Problems/Comments
A registered 550-gallon diesel storage tank (Tank #1) located under the driveway adjacent to Wastewater Pump Station 5 (PS5) near the Ketchikan waterfront was removed in August 2010 because the facility no longer needed to store a large quantity of fuel at that location. Sampling and soil excavation conducted in 2011 did not meet 18 AAC 78 requirements for permanent closure. During later investigations the former locations of the tank and piping were not precisely known so that sampling locations were to some extent estimated. On May 1, 2013 consultant BGES sampled soil and groundwater at the presumed former UST and UST piping locations with the maximum contaminant level in soil 110 mg/kg DRO (below the applicable cleanup level) and the groundwater analytical result 2.2 mg/L, exceeding the DRO cleanup level for groundwater of 1.5 mg/L. BGES recommends the site for no further action status.
