Introduction

In spite of the contribution of urbanization to the economic growth in Zhejiang, its adverse effects far much outweigh the positives since sustainability of the ecosystem and the society is at stake. Environmental concerns, particularly air pollution, are real threats to the ecosystem since they lead to increased atmospheric temperatures which in turn result in climate changes. Urbanization contributes to pollution through higher energy consumption and motorization that have resulted in higher volumes of greenhouse gasses emitted in the air. The shrinking of natural resources is another consequence of urbanization where there is the rampant destruction of natural habitats, ...

Lab 2 – Water Quality and Contamination

Abstract In this lab, the water quality, contamination, and treatment were investigated. The ability of contaminants (oil, vinegar, and laundry detergent) to remain in the water after passing through the ground was examined. Also, the simple filtering procedure was assessed for its effectivity in purifying water contaminated with soil. The quality of tap water, Fiji, and Dasani bottled waters by the content of ammonia, chlorides, iron, phosphates, total alkalinity, total chlorine, total hardness, and pH was analyzed and compared. All of the studied contaminants proved to remain in the volume of water after passing through the soil; the proposed ...

Explain Hardness of Water

Explain Hardness of Water The water that occurs in nature always contains salts, which exist in water as positive and negative ions. The salinity of fresh water is 1000 mg/L (1L of water contains 1000 mg of various salts or ions). The typical cations present in natural water are sodium, potassium, calcium and magnesium; the most common anions are chloride, sulfate, bicarbonate, nitrates, etc. Hardness of water refers to presence of calcium and magnesium ions. When water is heated, the reaction (Tebbutt, 1999):

takes place. Calcium carbonate, unlikely other salts, is insoluble and forms precipitate. The precipitate is ...

Introduction

Industries in West Virginia have violated the state-issued permit of pollution by releasing toxic substances such as coal ash and selenium into the local water supply. In addition to the threat toxic substances like coal ash and selenium pose to the health of the community, toxic water destroys the environment and destabilizes the local ecosystem of the areas impacted by such pollution. West Virginia Department of Environmental Protection (WVDEP) was formed as a guidance tool to aid persons to know when it is environmentally secure to withdraw water from the stream. This judgment is built on percentages of yearly ...

[Class title]

Summary The Autonomous Net-Zero Water Project is a water treatment project that aims to provide a sustainable water supply system. It works by gathering all waste water from a particular facility, then subjecting the water to a series of water treatment processes. After which, the water is directed back to the facility for consumption. This perpetual process of water recycling provides continuous water supply; making it possible for its users to refrain or extremely minimize tapping water from outside sources. Water recycling is not a new thing. However, the greatest challenge in making the water-recycling system sustainable ...

Introduction

The relationship between the influence of water pollution and the economy is important since without the water, no life, no prosperity and no economic development can be achieved. The scarcity of water has been identified in various parts of the world and the predictions for the future are even more concerning. Most of the planet earth is composed of water, but only 3% of it is fresh and drinkable and therefore useful for the global population. There has been seen development of the techniques of desalination, but the prices are still relatively high with various other negative factors. The ...

South of the polar Northwest Territories’ (NT) barren tundra lies the province of Alberta. The Canadian boreal forest provides expansive acres of natural habitat landscape for an array of plant and animal species. Ecologically, the Albertan forests and bogs arrest vast quantities of carbon-based pollutants, and their extensive hydrological network filters and purify millions of gallons of water. The boreal is also home to Aboriginal Communities which depend directly on the forest resources for their livelihoods (Regional Aquatics Monitoring Program [RAMP]). Nevertheless, this immaculate natural paradise is central to one of the today’s most contentious issues about the ‘ ...

Literature Review on Fracking

Introduction The extraction of natural gas has been seen the much-needed reprieve in the face of increased energy demands globally. The natural gas present unexploited energy reserves that can be used to meet the energy deficits in the countries where there are natural gas deposits. Its extraction requires the use of advanced technologies. Fracking the main technology used in the exploitation of natural gas from the rocks beneath the earth’s surface where it is trapped. The biggest proportion of the new wells for the exploitation of natural gas (90%) utilizes hydraulic fracking as the technology of choice. While ...

Abstract

In most parts of the Arab countries, the limited resources of water pose adverse constraints to both the social and economic development, while also threatening the people’s livelihood. The available surface water keeps on declining, and the ground water over-pumping that goes beyond the natural recharge rates has continued to cause great negative impact in the lowering of water table. Over-pumping of ground water also increases ground water salinity, ground water depletion, and ecological degradation (SCENR 5). The outcome prompted the Qatar government to start regulating its water resources as a measure ...

Introduction:

Corrosion refers to the partial and gradual dissolution of materials used in water treatment and supply systems, pumps, pipes, tanks and valves. In most circumstances, almost all water is corrosive and this may lead to structural failure, water leaks, capacity losses and deterioration of the microbial and chemical water quality (WHO 2011). The pipes used in water distribution are made of different materials such as plastic, metals (galvanized steel, copper, lead and iron), and even concrete. Pipes made from concrete and plastic tend to be corrosion resistant. In piping systems, however, there are several water quality factors working singly ...
