Data and sources
WellAtlas adds one government dataset at a time. A province or territory shows as covered only once its dataset has actually been imported.

The licence lets anyone copy, adapt and redistribute these records, including commercially, on one condition: that the attribution above is shown. It is shown on every well record in the apps, and here. The licence is granted by the Government of Ontario to everyone, not to us — if you want the records themselves, take them from the catalogue link above under that same licence. You do not need our permission.
What is removed before the records reach the app
Public does not mean republishable. These columns are dropped during import, not hidden in the interface, so they never reach a server the apps talk to:
- Owner name — the item Ontario itself withholds under FIPPA.
- Street address — a civic address beside a precise coordinate identifies a household.
- Site description — uncontrolled free text that can describe a private property and cannot be reviewed row by row.
- Contractor licence number — it identifies an individual licensee and no feature needs it.
- Free-text comment columns, as a class.
Coordinates, lot and concession and municipality are kept. Ontario publishes the same coordinates on its own public map, the record describes a structure rather than a person, and no name survives the import to join a coordinate to.
Known limitations
The publisher's own use limitation, quoted from the dataset's metadata record:
There are inaccuracies in terms of location and other information. Some of the inaccuracies are inherited directly from the person who completed and submitted the well record. Inaccuracies may also be introduced during data entry.
What the import measured, from the source review of release 2026a:
- Only 3,307 of 1,022,416 records — about 0.3% of Ontario records have a location measured to within 10 m. The strictest accuracy class alone accounts for 825 records.
- 200,977 records carry an unknown location accuracy.
- 51,300 records have no coordinates at all and never appear on the map.
- 647 records fall outside Ontario. They are flagged, not removed — the app does not quietly delete rows from a government record.
- Depth to bedrock comes from the published GIS layer rather than the database release, where that column is empty.
- Records include wells constructed from 1899 onward; most were received after the 1940s.
- Free-text comments are never shown, because they are never imported.
Found something wrong in a record?
WellAtlas does not edit government records, so a correction has to be made at the source. If a record is wrong, report it to the Government of Ontario through the dataset's catalogue page; corrections reach the app with the next dataset release. If the app is showing a record differently from the source, that is ours — tell us.

The licence is granted by the Government of Alberta to everyone, not to us — if you want the records themselves, take them from the catalogue link above under that same licence. You do not need our permission. The publisher confirmed in writing on 29 September 2026 that the database download is published under this licence, commercial use included.
What is removed before the Alberta records reach the app
Alberta's download is not a redacted release: it includes names and addresses. These are dropped during import, not hidden in the interface, so they never reach a server the apps talk to:
- Owner names and addresses — the whole table that holds them is never opened.
- Driller names and journeyman numbers, and drilling companies' names, addresses and e-mail — the three tables that hold them are never opened.
- The keys that point into those tables — they would identify the owner or the licensee even without the tables.
- Free-text columns, as a class — comments, location descriptions, where drilling water was taken from, pump models and the like.
Coordinates, legal land descriptions (legal subdivision, section, township, range and meridian, or lot, block and plan), the well tag number and construction details are kept. Alberta publishes the same coordinates on its own public map and searches by the same land descriptions in its own application, the record describes a structure rather than a person, and no name survives the import to join a coordinate to.
Known limitations of the Alberta records
The publisher's own caution, quoted from the database's download page:
Data provided through this website are preliminary in nature. This data may not have been reviewed or edited for accuracy and may be subject to significant change when reviewed or corrected.
What the import measured, from the source review of release 2026-09-26:
- 371,519 of 453,712 records (82%) are plotted at the centre of the parcel their land description names — most often a quarter section or a legal subdivision — not where the well is. They are labelled approximate, with an accuracy of 285–1,138 m derived from the size of the parcel.
- Only 846 records are survey-grade, and another 11,255 are located to within 10 m.
- 56,609 records carry an unknown location accuracy.
- Every record has coordinates, and none falls outside Alberta. The publisher confirmed that they are in NAD83; the download itself does not say.
- The download does not include the publisher's decommissioning tables. 60,822 records are marked decommissioned because a report in the download says so; a record that does not say a well was decommissioned does not mean the well is still in use, and the app never says that a well is active. The publisher has said it intends to add those tables in new download files.
