Report Date: 5/09/7 GENERAL COMMENTS REVISED REPORT (Version 2): Canadian Drinking Water guideliens added for ease of report interpretation. DN3 MAC,AO,OG: The guidelines that have been included in this report have been taken from the Canadian Drinking Water Quality Summary Table, October 4. Criteria A = Maximum Acceptable Concentration (MAC) / Criteria B = Aesthetic Objectives (AO) / Criteria C = Operational Guidance Values (OG) It is recommended to consult these guidelines when interpreting your data since there are non-numerical guidelines that are not included on this report. Turbidity Guidelines:. Chemically assisted filtration: less than or equal to 0.3 NTU in 95% of the measurements or 95% of the time each month. Shall not exceed.0 NTU at any time. 2. Slow sand / diatomaceous earth filtration: less than or equal to.0 NTU in 95% of the measurements or 95% of the time each month. Shall not exceed 3.0 NTU at any time. 3. Membrane filtration: less than or equal to 0. NTU in 99% of the measurements made or at least 99% of the time each calendar month. Shall not exceed 0.3 NTU at any time. Results relate only to the items tested. Page 5 of 8 Maxxam Analytics International Corporation o/a Maxxam Analytics Burnaby: 4606 Canada Way V5G K5 Telephone(604) 734-7276 Fax(604) 73-2386

Used to evaluate method accuracy. Method Blank: A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination. (Matrix Spike): The recovery in the matrix spike was not calculated. The relative difference between the concentration in the parent sample and the spiked amount was too small to permit a reliable recovery calculation (matrix spike concentration was less than 2x that of the native sample concentration).
