Albertslund

The Naverland 26 site in Albertslund, Denmark was operated as a large-scale dry cleaner from 1965 to 1983. During this period, an estimated 5,000 tons of perchloroethene (PCE), 1,500 tons of trichloroethene (TCE), and 200 tons of 1,1,1-trichloroethane (TCA) were handled. PCE was delivered in tankers and transferred to an underground storage tank, while TCE and TCA were delivered and stored in drums. Previous studies at and around the site revealed extensive groundwater contamination from spilled or leaked chlorinated solvents, which likely resulted in the lateral and vertical migration of solvent dense nonaqueous phase liquid (DNAPL) through the clay till and into the limestone underlying the site.
