Landfill 1

Remediation of Landfill 1 is Underway 

​

The Landfill 1 Area is located west of the manufacturing area. There were two discrete disposal areas used as well as a surface impoundment for wastewater. This area was closed and capped with a plastic (Hypalon) material in approximately 1980. 

Mallinckrodt US LLC worked with the Maine Department of Environmental Protection to finalize the Corrective Measures Implementation Plan that details the design of the remediation. 

​

The remediation of Landfill 1 began in 2018 and will primarily consist of excavating certain soils with mercury concentrations above the Media Protection Standards. Soil samples will be collected during the remediation process to confirm that the design criteria is being met; excavated soils will then be transported off site for disposal in secure landfills. After completion of the excavation of soils, the area will be backfilled, graded and restored with vegetation similar to the restoration work that was completed at the Landfill Ridge.

​

New England-based environmental firm Charter Environmental was chosen to conduct this phase of site remediation. Charter, which has been working on the site for more than a year, was recently selected as one of the Top 30 environmental remediation firms in the country by Engineering News Record (ENR) magazine. Their experience with high-profile Maine projects, such as the Callahan Mine Superfund Site Remedial Action in Brooksville, and the Casco Bay Pipeline Remediation in Brunswick, was an important factor in their selection for the Orrington project.
