Housing Age Profile
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Eagle Butte's median build year of 1971 places it squarely in that category.
Over half of homes in Eagle Butte were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Eagle Butte: Remediation Cost in Perspective
In Eagle Butte, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.

Protecting Children from Lead in Eagle Butte
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.
When older housing represents 60% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Eagle Butte address.
