

Lead note: Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that the lead levels at your home may be higher than other homes in your community as a result of materials used in your home’s plumbing. If you are concerned about elevated lead levels in your home’s water, you may wish to have your water tested. Also, flush your tap water for 30 seconds to two minutes before using tap water.
