Key Contaminants Detected in Irvine
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Irvine's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
The story of Irvine's housing stock is one of layered development - neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 1998 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards - creating a risk environment that the city-wide aggregate water data doesn't fully capture.
Most homes in Irvine were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Irvine: Remediation Cost in Perspective
Across Irvine, the equity share taken up by estimated remediation is small - a favorable ratio for most property owners.
Remediation costs in Irvine are relatively low compared to home values. The $845–$2,009 estimated range is a small fraction of median property value. Home values are 42% above the California average.
Protecting Children from Lead in Irvine
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
When older housing represents 34% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Irvine address.

Historical Flood-Claim Evidence for Irvine
Historical NFIP data for Irvine contains 43 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $5,456. Among ZIP codes with claim records, 14% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The <strong>$1,318</strong> 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.
