From a colleague with EPCOR Water in Edmonton:<br><br>
Health Canada publishes guidelines for radionuclides and EPCOR must
ensure they are met. As far as I know we don’t do radionuclide tests in
house; the samples are sent to external labs (probably to the SRC). The
official statement in last year’s report is:<br>
<br>
EPCOR performs monitoring and testing well above the minimum required by
the regulatory approval. For example, Health Canada recommends 155
samples be collected from the distribution system each month for
bacteriological testing for a city the size of Edmonton. However, on
average, 234 samples were collected monthly. In 2011, the EPCOR Water
Laboratory carried out more than 113,000 tests on 100 parameters (47
inorganic/physical, 47 organic and 5 microbiological) for Edmonton water.
<b>Another 5,000 tests were done on 222 additional parameters (211 trace
organics and eight radionuclides) by external commercial
laboratories.<br>

Most concerns I’ve read about are related to radon in ground water
sources. I’m not aware of any such issues in the Edmonton area.<br>
