The dataset includes information about:

• the number and type of registered systems and laboratories
• drinking water quality test results
• adverse water quality incidents
• activities to support reduced lead in drinking water
• enforcement activities related to inspections
• orders and convictions
• system operator certification

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.

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.

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.

The Ontario Lake Partner Program (LPP) provides total phosphorus, chloride and calcium concentration data (as well as water clarity, when available) for hundreds of Ontario's inland lakes. The data are collected annually through volunteer monitoring efforts, known as community science. Engaging volunteers to take measurements and collect samples expands the geographic area monitored and fosters public interest in Ontario’s water quality and promotes lake stewardship. The Federation of Ontario Cottagers’ Associations (FOCA) has worked in partnership with the Ministry of the Environment, Conservation and Parks to collect this information.

MOOSE_AircraftRemoteSensing_NASA-G3_GCAS_Data contains remotely sensed data collected by the GEOstationary Coastal and Air Pollution Events (GEO-CAPE) Airborne Simulator (GCAS) onboard NASA's Gulfstream-III (G-3) aircraft during the Michigan-Ontario Ozone Source Experiment (MOOSE).

The Michigan-Ontario Ozone Source Experiment (MOOSE) is an international collaboration between US and Canadian agencies: the Ontario Ministry of Environment, Conservation, and Parks (MECP), the Environment and Climate Change Canada (ECCC), the US Environmental Protection Agency (EPA), and the Michigan Department of Environment, Great Lakes, and Energy (EGLE). These agencies conducted three field experiments to ensure a viable ozone attainment strategy which, due to their common goal, were given the common name MOOSE. The three field experiments that MOOSE encapsulates are: the Great Lakes Meteorology and Ozone Recirculation (GLAMOR) experiment, the Chemical Source Signatures (CHESS) experiment, and the Methane Releases from Landfills and Gas Lines (MERLIN) experiment. Field studies were conducted for MOOSE in 2021 and 2022. MOOSE consists of two phases, with the first occurring over six weeks from May to June 2021, and the second phase occurring during the summer of 2022. Both airborne and ground instruments are used in completing the campaign’s main goal of aiding in the creation of an ozone attainment strategy for Southeast Michigan (SEMI). SEMI is currently designated as in-marginal nonattainment of the U.S. federal ozone standard. The campaign also has the goal of better understanding what contributes to elevated ozone levels in the Border region, the immediate area on both sides of the US-Canada border. Along with understanding the contributing factors of elevated ozone levels, the campaign aims to understand how the elevated ozone levels cause exceedances to the Canadian ambient air quality standard for ozone.

In addition to MOOSE’s overarching goals, GLAMOR, CHESS, and MERLIN have their own objectives to fulfill. GLAMOR seeks to understand and simulate complex 3D flows that are associated with lake breeze circulations, the urban heat island (UHI) and its interaction with the lake breeze, and the impact of lake breezes and the UHI on ozone and ozone precursor transport. GLAMOR also aims to understand and track the influence of urban emissions and land-lake breezes on urban oxidative capacity through nitrous acid (HONO) and related reactive nitrogen species. Determining the conceptual picture (mesoscale meteorological patterns and photochemical production locations) for ozone exceedances in the Border region is what this campaign aims to achieve as well. Finally, GLAMOR aims to select representative ozone episodes for each identified mesoscale pattern, as well as conduct modeling and data analyses in support of an ozone attainment demonstration. The second sub-experiment, CHESS, has a goal to characterize the ozone precursor signatures at the key monitoring stations in the Border region where design values are highest during ozone exceedances in the typical year. CHESS will characterize emission plumes from point sources, area sources, and major industrial sectors in the Border region as well as their impacts on ozone design values on the two sides of the U.S. and Canada border. CHESS also aims to perform air quality model simulations of potential emission control strategies. The third sub-experiment, MERLIN, seeks to determine the natural gas leakage rate of pipelines or other infrastructure in SEMI. Quantifying methane, formaldehyde, and other emissions from landfills in the Border region as well as determining the contributions of large methane sources to ozone exceedances in the Border region are the two other objectives MERLIN is set to accomplish. In doing this, potential control strategies of gas emission into the atmosphere can be drafted and implemented.

The three sub-experiments are equipped with their own payloads and stations where research is conducted. GLAMOR uses ground stations and Aerodyne Networks to gather data from MECP’s Windsor West air monitoring station in Ontario, EGLE’s Detroit East 7 Mile PAMS Station, EGLE’s Port Huron monitoring station, as well as collecting field measurements of concentration and isotopic composition of NOx, HONO, NO2, HNO3, and NO3. CHESS utilizes mobile labs, ground stations, and the NASA Gulfstream III (G-III) aircraft while working with the Aerodyne Mobile lab, University of Michigan Pollution Assessment Lab (MPAL), and MECP Mobile Lab. CHESS utilizes these tools and payloads to measure CH4, HCHO, CO2, CO, H2O, O3, SO2, and NOx. MERLIN utilizes mobile labs, drones, and ground stations to work with the University of Michigan Mobile Lab, the Colorado State University Mobile Lab, and the EPA mobile lab. Drone-mounted meteorological chemical sensors for CH4, CH2O, and O3 precursors as well as the EPA GMAP mobile platform are used to measure hydrogen sulfide, methane, benzene, toluene, ethylbenzene, m-o-p xylene, and ozone, as well as meteorological parameters.

Part of the Wastewater Surveillance Initiative supported by the Ontario Ministry of Environment Conservation and Parks. Sequencing of Sars-CoV-2 in Ontario municipal wastewater for analysis to determine VOC/VOI frequencies present in the populations contributing to the wastewater. Results of analysis are reported to public health agencies from which the wastewater samples came. This information is used to inform policy and populate public facing dashboards. The raw sequencing data has also been used to develop and test bioinformatic tools. Some samples are sequenced for other viral targets such as ToBRFV, Influenza, or RSV. Shotgun metagenomic sequencing has been performed on a subset of the samples from this program as well. Funding for the project received by MECP, Health Canada and PHAC.
