Westfield - South Madison (IN5248026) 2025 Water Quality Data
The chart below gives you a quick look at some of the substances that the EPA requires Citizens to test for. The contaminant is listed to the left, followed by the maximum amount allowed by regulations, then the amount that we found in our water. The tests are done on treated finished water. See Definitions of Terms for an explanation of terms used in this chart.

SECONDARY DRINKING WATER STANDARDS
|

* Secondary standards are non-mandatory guidelines established by the EPA to assist utilities in managing drinking water for aesthetic considerations, such as taste, odor, and color. These contaminants are not considered to present a risk to human health at the SMCL. |

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 2025 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 three years. Radiochemical contaminant monitoring is conducted every nine years.
