This assessment characterized natural and man-induced hazards to drinking water quality as physical, chemical or biological. Existing research was augmented by field studies of water currents near the intake and lab studies on the fall rates of particulate
contaminants. This research was used to define a proposed Intake Protection Zone (IPZ), based on a two hour travel time of water currents to the intake. The hazard assessments were then divided into those occurring inside the IPZ and those occurring
outside the IPZ. The same hazard occurring outside the IPZ was given a lower risk rating than that hazard presented within the IPZ where there is less dilution and less time to react to a contaminant.
Specific recommendations and action plans were developed: (1) source protection for South Kalamalka Lake (2) water treatment and system protection plan and (3) future large expenditure improvements to the DLC Kalamalka Lake water system. Key recommendations include: applying for a License of Occupation over the Intake Protection Zone; considering bylaws to protect the foreshore; modifying the water quality monitoring to comply with IHA filtration deferral; replacing the raw water sample line on the intake to comply with IHA requirements; continue to collect data on extending the intake; have a Comprehensive Emergency Plan prepared, and work with the railway and Hwy 97 on materials hauled and appropriate spill containment.
