The Provincial Groundwater Monitoring Network (PGMN) datasets report on ambient (baseline) groundwater level and chemistry conditions. Groundwater monitoring map

A source water assessment identifies the vulnerability of the drinking water supply to contamination from typical human activities. The assessments are intended to facilitate and provide the basic information necessary for a local community to develop a program to protect the drinking water supply.

Data on physical conditions in Ontario’s lakes and streams:

• For lakes this includes measurements such as temperature, dissolved oxygen levels and water transparency, ice dates, as well as sampling location details.
• For streams this includes measurements such as stream flow discharge from monitoring stations in south-central Ontario.

Meteorological conditions for climate stations close to monitored lakes in south-central Ontario, includes measurements such as air temperature, humidity, precipitation and wind speed.

This data set includes information on sampling locations and physical conditions in lakes and streams across Ontario, as well as meteorological and lake ice-cover conditions from monitoring stations in south-central Ontario. Data were collected since 1976, as part of routine monitoring of water quality of inland waters and for scientific and research purposes.

The water level data comes from the Provincial Groundwater Monitoring Network (PGMN) of Ontario. Each well in the observation network is equipped with a hydrostatic pressure transducer and a temperature sensor connected to a data logger. A second pressure transducer located above the water surface allows for adjusting the water level according to atmospheric pressure variations. The time series refers to the level below which the soil is saturated with water at the site and at the time indicated. The water level is expressed in meters above sea level (MASL). Groundwater levels are recorded hourly. The dataset consists of a general description of the observation site including; the identifier, the name, the location, the elevation, and a series of numerical values designating the water levels at a defined date and time of measurement.

The map shows the location of the six hydrogeological regions in Canada and the location of observation wells. The terrain composition is also shown on the map, which includes crystalline rocks, mixed crystalline rocks, folded sedimentary rocks and flat lying sedimentary rocks. The southern limit of continuous permafrost zone and the limit of the discontinuous permafrost zone appear on the map. Canada has been divided into six hydrogeological regions on the basis of similarities of geology, climate, and topography. These six hydrogeological regions are (1) the Appalachians, covering the area of New Brunswick, Prince Edward Island, Nova Scotia, Newfoundland, and the Gaspé and Eastern Townships of Quebec; (2) the St. Lawrence Lowlands, covering Anticosti Island, the extreme southern area of Quebec, and the southern part of Ontario; (3) the Canadian Shield, lying north of the St. Lawrence Lowlands and extending northward to a line joining the north end of Lake Winnipeg to Anticosti Island; (4) the Interior Plains, lying approximately south of the southern limit of discontinuous permafrost and consisting largely of the southern prairie regions of the provinces of Manitoba, Saskatchewan, and Alberta; (5) the Cordilleran Region, the mountainous part of western Canada within British Columbia; and (6) the Northern Region, approximately covering the area north of the southern limit of discontinuous permafrost. To monitor the groundwater flow systems and fluctuations in these hydrogeological regions a series of groundwater observation wells and piezometers have been established in various parts of Canada, as is shown on the map. The groundwater observation well map indicates the extent of provincial observation well and piezometer networks in Canada. Because of scale limitations, the symbols on the map may indicate more than one well. These wells and piezometers have been established in the southern part of Canada to monitor groundwater fluctuations and may also be used to monitor groundwater quality. Since this region of Canada has the largest population density, groundwater is of more immediate interest here. In the areas of discontinuous and continuous permafrost little has been done at present to monitor groundwater conditions, although this is changing as mineral exploration looks north for new reserves.

Volumes of water taken daily and annually under a Permit-to-Take-Water, as reported to the ministry under the Water Taking and Transfer Regulation 387/04.

The Ontario Water Resources Act (Act) requires anyone who takes more than 50,000 litres of water in a day to obtain a Permit to take Water (PTTW) with some exceptions. Under the Act, the Water Taking and Transfer Regulation requires all holders of a PTTW to report the volume of water taken at each permitted source for each day of water taking. The data includes information from the permit on the purpose of the water taking, water source types and locations, as well as the daily and annual volume of water taken from each source.

A study was conducted to provide detailed mapping of glacial aquifers associated with the Fairport-Lyons channel system in Wayne, Ontario, and Seneca Counties, New York. The study was part of the cooperative Detailed Aquifer Mapping Program between the U.S. Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The objective of the study was to characterize the hydrogeology of the Fairport-Lyons channel and inter-drumlin aquifer system and to present the results as an electronic 1:24,000 scale map, hydrogeologic sections, and a summary report. The spatial extent and hydrogeologic framework of this valley-fill aquifer was delineated using existing data, including soils maps, well records, geologic logs, topographic data, and published reports. This data release contains digital datasets for the areas of surficial sand and gravel with water-resource potential, eskerform features, areas of sand and gravel or sand pits, delineated areas of postglacial and glacial deposits, and records of selected wells within the study area and traces of the hydrogeologic sections referred to in the study. These digital datasets support USGS SIR 2021-5086, "Hydrogeology of aquifers within the Fairport-Lyons channel system and adjacent areas in Wayne, Ontario, and Seneca Counties, New York."

