Key Contaminants Detected in King City
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is King City's Housing Stock?
With 49% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
What does a median build year of 1983 mean for water safety in King City? It means the housing stock straddles two key plumbing thresholds: the 1986 federal ban on lead solder in copper plumbing, and the pre-1970 era when lead pipes were commonly installed for service lines. A meaningful share of homes predates one or both of those cutoffs, creating varied risk levels across the city's housing inventory.
Most homes in King City were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

King City: Remediation Cost in Perspective
Placing remediation in the context of King City's property market, the equity share is low - most homeowners here are weighing a financial commitment that fits comfortably within routine property planning, far from the threshold where remediation becomes a material equity decision rather than a standard upkeep consideration.
Remediation costs in King City are relatively low compared to home values. The $1,200–$3,300 estimated range is a small fraction of median property value. Home values are 45% below the California average.
Protecting Children from Lead in King City
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.
Wherever 49% of local housing was built before solder rules changed - as is the case in King City - a faucet-level sample closes the gap that aggregate utility data cannot.

Historical Flood-Claim Evidence for King City
Historical NFIP data for King City contains 16 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $60,797. 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>$2,200</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.
