Pollution (or contamination) can also occur from naturally occurring contaminants, such as arsenic or fluoride. [ 1 ] Using polluted groundwater causes hazards to public health through poisoning or the spread of disease (water-borne diseases). The pollutant often produces a contaminant plume within an aquifer.
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 ...
Groundwater remediation is the process that is used to treat polluted groundwater by removing the pollutants or converting them into harmless products. Groundwater is water present below the ground surface that saturates the pore space in the subsurface. Globally, between 25 per cent and 40 per cent of the world's drinking water is drawn from ...
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 ...
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.
3M contamination of Minnesota groundwater. From the 1950s through the early 2000s, 3M disposed of per- and polyfluoroalkyl substances produced during the manufacturing process of various industrial products in four dumping sites in Minnesota. [1] These chemicals have contaminated the groundwater of over 170,000 residents of the Twin Cities East ...
The wells will allow the electric utility and the state agency to determine the "extent of petroleum hydrocarbon groundwater contamination" from a decades-old plume of diesel fuel at the site of a ...