- Depth to bedrock is not reported by the source.
- 32,951 static water levels were measured from the top of the casing rather than from the ground, and are shown as reported.
- No municipality or county is recorded, so municipality search and the site's municipality pages do not cover Alberta.
- Free-text comments are never shown, because they are never imported.
Found something wrong in an Alberta record?
WellAtlas does not edit government records, so a correction has to be made at the source. If a record is wrong, report it to the Government of Alberta's Groundwater Information Centre, whose contact details are on the database's catalogue page; corrections reach the app when a later daily rebuild is imported. If the app is showing a record differently from the source, that is ours — tell us.

Contains information licensed under the Open Government Licence – British Columbia.
The licence lets anyone copy, adapt and redistribute these records, including commercially, on one condition: that the attribution above is shown. It is shown on every well record in the apps, and here. The licence is granted by the Province of British Columbia to everyone, not to us — if you want the records themselves, take them from the catalogue record or the application above under that same licence. You do not need our permission. The ministry confirmed in writing on 6 October 2026 that the export WellAtlas imports is covered by this licence, in answer to a question that named redistribution in a commercial application.
What is removed before the British Columbia records reach the app
The export carries no owner names, but it does carry addresses, other people's names and free text. These are dropped during import, not hidden in the interface, so they never reach a server the apps talk to:
- Street addresses and location descriptions — a civic address or a note such as where the well sits in relation to the house identifies a household.
- Names of drillers, consultants and the person responsible for the well report, and their companies — they identify people and their businesses.
- Comments and all other free text, as a class — including the drillers' own descriptions of the ground they drilled through. That is why most lithology intervals in the apps show depths but no material: only the coded material is kept, and most intervals have none.
- Owner columns, pre-emptively — the export has none today. Should one be added, it is dropped, and any new column stops the import before anything is loaded.
Coordinates, the town, the legal description (lot, plan, district lot, block, section, township, range and land district), the parcel identifier (PID), the well tag and identification plate numbers and the dates are kept. The Province publishes the same data in its own GWELLS application, and the coordinates also in its licensed catalogue layer; GWELLS's own search takes a PID; the record describes a structure rather than a person; and no name survives the import to join a coordinate to. Keeping the PID was an explicit decision of the source review: it is the most direct link from a well to a land-title record, but that link already exists in the Province's own publication. Town values that hold a postal code or an e-mail address are dropped whole.
Known limitations of the British Columbia records
The publisher's own caution, quoted from the statistics file in the export:
The Groundwater Wells and Aquifers application may not include all groundwater wells as registration with the Province was voluntary until February 2016.
What the import measured, from the source review of release 2026-10-06:
- 23,876 of 133,080 records (18%) are plotted at the centre of their parcel, not where the well is. They are labelled approximate, with an unknown accuracy.
- 2,154 records have no coordinates at all and never appear on the map.
- One well is placed by the source about 1.2 km south of the 49th parallel, in Washington State. It is shown where the source places it and is not flagged.
- Coordinates are in NAD83, as the ministry confirmed on 6 October 2026; the difference from WGS84 is under 2 m.
- The source is ambiguous about what static water levels are measured from: the export's column and the GWELLS well page say below the top of the casing, the publisher's data model says below the ground. Levels are shown as reported.
- 603,780 of 642,125 lithology intervals (94%) have depths but no material, because the driller's free-text description is not imported.
- 10,229 construction dates are placeholders (1 January 1950 on legacy records, and 1 January 1900 and 1901) and are shown as no date; 11,357 are known to the year only.
- The municipality is the town written on the well report, in 5,415 different spellings; it is not an administrative boundary, and one town can appear under several spellings.
- Every yield is in US gallons per minute, as the ministry confirmed on 6 October 2026, and is converted to litres per minute. The export also carries a yield unit code; the ministry describes it as a retired field, and the importer ignores it.
- Free-text comments are never shown, because they are never imported.
Found something wrong in a British Columbia record?
