Freshwater environmental quality parameters are those chemical, physical and biological parameters that can be used to characterise a freshwater body. Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations.
In 1968, the Province of Ontario and the Government of Canada set aside an area in a sparsely inhabited region of central Canada, southeast of Kenora, Ontario, which is relatively unaffected by external human influences and industrial activities, for experimental studies of the causes and control of eutrophication and other types of water pollution.
Water research during the late 1970s and 1980s indicated that stormwater runoff was a significant cause of water quality impairment in many parts of the US. [25] Research on stormwater pollution continues in the 21st century, with findings that urban runoff is an ongoing source of water quality problems nationwide.
Since the release of the initial 1989 study, titled A study of interior landscape plants for indoor air pollution abatement: An Interim Report, [6] further research has been done including a 1993 paper [7] and 1996 book [8] by B. C. Wolverton, the primary researcher on the original NASA study, that listed additional plants and focused on the removal of specific chemicals.
A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
Paustenbach was at the center of a publishing scandal [12] involving the research of Chinese scientist Jian Dong Zhang, who published a paper in 1987 reporting an association between chromium pollution of drinking water and higher rates of stomach cancer in residents of three villages in Liaoning Province (in rural northeastern China) who lived ...
The [[World Water Monitoring [36] Day|EarthEcho Water Challenge]] is an international education and outreach program that generates public awareness and involvement in safeguarding water resources globally by engaging citizens to conduct water testing of local water bodies. Participants learn how to conduct simple water quality tests, analyze ...
Brine treatment is commonly encountered when treating cooling tower blowdown, produced water from steam-assisted gravity drainage (SAGD), produced water from natural gas extraction such as coal seam gas, frac flowback water, acid mine or acid rock drainage, reverse osmosis reject, chlor-alkali wastewater, pulp and paper mill effluent, and waste ...
