Water Pollution In New Zealand
Water pollution in New Zealand is an increasing concern for those who use and care for waterways and for New Zealand regulatory bodies. An increase in population is linked to an increase in water pollution, due to a range of causes such as rural land use, industrial use and urban development. Fresh water quality is under pressure from agriculture, hydropower, urban development, pest invasions and climate change. While pollution from point sources has been reduced, diffuse pollution such as nutrients, pathogens and sediments development and from stormwater in towns is not under control. There are more than 800 water quality monitoring sites around New Zealand that are regularly sampled. , Auckland is the region with New Zealand's most polluted waterways, with 62% of rivers and lakes graded poor by the Ministry for the Environment for swimming, and 0% of rivers and lakes graded as good. In 2018, waterways across New Zealand have been showing improvements across a number of water q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Pollution Sign On The Waimakariri River
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water covers ab ...

Surface Water Drain In Rotorua
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several non equivalent such formalizations, that are all called ''surface'', sometimes with some qualifier, such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstraction are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfac ...

Resource Consent
A resource consent is the authorisation given to certain activities or uses of natural and physical resources required under the New Zealand Resource Management Act (the "RMA"). Some activities may either be specifically authorised by the RMA or be permitted activities authorised by rules in plans. Any activities that are not permitted by the RMA, or by a rule in a plan, require a resource consent before they are carried out. Definition and nature The term "resource consent" is defined as; * a permit to carry out an activity that would otherwise contravene a rule in a city or district plan. * a permission required for an activity that might affect the environment, and that isn't allowed 'as of right' in the district or regional plan. A resource consent, once granted to an applicant, is neither real nor personal property. Therefore, resource consents cannot be 'owned'; they are 'held' by 'consent holders'. Types A resource consent means any of the following: * land use consent ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanitary Sewer
A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater) to a sewage treatment plant or disposal. Sanitary sewers are a type of gravity sewer and are part of an overall system called a "sewage system" or sewerage. Sanitary sewers serving industrial areas may also carry industrial wastewater. In municipalities served by sanitary sewers, separate storm drains may convey surface runoff directly to surface waters. An advantage of sanitary sewer systems is that they avoid combined sewer overflows. Sanitary sewers are typically much smaller in diameter than combined sewers which also transport urban runoff. Backups of raw sewage can occur if excessive stormwater inflow or groundwater infiltration occurs due to leaking joints, defective pipes etc. in aging infrastructure. Purpose Sewage treatment is less effective when sanitary waste is diluted with stormwater, and combined sewer overflows occur when r ...

Freedom Camping
Camping is a popular activity for both New Zealand residents and for some of the two million foreign tourists arriving every year. Campsites of different standards, generally in conjunction with other forms of accommodation, are offered by holiday park operators throughout New Zealand. The facilities at these campsites vary from just a basic toilet to a full range of camp ground amenities. Popular campsites during the summer holidays include the Mavora Lakes, Kaiteriteri Beach, Mārahau and the Coromandel Peninsula. The summer holiday period, which is over Christmas and New Year, coincides with the peak of inbound tourists, leading to high levels of crowding at popular locations. Oversight The Department of Conservation, which administers one third of the land area of New Zealand, operates 250 vehicle-accessible campsites on public land. The largest organisation representing motorised campers is the New Zealand Motor Caravan Association, which was founded in 1956. Camping ...

Backcountry Hut
A wilderness hut, bothy, backcountry hut, or backcountry shelter is a free, primitive mountain hut for temporary accommodation, usually located in wilderness areas, national parks and along backpacking (wilderness), backpacking and hiking routes. They are found in many parts of the world, such as Finland, Sweden, Norway, northern Russia, the Alps, the Pyrenees, Scotland, Australia, New Zealand, Canada, and the United States. Huts are basic and unmanned, without running water. Bothy A bothy is a basic shelter, usually left unlocked and available for anyone to use free of charge. They are found in remote mountainous areas of Scotland, Northern England, Northern Ireland, Wales and the Isle of Man. Most are ruined buildings which have been restored to a basic standard, providing a windproof and watertight shelter. They vary in size from little more than a large box up to two-storey cottages. They usually have designated sleeping areas, which commonly are either an upstairs room or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fecal Matter
Feces ( or faeces), known colloquially and in slang as poo and poop, are the solid or semi-solid remains of food that was not digested in the small intestine, and has been broken down by bacteria in the large intestine. Feces contain a relatively small amount of metabolic waste products such as bacterially altered bilirubin, and dead epithelial cells from the lining of the gut. Feces are discharged through the anus or cloaca during defecation. Feces can be used as fertilizer or soil conditioner in agriculture. They can also be burned as fuel or dried and used for construction. Some medicinal uses have been found. In the case of human feces, fecal transplants or fecal bacteriotherapy are in use. Urine and feces together are called excreta. Skatole is the principal compound responsible for the unpleasant smell of feces. Characteristics The distinctive odor of feces is due to skatole, and thiols ( sulfur-containing compounds), as well as amines and carboxylic acid ...

