April 2021 Test Results

As noted in our May 12 2021 meeting, an anonymous complaint was filed with the CA State Water Board about WHWD water quality. As a result, the district was forced to spend over $8,000 to do immediate sampling and testing of our treated water, in addition to the regular weekly testing we already perform. Below is the complaint response from the water board to WHWD, as well as the water reports and invoices resulting from our compliance with the water board's requests. All reports showed full compliance with state and federal regulations and requirements.

If you have any questions about the quality of your water at your home, please do not hesitate to contact our office at 209-895-9493. We are here to serve you, fellow residents of DG, and here to help determine if there is a piping problem or some other issue affecting your water quality. We would very much like to avoid these additional testing costs in the future.
