The Glacier Bay Source Control Area is located along the western side of the LDW Superfund Site between 1.2 and 1.6 miles from the southern end of Harbor Island. The map shows the main properties of interest in this area which include: Alaska Marine Lines, Duwamish Shipyard, Inc. (Duwamish Shipyard), Glacier Northwest, Inc. (Glacier Northwest), and the former MRI Corporation, which leased the northern portion of Terminal 115.
The upland areas adjacent to the LDW have been industrialized for many decades. Historical and current commercial and industrial operations in the vicinity of Glacier Bay include cargo handling and storage, vessel repair and maintenance, concrete manufacturing, lumber milling, charcoal production, manufacture of glues and resins, and tin reclamation.
The following chemicals are considered to be contaminants of concern at Glacier Bay with regard to potential sediment recontamination
| Metals | Organics |
| Arsenic | Dioxins/furans |
| Mercury | PCBs |
| Zinc | Phthalates (BEHP, butyl benzl phthalate) |
| Copper | PAHs |
| Lead | 1,2-Dichlorobenzene |
| Antimony | Pentachlorophenol |
| Tin | Benzyl alcohol |
| Organo-tin compounds |
Ecology is the lead for source control for the LDW Superfund site. Source control is the process of finding and then stopping or reducing as much as possible releases of pollution to the river. Ecology looks at the drainage for Glacier Bay in order to determine what work needs to be done for Source Control. The Glacier Bay drainage basin outlines the area where sources need to be controlled (see map). The routes for contaminants to Glacier Bay sediments include: direct discharges via piped outfalls, bank erosion from adjacent properties, surface runoff from adjacent properties, groundwater discharge, air deposition, and spills directly to the inlet.
Ecology is in the process of developing a Source Control Action Plan for Glacier Bay which will describe what source control actions are necessary. As part of the Source Control Action Plan, Ecology hired a contractor to put together a Summary of Existing Information and Data Gaps report. You can view this report here:
