Recent events in Flint, Michigan, have people across the country asking questions about lead in drinking water. Could it happen here? It is very unlikely, for several reasons:
Senior Environmental Chemist Connie Sanchez tests water samples on an instrument that can detect contaminants to the level of a few parts per trillion. DSRSD's lab uses this instrument to test tap water samples for lead and copper.
- Flint has thousands of lead water pipes and old plumbing fixtures. DSRSD has never used lead pipes in its distribution system.
- Flint changed its water source, which altered the water’s pH balance. As a result, their water became extremely corrosive and the city did not implement a corrosion-control program. Here, Zone 7 Water Agency adjusts the pH of our water to make it as non-corrosive as possible. Approved by the state’s Division of Drinking Water, Zone 7‘s corrosion-control program has been working effectively for decades, and there has been no significant change in our water supply since corrosion control began.
- DSRSD and Zone 7 regularly test the water in accordance with all state and federal requirements to ensure it is safe to drink.
