Housing Age Profile

Why does housing age matter for water safety? Homes built before 1986 may have lead-soldered copper plumbing joints - a practice banned that year. Castroville's median build year of 1992 places much of the city's housing in the post-ban era, reducing that specific risk pathway for most residents.

Most homes in Castroville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Castroville: Lead Risk & Vulnerable Populations

28%
Homes Built Before 1986
0.0046
mg/L Avg Lead (Limit: 0.015)

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.

Where pre-rule stock represents a smaller fraction of the inventory - 28% across Castroville - the structural drivers of household exposure run thinner. Aggregate readings under the federal benchmark reinforce that picture, with one-home draws remaining the only direct measurement for a specific address.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Castroville contains 34 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $50,854.

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>$1,800</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.
