Additionally, the Water Department’s corrosion control program functions to reduce corrosion of the metal piping water travels through by raising the naturally corrosive pH of area groundwater to a slightly alkaline and non-corrosive level. This program has been effective at reducing lead concentrations in the drinking water.
When your water has been sitting for several hours (such as overnight), you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using the water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline at 800-426-4791 or at
