Housing Age Profile
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1998 places Navajo Dam in the middle zone between those thresholds — with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
Most homes in Navajo Dam were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Both the housing inventory and the system data support active household-level reads as a practical step.
