How Old Is Macdoel's Housing Stock?
With 80% 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
Heavily weighted toward older construction, Macdoel's housing stock carries a median build year of 1953. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Macdoel were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Macdoel: Remediation Cost in Perspective
At current valuations, Macdoel sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Macdoel are relatively low compared to home values. The $150–$600 estimated range is a small fraction of median property value. Home values are 81% below the California average.
Protecting Children from Lead in Macdoel
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.
When older housing represents 80% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Macdoel address.
