Well Water Quality in the Sylvan Lake Watershed

The Alberta Health well water database is now accessible online. It contains records for 71,698 Alberta wells that were submitted for analysis since 2002 by private well owners. Click on this link to reach the homepage of the website. A tutorial is presented to coach viewers on its use.

Following are some screen capture views of the information retrieved with a “Sylvan Lake” search for 300 wells . The left panel displays the statistical distribution of the chemical analyses and the right side map indicates where well clusters are located. Individual wells are color-coded to quickly show the composition of each water quality property. The website explains why clusters of wells are centered in the nearest surveyed section of land.

The following graphics are screen-captured displays that show the statistical distribution of well water properties or ion compositions for this set of 300 wells. The local bar graphs are overlaid on the data for all of Alberta. In general, local groundwater composition is at the low end of the provincial range.

The bottom graphic is an example of the detailed data table that may be viewed by a cursor flyover of any well dot on the online website map.

When the database is active, clicking on any well dot will display the complete set of  water chemistry data:

To compare groundwater data with the composition of Sylvan Lake itself, please consult this source of time series data archived by Alberta Environment and Parks based on data of the Alberta Lake Management Society collected during our lake sampling campaigns. As an overview, watershed groundwater contains higher concentrations of the measured constituents than does the lake water.
