Good news and bad news on pitcher filters

Oh pitcher filter. Why did you have to disappoint us, so? Yes, in this week’s Ecoholic column I talk about the short comings of Canada’s favourite water filter, Brita, as well as other pitcher filters. Seems they do reduce heavy metals like mercury and used to meet lead reduction standards, and then the standards improved and the pitchers couldn’t keep up. So yes, they do reduce lead somewhat, but not enough to meet NSF standards. On the bright side, activated carbon filters do seem to seriously reduce the presence of trace pharmaceuticals in water. More good news (not mentioned in the column), last year, Toronto voted to bring in ultra violet filtration to the city’s water, which will also slash the presence of pharmaceuticals in our water supply. A very good thing, especially in light of a new federal water study out of the U.S. that found 112 toxic materials (from flame retardants and pesticides to personal care and cleaning chemicals, as well as drugs like the diphenhydramine, Benedryl) downstream from wastewater treatment plants. For all the deets on filters, check out this week’s column. 

Oh and as for my point about carbon filters not removing fluoride and pestering your local councillor about removing fluoride from your local water supply, thought I’d share a link to a full news article I did a while back for NOW Mag on the problems with fluoridated water as well as a link to Canadians Opposed to Fluoride.

You may have spotted in Ecoholic Body I leave the choice on fluoridated toothpaste in your hands. But that’s a whole ‘nother topic for another day.

 

What more can we do to conserve water?

A certain amount of mythology is woven into every nation’s identity. Canadians, for instance, tend to believe that our fresh water sources are vast and infinite and that we ourselves are decent water conservers, thank you very much.

It’s a shame that we’re totally out to lunch on both counts.

True, the Great Lakes hold an impressive 20 per cent of the world’s fresh water, but only 1 per cent of that is renewable – not so comforting when you realize that we are the world’s second-biggest water hogs per capita (just behind our neighbours on the other side of those lakes).

How much water do you think you use in a day? Add up every flushed toilet, brushed tooth, rinsed veg, washed dish and cleaned pile of laundry and, just at home, Canadians squander a good 125,000 litres per person per year.
