2022 WwTF Annual Report - March 2023 - Part 1 - signed

The effluent phosphorous monthly average concentrations all met the 0.18 mg/L monthly average compliance limit, and the effluent annual average phosphorous concentration of 0.024 mg/L (rounded to 0.02 mg/L) surpassed the record low from the previous year and met the Lake Simcoe Phosphorus Reduction Strategy limit of 0.1 mg/L. [...] The result is that the WwTF met effluent phosphorus concentration and loading compliance limits set by the ECA and the LSPRS. [...] The analyst in consultation with the Laboratory Manager reviews raw data and the steps followed in the test procedure and take the appropriate action(s) to identify and resolve the situation. [...] If any quality control sample results fall outside the control limits, the acceptance or rejection of the results is at the discretion of the analyst in consultation with the Laboratory Manager. [...] The supervisor or senior analyst designated to the co-ordination/supervision of the respective test is responsible to ensure the continual monitoring of the method's performance.