WellAtlas does not edit government records, so a correction has to be made at the source. If a record is wrong, report it to the Province of British Columbia through the contact given in the GWELLS application or on the catalogue record; corrections reach the app when a later nightly export is imported. If the app is showing a record differently from the source, that is ours — tell us.

The licence lets anyone copy, adapt and redistribute these records, including commercially, on one condition: that the attribution above is shown, with a link to the licence where possible. It is shown on every well record in the apps, and here. The publisher gives no attribution statement of its own for this dataset, so the licence's default sentence is used. The licence is granted by the Government of Prince Edward Island to everyone, not to us — if you want the records themselves, take them from the catalogue record above under that same licence. You do not need our permission. The source review read the live licence page on 8 October 2026: version 1.0, published 30 May 2018.
What is removed before the Prince Edward Island records reach the app
The table has no owner name, address, telephone or e-mail column. What it does carry about people, and its free text, is dropped during import, not hidden in the interface, so it never reaches a server the apps talk to:
- The drilling contractor — the column names drilling businesses, and individuals among them.
- The well-name and well-field columns — free text. The first is empty in this release; both are dropped so that a later release cannot carry a name into the app.
- Redundant columns — two further copies of the coordinates and the row number the hosting service assigns.
- Owner and contact columns, pre-emptively — the table has none today. Should one be added, it is dropped, and any new column stops the import before anything is loaded.
Coordinates, the community, the parcel identifier (PID), the record number, the date and the measurements are kept. The Province publishes the same table, coordinates and PID included, under an open licence; the record describes a structure rather than a person; and no name survives the import to join a coordinate to. Keeping the PID was an explicit decision of the source review. Joined with the Province's property records it leads to the owner of the parcel, and unlike British Columbia the Province offers no search by PID of its own; but it is the publisher's own column in an openly licensed table, and the only land description Prince Edward Island publishes for a well.
Known limitations of the Prince Edward Island records
The publisher's catalogue entry describes the table in one sentence and documents none of its columns beyond their names and units: no definitions, no datum and no history.
What the import measured, from the source review of release 2026-05-27:
- No well type, status, use or construction method is published. All four read
not reported
for every Prince Edward Island well, so filters on them find none. - Every zero measurement is read as not reported, including 1,011 static water levels and 1,740 yields. Most were keyed before about 2000, when a blank was apparently entered as a zero, and the publisher does not say what a later zero means.
- 1,067 of 31,360 records (3.4%) have no coordinates at all and never appear on the map.
- 23 records are placed by the source outside the island, most in New Brunswick or Nova Scotia. They are flagged, not moved.
- 894 records sit on points shared by records from two or more communities. These are placeholder locations, not wells, and are labelled approximate.
- No location method is recorded. Only 265 records have an accuracy, derived from the number of decimal places the source publishes: 112 within 100 m, 138 within 300 m and 15 coarser than 1 km. The other 31,095 (99%) carry an unknown location accuracy.
- The datum of the coordinates is not stated by the publisher; they are taken as given, without a transformation. NAD83 and WGS84 differ by less than the data's precision.
Charlottetown
is a default value in the source's community column. On 10,710 records placed more than 10 km from the city, or not placed at all, it is removed and the municipality is left blank. Some of the 2,756 kept within 10 km are the same default on wells in neighbouring municipalities, which the distance cannot tell apart.- 593 records carry no record number. They get an identifier derived from their content and are marked as limited records. 569 records repeat another record apart from the number; they are flagged as possible duplicates, not merged.
- The source does not say whether its date marks the completion of drilling or the receipt of the report. It is shown as the date on the well record.
- 40 implausible diameters (20 to 120 inches), one yield and one static water level are not shown.
- Free text is never shown, because it is never imported.

Contains information licensed under the Government of Saskatchewan Standard Unrestricted Use Data Licence (Version 2.0). Source: Water Security Agency, Water Well Driller's Reports (Water Wells, Public).
