| The Saint-Maurice Aquifer delineation was made by using the Quaternary Geological maps. The fallowing units were extracted:
At: river terraces, alluvium: sand, silty sands, organic gravel-sands and gravel; thickness 0.5 to 5 meters.
Ld: River delta: sand, gravel-sands and gravel, laminated and well-sorted; thickness 1 to 20 meters; these were formed at the end of water courses flowing into the Lampsilis lake; forming plane bedding.
Md: River delta: sand, gravel-sands and gravel, laminated and well-sorted; thickness: 1 to 40 meters; these were formed at the end of water courses flowing into the Champlain sea; locally including sediments. The resulting polygons were merged to delineate the Saint-Maurice aquifer zone.The aquifer's potential is not yet established. |

| This map represents the key aquifers in Canada, as defined by the Groundwater Mapping Program of the Geological Survey of Canada. This map illustrates the delineation of known aquifers and aquifers that were studied in the course of the groundwater program, the groundwater potential of the aquifers are indicated. |
| This map was created to provide a national framework representing the coverage of the key aquifers of Canada. It was created by integrating various internal and external data sources coming from provincial agencies, watershed agencies and universities. General lineage data on this map comes from the compilation of multiple data sources. The delineation of some aquifers required the digitization or transformation of information from various documents, maps or reports. |

| Delineation of the Carbonate rock Aquifer was made by merging information from three different sources. The main geological formation located in Manitoba was defined by scanning the polygon representing the Carbonate Rock, found on the map: Aquifer Maps of Southern Manitoba; www.gov.mb.ca/waterstewardship/floodinfo/maps/images/bed_rock_aquifers.jpg. The boundaries of the formation under the Winnipeg lake was not illustrated on the map (except for the islands), the eastern limit under the Winnipeg lake was then arbitrarily established at the lake shore. This limit will eventually have to be revised. The Carbonate rock unit located in Saskatchewan was established by scanning the figure on page 21 of the document J.W. Pomeroy and al. |

| The Gulf Islands Fractured Aquifer was delineated using two merged data sources. The polygons representing the aquifer were extracted from the corresponding files on the National Hydro Network (www.geobase.ca). These polygons represent the "Islands" identity class of the National Hydro Network.
To limit the aquifer's boundaries the polygons were segmented according to the productivity factor found on the Ground Water Aquifers map. Correspondence between aquifer productivity and potential was establish by associating high and moderate productivity to a high potential aquifer and a low productivity to a low potential aquifer. Certain Gulf Islands aquifers productivity were not defined on the Ground Water Aquifers map, their aquifer potential was then arbitrary establish to low.
To simplify the mapping process the polygons representing aquifers with equal potential were merged. |

According to the physiographic unit defined by K. Ronneseth, W. Hodge, and A. P. Kohut, the Nanaimo Lowlands elevation is below 600 meters.
The Ground Water Aquifers map shows three productivity levels (high, moderate, low).
Correspondence between aquifer productivity and potential was establish by associating high and moderate productivity to a high potential aquifer and a low productivity to a low potential aquifer.

| Delineation of the Fraser Lowlands Aquifer was made by using the defined limits of the aquifers compiled in the Ricketts and Makepeace's Report.
The Ground Water Aquifers map that serves as a reference for aquifers productivity was used to determine the aquifer's potential by overlapping it with the predefined aquifer's limits.Three levels of productivity are designated on the Ground Water Aquifers map (high, moderate, low). Correspondence between productivity and potential was establish by associating high and moderate productivity to a high potential aquifer and a low productivity to a low potential aquifer.
The Fraser Lowlands Aquifer is considered a high potential aquifer. To simplify the mapping process the polygons representing aquifers with equal potential were merged. |

| The Odanah shale Aquifer was delineated using two different sources. The R. Betcher and al document was used to determine the Winnipeg formation's dimension. According to R. Betcher and al the Winnipeg formation starts at the centre south of Manitoba and ends west at the Saskatchewan frontier. The aquifer's boundaries were established by scanning the Odanah Shales polygons found on the Aquifers Maps of Southern Manitoba. The left corner large polygon was extended to the Saskatchewan's frontier while fallowing the international frontier as shown on the figure 14 in the R. Betcher and al's document. The formation's oriental limit (Saskatchewan frontier) is arbitrary. More data will be needed to establish the western boundaries. |

| The Chaudière Aquifer was delineated using the 02PJ000 watershed unit of the National Hydro Network. The Chaudière Watershed was extracted from The National Hydro Network (NHN) Work Unit Limit. The polygon created was larger then the studied field (meddle and lower part of the chaudière River Watershed) therefore the polygon was segmented.

| The Upper Thames Aquifer was delineated using the 02GD000 watershed unit of the National Hydro Network. The Upper Thames Aquifer watershed was extracted from The National Hydro Network (NHN) Work Unit Limit. The Aquifer zone corresponds to the polygon created by the extraction.
The Aquifer's potential is not yet defined. |

| Delineation of the Basal clastic unit (Winnipeg) Aquifer was made by merging the information of two different data sources. The Winnipeg formation was established with reference to the R. Betcher and al's document. The map: Aquifers Maps of Southern Manitoba, was used to delineate the aquifer by using the Winnipeg outcrops illustrated on the map. To determine the eastern limit, where there is no illustrated outcrops, the geological contact with the Canadian Precambrian Shield was used. The formation limit under the Winnipeg lake was not illustrated on the map (except for the islands), the eastern limit under the Winnipeg lake was then arbitrarily established at the lake shore. This limit will eventually have to be revised. The unit occidental limit was set arbitrary to the Saskatchewan's frontier. Delimitation of the salt water is provided by figure 9 of the document R. Betcher and al. |

| The Cornwallis-Annapolis Valley Aquifer was delineated by extracting files joint to the report Rivard and al., Canadian groundwater inventory, written by a team of the Geological Survey of Canada. According to this report the aquifer potential is defined in two classes (high and low). To simplify the mapping process the polygons representing aquifers with equal potential were merged. |

| The Milk River Aquifer was delineated using the 11AA001 unit of the National Hydro Network. The Milk River Watershed was extracted from The National Hydro Network (NHN) Work Unit Limit. Other data sources were analysed but not used: Hydrogeological map of the Lethbridge - Fernie area, Alberta, NTS 82G and NTS 82H, Hydrogeological map of the Foremost area, Alberta, NTS 72E, source: (http://www.ags.gov.ab.ca/publications/ABSTRACTS/MAP_105.html and http://www.ags.gov.ab.ca/publications/ABSTRACTS/MAP_110.html).
The Groundwater Divide could have been used to delineated the aquifer but a lack of information on the map would have required a large scale interpolation that would have invalidated the data. |

| The Portneuf fractured Aquifer located in the Portneuf Regional County Municipality was delineated using the Geological Survey of Canada files used to produce the regional Laurentien Piemont hydrogeologic information sheet. Two potential classes of aquifer were represented (high and low). The high class corresponds to the hydrological context 1A, 1B, 1C, 1D, 2 et 3 and the low class corresponds to the hydrological context 3, 4, 5, 6A, 6B, 6C et 6D. To simplify the mapping process the polygons representing aquifers with equal potential were merged. |
