Boil water advisory rescinded!

Good Water Returns !

Written by Glen Morrison Friday, 107.5 KISSFM 16 September 2011 01:52

It's finally lifted ! Just before eight last evening RDNO and Interior Health rescinded the boil water notice on the Kal Lake water system.  The notice, in effect since September second, covered 25 thousand addresses in Vernon and Coldstream.  Utilities manager Al Cotsworth says all test results and disinfection levels are satisfactory and the water quality rating is back to "good"

---------------------

What does a Good rating mean?
A good rating means the water is safe to drink with the exception for customers with immune compromised systems. Persons, who are unsure whether their immune system is compromised, should discuss the need to take precautions with their physician.  Who should take precautions? Customers with immune compromised systems are advised to seek additional protection by boiling their drinking water or using a safe alternative.

Boil Notice Continues, Source Still Uncertain, Illness

Written by Peter McIntyre Wednesday, 14 September 2011 12:20 

 

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.

RDNO 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 greatervernonwater.ca

Boil water advisory - comments.

While I do not mean to minimize the seriousness of the situation I do have some questions regarding the press release.

The bacteria counts were within the distribution system and the disinfection process has been good therefore it is unlikely that bacteria counts are due to natural processes in Kalamalka Lake. The problem might be due to bacterial colonies growing within the distribution system. One saving grace is that the bacteria in question are not the E. coli species.

Caution should be taken due to the fact that the bacteria in question are probably from internal sources within the pipes. However, we must be remembered that many people are swimming in Kalamalka Lake with no apparent health effects. One would assume that not all swimmers keep water from entering their mouth during the process of swimming.
