Copies of these records can be obtained by calling or can be viewed at www. In some areas of Alberta, regional groundwater assessment studies are also available and may identify aquifer potential and groundwater quality.
Also check with neighbours about their experiences with well performance, well maintenance and water quality changes. Other things to consider when choosing a licensed water well contractor are: Can you talk comfortably with them about the local geology, their proposed well design and construction and the pumping equipment they recommend?
