The Aquifer Vulnerability Index (AVI) is a method of assessing the vulnerability of aquifers to surface contaminants in Alberta. An aquifer is a geological formation that is permeable enough to transmit sufficient quantities of water to possible to support the development of water wells. In the assessment of aquifer vulnerability to potential contamination, the depth to the aquifer and the types of geological materials above them are considered. For example, aquifers closer to the surface overlain with pervious surface materials are more vulnerable to contaminants, as compared to aquifers found deeper and covered with a thick layer of impervious material. The AVI ratings indicate the potential of surficial materials to transmit water withy contaminants to the aquifer over a period of time. This data was created in 2002 using ArcGIS.

These data polygons are sites which were visited by Dr. Jozsef Toth during his 1964 to 1969 fieldwork. Dr. Toth is a distinguished hydrogeologist who developed and published his landmark 'Unit Basin' theory of steady state flow leading to the fundamental concept in hydrogeology known as 'Tothian flow system theory'. His contributions to hydrogeology turned the Research Council of Alberta, and subsequently the University of Alberta, into internationally renowned institutions for hydrogeological research. The sites in this data set show the locations of wetlands referenced in Alberta Geological Survey report INF 143 and they are numbered accordingly. The data are in ESRI shapefile format.

This dataset contains an extract of water chemistry data from the Cold Lake - Beaver River Basin project area. The work was completed in 2004 under contract to Alberta Environment (AENV). Information was obtained from industry and government sources. These data are available in three text files, each representing one table in the original database. See the accompanying jpg of the original relationship diagram to understand how the data in the text files tables are related.

Alberta Geological Survey partnered with Alberta Environment (AENV) Northern Region to compile and analyze groundwater data in the Cold Lake-Beaver River Drainage Basin. This compilation and analysis assisted AENV and its stakeholders to complete an update of the Beaver River-Cold Lake Water Management Plan. This digital file provides the contours of the hydraulic-head distributions for the Grand Centre, Sand River, Ethel Lake and the Muriel Lake formations, and the Empress Formation Units 1 and 3 based on reported static-water levels from water wells within the study area.

These data points are sites visited by Dr. Jozsef Toth during his 1964 to 1969 fieldwork. Dr. Toth is a distinguished hydrogeologist who developed and published his landmark 'Unit Basin' theory of steady state flow leading to the fundamental concept in hydrogeology known as 'Tothian flow system theory'. His contributions to hydrogeology turned the Research Council of Alberta, and subsequently the University of Alberta, into internationally renowned institutions for hydrogeological research. All datapoints relate to the sites in Alberta Geological Survey report INF 143. Field parameters (Temperature, Electrical Conductivity, and Flow Volumes) measured or estimated were retained as attributes to the point data. The data are in ESRI shapefile format.

These data vectors are digitized from field maps created by Dr. Jozsef Toth during his 1964 to 1969 fieldwork. Dr. Toth is a distinguished hydrogeologist who developed and published his landmark 'Unit Basin' theory of steady state flow leading to the fundamental concept in hydrogeology known as 'Tothian flow system theory'. His contributions to hydrogeology turned the Research Council of Alberta, and subsequently the University of Alberta, into internationally renowned institutions for hydrogeological research. Within this shapefile there are three regional lines which run parallel to dip in the Alberta basin. These lines are the boundaries used by Dr. Toth to restrict his groundwater field investigations. There are also vectors which he has highlighted as areas of recharge and discharge that relate to some of the sites in Alberta Geological Survey report INF 143 report, but are not directly referenced. There are a few vectors in the Wainwright mapsheet which were not labeled or referenced in the report so they were omitted. The data are in ESRI shapefile format.

This dataset accompanies Open File Report 2009-02. Between 1971 and 1983, the Alberta Research Council created a series of hydrogeological maps of Alberta. The geologists examined the sediment types present and used existing water well information to assign yield values to distinct zones within the mapped areas. They also looked at the materials, generally to a depth of 305 metres (1000 feet) below ground surface, and added the yields of the sediments encountered within this interval to arrive at a yield value for the whole. Alberta Geological Survey compiled the shapefiles for the yield polygons, digitized by the Prairie Farm Rehabilitation Agency, and then digitized the remaining linework for the remaining map areas. Afterwards, we created a geodatabase of the yield polygons for the entire province and assigned yield values to the polygons based on the original maps. We also assigned the most likely formation name, age and lithology to the yield polygon.

In 2002 the Alberta Geological Survey initiated a project to scan and digitize water well geophysical logs from Alberta Environment and Sustainable Resource Development (ESRD) water well data holdings. Casual and summer student staff scanned hard copy logs systematically by NTS mapsheet starting with the Cold Lake area. Scanned logs were digitized into Log ASCII Standard version 2 by Divestco Ltd. This data release consists of 8,763 LAS files, comprised mostly of resistivity logs, and a tab delimited index file. About 1% of the LAS files also contain a natural gamma log. The API number (APIN) in the log header refers to Alberta Environment's water well identifier number used at the time the logs were digitized. There are 205 records where the API number starts with 900. We were unable to confidently match the log file surface location to an AENV location for these records. The approximate aerial coverage is from latitude 49 degrees to 56 degrees N and from longitude 110 degrees to 120 degrees W. This work concluded in March, 2007.

These Alberta spring locations were digitized from the 1:50 000 Alberta Hydrogeology Information Map Series (48 atlases) by the Alberta Research Council from the 1960s and 1970s. Springs were digitized as part of the digital data capture process.
