The site is located on biologically productive tidelands between Harbor Point and the Alaska Marine Highway ferry terminal near the end of Halibut Point Road . The area is used for recreational shellfish subsistence gathering.
Public Health and Environmental Concerns
Boatyard maintenance activities and trap and skeet club shooting may have contributed to heavy metals contamination. Elevated levels of metals were documented by the Alaska Department of Transportation and Public Facilities in the spring of 2002 during a study to gather preliminary data at a location proposed for dredging and construction of a new ferry terminal. Limited clam sampling was also conducted in front of the trap and skeet club. Arsenic and lead were found. DEC conducted follow-up clam sampling in August 2002 but did not find significant contaminant levels.
DEC contracted with SLR Alaska to complete a data review and risk screening in 2003. Shellfish harvest warning signs were posted late summer 2004.The Sitka Sportman’s Association recently voted to discontinue the use of lead shot. Allen Marine is taking steps to investigate potential contamination in the vicinity of its former boat maintenance facility. Institutional controls have been established on this site. Records of the site cleanup and institutional controls are available in the database. See link at top.
