Housing Age Profile
What does a median build year of 1968 mean for water safety in East Northport? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used - making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in East Northport were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.
