List any Inorganic or Organic parameter(s) that exceeded half the standard prescribed in Schedule 2 of Ontario Drinking Water Quality Standards. Parameter Result Unit of Date of Sample Trihalomethane ug/l Running quarterly average for 2017 The Ontario Clean Water Agency aims to strictly adhere to operational and compliance limits, however certain operational circumstances may cause results to be temporarily outside of the limits. Limits that are momentarily surpassed as a result of pump startups, power outages/generator tests, pump rotation, calibrations, alarm verification, etc. are a normal part of operations and do not indicate a true exceedance. A true exceedance will be noted and documented within the report. Page 7 of 7
