    The Air Quality in Ontario Report summarizes the state of ambient air quality in 2015 and 10 year trends for key airborne pollutants affecting Ontario's air quality.

  • Categories  

    The flows and effluent quality data is for the parameters of: * Biological Oxygen Demand BOD5/CBOD5 * Total Suspended Solids (TSS), also described as Residual Particulate Solids * Total Phosphorus (TP) * total monthly flow Keywords: Sewage, Effluent, Discharge, Watershed, Waterworks, Water management, Muncipality

    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

    Get data about the water quality for Ontario's inland lakes. The data is collected through volunteer monitoring efforts – citizen science. The [Lake Partner environment map](https://www.ontario.ca/page/map-lake-partner) The Lake Partner Program (LPP) measures water quality in inland lakes across Ontario. This dataset provides water quality and water clarity data, as well as data on the concentrations of: * total phosphorus * calcium Spatial information for lake monitoring locations across Ontario are also available. Keywords: Lake, Water, Citizen Science, Community Science, Volunteer, Phosphorus, Calcium, Chloride, Water Clarity

    The Lake Simcoe lake monitoring program provides measurements of chemical and physical water quality limits such as total phosphorus, nitrogen, chlorophyll a, pH, alkalinity, conductivity, dissolved organic and inorganic carbon, silica, other ions, water transparency, temperature and dissolved oxygen. Samples are collected biweekly during the spring, summer and fall. *[pH]: potential of hydrogen

    This data set includes information on sampling locations and physical conditions in lakes and streams across Ontario. It also includes meteorological conditions from monitoring stations in south-central Ontario. __Lakes__ The data for lakes includes sampling location details and measurements such as: * temperature (1976-2021) * dissolved oxygen levels (1976-2021) * water transparency __Streams__ The data for streams includes measurements such as stream flow discharge from monitoring stations in south-central Ontario. (1976-2019) __Meteorological conditions__ This dataset contains meteorological conditions for climate stations close to monitored lakes in south-central Ontario. It includes measurements such as: * air temperature (1976-2020) * humidity (1976-2020) * precipitation (1976-2020) * wind speed (1976-2020) Data were collected since 1976 as part of routine monitoring of water quality of inland waters and for scientific and research purposes.
