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.
Analysis of groundwater contamination may focus on soil characteristics and site geology, hydrogeology, hydrology, and the nature of the contaminants. Causes of groundwater pollution include: naturally-occurring (geogenic), on-site sanitation systems, sewage, fertilizers and pesticide, commercial and industrial leaks, hydraulic fracturing, and ...
English: Diagram showing the transport of oil to groundwater following a spill. Oil spills in or on soils have the potential to release benzene to the environment when a precipitation event carries dissolved benzene to groundwater sources.
Climate-driven extreme weather conditions, such as droughts and intense precipitation, may be accelerating the pace at which toxic nitrates are polluting groundwater, a recent study has found.
Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta , causing serious arsenic poisoning to large numbers of people.
Groundwater has been pumped in the valley since 1850, when residents began to build pumps to help make up for the lack of surface water in the area. [2] At the turn of the 20th century, California became as a leading agricultural producer due to its technological advances in land management , irrigation and machinery.
Toluene is an organic compound which is mostly harmless to adults and is sometimes abused as an inhalant. Fetal toluene syndrome has been defined and resembles fetal alcohol syndrome with resultant birth defects, but the U.S. Centers for Disease Control and Prevention have identified differentiating features between the two syndromes including FTS having the additional facial features of ...
The Newmark Groundwater Contamination Site resides on part of a groundwater aquifer that supplies water to the cities of San Bernardino, Colton, Loma Linda, Fontana, Rialto, and Riverside. Many of the wells responsible for supplying water to these areas lay down gradient from the two contamination plumes that resulted from the pollution. [1]
