Housing Age Profile
Lead solder was federally prohibited in new plumbing in 1986. In Fort Hall, the median build year of 1995 puts a majority of homes in the lower-risk category for that specific contamination pathway — though the pre-1986 share shown above still carries real exposure potential at the individual household level.
Most homes in Fort Hall were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.
