Code   Description / Observation / Corrective Action
313   Inadequate treatment
Observation: The distribution system is at risk. Water pressures can now be maintained due to installation of new generator that operate on primary supply well/s. Older infrastructure and water loss still indicate potential breaks or structural integrity issues within distribution lines and present a continued risk. A percentage of the water lines are at or below the water table for at least a portion of the year. These items, combined with a lack of residual disinfection, create increased risk for intrusion of pathogens into the distribution system.
Corrective Action: A variety of options are available to address identified concerns to decrease the potential for pathogen impact on the water distribution system. The District of Stewart has actively been working towards ways to reduce risk (ie. generator installation for pressure maintenance, working towards a structured annual flushing/disinfection protocol, etc). A combination of items such as the institution of an annual flushing/disinfection protocol, identifying areas of water loss, distribution system enhancements, institution of a cross-connection control program and/or incorporation of residual disinfection into the system will provide added security and safety for this system. It is strongly recommended that residual disinfection be incorporated to add an additional barrier to potential pathogen impact on the distributed water; especially during unexpected situations. Step one would be to ensure that a system is set up so that residual disinfection can be turned on (within a short time frame) if determined to be necessary. This could be used then during repairs, unknown contamination events and during the annual flushing/disinfection protocol.
320   Other (specify below)
Observation: Emergency Response Plan requires updating. Updating is in process.
