Key Contaminants Detected in Imperial
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 home in Imperial was built in 1992, after the federal ban on lead solder in plumbing. Most of the housing stock postdates that cutoff, placing typical plumbing risk on the lower end - though any home built before 1986 still warrants individual testing.
Most homes in Imperial were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Imperial: Remediation Cost in Perspective
Given current Imperial valuations, the remediation-to-property-value ratio is low - most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Imperial are relatively low compared to home values. The $950–$2,400 estimated range is a small fraction of median property value. Home values are 53% below the California average.
Protecting Children from Lead in Imperial
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.
If aggregate samples sit below the EPA action level and just 28% of Imperial's inventory comes from the pre-rule era, systemic lead is not a dominant local concern. The aggregate still cannot tell a homeowner what is actually flowing from a specific faucet on a specific morning, which is why an in-home draw exists as a separate measurement at the household tier.

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 <strong>$1,500</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.
