Housing Age Profile
Although a small portion of Saint Bonifacius's homes predate 1986, the median build year of 1992 indicates the majority of the city's residential plumbing was installed after lead solder was banned — which tends to reduce the plumbing-related component of lead exposure at the household level.
Most homes in Saint Bonifacius were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Saint Bonifacius
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.
Reading Saint Bonifacius's aggregate samples next to its housing-age figures yields a quiet baseline. Lead rests under the federal action benchmark in citywide monitoring, and only 28% of homes were built before the federal ban on solder containing lead. Households with kids — the population for whom CDC guidance places particular weight on minimizing exposure — can confirm in-home conditions with a draw-test kit, with a certified lead-removal filter available through certified retail channels if results warrant it.
