Housing Age Profile
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Kwigillingok, the median build year of 1981 indicates that plumbing age is a material factor in local lead risk - with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
Most homes in Kwigillingok were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
