Housing Age Profile
Because Shandon's housing stock spans a wide range of construction eras, the median build year of 1982 lands in a zone where two distinct risk populations share the same residential market. Homes built before 1986 may have lead-soldered copper plumbing joints - that practice was federally prohibited in 1986 but remained standard until then. The fraction built before 1970 face an additional risk: lead pipes used for service line connections were common before that decade, meaning both the pipe and the solder may be lead-containing in the oldest structures. Residents in mid-century or earlier homes face a different risk environment than neighbors in houses built after 1986, even if they drink from the same utility's supply - and that property-level divergence is what makes the age distribution above more diagnostic than the city-wide median alone.
Most homes in Shandon were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

In recent monitoring under the Lead and Copper Rule, citywide samples for Shandon have approached or crossed the regulatory action level on multiple occasions. Combined with 46% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
