Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Imperial'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 median build year for Imperial is 1992. A build year alone does not tell you what pipes or solder a home has.
Most homes in Imperial were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Imperial: Remediation Cost in Perspective
Low tier for Imperial: remediation estimated at up to 1% of what homes are worth.
Estimated remediation costs in Imperial can be compared with local home values. The $150–$600 estimated range can be set against the median property value; actual costs vary by home. Home values are 53% below the California average.
Protecting Children from Lead in Imperial
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.
A tap test is the direct way to learn the lead level in a given Imperial home; 28% of local housing predates 1986.

Historical Flood-Claim Evidence for Imperial
Historical NFIP data for Imperial contains 6 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $4,996. Among ZIP codes with claim records, 100% 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 $300 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.
