The Douglas Road/Uniroyal, Inc. Landfill site is located in St. Joseph County just north of Mishawka, Indiana. The site is approximately 16 acres in size and is located near the northwest corner of Douglas and Grape Roads. The site is bounded by the right-of-way for the Indiana State Toll Road to the north, a shopping center and an apartment complex to the east, residential properties and Douglas Road to the south, and agricultural land to the west.

In the early 1950s, the property was excavated and gravel from the site was used for the construction of the interstate. Uniroyal Plastics, Inc. leased the gravel pit and used it as a repository for plant wastes between 1954 and 1979. In December 1979, the site was closed to avoid having to comply with impending regulations pertaining to the operation of the landfill.

About 302,400 gallons of hazardous waste were disposed of at the landfill. Liquid wastes included methyl ethyl ketone, acetone, tetrahydrofuran, toluene, hexane, and xylene. Historical aerial photographs of the landfill indicate several pits containing liquid that may have been used for disposal; the largest and longest used was in the central area of the landfill.
 
Remedy:  The major components of the selected remedy include: groundwater extraction using extraction wells or collection drains to contain groundwater in the downgradient direction of the groundwater plume; groundwater treatment through construction of an artificial wetland; re-infiltration of a portion of the extracted groundwater that has undergone treatment in the constructed wetland; discharge to Juday Creek of a portion of the treated groundwater; groundwater and source area monitoring to ensure that the goals of this action are met and that downgradient water supplies are not adversely impacted by groundwater contamination; and long-term operation and maintenance of the remedy to ensure protection of public health and the environment.
