Inorganic Parameters These parameters are tested as a requirement under 170/03. Sodium and Fluoride are required to be tested every 5 years. Nitrate and Nitrite are tested quarterly and the metals are tested annually as required under 170/03. In the event any of the parameters exceed half of the maximum allowable concentration the parameter is required to be sampled quarterly.  MAC = Maximum Allowable Concentration as per O. Reg. 169/03  BDL = Below the laboratory detection level Sample Date Sample MAC Exceedances Exceedances (yyyy/mm/dd) Result MAC 1/2 MAC Treated Water Antimony: Sb (ug/L) - TW 2020 01 13

*There is no "MAC" for Sodium. The aesthetic objective for sodium in drinking water is 200 mg/L. The local Medical Officer of Health should be notified mg/L when the sodium concentration exceeds 20 mg/L so that this information may be communicated to local physicians for their use with patients on sodium-restricted diets.
