Housing & Infrastructure in Helena
With 88% 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
Plumbing risk in older housing is tied to the period before 1986, when lead pipes and lead solder were still permitted in new plumbing. Helena's median build year is 1966, and properties from before that year might still contain lead-bearing joints or pipes. Much of that risk sits inside individual properties, which city-level water quality averages don't capture.
Over half of homes in Helena 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 Helena
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.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
