Site Description
[Back to Top]

The Saco Municipal Landfill covers approximately 90 acres and has been owned and operated by the City of Saco since 1960. The site consists of four distinct disposal areas. Area 1 is a closed and capped municipal dump that was used for open burning of household and industrial waste. Area 2 is an inactive industrial dump that accepted bulk and demolition debris. Area 3 is a relatively small area of about 1 acre in which wastes such as tires and leather and rubber scraps from local industries were dumped. This uncovered area is located on the outside of the service road that circles Area 4. Area 4 is a closed landfill that accepted household waste and tannery sludge containing chromium and other heavy metals, as well as volatile organic compounds (VOCs). The sludge was placed in unlined trenches, often directly in contact with groundwater. Area 2 has a leachate collection system, but there is no evidence of liners or leachate systems in other disposal areas. There are approximately 32,000 people living within a 3-mile radius of the site. Approximately 130 people live within 1 mile of the site. Water and sediment in Sandy Brook, which flows through the site, and groundwater beneath the site have shown elevated levels of iron and arsenic. Approximately 700 people obtain drinking water from wells located within 3 miles of the landfill. In 1975, the Biddeford and Saco Water Company extended water lines along Jenkins Road and Route 112. All four landfill areas are currently capped and monitored natural attenuation of groundwater contaminants is ongoing.

Threats and Contaminants
[Back to Top]

Wastes produced by local industries may be the source of contamination in the groundwater, surface water, sediments, and soil in the Saco Landfill site. Industries in the area produce leather goods, plastics, vinyl stripping, machine parts, textiles, foam products, and finishes. Typical wastes from these industries include heavy metals, chromium, solvents, dyes, polymers, and phthalates. The groundwater contains elevated levels of VOCs and heavy metals including iron, manganese, and arsenic. Sandy Brook has been shown to be contaminated with elevated levels of heavy metals; primarily iron and arsenic.

Cleanup Approach
[Back to Top]

The site is being addressed in two stages: initial actions and a long-term remedial phase focusing on cleanup of the entire site.

Response Action Status
[Back to Top]

Initial Action In 1975 the City of Saco installed a new water line in to serve adjacent residents. Between 1976 and 1985 two of the four site landfills were closed and capped under the oversight of the Maine Department of Environmental Protection (MEDEP). In 1989, the remaining two landfills stopped receiving waste and the site was placed on the NPL in 1990. In 1995 the City of Saco, entered into a Administrative Order with EPA to complete a Remedial Investigation/Feasibility Study (RI/FS) to address the remaining two landfills and address the nature and extent of contamination at the site.

Entire Site: Following the intitial actions taken at the site, data collected through the RI/FS was used to support a Non-Time-Critical Removal Action (NTCRA) to cap the remaining two landfill areas (3 and 4) to prevent direct contact exposure with landfill soils and to reduce groundwater migration of contaminants through the site. Capping began in 1996 and was completed in 1998. Following RI/FS completion, EPA signed a Record of Decision (ROD), selecting monitored natural attenuation as the long-term remedial action for the site. Groundwater and stream sediments are monitored annually to assess site conditions.

Environmental Progress
[Back to Top]

A municipal water line extension and capping of all four landfills effectively reduced exposure to site contaminants, is reducing the generation of contaminated leachate from the landfills, and is promoting the process of groundwater restoration. Long term monitoring of the groundwater and sediments continues.

Current Site Status
[Back to Top]

The most recent second five-year review report (September 2010) documents that the site continues to be protective of human health and the environment in the short term. EPA is currently working with the Maine Department of Environmental Protection (MEDEP) and City of Saco to oversee a long-term monitoring program to evaluate natural attenuation of groundwater contaminants and to evaluate current site conditions. Regular five year reviews are conducted to ensure the protection of human health and the environment. The third five-year review is currently underway and will be released to the public in the Fall of 2015.
