AbstractMany groundwater studies have been completed in Southern Ontario; however, there remains no regional aquifer compilation and no central repository of aquifer information. Furthermore, there is no repository of Source Protection datasets and poor linkages (indexing) between various provincial databases with groundwater information such as the Drinking Water System (DWS), the Permit to Take Water (PTTW) and the Water Well Information System (WWIS). A compilation of aquifer information from Source Protection (SP) reporting has been initiated for 29 of the 38 SP areas, all of the Great Lakes Basin region of Southern Ontario. Step one was to verify and confirm the cross indexing of wells reported in SP reports with the DWS, PPTW and WWIS databases. 898 municipal wells were identified and of these wells 96% were cross-indexed to the PPTW and 83% to the WWIS. Following well referencing information on 40 attributes in 7 groups was consolidated. Within this list of attributes information on aquifer names was also collected. Of 898 municipal wells tabulated, 334 wells are screened or terminated in bedrock with 9, in the contact bedrock-surficial sediment zone, and 555 wells in surficial sediment. A total of 163 aquifers were tabulated with 107 in surficial sediment, 10 in the surficial/bedrock contact zone and 46 in bedrock. Of the 163 aquifer names only 86 are unique names, with the remainder referred to as upper, lower, sand, gravel or coded with alphanumeric scheme such as A1, A2. Data extraction to date of aquifer parameter information is below 26% for all fields (e.g., thickness, K, T, porosity) forcing additional iterations and assessment of less accessible information related to municipal well installation reports etc.
