2021 Lead and Copper Tap Sampling Program

To comply with the Environmental Protection Agency’s (EPA) Lead and Copper Rule, the Alameda County Water District (ACWD) works with select customers to collect samples from qualifying drinking water sampling sites every three years. These sites are home faucets or other locations that may contain both lead and copper piping. The drinking water leaving ACWD’s treatment facilities contain no detectable lead or copper, but minute amounts of these contaminants may dissolve from the metal content in household plumbing. ACWD chose all participating sampling sites because they meet the EPA's criteria identified in the Lead and Copper Rule.


If you receive a letter in 2021, your property may still meet the selection criteria. Please fill out the form to determine if you are eligible to participate in this program. If you prefer, or if you have any questions, email program staff at TapSampling@acwd.com or call 510-668-6599.