The Provincial Groundwater Monitoring Network (PGMN) is a partnership program between the Ontario Ministry of the Environment, Conservation and Parks and the province’s Conservation Authorities, as well as some municipalities in areas not covered by a Conservation Authority. There are almost 400 wells monitored across the province. The PGMN program began in 2000 and is designed to monitor ambient groundwater level and chemistry conditions across Ontario. Toronto and Region Conservation Authority (TRCA) is responsible for maintaining the digital telemetry systems at 21 monitoring wells in our jurisdiction, collecting water level data and arranging for chemical analyses of water quality samples at dedicated wells. This dataset includes water level observations for PGMN monitoring wells located within TRCA’s jurisdiction, including: seven wells in the Oak Ridges Moraine Aquifer Complex, five in the Thorncliffe Formation, six in the Scarborough Formation, one in the Lower Newmarket Till, and one in a bedrock unit. Wells are identified by PGMN Well No., coordinates, and aquifer.

This layer comprises all the available water wells in GIN (Yukon, British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland and Labrador) and published through the open data platforms. This layer is a combination of all individual provincial and territorial layers. The original databases are dynamically converted by an automatic process managed by Natural Resources Canada (Groundwater Information Network).

Last data update: March 14, 2017A polygon layer identifying areas where human activity may be contributing to poor water quality in a municipal well or surface water intake.Issue Contributing Areas are identified though groundwater modelling exercises undertaken by consultants, where required. Each individual ICA has a technical report outlining their processes.

Under the Clean Water Act, when a parameter in a municipal well exceeds an Ontario Drinking Water Standard, or is trending towards and exceedance, an "Issue" is declared. An Issue Contributing Area is that part of the landscape where anthropogenic activity is believed to be contributing to the exceedance.

The Source Water Protection Information Atlas is compiled by the Ontario Ministry of the Environment,Conservation and Parks (MECP) to display data on source water protection and vulnerability from Ontario's Conservation Authorities, including the Severn Sound Environmental Association and Municipality of Northern Bruce Peninsula, as well as Ontario parcel data from the Ontario Ministry of Northern Development, Mines, Natural Resources and Forestry.Search a location to see if it is in a vulnerable area – that is, close to a municipal drinking water well or other drinking water intake. In these areas certain land or water activities, if left unchecked, could pollute the water supply. If your location is in a vulnerable area, follow the link to the Help section, identify the threats for the zone, check the policy tab and if needed go to the source protection plan to find out what activities are prohibited or need to be managed.You may also follow the link to the Threats Tool, in the Help section to identify what activities pose a threat to drinking water sources in the zone.

From July through November 2018, 48 environmental samples and four quality-control samples were collected throughout the Lower Hudson, Chemung, and Eastern Lake Ontario River Basins. Samples were collected from seven production wells and eight domestic wells in the Eastern Lake Ontario Basin, 13 production wells and 12 domestic wells in the Lower Hudson River Basin, and four production wells and four domestic wells in the Chemung River Basin. Of the wells sampled, 27 were completed in bedrock and 21 were completed in sand and gravel. Approximately 20 percent of samples were collected from wells that were previously sampled in 2003, 2008, and 2013. Groundwater samples were collected prior to any treatment or filtration systems, from existing domestic and production wells equipped with permanently installed pumps.
Samples were collected and processed using standard USGS methods and were analyzed for 372 constituents including physicochemical properties, dissolved gases, major ions ...

Shows areas of influence on the land around a municipal well, the size of which is determined by how quickly water travels underground to the well, measured in years. For source protection planning, the Clean Water Act required that a standard 100 metre radius circle be provided around each municipal well; that is called the WHPA-A. The WHPA-B represents the 2-year time of travel. The WHPA-C represents the 5-year time of travel and the WHPA-D represents the 25-year time of travel.The shape of the WHPAs is based on numerical hydrogeological modelling results for all of the York Region production wells and are dynamic to some degree, since they can be influenced by a number of factors such as the slope of the land, the depth of the well, and the type of sediment. The maps that this data is based on have supporting reports that discuss their development and are available via the Water Resources group.Please refer to the Clean Water Act approved symbology when using this data.
