There are several types of water pollutants; one category is the microbiological, which refers to the contamination of viruses and bacteria in water. Another category is nutrient pollution, which is caused by excessive amount of nutrients in water supplies, making it undrinkable. Chemical water pollution refers to the chemical compounds that end up in water supplies. Many industries contaminate water with toxic or radioactive materials and sometimes use rivers and lakes to dispose of waste heat, resulting in thermal pollution. Water quality is threatened by many sources, besides fecal matter, water is exposed to many toxic substances.
Many factors cause water pollution to occur and increase over the years. The most important thing uses to cause water pollution is sewage pollution of boundary waters. Sewage mentions to fluid wastes containing a combination of human feces and wastewater from non-industrial human hobbies such as soaking, washing, and cleaning. In countless poor areas of the world, sewage is dumped into innate waterways, in the nonexistence of useful alternatives. Untreated sewage poses a main risk to human condition as it contains waterborne pathogens
The activity of solid waste disposal in open un-engineered landfill is the one of the factor that cause the ground water pollution due to lack of pollution control interventions such as water proof layer, leachate treatment pond, monitoring wells etc. (Mohamad et al., 2007). Groundwater pollution also occurs due to clandestine disposal of toxic wastes, especially from industrial sites, or undetected leakage from pipes, waste storage containers, or underground tanks. According to WHO organization, about 80% of all the diseases in human beings are caused by water. Once the groundwater is contaminated, its restoration to actual condition requires prolonged time and decontamination is not possible by just stopping the ingress of pollutants from the
Water pollution is the contamination of water due to unhealthy human activities. The pollution is mostly caused by industrial waste, global warming, garbage and waste dumping, and oil leakage. According to waterbenefitshealth there are many types of water pollution such as “Surface water pollution, Groundwater pollution, Microbial pollution, Oxygen Depletion pollution, Nutrient pollution, Suspended Matter pollution, and Chemical pollution.” Water pollution is a hazardous case in the world as it leads to hunger, poverty, diseases, extinction of aquatic animals, and lack of human access to fresh water.
There are several factors that causes the water pollution such as the non-point source, point source, rubbish dumping, industrial waste, and ballast water tank. Non-point source is the waste that come from many source and goes to the one point that is the water channel, the waste mostly come from the place where human population are high such as suburban development, rural home and city streets. There were also waste that come from the forestry and cropland
In concluding, there have many reasons that make water become polluted such as oil spill, plastic garbage or sewage. Water pollution also causes many problems with the living plants and animals in the water. Many countries have laws to protect the environment and limit water pollution, but that is not enough to solve the many problems. People living on this planet have to be responsible and get involved in keeping our water supply fresh and clean. Everyone needs to be more concerned with our water supply and products that can threaten it.
The major sources of water pollution in the Philippines are inadequately treated domestic wastewater or sewage, agricultural wastewater, industrial wastewater, and nonpoint sources such as rain- and groundwater runoff from solid waste or garbage deposits, which is also known as leachate. (The Problem) Water pollution in the Philippines can cause waterborne diseases by drinking polluted water: Typhoid, Amoebiasis, Giardiasis, Ascariasis, and Hookworm. Water pollution may also result from interactions between water and contaminated soil, as well as from deposition of air contaminants (such as acid rain) (Pollution Effects On Humans, Animals, Plants and The Environment) The World Bank estimates that exposure to water pollution and poor sanitation account for one-sixth of reported disease cases, and nearly 6,000 premature deaths per year. The cost of treatment and lost income from illness and death due to water pollution is pegged at PHP 6.7 billion (US$134 million) per year (PEM 2006). (Lohani, B. N., and T. M. Roblo) (Lohani, B. N., and T. M. Roblo) The area in the Philippines that are affected by water pollution are: According to data from the Philippine Environment Monitor and the EMB, four regions had unsatisfactory ratings for their water quality criteria.
Water pollution can be explained in many ways. In real term pollution meaning is that more than one substances have built up in such an extent in water that they all cause the serious problems for all living things. Lakes, rivers and oceans can desolve a certain amount of pollution by spreading it harmlessly. If you poured a glass of ink into a lake then ink will quickly vanish due to much volume of lake 's clean water but if you poured a gallon of ink into lake then the colour of lake will be changed in seconds. In return it will affect the lake water and also the health of all those who depend on the lake.
But, many of these measures are not implemented properly or are not inspected by the concerned authorities. 8. CONCLUSIONS AND SUGGESTIONS After the detailed study and analysis of all the laws and regulations pertaining to control the water pollution, and reading about various enforcement agencies like National Green Tribunal, Central pollution control board and State pollution control board etc. and their roles in curbing the menace of water pollution, we come to the conclusion that though we have laws and regulations to curb pollution but these laws are not stringently followed. As a result, our rivers are in a really pitiable state.
WATER POLLUTION IN ELURU CANAL – VIJAYAWADA Introduction: Water pollution is referred to the contamination of water bodies such as lakes, ponds, canals, rivers, oceans and ground water etc by physical and chemical substances. This occurs when pollutants are directly or indirectly discharged into the water. It leads to environmental degradation effecting the plants and organisms living in the water bodies. Water pollution may also occur from natural causes such as sedimentation, volcanoes, storms, floods, earthquakes etc. Though earth is covered by 70% of water, hardly 2% is the drinkable water.
