3 Describe your Drinking-Water System PUC Services Inc. operates, maintains and manages the Sault Ste. Marie water supply on behalf of the City s Public Utilities Commission. The PUC Services Inc. business office is located at 765 Queen Street East. Regular business hours are 08:30 to 16:30, Monday to Friday. The telephone number is (705) The PUC Water Treatment Operations Control Centre is located at the A.S. Boniferro Water Filtration Plant, 2059 Second Line West. The licensed operators at this facility monitor and control all aspects of water production and quality, through the use of a modern computer based control system. Water for Sault Ste. Marie is obtained from two principle sources: surface water from Lake Superior and ground water from six deep wells. Raw water from the intake at Gros Cap is pumped to the water treatment plant where a process of filtration and chlorination prepares the water for consumption. Water from the deep wells is chlorinated prior to being pumped to the distribution system. On a typical day our customers consume about 35,000 cubic metres of water. Three water storage reservoirs located in the distribution system hold up to cubic metres of water [or 1-1/2 days-average consumption].

17 Requirements of the Summary Report DWQMS Form The owner of a drinking water system shall ensure that, not later than March 31 of each year, a report is prepared in accordance with Schedule 22 of O.Reg 170/03 for the preceding calendar year. This report covers the time from Jan 1, 2011 to Dec 31, The report must: a. list the requirements of the Act, the regulations, the system s approval, drinking water works permit, municipal drinking water licence, and any orders applicable to the system that were not met at any time during the period covered by the report b. for each requirement referred to in clause (a) that was not met, specify the duration of the failure and the measures that were taken to correct the failure. The report must also include the following information for the purpose of enabling the owner of the system to assess the capability of the system to meet existing and planned uses of the system: Regulations 1. A summary of the quantities and flow rates of the water supplied during the period covered by the report, including monthly average and maximum daily flows. 2. A comparison of the summary referred to in paragraph 1 to the rated capacity and flow rates approved in the system s approval, drinking water works permit or municipal drinking water licence, or if the system is receiving all of its water from another system under an agreement; to the flow rates specified in the written agreement.

Further details pertaining to these items can be found in the body of the inspection report. 1. All trihalomethanes water quality monitoring requirements prescribed by legislation were not conducted within the required frequency. The required number of samples for THM analysis were collected from the four treatment systems in However, the samples for the first and second quarters for the Steelton well and for the water treatment plant were collected less than 60 days apart (March 4th and April 12th). Action Required: The operating authority shall review and adjust their sampling schedule to ensure that samples collected on a quarterly schedule are done so in accordance with schedule 6 of the drinking water regulations.
