Ducor Infrastructure Age
With 73% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Ducor's median build year of 1976 places it squarely in that category.
Over half of homes in Ducor were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Ducor
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Ducor is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Ducor are relatively low compared to home values. The $150–$1,400 estimated range is a small fraction of median property value. Home values are 76% below the California average.
Ducor: 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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 73% pre-rule share in Ducor keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
