How Old Is Shafter's Housing Stock?
With 50% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Shafter's median build year of 1984 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Shafter were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Shafter: Remediation Cost in Perspective
Across Shafter, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Shafter are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 59% below the California average.
Protecting Children from Lead in Shafter
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 50% pre-rule share in Shafter keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
