Habitat and ecosystem data used to conduct a baseline survey of coastal habitat in Lake Superior, Nipigon Bay, and Black Bay are included in this dataset. The Lake Superior Survey methodology consists of four general steps; 1) delineating the coastal ecosystem into coastal units based on water...

Every day, we are exposed to chemicals and pollutants in the air, water, soil, food and products we use in our home. Here are some tips on how to help protect yourself and those around you.

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. If unsafe bacterial levels are measured in water samples or if shoreline surveys identify pollution concerns, Environment and...

Habitat and ecosystem data used to conduct a baseline survey of coastal habitat in Lake Huron, Georgian Bay, and St. Marys River are included in this dataset. The Lake Huron Survey methodology consists of four general steps; 1) delineating the coastal ecosystem into coastal units based on water...

It assesses new studies and approaches and takes into consideration the availability of appropriate treatment technology in order to establish maximum acceptable concentrations that are protective of human health, measurable and achievable by both municipal and residential scale treatment...

Health Canada completed its review on the usefulness of total coliforms as part of a source-to-tap approach to producing microbiologically acceptable drinking water. This guideline technical document reviews and assesses available literature on the uses of total coliforms in drinking water...

An aesthetic objective of ≤500 mg/L has been established for total dissolved solids (TDS) in drinking water. At higher levels, excessive hardness, unpalatability, mineral deposition and corrosion may occur. At low levels, however, TDS contributes to the palatability of water.

This supporting document focuses on the health risks associated with TCE in drinking water, including multiple routes of exposure -- ingestion as well as inhalation and skin absorption from showering and bathing. It assesses all identified health risks, taking into account new studies and...

The maximum acceptable concentration (MAC) for trifluralin in drinking water is 0.045 mg/L (45 µg/L).

The maximum acceptable concentration (MAC) for trihalomethanes (THMs) in drinking water is 0.100 mg/L (100 µg/L) based on a locational running annual average of a minimum of quarterly samples taken at the point in the distribution system with the highest potential THM levels. The maximum...
