Water Quality

Every day, Louisville Water Company conducts hundreds of tests in its Environmental Protection Agency (EPA) certified laboratory to ensure the quality and safety of our drinking water.

We produce the Annual Water Quality Report (PDF) to inform customers about testing results and the quality of their drinking water. This annual water quality report, also called the Consumer Confidence Report, is prepared in accordance with the EPA’s Safe Drinking Water Act Amendment. Our tap water surpasses the EPA’s strict health standards and it tastes so good we gave it a name – Louisville pure tap®. This report is mailed to our customers every year by July 1.
