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 1968, Sigourney 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 Sigourney were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Sigourney: Lead Risk & Vulnerable Populations

Homes Built Before 1986
0.0019
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.

Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 81% of Sigourney 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.
