Coliform/Microbial Sample Results

To develop and maintain a record of water quality, it is necessary to collect representative samples of the water and have them analyzed by a certified laboratory on a routine basis. Sampling, combined with proper operation, operational testing and record keeping with periodic facility inspection, is an effective means of documenting the safety and quality of the water reaching the consumer.

The EPA requires treated tap water to have a detectable level of chlorine to help prevent contamination. The allowable chlorine levels in drinking water (up to 3.99 mg/L) pose “no known or expected health risk [including] an adequate margin of safety.”
