Key Contaminants Detected in Underwood

How Old Is Underwood's Housing Stock?
With 45% 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
Because Underwood's housing stock spans a wide range of construction eras, the median build year of 1981 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 Underwood were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Underwood: Remediation Cost in Perspective
Equity impact data for Underwood lands in the favorable tier - remediation claims a small slice of what properties here are worth.
Remediation costs in Underwood are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 22% above the Washington average.
Protecting Children from Lead in Underwood
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Underwood have approached or crossed the regulatory action level on multiple occasions. Combined with 45% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