The licence lets anyone copy, adapt and redistribute these records, including commercially, on one condition: that the attribution above is shown, with a link to the licence where possible. It is shown on every well record in the apps, and here. The agency gives no attribution statement of its own, so the licence's default sentence is used, followed by the source. The licence is granted by the Government of Saskatchewan to everyone, not to us — if you want the records themselves, take them from the catalogue record above under that same licence. You do not need our permission. The source review read the licence on 28 September 2026 (version 2.0, approved 18 January 2018), and on 29 October 2026 the agency confirmed in writing that the licence named on its catalogue record also covers the live map service the records are read from. The licence grants no right to personal information, which is one of the reasons the owner's name is never requested (next section).
What is removed before the Saskatchewan records reach the app
The agency's layer carries the well owner's name — its own report form labels the field
Well Owner Name
— and the drilling company. WellAtlas never receives either. The
importer asks the service for a fixed list of fields by name, and a reply that carries a field
it did not ask for is refused whole, so these columns are not dropped after the fact: they are
never transferred. The same applies to:
- The hole-number field — eight characters of free text that is usually a test-hole sequence but can be a word, a place or a person.
- The agency's map viewer and its catalogue downloads, which show or carry the owner's name. They are never read, and no Saskatchewan record links to a page at the agency.
- Owner and contact columns, pre-emptively — any new or renamed column stops the import before a single record is requested.
The report number, the coordinates, the legal land description, the dates, the construction details and the measurements are kept. The agency publishes the same points on every copy of the layer; the record describes a structure rather than a person; and no name survives the import to join a coordinate to. Keeping the land description was an explicit decision of the source review: it is how Saskatchewan refers to a well, it names a quarter section whose owner is already public in the land titles, and it adds nothing the point does not show — most points being the centre of that quarter, not the well (next section).
Known limitations of the Saskatchewan records
Three come from the agency's own description of the layer, in its words. The data
has not been field-verified
and use of, and reliance upon, the data is at the
user's own risk
. The dataset does not contain all of the wells in the Province, only
those that have been reported by drillers
. And most of the point features are located
at the centroid of the quarter section which they fall within; the actual location in the
real world could be anywhere in that quarter section
.
What the import measured, from the source review of release 2026-10-29:
- Most points are not the well. 141,492 records (95%) sit at the centre of the survey unit the driller reported, and are labelled approximate: 5,387 legal-subdivision centroids within 300 m, 124,531 quarter-section centroids within 1,000 m, and 11,753 section, township, river-lot and reserve centroids coarser than that. 4,342 records carry a GPS position, within 100 m, and 2,585 an unknown accuracy. The 148,598 records sit on 79,799 distinct points; up to 174 share one.
- 181 records were recorded in UTM zone 12 but stored as zone 13, some 400 km east of the quarter section they name; they are placed where the zone-12 reading puts them and labelled approximate, the stored values kept. 559 records lie far from the land description they state; they are left where the agency puts them, with an unknown accuracy.
- The static water level is measured from the top of the casing on a completed well (68,798 records) and from the ground on an uncompleted hole (7,369), the agency's own rule; the datum is recorded on each record and the level is shown as reported, not adjusted (78,005 levels in all).
- Zero means
not reported
in every measurement column, the pumping rate included: 1,363 records have no depth, 70,593 no static level and 84,822 no pumping rate. All units are imperial as published — feet, inches and imperial gallons a minute — and converted; none is inferred. - 3,269 wells flow at the surface: 1,925 with a measured head above
ground and 1,344 whose head was not measured (a
999
in the source, which the agency confirmed means exactly that). - No lithology, no depth to bedrock and no water quality are published, so no Saskatchewan well has a material log, and 65,563 of 148,598 records are marked as limited records under the rule that counts missing fields. No record names a municipality — the rural municipality is a number — which is why this site has no Saskatchewan municipality pages.
- Test holes (46,005: water, seismic, soil and mineral) and monitoring wells (3,767) are included and typed, so they can be filtered out.
- The well's status is almost never stated: 734 wells are decommissioned,
every other one reads
not reported
. - 3,819 records carry no completion date, and 6,366 a year only (a date of 1 January or 1 July before 1990 is read as year-only, as the agency's data entry used it).
- 2,030 records report a casing or a water level below the well's own depth; both values are shown as reported and marked. 1,051 records carry a measurement rejected as implausible — a depth over 5,000 feet, a diameter over 48 inches and the like — which is not shown. 177 pairs of records share a measured point and a completion date and are marked as possible duplicates.
