Abstract
Recent remedial actions taken by Uniroyal Chemical Ltd at their Elmira, Ontario, plant have been considered. The company has been manufacturing a wide range of organic chemicals at this plant for use in agriculture and in the plastics and rubber industries since 1942. Historically, wastes were disposed of on-site, which while common practice at the time, caused soil and water contamination by N-nitrosodimethylamine (NDMA), volatile organic compounds such as benzene, toluene, and chlorobenzene, aniline, mercaptobenzothiazole and basic compounds such as ammonia. The local hydrogeology is fairly complex and consists of several aquifers and aquitards of which the Upper Aquifer (UA) and the Municipal Aquifer (MA) have been the primary concern. They have supplied all or part of the drinking water for the Kitchener-Waterloo area and the town of Elmira. After an extensive feasibility study, the decision was made to install shallow extension wells, and a system to treat the groundwater to acceptable criteria to discharge the treated water to the river system. Development of the system, which besides ten extraction wells includes a tertiary treatment process for UV oxidation, was described. The system has been in operation since January 1997. It affords 95 to 98 per cent of containment efficiency,

Effluent requirements have been consistently met for all 18 primary contaminants, and no groundwater is being discharged into the river system.}
