Health Assessment for Seattle Municipal Landfill (Kent Highlands Landfill) Kent, King County, Washington, Region 10. CERCLIS No. WAD980639462

摘要

The Kent Highlands Landfill, also known as the Seattle Municipal Landfill, is located in Kent, Washington, approximately 14 miles south of Seattle. The landfill operated from 1968 to 1986 and accepted municipal waste from Seattle and surrounding areas. The wastes consisted of residential, industrial, and commercial materials. The site, which has been proposed for inclusion on the National Priorities List, is inoperative and closure activities are under way. Leachate and soil gases, mostly methane, are now detected at the site. The leachate is reported to contain organic contaminants and some heavy metals. The Agency for Toxic Substances and Disease Registry considers the Kent Highlands Landfill a potential public health concern because of the presence of methane gases generated on-site and the possible migration of contaminants from the site to surface water in the vicinity and possibly contaminating edible aquatic life.