- Free text is never shown, because it is never imported.
Found something wrong in a Saskatchewan record?
WellAtlas does not edit government records, so a correction has to be made at the source.

The licence lets anyone copy, adapt and redistribute these records, including commercially, on one condition: that the attribution above is shown, with a link to the licence where possible. It is shown on every well record in the apps, and here. The publisher gives no attribution statement of its own for this dataset, so the licence's default sentence is used. The licence is granted by the Government of Yukon to everyone, not to us — if you want the records themselves, take them from the catalogue record above under that same licence. You do not need our permission. The source review read the licence page on 8 October 2026: version 2.0, last modified 16 July 2025. Every download also carries the publisher's 2014 data disclaimer, which disclaims warranties and adds no condition of use.
What is removed before the Yukon records reach the app
The download has no owner, driller, company, telephone or e-mail column. What it does carry about people, and its free text, is dropped during import, not hidden in the interface, so it never reaches a server the apps talk to:
- The well-name column — a free-text label that, for private wells, is mostly the civic address or the lot number. Site, business and project names are in the same column; it is dropped whole.
- The quality notes — free text, some of it repeating an address or a lot.
- The links to scanned drillers' logs and consultants' reports — the publisher's scans can show an owner's name and mailing address. They are never fetched, stored, linked or displayed.
- Owner and contact columns, pre-emptively — the download has none today. Should one be added, it is dropped, and any new column stops the import before anything is loaded.
Coordinates, the community, the borehole identifier, the dates, the purpose and the measurements are kept. The territory publishes the same points in every one of its downloads and on its own map; the record describes a structure rather than a person; and no name or address survives the import to join a coordinate to. Keeping the borehole identifier was an explicit decision of the source review: it is the registry's own public number, written on the forms, and without it a well cannot be cited, searched by number or matched to a later release. The publisher itself publishes that number beside the address of the well's scanned log; WellAtlas never builds, stores or shows that link.
Known limitations of the Yukon records
Two come from the publisher's own catalogue entry, in its words. The registry is not
complete: there is no current overarching requirement for drillers or owners to submit well
logs
, so many have been provided on a voluntary basis
and the dataset is not a
complete list of all wells across the territory
. And a record
documents the original drilling conditions
, not an updated status of the well
.
What the import measured, from the source review of release 2026-10-07:
- Every yield's gallon is assumed. The source gives yields in
gal/min
without saying which gallon; they are read as imperial and marked as an inferred unit on all 1,041 stored yields (32% of wells). If the gallon is US, every Yukon yield shown is 20% too high. - Static water levels are measured from the top of the casing, not the ground, and are shown as reported (1,318 wells).
- Bedrock is mostly
not reached
: 1,786 wells say only that bedrock lies deeper than a stated depth, usually the well's own; 791 give a depth to bedrock, and 17 zeros are read as not reported. - No lithology is published, so no Yukon well has a material log, and 2,030 of 3,244 records are marked as limited records under the rule that counts it.
- The well's status is almost never stated: 3 wells are inactive, every other

. - Monitoring wells (878), geotechnical boreholes (238) and test wells (177) are included and typed, so they can be filtered out.
- No location accuracy in metres is published. It is classed from the publisher's stated location method: 138 records placed by survey or differential GPS are within 10 m, 1,292 placed by handheld GPS within 100 m, 1,718 placed from imagery within 300 m, and 96 carry an unknown accuracy.
- 286 records sit on 104 points shared by several wells of one site. They are labelled approximate. 3 records lie just south of 60° N, in British Columbia, where the registry places them; they are flagged, not moved.
- 719 records carry no drilling date.
- 11 implausible elevations, 4 casing heights, 5 yields above 1,000 gallons a minute and 5 screens whose bottom is above their top are not shown.
- Free text is never shown, because it is never imported.
Found something wrong in a Yukon record?
WellAtlas does not edit government records, so a correction has to be made at the source. If a record is wrong, report it to the Government of Yukon through the contact given on the catalogue record; corrections reach the app when a later copy of the file is imported. If the app is showing a record differently from the source, that is ours — tell us.
