5 APPENDIX A WATER SYSTEM OPERATING CONDITIONS FOR GRAHAM LAKE IMPROVEMENT DISTRICT 3567 East Road Denman Island, BC, V)R T0 Terms and Conditions. Water must be treated in accordance with Drinking Water Treatment Objectives for Surface Water Supplies in British Columbia to achieve the following: o 4 log removal/inactivation of viruses. o 3 log removal/inactivation of Giardia cysts and Cryptosporidium oocysts. o 2 treatment processes. o NTU turbidity (maximum) in finished water. 2. Compliance with the following timelines: Tasks Completion Date a) Maintain an ongoing water quality monitoring program Ongoing acceptable to the Drinking Water Officer. This water quality monitoring program should be reviewed annually with the Drinking Water Officer and revised accordingly. b) Identify potential treatment options. October, 8 c) Select a final treatment technology. January, 9 d) Obtain a Permit to Construct or Waiver from the July, 9 Vancouver Island Health Authority (VIHA) Public Health Engineer. This permit is for the construction of all works necessary to meet the VIHA Surface Water Quality Treatment Objectives. e) Construct and Commission all works necessary to meet the October, 2 Island Health Surface Water Treatment Objectives. 3. Maintain routine monitoring to ensure the efficacy of disinfection and/or treatment technology according to industry standards. Maintain records of all monitoring conducted, deviations from standard operating procedures, and customer complaints.

6 4. Maintain maintenance and operating procedures that abide by BCWWA standards or equivalent. Maintenance and Operating Procedures shall include: o Monitoring of source, and intake. o Maintenance and monitoring of disinfection equipment, and treatment equipment. o Location/availability of spare equipment and parts. o Maintenance and monitoring of distribution lines. 5. Adhere to Sampling Program as approved by the Drinking Water Officer. The Sampling Program is to include the following: o Bacteriological Testing on a frequency established by the Drinking Water Officer. o General Chemical Testing at a minimum of every 5 years that addresses the VIHA Guidelines for Approval for Waterworks. 6.

Used to evaluate the variance in the measurement. Matrix Spike: A sample to which a known amount of the analyte of interest has been added. Used to evaluate sample matrix interference. Value Recovery Spiked Blank: A blank matrix sample to which a known amount of the analyte, usually from a second source, has been added. Used to evaluate method accuracy. Method Blank: A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination. UNITS QC Limits (Matrix Spike): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and the spike amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than the native sample concentration) (Duplicate RPD): The duplicate RPD was not calculated. The concentration in the sample and/or duplicate was too low to permit a reliable RPD calculation (absolute difference <= 2x RDL). Page 0 of 2
