Housing Age Profile

Federal plumbing rules changed in two stages - lead pipes were phased out before 1970, and lead solder was banned in 1986 - but in Charlo, where the median build year is 1971, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.

Lead Exposure Risk for Children in Charlo

62%
Homes Built Before 1986
0.002
mg/L Avg Lead (Limit: 0.015)

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.

Reading the local data together points toward a structural gap that matters more here than in low-exposure communities. 62% of Charlo stock comes from the pre-rule era, and citywide monitoring either approaches or sits beyond the federal benchmark under Lead and Copper Rule sampling. A baseline kit fits the routine-diligence category, with certified filtration available via retailer networks where confirmed faucet results warrant additional measures.
