Housing & Infrastructure in West Salem
With 51% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Lead can reach tap water from service lines, solder and brass fittings inside a building, which is why housing age draws attention in West Salem, where the median build year is 1985.
Over half of homes in West Salem were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Lead Exposure Risk for Children in West Salem
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Two pieces of area data frame lead for West Salem families. First, the average of ZIP-level 90th-percentile lead results is 0.010 mg/L or higher. Second, census figures put homes built before 1986, which are more likely to contain lead pipes, fixtures or solder, at about 51% of the housing stock. Neither figure measures a particular home, so a certified lab test of the tap water is the step that shows the lead level there.
