Housing & Infrastructure in Crowheart
With 86% 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.

Housing Age Profile
Housing age is one of the most reliable proxies for plumbing-era lead risk, because two federal milestones — the widespread use of lead pipes before 1970 and the continued use of lead solder until 1986 — define the highest-risk tiers of the residential housing stock. With a median build year of 1942, Crowheart falls squarely within the older range — meaning a large fraction of the housing was built under the plumbing standards of those earlier eras. The distribution above captures where that risk concentrates, and why older neighborhoods warrant particular attention from residents concerned about tap water quality.
Over half of homes in Crowheart were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Lead Exposure Risk for Children in Crowheart
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.
Despite citywide averages serving as the standard public reference point, those aggregates cannot resolve what is happening at one specific faucet — and where 86% of Crowheart homes come from before the solder rule or where utility samples sit at or above the action mark, the gap between system data and faucet reality matters more than it does in lower-exposure communities. An in-home draw closes that gap, with certified filtration through retailer networks available where confirmed faucet results warrant additional measures.

What You Can Do in Crowheart
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 86% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. Your utility publishes an annual Consumer Confidence Report with detailed test results. Request it or find it online.
