Water is a necessity for all life on Earth, yet it is one of the most threatened vital resources in the world. “Water pollution is any contamination of water with chemicals or other foreign substances” (Water Pollution). From automobile fluids that seep into sewage systems to household products that are usually poured down sinks, all these items can contribute to the destruction of the environment. However, these items have a common denominator: humans. Not enough people are aware of the dangerous effects that water pollution has towards the environment and what causes it.
Now a day’s water pollution is a major and most important problem due to discharge of untreated industrial effluents into nearby water bodies [36, 37]. Water pollution problem is present in both developing and developed countries. Human activities are major contributors to water pollution. The polluting substances include pathogenic organisms, plant nutrients that stimulate algal blooms, inorganic and organic toxic substances . Water used in every industry and effluent is disposed to the environment leading to the surface and ground water pollution .
These impurities must be removed before the water can be used safely for drinking, cooking, washing, or laundering.Some industries must clean polluted water before using it in manufacturing processes." This means polluted water makes things less safe to use and consume.This means the water could contaminate the meat which could position humans. She also says “Water polluted with human and animal wastes can spread many diseases, including typhoid fever, cholera, and dysentery. " This statement means that polluted water can spread a varying number of diseases. If the meat can cause diseases, this could potentially increase a risk of death and illness for the consumers.The meat production claim is invalid because if they did pollute the animals water it could increase a disease, poison, and death risk in the consumers which could lead to legal action from the former consumers or their
Atmospheric pollution is caused by pollutants such as smoke from factories entering the atmosphere and being carried to waterways. Industrial waste can also create polluted runoff that collects in rivers and lakes. Another reason for water pollution is chemically treated sewage. This water carries harmful chemicals and high amounts of bacteria, which can potentially lead to serious diseases. Runoff from fields can contain chemical fertilizers and pesticides which can pollute
Also, by factories leaking toxic in the water secretly. This two is the major reason why water pollution happens. Except for this two reasons, there are a lot of other reason why it happens. The effect of the water pollution is very dangerous to everyone in the world, and every living organism. In the first paragraph, I will explain the meaning of water pollution and the cause of water
Over 780 million people are without access to clean drinking water, and around 2.5 billion people do not have access to an adequate sanitation facility (Bradford). There are two primary ways in which water pollution is caused. The first way consists of objects such as trash from a landfill or parts of a boat which have fallen into the water. The other cause is due to fertilizers and other chemicals being spilled into the water ("Pollution"). Once enough pollutants fill the water, it becomes likely for it to become contaminated with dangerous pathogens, which survive on the pollutants and can be dangerous to the wildlife.
The drainagewater contains heavy metals in addition to biological contaminations so care has to be taken to avoid this water. Land/ Solid waste Pollution- the main cause of environmental pollution is improper management of solid waste. The causes of Land pollution are: waste disposal, mining, urbanization, agriculture chemical, atmospheric deposition, soil erosion. The adverse effect of pollution is global warming-refers to the general increase in the earth’s average temperature, which causes changes in climate patterns across the globe. The earth’s average temperature has been increasing over the last century.
Water is regarded as polluted if certain substances or conditions are present to such a point that water cannot be used for specific purposes. Water is defined as the presence of excessive amounts of pollutants in water in such a way that water is no longer suitable for drinking, bathing, cooking and any other uses. Pollution is said to be the introduction of contamination into the environment. Pollution is created by industrial waste, commercial waste, agricultural activities and human activities such as transportation (Owa, 2013). Sources of water pollution According to (Owa, 2013), water pollution arises from various activities such as sewage, leakages, high population density, oil spilled, industrial waste dumped into waters, flooding
2. Reasons and Problems related to Wastewater Quality of water is a serious issue across the world and uncontrolled disposal of municipal, industrial and agricultural liquid, solid, and gaseous wastes poses serious threats to the sustainability. This has led to the contamination of air, water and soil along with its contribution to global warming. There are several factors which are responsible for continuous degradation of water quality like increasing population, industrialization and urbanization. As the demand of potable water is increasing, the need of treatment and safe disposal of wastewater is becoming essential to safeguard public health and reduce unbearable levels of environmental deterioration.
For example, drinking water need to be in the highest quality , un like agricultural and industrial needs. That means polluted water is a level of very low water quality, which can not be used for drinking. Unfortunately, some countries have no enough fresh water, so they have no other choices to drinking polluted water. Thus, people in those countries got illness from the water they drink. 1.2.
