Conflicts among various users of water are increasingly over issues involving water quality as well as water quantity. Natural water bodies are able to serve many uses, including the transport and assimilation of waterborne wastes. But as natural water bodies assimilate these wastes, their quality changes particularly it degrades. If the quality drops to the extent that other beneficial uses are adversely affected, the assimilative capacities of those water bodies have been exceeded with respect to those affected uses. Water quality management measures are actions taken to ensure that the total pollutant loads discharged into receiving water bodies do not exceed the ability of those water bodies to assimilate those loads while maintaining the levels of quality specified by quality standards set for those
Within heavily populated cities, such as those in China, even the smallest of activities could lead to hugely negative effects for the local water bodies. Even with relatively low ecological footprints per capita, the shear volume of citizens could offset that and result in poor environmental outlooks. This is because a large population calls for increases to industry and agriculture, which contribute to water pollution individually (Shao et al., 2006). Industrialization introduces so many chemicals into the waters, and the fertilizer and pesticides used in industrial farming also greatly pollutes water. Such activities have created a reality where toxicants are now mainly absorbed directly from food because of the heavy contamination of water sources, such as lakes and fresh water bodies.
The water we drink is an essential ingredient for our wellbeing and a healthy life. Unfortunately polluted water and air are common throughout the world. Polluted water consists of sewage water and industrial discharged heavy metal effluents which cause damage to human health or the environment. Let me tell explain about the causes of water pollution. First of all, the first cause of water pollution is sewage water.
Ultimately, climate change is likely to have a negative impact on countries and make them increasingly difficult to meet urban and agricultural water needs. Among the challenges ahead, measures are already being taken for the mitigation of climate change with water supply and disposal. The recycling of wastewater can promote employment within irrigation systems. Treated wastewater and also surface runoffs can be deliberately percolated (groundwater replenishment) and then used again later. Flooding events can be mitigated through dykes or mobile flood protection systems.
(Moloi, 2013). Damming of rivers on the other hand has a high impact on the quality of the water. If a plant will be isolated into the water for a long time, this may cause the inclination of phosphates and other dissolved nutrients in the water or simply, eutrophication. (Moloi, 2013). It has been said that water pollution starts to transpire when unwanted flow of liquid wastes spreads over the water source, which later on causes the change of the water quality.
Possible environmental impact If river pollution continues it may lead to the increase of pathogens in the river channel and further biodiversity loss. Sewage systems often flow into rivers in Ireland, this sewage may contain many pathogens. If sewage treatment and management is not controlled, these pathogens may end up in people’s drinking water, bathing water etc. Poor sanitation is a major problem in developing countries such as India where cholera and dysentery are killing millions. If these pathogenic rivers flood, it may destroy farmland and cause it to become baron 6.
In addition to that waste water discharge from industries and urban areas also can bring large amounts of suspended particles to the water. Specially untreated effluent discharge illegally to the natural water causes can bring significant loads of suspended material. In addition to that the presence of bottom disturbing fish species such as large number of bottom feeders, which stir the bottom sediments can also contribute to higher turbidity. In addition to that excessive algal growthaln contribute to higher turbidity value. Turbidity may have direct and indirect impact on physical water properties and aquatic life.
The industrial wastes bring many disadvantages and bad consequences in terms of environmental damage and also finance. Industrial wastes can contaminate the environment, pollute rivers and water ways, and also damage the balance of ecosystems. With that being so, wastes produced by industries need to be treated so that they may be harmless or at least, less harmful. This, in turn, provides a cost for the government to pay. The growing trend for the industrial waste is that in terms of the amount, it is expected
India is the largest producer of milk in the world and it is also largest consumer of milk consuming almost its whole milk production. Dairy industry in India has shaped lives of millions of dairy farmers. Dairy sector in India has been a significant contributor to the Gross Domestic Product and its value of output has grown significantly. Dairy sector is one of the important contributors in the growth of Indian economy. The Indian dairy industry is mainly constituted of 22 state milk federations, 110,000 dairy cooperative societies involving more than 12 million milk producers.