Anaerobic Digestion
Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. The process is used for industrial or domestic purposes to manage waste or to produce fuels. Much of the fermentation used industrially to produce food and drink products, as well as home fermentation, uses anaerobic digestion. Anaerobic digestion occurs naturally in some soils and in lake and oceanic basin sediments, where it is usually referred to as "anaerobic activity". This is the source of marsh gas methane as discovered by Alessandro Volta in 1776. The digestion process begins with bacterial hydrolysis of the input materials. Insoluble organic polymers, such as carbohydrates, are broken down to soluble derivatives that become available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide, hydrogen, ammonia, and organic acids. In acetogenesis, bacteria convert these resulting organic aci ...

Human Waste
Human waste (or human excreta) refers to the waste products of the human digestive system, menses, and human metabolism including urine and faeces. As part of a sanitation system that is in place, human waste is collected, transported, treated and disposed of or reused by one method or another, depending on the type of toilet being used, ability by the users to pay for services and other factors. Faecal sludge management is used to deal with fecal matter collected in on-site sanitation systems such as pit latrines and septic tanks. The sanitation systems in place differ vastly around the world, with many people in developing countries having to resort to open defecation where human waste is deposited in the environment, for lack of other options. Improvements in "water, sanitation and hygiene" (WASH) around the world is a key public health issue within international development and is the focus of Sustainable Development Goal 6. People in developed countries tend to use flu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarawera River
The Tarawera River is in the Bay of Plenty Region in the North Island of New Zealand. It flows from Lake Tarawera, northeastwards across the northern flanks of the active volcano Mount Tarawera, and past the town of Kawerau before turning north, reaching the Bay of Plenty west of Edgecumbe. The Tarawera Falls on the river are considered to be quite spectacular. Environmental issues The Tasman Pulp and Paper Mill, now owned by Norske Skog, has been discharging waste into the river since 1955. Local residents have erected signposts labelling the river as the "Black Drain" since the 1990s. The dark colour is due to the presence of pollution from farms, sewage and stormwater but it is predominantly from pulp and paper mill effluent. As of 1997, pulp and paper mills were discharging over 160 million litres of industrial waste into the river per day. By 2006, the oxygen levels in the river had reached a level where fish could survive, however the water colour was still dark. Since ...

Norske Skog
Norske Skog ASA, formerly Norske Skogindustrier ASA, which translates as ''Norwegian Forest Industries'', is a Norwegian pulp and paper company established in 1962. The company has long been one of the world's leading manufacturers of newsprint and magazine paper. Due to a declining market for publication paper, the company has increasingly focused on other uses of timber and recycled paper, such as packaging. The company is headquartered in Norway and has factories in five countries and an annual production of approximately 2 million tonnes of paper (2020). History Norske Skog started in 1962 with the construction of a paper mill at Skogn in Norway, with the plant opening in 1966 and a second paper machine added in 1967. Half the capital for the project was issued by the Norwegian Forest Owners Association. In 1972 Norske Skog started a cooperation with Follum Fabrikker in Hønefoss. By 1989 Norske Skog had acquired Follum Fabrikker and Union in Skien as well as Saugbrugsfore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tasman Mill
The Tasman Mill site is a pulp and paper mill located on Fletcher Avenue just outside the town of Kawerau in New Zealand. The Tasman Mill site is the largest single employer in the Eastern Bay of Plenty region. Three pulp or paper companies previously operated in Kawerau: Norske Skog operated the mechanical pulp mill and newsprint paper mill; Oji Fibre Solutions, formerly Carter Holt Harvey, operated the kraft pulp mill; and SCA (now Essity) who manufacture tissue and base paper (physically separate mill on Fletcher Avenue). The Tasman Pulp and Paper Mill has been a source of controversy due to the discharging of waste into the Tarawera River. Despite protests from locals (including local Iwi), resource consent was renewed in 2009 to allow for discharge into the river for the next 25 years. The workforce at the Tasman Mill declined from its peak in the 1980s. The Norske Skog Tasman mill that produced newsprint was closed in June 2021, with the loss of 160 jobs. The main produc ...
