The Wilmette Water Quality Laboratory objectives are to ensure compliance with the Safe Drinking Water Act (SDWA) and the drinking water quality meets the highest standards.
The Safe Drinking Water Act (SDWA) is the federal law that protects public drinking water supplies throughout the nation. Under the SDWA, the US EPA sets standards for particular contaminants in drinking water. Water supply systems must test for these contaminants and, if necessary, the water is treated to reduce contaminants to the maximum contaminant levels (MCLs) set for each contaminant.
The laboratory must test these water quality parameters, at different intervals, established by the Illinois EPA and US EPA to protect public health. Also, the detected contaminants must be published in our annual water quality report, the Consumer Confidence Report (CCR). Read the current CCR HERE.
Examples of the water quality testing and the frequency performed by our laboratory is listed below:
Additionally, our laboratory is certified by the Illinois Department of Public Health (IDPH) to analyze water for bacteriological contamination. IDPH inspectors audit the laboratory every two years. The audit consists of an onsite evaluation in which procedures, records, and equipment are inspected. Over 200 different criteria must be met in order to be in perfect compliance with Zero Deviations.
If you have any questions regarding the water quality, please contact Stefanie Ladao at (847) 853-7532 or email@example.com.
