Bunker Hill Infrastructure Age
With 71% 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 Bunker Hill's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1978 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Bunker Hill were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Bunker Hill

Bunker Hill: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 71% pre-rule share in Bunker Hill keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
