Housing Age Profile

For residents trying to assess tap water risk in Afton, the median build year of 1983 is the starting context. It signals that a majority of homes were constructed before 1986 - the year federal rules prohibited lead solder in new plumbing - and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.

Protecting Children from Lead in Afton

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.

Before the federal solder ban, lead solder was a routine plumbing material, and 50% of the Afton inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.
