Housing Age Profile

If your home in Copperopolis predates 1986, testing the tap is the direct way to learn about lead; the median build year of 1991 cannot answer that for you.

Most homes in Copperopolis were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Copperopolis

mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

Several limits apply to the lead numbers for Copperopolis. The figure shown is an average of 90th-percentile results from ZIP codes in the city, and it is below 0.010 mg/L; the federal action level of 0.015 mg/L applies to each water system's own 90th percentile, not to an average like this one, and being below it does not make water free of lead. About 25% of local homes were built before 1986. A test at the home's own tap shows its level, and a filter certified to NSF/ANSI 53 for lead reduction is an option if a test finds lead.
