환경보호국(EPA)가 BFI 로킹엄 쓰레기매립지 슈퍼펀드 현장에 대해 현재 진행 중인 처리방안의 주요 추천 수정사항을 제안했다. 이는 현장의 지하수를 정화하기 위해 늘어난 기간과, 오염된 물에 노출되는 것을 예방하기 위해 추가된 지하수 제한, 비소와 납의 오염물질 때문에 변경된 정화단계를 모두 포함한다.

EPA는 개선책이 이 두 금속물질에 대한 주와 연방의 표준을 변화하는 데 기초해 인류의 건강과 환경을 보호한다는 것을 보장하기 위해 이러한 측정을 진행하고 있다.

 

 

EPA announces major modifications to ongoing VT landfill Superfund site remedy
    
The Environmental Protection Agency (EPA) has proposed major recommended modifications to the ongoing remedy of the BFI Rockingham Landfill Superfund Site (Site) in the city of Rockingham, Vt., that include an increased timeframe to cleanup Site groundwater, additional groundwater restrictions to prevent exposure to contaminated groundwater, and revised cleanup levels for two contaminants -- arsenic and lead.

 

EPA is carrying out these measures to ensure that the remedy remains protective of human health and the environment based on changes to the federal and state standards for these two metals. Further, the Agency will be accepting public comment on these recommended modifications from Sept. 11 to Sept. 25, 2014.

 

 The Site is a 17-acre landfill located along U.S. Route 5 and adjacent to the Connecticut River. From 1968 until 1991, the landfill received residential, commercial and industrial solid and liquid wastes. Approximately 1.2 million cubic yards of solid waste were disposed in the landfill during its operation. The majority of wastes were placed in unlined landfill cells. In October 1989, the Site was included on the EPA National Priorities List (NPL).

 

 The 1994 cleanup plan, also known as the Record of Decision, estimated that the groundwater restoration aspect of the cleanup would be complete in a 15-year timeframe. By the spring of 2009, however, long-term monitoring results indicated that Interim Groundwater Cleanup Levels would not be achieved in that timeframe. At EPA's request, consultants to BFI Waste Systems of North America, LLC undertook additional investigations of bedrock groundwater, which show Site groundwater will likely meet interim groundwater cleanup levels in 40 to 60 years.
