Boat Harbour, Nova Scotia
Boat Harbour is a body of water on the Northumberland Strait in Pictou County, Nova Scotia. Originally a tidal estuary, construction of a pulp and paper waste effluent treatment facility in the 1960s led to the pollution of the harbour and the source of ongoing environmental concern. Treated water takes about 30 days to reach the Northumberland Strait. Since the treatment system began operation in 1967, Boat Harbour has become polluted with dioxins, furans, chloride, mercury and other toxic heavy metals. It is considered to be one of Nova Scotia's worst cases of environmental racism. In 2015, the ''Boat Harbour Act'' wrote into law that the pulp and paper mill cease effluent treatment no later than January 31, 2020; soon after this took effect, the mill closed indefinitely. The Boat Harbour Remediation Project aims to return Boat Harbour to its original state as a tidal estuary. Pilot scale testing has been completed and the project is undergoing a federal environmental assessment and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Nations In Canada
First Nations (french: Premières Nations) is a term used to identify those Indigenous Canadian peoples who are neither Inuit nor Métis. Traditionally, First Nations in Canada were peoples who lived south of the tree line, and mainly south of the Arctic Circle. There are 634 recognized First Nations governments or bands across Canada. Roughly half are located in the provinces of Ontario and British Columbia. Under Charter jurisprudence, First Nations are a "designated group," along with women, visible minorities, and people with physical or mental disabilities. First Nations are not defined as a visible minority by the criteria of Statistics Canada. North American indigenous peoples have cultures spanning thousands of years. Some of their oral traditions accurately describe historical events, such as the Cascadia earthquake of 1700 and the 18th-century Tseax Cone eruption. Written records began with the arrival of European explorers and colonists during the Age of Dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Montreal Gazette
The ''Montreal Gazette'', formerly titled ''The Gazette'', is the only English-language daily newspaper published in Montreal, Quebec, Canada. Three other daily English-language newspapers shuttered at various times during the second half of the 20th century. It is one of the French-speaking province's last two English-language dailies; the other is the ''Sherbrooke Record'', which serves the anglophone community in Sherbrooke and the Eastern Townships southeast of Montreal. Founded in 1778 by Fleury Mesplet, ''The Gazette'' is Quebec's oldest daily newspaper and Canada's oldest daily newspaper still in publication. The oldest newspaper overall is the English-language ''Quebec Chronicle-Telegraph'', which was established in 1764 and is published weekly. History Fleury Mesplet founded a French-language weekly newspaper called ''La Gazette du commerce et littéraire, pour la ville et district de Montréal'' on June 3, 1778. It was the first entirely French-language newspaper in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chloralkali Process
The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions. It is the technology used to produce chlorine and sodium hydroxide (caustic soda), which are commodity chemicals required by industry. Thirty five million tons of chlorine were prepared by this process in 1987. The chlorine and sodium hydroxide produced in this process are widely used in the chemical industry. Usually the process is conducted on a brine (an aqueous solution of NaCl), in which case sodium hydroxide (NaOH), hydrogen, and chlorine result. When using calcium chloride or potassium chloride, the products contain calcium or potassium instead of sodium. Related processes are known that use molten NaCl to give chlorine and sodium metal or condensed hydrogen chloride to give hydrogen and chlorine. The process has a high energy consumption, for example around of electricity per tonne of sodium hydroxide produced. Because the ...

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restrict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Settling Pond
A settling basin, settling pond or decant pond is an earthen or concrete structure using sedimentation to remove settleable matter and turbidity from wastewater. The basins are used to control water pollution in diverse industries such as agriculture, aquaculture, and mining. Turbidity is an optical property of water caused by scattering of light by material suspended in that water. Although turbidity often varies directly with weight or volumetric measurements of settleable matter, correlation is complicated by variations in size, shape, refractive index, and specific gravity of suspended matter. Settling ponds may be ineffective at reducing turbidity caused by small particles with specific gravity low enough to be suspended by Brownian motion. Range of applications Settling basins are used as a separation mechanism to eliminate rejected products (i.e. waste solids management strategies) of a specified size and quantity in various fields, such as aquaculture, mining, dairy, foo ...

Effluent
Effluent is wastewater from sewers or industrial outfalls that flows directly into surface waters either untreated or after being treated at a facility. The term has slightly different meanings in certain contexts, and may contain various pollutants depending on the source. Treating wastewater efficiently is challenging, but improved technology allows for enhanced removal of specific materials, increased re-use of water, and energy production from waste. Definition Effluent is defined by the United States Environmental Protection Agency (EPA) as "wastewater–treated or untreated–that flows out of a treatment plant, sewer, or industrial outfall. Generally refers to wastes discharged into surface waters". The ''Compact Oxford English Dictionary'' defines effluent as "liquid waste or sewage discharged into a river or the sea". Wastewater is not usually described as effluent while being recycled, re-used, or treated until it is released to surface water. Wastewater percolate ...

Robert L
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Scott Paper Company
The Scott Paper Company was the world's largest manufacturer and marketer of sanitary tissue products with operations in 22 countries. Its products were sold under a variety of well-known brand names, including ''Scott Tissue'', ''Cottonelle'', ''Baby Fresh'', ''Scottex'' and ''Viva''. Consolidated sales of its consumer and commercial products totalled approximately $3.6 billion in 1994. The company was acquired by the Kimberly-Clark Corporation in 1995. History Scott Paper was founded in 1879 in Philadelphia by brothers E. Irvin and Clarence Scott, and is often credited as being the first to market toilet paper sold on a ''roll''. They began marketing paper towels in 1907, and paper tissues in the 1930s. In 1927, Scott purchased a Nova Scotian pulp mill, and thus began a long series of acquisitions. It joined with The Mead Corporation in 1936 to form Brunswick Pulp & Paper Company, which used their pulp mill in Georgia to supply both Mead and Scott. The company then boug ...

Kraft Process
The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibres, the main component of paper. The kraft process involves treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na2S), known as white liquor, that breaks the bonds that link lignin, hemicellulose, and cellulose. The technology entails several steps, both mechanical and chemical. It is the dominant method for producing paper. In some situations, the process has been controversial because kraft plants can release odorous products and in some situations produce substantial liquid wastes. The process name is derived from German word ''Kraft'', meaning "strength" in this context, due to the strength of the kraft paper produced using this process. History A precursor of the Kraft process was used during the Napoleonic Wars in England. The kraft process (so called because o ...
