Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. [ 1]: 6 It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies.
Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and industry, although laws and regulations introduced in the late 20th century have improved water quality in many water bodies. [ 1] Extensive industrialization and rapid urban growth ...
The objectives were effective abatement of pollution, conservation, and rejuvenation of the Ganges. Under the project, 8 states are covered. Ministry of Drinking Water Supply and Sanitation proposed to make 1,674 gram panchayats by the Ganges open defecation-free, at a cost of ₹ 1,700 cr (central share).
A 2017 study found that 83% of tap water samples taken around the world contained plastic pollutants. [96] [97] This was the first study to focus on global drinking water pollution with plastics, [98] and showed that with a contamination rate of 94%, tap water in the United States was the most polluted, followed by Lebanon and India.
Marine pollution made further international headlines after the 1967 crash of the oil tanker Torrey Canyon, and after the 1969 Santa Barbara oil spill off the coast of California. [citation needed] Marine pollution was a major area of discussion during the 1972 United Nations Conference on the Human Environment, held in Stockholm.
Thermal pollution is the rise or drop in the temperature of a natural body of water caused by human influence. Thermal pollution, unlike chemical pollution, results in a change in the physical properties of water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. [ 1]
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
Water conservation aims to sustainably manage the natural resource of fresh water, protect the hydrosphere, and meet current and future human demand. Water conservation makes it possible to avoid water scarcity. It covers all the policies, strategies and activities to reach these aims. Population, household size and growth and affluence all ...
