Likely Pipe Material

With 68% 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 Gap's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1975 reflects a city where lead-era plumbing materials are common rather than exceptional.

Over half of homes in Gap were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Gap Homeowners

In Gap, the equity impact of remediation is proportionally small — not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.

Median Home Value
$297,700
Est. Remediation
$2,400
Remediation as % of home value 0.8%

Remediation costs in Gap are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 40% above the Pennsylvania average.

Lead Exposure Risk for Children in Gap

68%
Homes Built Before 1986

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.

Routinely in Gap, where 68% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
