In rural Alberta, 90 per cent of people use private well water supplies for domestic use (e.g. drinking, cooking, bathing or cleaning). Domestic well water systems are not regulated by either the provincial or federal governments. The Government of Alberta along with Alberta Health Services provides water chemistry testing of private well water and information and advice on safe water for domestic purposes; however, it is the responsibility of private well owners to ensure the quality and safety of their water supply.

Water quality data is based around two of the largest lakes in Prince Albert National Park – Kingsmere and Waskesiu. Data is collected monthly from May through September each year, with additional water chemistry sampling in March. Water chemistry and Secchi disk depths are sampled by boat at three open water locations, and E.coli levels are tested from three high use beach locations. Discharge measurements are taken for Waskesiu Lake inflow (Kingsmere River, Mud Creek) and outflow (Waskesiu River).

This dataset includes water chemistry data for the La Salle River near Elie, Manitoba, Canada (Water Survey of Canada Hydrometric Station 05OG008) for the time period of 2009 – 2015. The data was collected for hydrological and water quality modelling as part of Agriculture and Agri-food Canada’s Red-Assiniboine Project. Chemical parameters include total dissolved nitrogen, total nitrogen, total dissolved phosphorus, total phosphorus, and total suspended solids. The frequency of data collected ranges from multiple samples per week during high discharge periods from 2013 to 2015 to weekly or sub-monthly frequency from 2009 to 2012 and during periods of low stream discharge.

This dataset contains an extract of water chemistry data from the Cold Lake - Beaver River Basin project area. The work was completed in 2004 under contract to Alberta Environment (AENV). Information was obtained from industry and government sources. These data are available in three text files, each representing one table in the original database.

Water quality is a globally accepted and widely used measure for assessing and monitoring the condition of freshwater ecosystems. It has a pivotal affect on the integrity of aquatic ecosystems. The physical and chemical characteristics of water have a strong influence on aquatic biota and freshwater ecosystem processes. As a result, changes in water quality may provide an early warning of environmental stress to aquatic ecosystems.

This data set includes information on water quality of lakes and streams across Ontario since 1976. It includes: * major anions and cations * nutrients * chlorophyll * metals Data were collected as part of routine monitoring of water quality of inland waters and for scientific and research purposes.

In 2002 the Alberta Geological Survey initiated a project to scan and digitize water well geophysical logs from Alberta Environment and Sustainable Resource Development (ESRD) water well data holdings. Casual and summer student staff scanned hard copy logs systematically by NTS mapsheet starting with the Cold Lake area. Scanned logs were digitized into Log ASCII Standard version 2 by Divestco Ltd. This data release consists of 8,763 LAS files, comprised mostly of resistivity logs, and a tab delimited index file.

This data set provides pesticide sample analyses results for drinking water samples for the province’s Pesticide Monitoring Program. Over 100 wells are monitored annually, with samples being collected in drinking water wells of private homes, schools, municipalities, and seniors’ housing facilities. Sampling of the wells is conducted each January/February by Departmental staff. The samples are sent to a laboratory in New Brunswick for analysis.

This web layer was developed to show areas of Nova Scotia where there is a relative high-, medium- or low-risk of uranium in bedrock water wells. The high-risk zone is defined as bedrock units where more than 15% of well water samples exceed the uranium drinking water guideline of 20 μg/L. In the medium-risk zone, between 5% and 15% of well water samples exceed the guideline and in the low-risk areas less than 5% of well water samples exceed the guideline. The risk zones were developed based on the analysis published in the open file report ‘A Uranium in Well Water Risk Map for Nova Scotia based on Observed Uranium Concentrations in Bedrock Aquifers’: https://novascotia.ca/natr/meb/data/pubs/20ofr01/ofrme2020-001.pdf

Water well records contain details of the location, construction, and groundwater level of wells drilled on Prince Edward Island.
