Data is collected each year, according to the lake-by-lake cycle. Information includes: * water chemistry * approximately 60 index and reference stations throughout the Great Lakes basin

The outer boundary of the Greenbelt Area as defined by Ontario Regulation 59/05. The outer boundaries of Greenbelt area includes lands within the: * Niagara Escarpment Plan Area * Oak Ridges Moraine Area * lands designated as Protected Countryside * lands designated as Urban River Valley

Data is collected each year, according to the lake-by-lake cycle. Information includes: * sediment chemistry * approximately 60 index and reference stations throughout the Great Lakes basin

Provides stream water quality monitoring data for a number of parameters, including total and dissolved nutrients, metals, and chloride. The Provincial (Stream) Water Quality Monitoring Network (PWQMN) measures water quality in rivers and streams across Ontario. This dataset provides stream water quality monitoring data for a number of parameters, including total and dissolved nutrients, metals, and chloride. Spatial information for stream monitoring locations across Ontario are also available. [Stream water quality map](https://www.ontario.ca/environment-and-energy/map-provincial-stream-water-quality-monitoring-network)

The air monitoring stations measure up to 6 common pollutants like: * ground-level ozone * fine particulate matter * nitrogen dioxide * carbon monoxide * sulphur dioxide * total reduced sulphur compounds The Ministry of the Environment, Conservation and Parks continually monitors air quality across Ontario. We use this information to: * inform the public about outdoor ambient air quality through the Air Quality Index (AQI) and Smog Advisory program * assess Ontario's air quality and evaluate long-term trends * identify areas where pollutant levels are exceeded * identify the origins of pollutants * develop air policy * provide quantitative measurements to reduce specific pollution sources * determine the significance of pollutants from long-range transports and their effects * provide air quality researchers with data to link environmental and human health effects to air quality

The purpose of this dataset is to identify the location of river valley connections.

The Provincial Groundwater Monitoring Network (PGMN) datasets report on ambient (baseline) groundwater level and chemistry conditions. [Groundwater monitoring map](https://ontario.ca/environment-and-energy/map-provincial- groundwater-monitoring-network)

The Ministry of the Environment, Conservation and Parks started a project to characterize the number of species of bumble bees and the relative abundances of these species in southwestern Ontario in support of the Pollinator Health Action Plan. Bumble bees were collected from 46 locations to compare the diversity of bees occurring in agricultural and more natural areas. The data includes: * sampling locations, including GPS coordinates and the county name * the number of bumble bee individuals sampled at each site, listed for each species and for each caste of a species (queen, worker, male) * other site details, such as the date of the site visit [View this data on an interactive map](http://www.moegisportal.ca/agol/AccessibleViewer/index.html?appid=e38703b018ff4e3ca09f2878879a4e34) This dataset is related to the following: 1.

This dataset consists of information from reports received by the Spills Action Centre (SAC). They are generated and completed by SAC following the initial report of a spill. The data includes: * the reference number assigned to the spill * the municipality in which the spill occurred * what was impacted (e.g. land, water, air, or combination) * the substance being discharged (e.g. oil, gases, chemical, etc.) * whether the environmental impact is confirmed, possible, or not anticipated, and * the source/sector of the spill. The data reflects the information as reflected in the report, following the incident. All spills reported to SAC are recorded in the database, regardless of whether or not the Ministry provides field response.

135 locations from Killarney to Honey Harbour were surveyed between 2003 and 2005 (3 times a year representing spring, summer and fall conditions) across a spectrum of environments along the eastern coast of Georgian Bay. The purposes include to: * identify the range of natural variability in water quality conditions in the coastal areas * better understand the interactions between the watershed and the open waters of Georgian Bay on water quality * provide insight on the human effects on water quality This information is used to establish a baseline to which future water quality conditions can be compared and to identify the factor(s) responsible for variable water quality conditions.
