Wrongfully accused: City's water quality
2000
Overview
Why is the Ministry of the Environment pushing us to filter our water at a cost of $20 million? Good question. It turns out that there are certain protozoans (giardia and cryptosporidium mainly) that can cause illness and potentially death in immuno-compromised individuals if enough of their cysts were to be ingested. Chlorine does not kill these cysts (more correctly called oocysts). So the important question becomes: \"Are these parasitic protozoans in Trout Lake and if so are they present in sufficient concentration to cause concern?\" That is what all the fuss is about. Gord Miller, while he was a private environmental consultant prior to becoming the environmental commissioner, analysed the risk of finding these parasitic cysts in Trout Lake and came to the conclusion that the probability of finding these parasites in Trout Lake is very very low, but not zero. To their credit, both the MOE and our Medical Officer of Health want the risk as near zero as possible. The MOE is pushing for a $20-million filtration plant, but it also appears that due to the exceptional water quality of Trout Lake's raw water, ultraviolet radiation would also kill these cysts (were they present), at a cost of about $1 million. And so enters fiscal responsibility into the discussion. At the moment MOE has a policy not a regulation to coerce municipalities to filter their water . . . and no money to help out.
