Niangua Infrastructure Age

Housing Age Profile
The median home in Niangua was built in 1987 — a figure that places most of the city's residential stock in the era when lead solder was still standard in copper plumbing. Homes built before 1986 may have lead-soldered joints; those built before 1970 face the additional possibility of lead pipes in the service line itself.
Over half of homes in Niangua were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Niangua
In Niangua, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Niangua are relatively low compared to home values. The $150–$1,400 estimated range is a small fraction of median property value. Home values are 8% above the Missouri average.
Niangua: Lead Risk & Vulnerable Populations
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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 55% of Niangua stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.
