Health Consultation: Winona Soil and Groundwater Site (Clarks Lane/Gilmore Avenue), City of Winona, Winona County, Minnesota. EPA Facility ID: MND981091465

摘要

The Leaf Dry Cleaner site is located at 1405 Gilmore Avenue in the City of Winona, Minnesota approximately 110 miles southeast of St. Paul along the Mississippi River. The site contains soil and groundwater contaminated with tetrachloroethylene, also known as perchloroethylene (PCE), its breakdown products, and petroleum chemicals. PCE is a common dry cleaning solvent. Prior to January 2003, the Leaf property consisted of two buildings: a main building used for the dry cleaning business plus storage, and an unattached two-stall garage. Before being occupied by a dry cleaner, the property was used as an auto service station. The Leaf property is bordered on the north by Gilmore Avenue, to the east by Clarks Lane and the Gilmore Avenue carwash, to the south by a garage and a single-family residence, and to the west by a motel. The surrounding area consists of a mix of residential and commercial properties, and St. Mary's University with associated athletic fields. The site location is depicted in this dcoument. A release at the site was first identified in 1989, when Minnesota Pollution Control Agency (MPCA) staff sampled potable wells in the area of the site in response to complaints about petroleum odors in the water. Water sample analyses detected petroleum constituents in one well and chlorinated solvents in several other area wells.
