 What should I test for?



The Safe Drinking Water Act, 2002 (SDWA) requires that testing of drinking water be performed by approved and licenced laboratories. All Well Wise drinking water tests are carried out by Paracel Laboratories Ltd., a laboratory approved under this Act by the Ontario Ministry of the Environment.

Well Wise water testing is carried out by Paracel Laboratories Ltd., a member of OGWA.
