PffiS 3119 EXECUTIVE SUMMARY DRINKING WATER SURVEILLANCE PROGRAM FORT FRANCES WATER TREATMENT PLANT 1991 AND 1992 REPORT The Drinking Water Surveillance Program (DWSP) for Ontario is a monitoring program providing immediate, reliable, current information on drinking water quality. The DWSP officially began in April 1986 and is designed to include all municipal supplies in Ontario. In 1991, 96 supplies and in 1992, 109 supplies were being monitored. The Fort Frances water treatment plant is a conventional treatment plant which treats water from the Rainy River. The process consists of coagulation, flocculation, clarification (upflow clarifier) filtration, pH adjustment, fluoridation and disinfection. This, plant has a design capacity of 16.9 x 1000 m^/day. The Fort Frances water treatment plant serves a population of approximately 9,000. Water at the plant and at three locations in the distribution system was sampled for the presence of approximately 180 parameters. Parameters were divided into the following groups: bacteriological, inorganic and physical (laboratory chemistry, field chemistry and metals) organic (chloroaromatics, , chlorophenols, pesticides and PCB, phenolics, polyaromatic hydrocarbons and volatiles) and radiological (radionuclides) Most . laboratory analyses were conducted at the Ministry of the Environment and Energy facilities in Rexdale, Ontario. Radionuclides were analyzed by the Ministry of Labour. Table A is a summary of all results by group. In 1992, the Ontario Drinking Water Objective for fluoride was rfeovurisetdretaote1d. 5anmdg/dListtorirbeuftleedctwoapteerratsiaomnpallesreeqxuciereedmeednt1s..5 Tmwgo/Lofwitthhe a maximum value of 2.1 mg/L. It is recommended that the fluoride addition practices be reviewed. No other known health related guidelines were exceeded. The Fort Frances water treatment plant, for the sample years 1991 and 1992, produced acceptable quality water and this was maintained in distribution system.
