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.
169+ affected. 14 hospitalized. The Elk River chemical spill occurred on January 9, 2014, when crude 4-Methylcyclohexanemethanol (MCHM) was released from a Freedom Industries facility into the Elk River, a tributary of the Kanawha River, in Charleston in the U.S. state of West Virginia . The chemical spill occurred upstream from the principal ...
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]
The 90-acre (36 ha) plant was in operation from 1896 to 1996. The plant used about 1 million gallons of water per day, which was returned to the river as waste. The plant's industrial waste (primarily lead chromate and other painting, cleaning, and soldering chemicals) would be emptied directly into the river. Domestic waste would be processed ...
Hinkley groundwater contamination. From 1952 to 1966, Pacific Gas and Electric Company (PG&E) dumped about 370 million gallons (1,400 million litres) of chromium -tainted wastewater into unlined wastewater spreading ponds around the town of Hinkley, California, located in the Mojave Desert about 120 miles north-northeast of Los Angeles.

e. Nonpoint source ( NPS) pollution refers to diffuse contamination (or pollution) of water or air that does not originate from a single discrete source. This type of pollution is often the cumulative effect of small amounts of contaminants gathered from a large area. It is in contrast to point source pollution which results from a single source.
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 ...
Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are ...
