Westfield - South Madison (IN5248026) 2024 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 and 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 & UNREGULATED CONTAMINANTS:
|

|
* 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. |

| Chloride (ppm) | 250 ppm | 31 ppm | 46 ppm | 24 - 46 ppm | Natural deposits; water treatment additive | ||
| Hardness (ppm) | N/A | 415 ppm 24 grains/gal |

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 2024 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.
Note about Lead in Tap Water: 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. Additional information is available from the U.S. EPA Safe Drinking Water Hotline at 800-426-4791 or www.EPA.gov
Citizens participated in the Indiana Department of Environmental Management (IDEM) voluntary monitoring program for PFAS compounds. Citizens collected samples from source and finished water in June 2022 and detected compounds are shown in the table above. More information and full results can be found on IDEM’s website at in.gov/idem/pfas/.
