Surface water quality refers to the physicochemical and biological characteristics of water in rivers, lakes, reservoirs, streams, and coastal zones as they relate to ecological integrity, human use, and regulatory standards. It encompasses parameters such as nutrients (e.g., nitrogen, phosphorus), dissolved oxygen, pH, temperature, turbidity, suspended solids, salinity, trace metals, organic contaminants, pathogens, and emerging pollutants (e.g., pharmaceuticals, microplastics). Research on surface water quality involves monitoring, modeling contaminant transport and transformation, assessing pollution sources (point and nonpoint), evaluating ecosystem and human health risks, and developing management and remediation strategies within hydrological and biogeochemical frameworks.
Canada's drinking water can remain at risk long after wildfires burn out, according to a UBC-led global review that found water-quality impacts often emerge months or years later—not just immediately after a fire. Researchers ...
