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 Grandfield, where the median build year is 1961, 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.

Over half of homes in Grandfield 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.

Wherever 72% of local housing was built before solder rules changed - as is the case in Grandfield - a faucet-level sample closes the gap that aggregate utility data cannot.
