Avondale: Remediation Cost in Perspective

Median Home Value
$524,700
Est. Remediation
$4,300
Remediation as % of home value 0.8%

Remediation costs in Avondale are relatively low compared to home values. The $3,000–$6,300 estimated range is a small fraction of median property value. Home values are 146% above the Pennsylvania average.

Protecting Children from Lead in Avondale

30%
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.

Locally, Avondale's indicators line up: aggregate readings pass under the regulatory benchmark and the pre-rule housing footprint at 30% keeps lead in a background position.
