Saskatchewan
Environment requires that at least once per year waterworks
owners provide notification to customers of the quality of
water produced and supplied as well as information on the
performance of the waterworks in submitting samples as required
by the Minister’s Order or Permit to operate a waterworks.
The
following is a summary of The Town of Churchbridge
water quality and sample submission compliance record for
the (2008) calendar year. This report was completed
on February 18, 2009.
Readers
should refer to Saskatchewan Environments “Municipal
Drinking Water Quality Monitoring Guidelines, November 2002,
EPB 202" for more information on minimum sample submission
requirements and the meaning of type of sample. Permit requirements
for a specific waterworks may require more sampling than outlined
in the department’s monitoring guidelines. If customers
need more information on the nature and significance of specific
water tests, for example, “what is the significance
of Selenium in a water supply”, more details are available
from:
