Pollution of industrial waste water caused by the discharge of harmful chemicals and substances into water, making it unsuitable for consumption and for other purposes. Although 60 to 70% of the land is covered with water, so water bodies such as lakes, ponds, rivers, reservoirs and watercourses provide us with fresh water, keep it clean, it is a matter of survival, not only for people, but also for all other life forms. Since the industrial revolution, we have achieved many things; our manufacturing process to become more efficient and productive, science has become more sophisticated, and our lives have changed. But perhaps nothing comes without a price. All the progress and development seen in past centuries have also brought with them a wide range of problems; water pollution is one of them. …show more content…
Pollution of the environment can be classified as air pollution, water pollution and noise. Water pollution means water pollution, which is unfit for consumption and for other purposes. There are essentially five main sources of water pollution from domestic wastewater, agricultural run-off and industrial wastewater, sewage from septic tanks and rainwater. There is a lack of stringent pollution control policies in many countries around the world, particularly in developing and underdeveloped
'Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives(in) it. ' (Azeem 1). In Canada, most people live in the southern part along with many agricultural and industrial activities causing the worst cases of water pollution. Water pollution is caused by population growth and industrialization, but can be prevented if proper controls are taken into consideration to help reduce the discharge of waste materials. Water pollution has been a huge disadvantaging concern for humans as well as wildlife for over many decades, but can actually be prevented if attempted. Preventing waste materials from being dumped into lakes and rivers, controlling
Water pollution is a very serious problem as it affects one of the most essential ingredients to our very livelihood. The earth is covered in water, in fact about 70% of the Earth is covered in water, only
Living in a world that is roughly 70% water, and all living creatures found on this planet depend on this resource whether directly or indirectly, making water quality an important topic and vital to sustain our world of cycles. “Determination of status of water quality of a river or any other water sources is highly indeterminate. It is necessary to have a competent model to predict the status of water quality and to advice for type of water treatment for meeting different demands.” (Bai V, 2009) With most of our water on this planet made of salt water and our constant damage towards the remaining water that can be consumed by humans is diminishing with improper distribution on a global scale. If our greed comes before companionship, and our quality of life is more important than pollution, then our future generations to come will be born into a world of chaos, and a scarce of a basic human necessity.
Both developed and developing countries face issues regarding the safety and security of water sources (Anuar, 2012; Moe, 1991). Poor water quality and quantity has been one of the main contributors to human health related illnesses in developing countries (Moe, 1991). In addition, developed countries, such as Canada have water quality issues that are highlighted through Indigenous health impairments and as a result, advocacy for cleaner water (Anuar, 2012; Rudd, 2016). In Canada, one concern imposing threats to Indigenous health is various forms of water contamination (Gracey and King, 2009).

This report will discuss large scale water pollution of the Mekong River in Vietnam. Vietnam borders Thailand, Cambodia and China and is located on the south eastern area of the Indochinese Peninsula. The Mekong River lies in Southeast Asia as indicated on the map. Mass water pollution in the Mekong River can be traced back to decades ago when Vietnam experienced a rapid economic growth during the 1960's which caused a spread and intensification of water pollution problems throughout the country. Now, although Vietnam’s water supply situation has improved over the past few decades, many rural areas, generally the poorest communities have not seen notable improvement. This report aims to raise awareness of the issue in hand and also identify and evaluate strategies to help alleviate the ongoing issue which will affect the country; environmentally, socially and economically.
Pollution is causing the destruction of environments and habits resulting in many adverse affects. The types of environments that are heavily damaged by pollution is normally freshwater ones. Polluting factors such as untreated sewage, mining waste, acid rain, fertilizers and pesticides

Water Pollution in Bhutan 1. What are the sources of water in Bhutan? 2. What activities in Bhutan cause water pollution? 3.
Pollutions such as sewage and fertilizers contain nutrients such as nitrates and phosphates. At high levels, nutrients can over stimulate the growth of aquatic plants and algae. Excessive growth of these types of organisms consequently clogs our waterways, use up dissolved oxygen as they decompose, and block light to deeper waters.[David Krantz] This could be very harmful to aquatic organisms as it affects the respiration ability of fish and other creatures of the sea. Pollution is also caused when silt and other suspended solids, such as soil, washoff plowed fields, construction and logging sites, urban areas, and eroded river banks when it rains.[David Krantz] Pollution in the form of organic material enters waterways in many different forms as sewage, as leaves and grass clippings, or as runoff from livestock feedlots and pastures. When natural bacteria and protozoan in the water break down this organic material, they begin to use up the oxygen dissolved in the water. Many types of fish and bottom-dwelling animals cannot survive when levels of dissolved oxygen drop below two to five parts per million. When this occurs, it kills a lot of aquatic organisms which leads to unbalance in our food chain. Pathogens are another type of pollution that can be very harmful. They can cause many illnesses such as minor respiratory and skin diseases. Pathogens include such organisms as bacteria, viruses, and protozoan. These pollutants enter waterways through untreated sewage, storm drains, septic tanks, runoff from farms, and particularly boats that dump sewage. Though microscopic, these pollutants have a tremendous effect evidenced by their ability to cause sickness.[David Krantz] Air is also one of the main causes of water pollution. Because, when the air is polluted it also affects the water, thus making them correlated.
Water pollution is one of the main concerns of the environment. It is known as a change in the chemical or physical condition of the waters. Polluting the waters is causing harmful and tragic diseases that affect many families. It is also a global problem that not only affects people but also animals and plants. Water pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.
Water pollution is something that can be prevented; it is important to be aware of the causes of water pollution to keep the environment safe and clean for the many generations to come. Domestic households and industrial and agricultural practices often produce wastewater that can cause rivers and lakes to become polluted. This is typically called sewage and wastewater pollution. Sewage is a term for wastewater that usually contains feces, urine, and laundry waste. With there being billions of people on earth, treating sewage is a big priority.
Pollutants are the key elements of pollution, which are generally waste materials of dissimilar forms. Pollution disturbs our ecosystem and the balance of the environment. With innovation and development in our lives pollution has reached its peaks giving rise to global warming and human illness. When raw materials, water, energy and other resources are utilized more efficiently, when fewer harmful substances are substituted for hazardous ones, and when lethal substances are eliminated from the production process. Water pollution is also a major problem in the world because almost 60% of it is fish.
Under the pollution people understand unwanted change its properties as a result of anthropogenic various substances and compounds. This contamination leads to harmful effects on the lithosphere, hydrosphere, atmosphere, biosphere, on buildings, structures and materials, and ultimately to the man himself. The main source of this pollution is the return of the great mass of waste generated in the production and consumption of human society to the nature. Especially dangerous is the entry into the environment of chemicals that were synthesized by humanity and had not previously existed in nature. There is a considerable amount of impurities and their species.
Pollution is a massive problem that the earth faces. Pollution is the action or process of making land, water, air, etc…, dirty and not safe or suitable to use. Pollution of air, water, and soil are the most complex issues. Various types of gases and toxins that are released by industries
