Superfund Sampling Locations
Morton Beverly Site
The Morton Beverly Investigation (CH2M Hill, 1993a), was a state hazardous waste site
in Massachusetts. Tidal and subtidal areas in the Danvers River, which is a
tributary of Massachusetts Bay, had elevated levels of mercury. The sampling plan
was designed and implemented to determine the risk, extent of contamination, and area
of sediments requiring mitigation.
Sullivan's Ledge
Sullivan's Ledge (Metcalf & Eddy, 1991) was a CERCLA investigation of a freshwater
wetland contaminated with PCB. The sediments were the focus of the investigation and
samples were collected not only to evaluate the extent of risk, but also to delineate
the area requiring excavation and remediation.
Pine Street
The Pine Street investigation (Kappleman, 1993) was an evaluation of a Lake Champlain
Canal, declared a CERCLA site due to contaminated sediments and groundwater.
Sampling was done in the canal to delineate the extent of contamination and degree of
human health and ecological risk.
Bay Drum Wetland Impact
Sediments were sampled in wetlands (1) to evaluate the ecological status of wetlands
associated with the Bay Drums, Peak Oil, and Reves Southeastern hazardous waste sites
near Tampa Bay and (2) to identify the possible sourcesof toxicity (EPA, 1993c). A
total of 12 samples were collected, 10 from three wetland test sites (affected areas
or hot spots) and 1 from each of two reference stations.
Ice Creek
This study represents an impact assessment rather than a risk assessment. The study
site was a small stream in southeastern Ohio (EPA, 1993a). The stream received long-
term waste discharges from a coke production facility before closing in the 1980s.
The study included, examinations of the surface water and sediment chemistry for
organic and inorganic chemicals, as well as aquatic biota.
Commencement Bay
An ecological assessment of Commencement Bay, Washington, was performed near
shore/tidal flats areas (EPA, 1993b). Field studies were designed to document the
extent of sediment contamination and adverse biological effects, including sediment
toxicity, alternations to benthic macroinvertebrate assemblages, chemical residues in
tissues of crab and English sole, and liver lesions in English sole. The study
approach was based on three premises: (1) site-specific field data were needed to
establish cleanup goals, (2) no single biological indicator could be used to define
areas of risk, and (3) adverse biological effects were linked to sediment
contamination, and chemical-biological relationships could be characterized
empirically. The site was divided into nine study areas, depending on industry and
associated waterways. A total of 53 sample stations were established.
