How Old Is Dolton's Housing Stock?
With 92% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Because the majority of Dolton's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1965 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Dolton were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Protecting Children from Lead in Dolton

When older housing represents 92% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Dolton address.
