How Old Is Dos Palos's Housing Stock?
With 68% 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
When a city's housing median build year is 1976, as in Dos Palos, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Dos Palos were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Dos Palos: Remediation Cost in Perspective
Because property values in Dos Palos comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Dos Palos are relatively low compared to home values. The $300–$1,500 estimated range is a small fraction of median property value. Home values are 60% below the California average.
Protecting Children from Lead in Dos Palos
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 68% of the Dos Palos 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.
