Problems/Comments
This site was the location of the old Ketchikan General Hospital building. After the site was a hospital, the building was converted to the Bawden Street Apartments which served the community as the primary rental housing for the Ward Cove Pulp Mill workforce until the mill was permanently closed in March 1997. The building was temporarily used to house Summer tour guides but it has been vacant for the past 9 years. The City of Ketchikan has documented the immediate danger of asbestos in and around the building. In 2012-2013, the building was demolished by the City as public nuisance. Samples of soils at the site have verified lead present at 692 mg/kg, in excess of 400 mg/kg cleanup level.
