Abstract

The operation of a former battery processing facility from 1963<br>thru 1980 resulted in surface soil contamination of eighty homes<br>and nearby drainageways. Engineering plans were developed to<br>remove lead contaminated soil from the residential areas. The<br>plans defined area1 removal limits and depths based on a 500 parts<br>per million action level.<br>Soil removal plans were developed on a block by block basis.<br>Preliminary removal limits were established using the soil sampling<br>results performed an extent of contamination study. Removal limits<br>were verified with additional sampling prior to excavation.<br>Excavation sequences and methods were developed by the contractor<br>and engineers prior to removal activities to minimize unnecessary<br>inconveniences for the residents. Confirmatory samples taken after<br>the designed removal of contaminated soil were used to indicate the<br>need for additional excavation or the beginning of restoration.<br>A community relations program was instituted to provide residents<br>with a communication link to the client and engineers. The<br>community relations program promoted an atmosphere of open<br>communication which helped lead to a successful completion of the -<br>project. Periodic meetings between the residents and engineers<br>were set up during various project phases. These meetings often<br>provided valuable information explaining contamination patterns and<br>also allowed residents to express concerns and/or problems. This<br>program gave the residents a first hand knowledge of the project<br>and helped alleviate concern and worry.<br>This case history documents the procedures used to safely remove<br>lead contaminated soil from a residential area. Problems arising<br>from the removal action and restoration of properties were handled<br>on an individual basis. The open communications between the<br>engineers, the regulatory agency, and the residents resulted in a<br>successful remediation project.
