Key Contaminants Detected in Rancho Cordova
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Rancho Cordova'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
1987 is the median build year in Rancho Cordova, and the age breakdown below shows how much of the housing predates 1986.
Most homes in Rancho Cordova were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Rancho Cordova: Remediation Cost in Perspective
Because the median home value in Rancho Cordova is large relative to the estimated cost of remediation, the ratio between them stays at or below 1%; that is a statement about two area-level numbers, not a quote for a particular house or a judgment about what an owner can pay.
Estimated remediation costs in Rancho Cordova can be compared with local home values. The $275–$700 estimated range can be set against the median property value; actual costs vary by home. Home values are 17% below the California average.
Protecting Children from Lead in Rancho Cordova
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.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical Flood-Claim Evidence for Rancho Cordova
Historical NFIP data for Rancho Cordova contains 5 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $2,304. Among ZIP codes with claim records, 0% 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 $450 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.
