Enviro-Tech's GIS - Alberta resources

A wide array of products is available to assist in planning a wide variety of needs. These range from water well plots and queries within the water well database to surficial geology maps to maps showing glacial overburden over bedrock in glacial valleys. For a more setailed description of these products, please see the areas below.

Water well GIS Our GIS database contains a vast array of data on water wells in the province ranging from the depth of the well to what materials were drilled through while establishing the well.

• Queries of the database are produced and distributed in Microsoft Access 97/2000 formats to ensure simple, timely database querying. For a nominal handling fee, the database can be exported into other database formats.
• Enviro-Tech Surveys has deciphered and converted the database code into a descriptive, user-friendly format for prompt data retrieval or for spatial GIS applications.
• Each well has a unique identification number which is the primary key by which all database records are linked.
• The information in the database is current to January 1, 1999 with updates on an ongoing basis as data is made available by the government.
• There are over 324 000 water well records available in the province.
• These records are available by the township either in database format or hard copy where the cost is by record count. Customized maps can also be ordered depicting whatever the client so chooses for a nominal fee.

The unique water well identification number links all features between the data sets. If no information is available for a portion of a data set, you will only be charged for those well records in the data set that contain the information that you requested.

Water well database field descriptions

Surficial Geology Surficial geology shows what material is encountered initially on the surface and can range from glacial till to gravel deposits. Maps can be ordered showing the surficial geology of most areas of Alberta.

Drift thickness (Glacial Valleys) Drift thickness shows the extent of glacial overburden over bedrock. This can alert geophysicists to potentially bad seismic data areas. Maps indicating these areas as well as pre-glacial valleys are available for Alberta.

Flowing Shot Hole product line A flowing shot hole is a drilled (seismic) hole that has entered an underground water source that has sufficient pressure to cause the hole to "overflow". These maps typically depict near-surface aquifers and problem areas for drilling and are available for the majority of Alberta. The sample map at the right represents all the flowing holes in a county.
