Logan Section Contamination
EPA Region 3 (Mid-Atlantic)
EPA ID# PASFN0305530
1st Congressional District
Last Update: October
Current Site Status
The Memorandum of Agreement with the City of Philadelphia was closed on September 30, 2002, with the City demonstrating satisfactorily that it had performed and completed the actions agreed to in the Agreement.
The site comprises a 17-block area in the Logan section of Philadelphia, bordered by Roosevelt Boulevard on the southeast, by Marshall Street on the east, by Wingohocking Street on the south, by 11th Street on the west and by Loudon Street on the north. The site is located in a former stream valley which was filled with coal cinder and ash prior to the construction of houses in the early part of the 20th century. Over time, the ash fill has settled or eroded, leaving the houses on increasingly unstable foundations. By 1986, the City determined that many houses and other structures were unsafe and began evacuating homes and other structures determined to be in imminent danger of collapse. Beginning in 1986, the City initiated the demolition of houses.

Threats and Contaminants
From November 8 through November 10, 1999, EPA collected 230 grab samples from the surface soils at the site. Results from this sampling revealed lead levels ranging from 25 ppm to 22,300 ppm. The average lead levels in soil in six areas of the site were determined to pose potentially unacceptable risks to young children under a residential exposure scenario.
The City has excavated and properly disposed of the top 12 inches of soil from the areas designated in the Agreement and backfilled the excavated areas with clean fill material. The affected areas of the site will be seeded and revegetated during this Spring.
