Abstract: 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.

Data quality info:

Data quality: Scope: Scope: Hierarchy level: Scope code: dataset Lineage: Lineage: Statement: This information was originally published within the Agricultural Land Resource Atlas of Alberta. Process step: Process step: Description: The first step, in generating the Index incorporated the AVI prepared by PFRI and AAFRD, was creating Groundwater Vulnerability maps for the Hog Environmental Management Strategy (HEMS) Initiative. The methodology was further developed in Agriculture and Agri-Food Canada Technical Bulletin 2001-1E. The final data for AVI comes from Alberta Environment’s Groundwater Information Center database that contains general groundwater information from water-well descriptions called well logs. This data was standardized and interpreted for mapping purposes. The second step involved incorporating precipitation minus potential evapo-transpiration (P-PE) values taken from the National Ecological Framework for Canada ecodistrict climate files into the final index. Aquifers in areas with a higher (P-PE) value are considered to be more susceptible to contaminants through leaching to the groundwater recharge through precipitation to the vulnerability of aquifers. Integration the groundwater vulnerability and precipitation data together resulted in the final AVI ratings. Date and time: 2002-01-01T00:00:00 Source: Source: Description: The data used for the AVI comes from Alberta Environment's Groundwater Information Center database that contains general groundwater information from water-well descriptions called well logs. This data was standardized and interpreted for mapping purposes. The Alberta Water Well Information Database site contains a database of approximately 500,000 records with nearly 5,000 new drilling reports added annually. The database contains information about individual water well drilling reports, chemical analysis reports up to the end of 1986, springs, flowing shot holes, test holes, and pump tests conducted on the wells.
