Kaweah Infrastructure Age
With 48% 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
Housing age is a practical proxy for plumbing risk because federal standards changed in 1986, when lead solder was banned from new residential construction, and again earlier — before 1970, lead pipes were themselves commonly installed. Kaweah's median build year of 1982 sits in the range where both pre- and post-1986 homes are well represented. The bar chart above reflects that mixed picture: the distribution captures pockets of older housing alongside more recent development, and those pockets carry real lead risk potential at the individual property level.
Most homes in Kaweah were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Kaweah
At current valuations, Kaweah sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.

Kaweah: Lead Risk & Vulnerable Populations
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted — but 48% of the Kaweah inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.
