Housing Age Profile

Plumbing risk in older housing is defined by two eras: the pre-1970 period when lead pipes were commonly used for service lines, and the 1970-to-1986 period when lead solder remained standard in copper plumbing until the federal ban. Avon's median build year of 1942 lands in a range where both eras are heavily represented in the housing stock. That creates an elevated aggregate environment for plumbing-related lead exposure - one that city-level water quality averages don't capture, because the risk sits inside individual properties rather than in the distribution system.

Over half of homes in Avon were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

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 84% of Avon 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.
