Because the majority of Wanblee's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1984 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Wanblee were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.
