Newport Coast: Lead Risk & Vulnerable Populations

8%
Homes Built Before 1986

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.

Averaged across Newport Coast ZIP codes, the 90th-percentile lead results reported by water systems come to less than 10 parts per billion. That is an area summary rather than a reading from any home, and EPA's health goal for lead in drinking water is zero; about 8% of local housing predates 1986.

The $500 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
