How Old Is Hazleton's Housing Stock?
With 76% 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
Plumbing risk in older housing is defined by two eras: the pre-1970 period when lead pipes were commonly used for service lines, and the 1970-to-1986 period when lead solder remained standard in copper plumbing until the federal ban. Hazleton's median build year of 1975 lands in a range where both eras are heavily represented in the housing stock. That creates an elevated aggregate environment for plumbing-related lead exposure — one that city-level water quality averages don't capture, because the risk sits inside individual properties rather than in the distribution system.
Over half of homes in Hazleton were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Hazleton: Remediation Cost in Perspective
Across Hazleton, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Hazleton are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 3% below the Iowa average.
Protecting Children from Lead in Hazleton
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Hazleton have approached or crossed the regulatory action level on multiple occasions. Combined with 76% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
