Listed in Alaska Department of Commerce business license database as Neighborette Laundry (1953), White Swan Laundry (1968-1983), Quality Cleaners & Laundry (1973-1982), B & C Commercial Dry B & C Commercial Dry Cleaners & Laundry (1987), B & C Swan (1988), Fairbanks Cleaners and Linen Supply (2003-2007), M C Commercial Laundry & Dry Cleaners (1996-2004),
Currently dba ES Laundry (2011 to present).
Historical releases of tetrachloroethene (PCE) to the vadose zone likely as onsite spills (outside loading area of Laundromat, and likely inside) and from solvent disposal to wood stave underground sewer lines. Groundwater contacts the source zone and has created area of groundwater contamination that exceeds the ADEC groundwater cleanup levels, extending approximately 500 feet down gradient to the Chena River. Remediation Status: In active remediation |
