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: 30 Inadequate treatment for the removal of metals (i.e. Iron, Manganese, etc.) Corrective Action: 2) As part of your groundwater development program, treatment will need to be provided for the removal of metals where encountered. In this regard well W212 (Function well) will require treatment for the removal of iron to comply with the AO of the GCDWQ.
304	Inadequate Water Quality / Disinfection / Treatment / Quantity Observation: 25 Inadequate treatment for the removal of parasitic cysts of Giardia / Cryptosporidium Corrective Action: 1) As we discussed, the existing chlorine based disinfection process is not considered to be effective for the removal of Giardia or Cryptosporidium. I note the RMOW is undertaking a groundwater resource study with a view of conversion to exclusive use of groundwater supplies, and agree this is logically the first consideration. In the event you must still maintain reliance on surface water sources, the best long term approach would be to move towards filtration (ie membrane filtration) of surface supplies for the removal of turbidity, cysts, etc. In the interim, consideration should be given to installing a secondary treatment barrier (ie UV treatment), provided the surface sources can be by-passed to avoid turbidity peaks. The extensive recreational access within the surface water catchment areas underscores the importance of this additional measure to prevent the transmission of waterborne disease.
305	Inadequate Analysis Data / Monitoring of Water Quality Observation: 10 Inadequate chemical sampling data (i.e. parameters; frequency; etc.) Corrective Action: Please ensure THM monitoring is conducted at representative points within the distribution system. Initial sampling frequency should be quarterly, subject to review based on results.
309	Inadequate Emergency Response Plan / Implementation Observation: 10 Emergency Response Plan has not been updated to include additional hazards / revised contact lists / etc. Corrective Action: Please ensure an updated copy of your emergency response plan is provided in an electonic format with current staff names and contact numbers. As we discussed, this plan should also be expanded to address the RMOW procedures to monitor and report risks associated with tampering of reservoirs, vandalism, etc. This plan should be reviewed and updated annually.

Comments:
This is a good example of a well managed waterworks system. Bacteriological water quality for the year 2001 to present is excellent. I appreciate the RMOW commitment to operator training and support for the BCWWA conferences. The RMOW has also been proactive in providing continuous on-line monitoring for turbidity at each surface source; as well as continuous on-line monitoring of the water disinfection process - at both the source and within the distribution system. As we disucssed, a Well Protection Plan should be developed for each well source and a Cross-Connection Control Program should be developed to protect the distribution system integrity. I anticipate these items will be incorporated as operating conditions of your Permit in future. I appreciate the efforts of your staff in maintaining a close working relationship and open communication over many years - thank you.
