Remediation of lead contaminated soil at Greenbury Point, Annapolis, Md

摘要

The remedial investigation is satisfied through compilation of information required to adequately characterize Greenbury Point. Information includes data on lead, applicable regulatory requirements, soils types, contamination, site maps, field investigations, utility drawings, history, archeology, and natural resources. The feasibility study is satisfied through examination of remedial options. Various treatment technologies are screened for effectiveness in reducing the lead contamination or risks associated with the lead contamination. These include in-situ technologies, such as containment, soil flushing, and electrokinetic treatment; ex-situ technologies, such as physical separation/ concentration, soil washing and pyrometallurgical separation; and technologies with both in- and ex-situ applications, such as cement based solidification/ stabilization, polymer microencapsulation solidification/ stabilization, and vitrification. Each of these technologies is described and compared to conditions at Greenbury Point
