The disease was gradually traced back to well-water supplies contaminated with human waste from cesspools and privy vaults. As a result of this development, water closets in larger towns were to a larger extent connected to storm sewers. On the other hand, the handling of one problem led to the introduction of another one: surface water pollution. A receiving water body will up to a certain level be able to render harmless the contaminants of discharged wastewater through dilution. Nevertheless, when the quantities of pollutants exceed the recipients critical level, they will possibly do harm to the surroundings.
Wastewater is often classified as industrial or domestic wastewater. In waste water, it contains a lot of harmful pollutants liked: lead, manganese, cadmium, zinc and so on. As known, these pollutants are very dangerous when humans or other species consumed or even when exposed to it. These will affect human health and kill aquatic organisms. Many serious health effects including mutations, cancer, organ damage and death are caused by violet dye in large quantities.
Even though they are treated, they are never the same fresh water. In many situations, the sewage is not treated but directly dumped into the sea or water bodies. This is very dangerous because they pollute the environment and water bodies and bring many deadly diseases to us. Septic Tanks - Biological processes break down the solids from septic tank and when the liquid is drained to the water it is making huge troubles. The e-coli bacteria which is present in human waste is very dangerous and drinking this water can cause harmful side effects .
Some of the Effects that Waste accumulation can have on the environment include Surface water Contamination, Soil Contamination and pollution. Waste accumulation is also a cause of health concern in our Communities today, the release of toxic and hazardous waste has produced drastic effects on the human health. Most of the
As the populations in the country grow, the water pollutions tend to become worse. This is because the sewage wastes when discharged in water are mostly produced from human activity and hence act as the biggest pollutant of fresh water.  The discharge of untreated sewage into a river can cause harmful to human health and also immediately reduce the amount of dissolved oxygen in the water. Consequently, yields to horrible smell to the river and harm the other living
Eutrophication makes water resources unsafe for use as certain algal blooms, fertilizers or pesticides contain harmful chemicals that is not safe for usage. Lake Loktak is thickly populated with areas surrounded by cultivated lands. (Rashmi Rekha Patra, 2012) The fertilizers and sewage being washed or improperly disposed into the Lake are the main causes of eutrophication. The effects of eutrophication on water resources are vast. The water becomes unusable for recreational, consumption or agricultural purposes.
Water surrounds all marine organisms, composes the greater bulk of their bodies, and is the medium in which various chemical reactions take place, both inside and outside of their cells. Survival also requires energy input to drive these chemical reactions and environmental conditions suitable to maximize the efficiency of these reactions. Water pollution is one of the most serious environmental problems. Pollution causes unfavorable alteration of environment that poses threat ultimately to the survival. Pollutants can be natural or anthropogenic, but even when it is natural, its adverse effect may be primarily due to human contributions and exposure in
Industrial corporations have continuously used bodies of water to their advantage by having their factories use water as an energy source and trash bin. Toxic chemicals are released by these factories and sometimes directly dumped back into the water. Aquatic plants benefit from the carbon dioxide released by factories, but too much can harm the biodiversity of that ecosystem and other marine life and acidity levels will also rise. A bigger population means more consumption and as the human consumption has increased throughout the years, landfills have been overflowed by large amounts of trash. When liquids and other materials begin to degrade, they release a juice that can be toxic if consumed.
Apart from that, the industrial development also contribute with the increase of water pollution all over the world. water is a very special and unique substances, because it can naturally cleanse and renew itself. it cleanse and renew itself by allow the pollutants to diluting or break down or settle out to the point that there are no harmful concentration but the natural process usually take a lot of time to make sure the water is free from the pollutions. At the same time it difficult to make sure the water is free from the pollutions because of the excessive quantities of harmful contaminant are added to the water [safe drinking water foundation, n.d.]. That the reason why the water purification process have been created.
SURFACE WATER POLLUTION: FACTORS AND IMPLICATIONS Surface water includes water bodies on the earth 's crust such as well, river, lake, pond, stream, ocean. The water we use for our daily purposes and supplied by the municipalities mostly includes surface water primarily from river catchments. Water for agriculture is taken from rivers; it used to be taken from wells also but now it has shifted to bore wells mostly. Pollution refers to the presence of foreign matter in the resource which degrades the quality of the resource and may cause harm to the consumers. Surface water pollution occurs in many ways.
