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. There is approximately 500,000 records within the database with about 5,000 new records being added each year.

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.

Alberta Innovates Technology Futures was contracted by Alberta Environment to review and evaluate the data held in the Baseline Water Well Testing database to determine trends in baseline conditions and any observable changes in water quality of wells that were tested more than once. Includes several recommendations for future data capture and entry.

This data release contains water chemistry data used to create a total dissolved solids (TDS) map of the Wapiti / Belly River hydrostratigraphic unit (HSU) as part of the Alberta Geological Survey’s (AGS) Provincial Groundwater Inventory Program. It also contains the calculated difference (residual) between the modelled distribution of TDS and measured values from wells. The source datasets are water well chemistry data from Alberta Environment and Parks' Alberta Water Well Information Database (AWWID) and formation water chemistry data from oil and gas well drillstem tests (DSTs) and production fluids. Data have been processed, relevant records selected, and outliers removed to compile this dataset.Last Update: 2019-Feb-05Uploaded by: Rasto Elgr

This data release contains pressure data used to create a hydraulic head map of the Wapiti / Belly River hydrostratigraphic unit (HSU) as part of the Alberta Geological Survey’s (AGS) Provincial Groundwater Inventory Program. It also contains the calculated difference (residual) between the modelled distribution of hydraulic head and measured values from wells. The source datasets are head data from Alberta Environment and Parks' Alberta Water Well Information Database (AWWID) and pressure data from drillstem tests (DSTs) from oil and gas wells. Data have been processed, relevant records selected, and outliers removed to compile this dataset.Last Update: 2019-Feb-05 Uploaded by: Rasto Elgr
