Key Contaminants Detected in Clovis
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Clovis'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
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1990 places Clovis in the middle zone between those thresholds - with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
Most homes in Clovis were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Clovis: Remediation Cost in Perspective
When estimated remediation is placed alongside median property values in Clovis, the resulting ratio is low - a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Clovis are relatively low compared to home values. The $1,050–$3,350 estimated range is a small fraction of median property value. Home values are 38% below the California average.
Protecting Children from Lead in Clovis
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 40% of the Clovis inventory comes from before the federal ban on lead-bearing solder - and if utility samples sit at or near 0.015 mg/L - the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Historical Flood-Claim Evidence for Clovis
Historical NFIP data for Clovis contains 51 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $13,097. 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>$2,050</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.
Source: historical FEMA National Flood Insurance Program (NFIP) claim records. No current FEMA property-map designation is asserted.
What You Can Do in Clovis
- Test your water at home. City-level data shows averages - your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. Filters rated for Lead can reduce the most common contaminant found in Clovis's water.
- Check your home's plumbing. With 40% of homes built before 1986, lead solder is a real possibility.
