The Texas Commission on Environmental Quality (“TCEQ”) requires all water systems to sample for the presence of lead. Residents of the West Gate and Paddock subdivisions in Harris County MUD 70 collected 20 samples during the period June 1- September 30, 2022, of which three samples exceeded the action level of .015 mg/L. The customers received notification of sample results during the same sample period. This first round of samples were all self-administered and collected by the residents from the internal faucets of their homes. There are specific state guidelines, and any deviation from these guidelines can alter the sample results. Once the customer collects the samples, a MUD representative takes those samples to a state certified lab for testing.
For the three samples that initially exceeded the action level (.015mg/L), representatives of MUD 70 visited those households to instruct them on the process for re-testing. In each case, the results from those three new tests were found to be below the action level.
Because of this, there is no indication of a problem with the public drinking water in Harris County MUD 70.
Nevertheless, in an abundance of caution, MUD 70 will ask residents to resample in January 2023. All customers in the MUD received information via USPS regarding lead public education the week of November 28th, 2022. This letter is meant to inform customers on lead material in their homes’ plumbing that could potentially leach into the water supply.
