Comments:
The bacteriological sample range report for 2016 indicates satisfactory water quality was maintained within the distribution system throughout the year. Of the 429 samples submitted for analysis, one (0.23%) were positive for total coliform bacteria. We are uncertain of the reason for the one positive result, but are inclined to attribute it to sampling error in view of the FAC residual maintained in the RMOW Community distribution system. These findings are very consistent as in previous years. The water chemistry characteristics within the RMOW Community system are complex in view of the number of sources, and various extraction rates of surface water Vs groundwater. Depending on the RMOW long term water supply strategy, please consider strategies to reduce manganese levels. As we discussed, we also note the water supply tends to be undersaturated with respect to alkalinity and hardness to varying degrees according to the individual sources. VCH generally supports supplementation (ie with calcium carbonate or equivalent) however we are uncertain of the cost effectiveness in this approach in view of the extensive number of sources distributed throughout the RMOW (with each source having a unique chemistry profile). Please provide an update on your progress with implementing a cross connection control program. As we also discussed, by-law authority is considered essential to assure all backflow protection assemblies are tested annually, and we can see no method by which it can be assured otherwise. Thank you for your updated Emergency Response and Contingency Plan, and the dedicated effort in producing a comprehensive annual report. An up to date staff contact list for VCH has been provided and in return, kindly provide an updated staff contact list for RMOW for our files.
