The state Department of Environmental Conservation will resume clean up efforts Monday at the former Rickett’s Dry Cleaners, a superfund site at 2017-2019 Doubleday Ave. after tests showed more remediation of the site was necessary. The Daily Gazette reports a study of soil, groundwater and soil vapor previously performed for the state by Precision Environmental Services of Ballston Spa indicated that the primary concern on the site is chlorinated volatile organic compounds associated with prior on-site dry-cleaning operations.
