RMOW Community Water System - Inspection Report

Inspection Information:

This facility was given a low hazard rating.
More information on hazard ratings.

Violations:
A summary of the violations found during the inspection are listed below.

Code	Description / Observation / Corrective Action
304	Inadequate Water Quality / Disinfection / Treatment / Quantity Observation: 25 Inadequate treatment for the removal of parasitic cysts of Giardia / Cryptosporidium Corrective Action: I understand an RFP process has been undertaken for the design of a UV disinfection treatment plant - primarliy intended to ensure inactivation of protozoan organizims originating from the 21 Mile Creek source. Please advise of your anticipated timeframe to complete this project and note that a Construction Permit is required from our office prior to commencement of any work.
304	Inadequate Water Quality / Disinfection / Treatment / Quantity Observation: 40 Inadequate treatment to reduce turbidity from silt and organics Corrective Action: As I recall, trubidity control for the 21 Mile Creek source was originally designed to bypass surface water extraction when turbidity levels exceeded 1 NTU. More recently with the demand for additonal water flows, the turbidity bypass set point has been adjusted to 2 NTU. The GCDWQ essentially requires source water to meet the 1 NTU requirement to avoid filtration. Accordingly we require a report outlining the RMOW compliance with this guideline.

Actions Taken:
Issue Permit
The RMOW Permit to Operate this water system has been revised and now holds the following conditions:
Confirm long term plans for enhanced surface water treatment.
Provide a Cross-Connection Control Program.
Provide a Uni-Directional Flushing Program.
Maintain a Drinking Water Quality Sampling Program as prescribed.
Review the Well Protection Plan for each well source.
Review the Emergency Response Plan and update annually.
Report annually the monitoring results as prescribed.

Of these conditions the requirement for long term plans for enhanced surface water treatment, and provision of a Uni-Directional Flushing Program are new and as we have discussed previously. Furthermore I have deleted some of the outdated conditions, some of which were redundant with current minimum regulatory requirements. Please feel free to discuss these changes with me should you have any concerns.

Comments:
I recognize and appreciate the RMOW effort to develop and support a cross connection control program. In addition we should schedule a meeting to review: Revisions and updates to your Emergency Response Plan. A copy of VCH staff emergency contacts has been provided to assist you in this regard. Review your annual report. As we previously discussed, in addition to reporting all monitoring criteria we wish to see a breakdown on the volume of surface water supplied Vs. that of groundwater. See above noted comments related to turbidity also. The March 2004 groundwater assessment report from Piteau Assoc. Eng. Ltd should be reconsidered and updated where additional information has been developed to improve the accuracy of well capture zones for each well, and to consider aquifer vulnerability at the same time.
