Boil Notice Continues, Source Still Uncertain, Illness

Officials have decided it's still not safe to lift a boil water notice on the Kalamalka Lake source.

The notice has been in effect since September 2, impacting 25,000 customers in Vernon and Coldstream.

Al CotsworthRDNO Utilities manager Al Cotsworth (pictured) says it will remain in effect at least until Friday to allow for another set of tests, as there's still some signs of bacteria in the system.

He says the source of the problem may not be the minerals produced from the lake's natural color-changing process after all.
"We're not sure about that now. We have some other information that suggests another source. Basically, when water goes through a pipeline, there's particles in the water and they settle out. I believe it might be that that is happening."

Cotsworth says small particles of algae suspended in distribution pipes may be getting knocked loose during peak flow.

He adds about ten people have reported symptoms of diarrhea or a stomach ache, but he notes that's a very small percentage of the 25-thousand customers, and it's not known for sure if it's linked to the water.

About 300 homes in the east part of East Hill and in Middleton Mountain were recently switched to the Duteau Creek source, and customers are advised to check their water source at
