Likely Pipe Material

With 57% 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.

Housing Age Profile

Two dates define the high-risk tiers of residential plumbing from a lead standpoint: 1970, before which lead pipes were commonly installed for service connections, and 1986, before which lead solder was standard in copper plumbing. A median build year of 1970 places Chowchilla's housing distribution well within that older risk zone. The bar chart above breaks down how much of the stock falls into each era - and the pre-1986 share alone represents more than half the residential inventory, making plumbing-era risk a defining characteristic of the local water safety picture.

Over half of homes in Chowchilla were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Chowchilla

Setting Chowchilla remediation figures against its property market, the resulting ratio sits comfortably in the low tier - a classification that reflects the kind of household financial position where most homeowners can identify documented issues, schedule the work, and absorb the cost without it registering as a significant budget disruption.

Median Home Value
$342,000
Est. Remediation
$2,800
Remediation as % of home value 0.8%

Remediation costs in Chowchilla are relatively low compared to home values. The $1,600–$4,100 estimated range is a small fraction of median property value. Home values are 54% below the California average.

Chowchilla: Lead Risk & Vulnerable Populations

57%
Homes Built Before 1986

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 57% of local housing was built before solder rules changed - as is the case in Chowchilla - a faucet-level sample closes the gap that aggregate utility data cannot.

Chowchilla: NFIP Claim Records and Water-Quality Context

Total FEMA Flood Claims
100%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Chowchilla contains 1 flood insurance claim. 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>$2,800</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.
