Water pollution

Mexico that is noted for oxygen depletion is called the “dead zone”. A dead zone, also known as a hypoxia zone, is an area with little to no dissolved oxygen in the water. It is believed that these areas are depleted of oxygen because of the pollution in the runoff delivered by the mighty Mississippi River. A fair amount of this pollution comes from fertilizer runoff from Midwestern farms that leach into…

The Ganges River runs over 1500 miles long through India: rising in the Himalayas, and falling in Bangladesh. For the majority of this area, the river is not only a source of water, but it also is mother to the millions of Hindus in India who believe that she is pure and holy. The Ganges river is also subject to have hundreds of carcasses of animals, bodies of humans, and gallons of waste thrown into it on a daily basis. Unfortunately, the cleaning of the Ganges is not an easy process as there…

Eutrophication, a form of water pollution, threatens freshwater ecosystems and is the cause of many frightening deteriorations within freshwater environments. An influence on eutrophication is nutrient loading. To be able to examine the relationship between nutrient loading and eutrophication, one must: understand the basis of nutrient loading, the human contribution to nutrient loading, the problems nutrient loading poses to freshwater ecosystems, and the process of nutrient loading management.…

Water Shortage: Waterborne Diseases The aspect of water security I choose to focus on is water pollution, specifically waterborne diseases. Waterborne diseases such as polio, cholera, hepatitis, and dysentery are awful diseases and considerably debilitating and in some cases fatal. These diseases are caused by highly pathogenic waterborne bacteria such as Clostridium botulinum, Vibrio cholerae, Shigella dysenteriae, and Salmonella typhi. The World Health Organization attributes the mortality…

dropped 10mm by 3:00 when it was refilled and left overnight to soak. On the 23/2/16 we resumed work at 9:00 and it was clear that the water had not fully soaked away with 100mm water still present at the bottom. Mud had to be removed from the bottom of the hole before we proceeded to the percolation test. The hole was filled to 400mm at 9:23. From our observations the water level was very slow dropping down throughout the day. After the first hour the level had only dropped by 22mm. The level…

Wastewater can be formed from domestic, industrial, agricultural, commercial activities or any combination of these. Rainwater runoff is also considered as wastewater. This wastewater is full of chemicals, bacterial, viruses and other contaminants regardless where it comes from. Based on this reason, wastewater treatment is needed and crucial for converting the wastewater into an effluent that can be either discharged to the environment or reused. However, wastewater treatment plant posed safety…

The city of Mumbai, situated off the Western coast of India, has relied on the sea to facilitate trade and transportation, promote tourism, and provide a food source. However, as sea levels continue to rise, the intrusion of water will cause detrimental effects on the economy and social fabric of this city. Mumbai has served as a hub for maritime trade since 1000 BCE when the city was heavily involved in seaborne commerce with Egypt and Persia (Raghavan). As India’s financial and commercial…

found out that for most of our measured variables, the stream water quality diminished the further we got away from the source (the mountain). Water quality is defined in terms of the chemical, physical and biological content of water. There are multiple measures that constitute good water quality which is why we measured 7 different variables. The results we got for Aquatic macroinvertebrates index is vital evidence that the water quality decreased. We found only one 2 at site 1, ten 2’s at…

According to research, most breweries have similar equipment to brew its products meaning there may not be too much of a difference between Anheuser-Busch and its competitors (Appleyard). To constantly reduce water usage, Anheuser-Busch needs to be in the front-lines of innovation. As newer technologies are developed, Anheuser-Busch will need to take advantage of the opportunities and implement the newest technologies in its breweries. Bioelectric Wastewater Management also known as EcoVolt is…

Gilbane Gold, David Jackson, the engineer responsible for waste treatment in Z-Corp, was put in a very difficult situation. In the beginning, David was getting results from Frank’s waste water discharge tanks that showed that they have been releasing arsenic and lead at higher levels than what the city allows. The waste water ends up into the popular and profitable sludge product called Gilbane Gold. Gilbane Gold is sold as a fertilizer to farmers for about 75 years. David mentions his concern…
