Groundwater is also used by farmers to irrigate crops and by industries to produce everyday goods. Most groundwater is clean, but groundwater can become polluted, or contaminated as a result of human activities or as a result of natural conditions. The many and diverse activities of humans produce innumerable waste materials and by-products ...
These reactions do not occur step by step but simultaneously. When applied to In Situ Chemical Oxidation, the collective reaction results in the degradation of contaminants in the presence of Fe 2+ as a catalyst. The overall end result of the process can be described by the following reaction: H 2 O 2 + contaminant → H 2 O + CO 2 + O 2
Groundwater treatment systems remove dissolved contaminants and sediment from the groundwater. The treatment system typically consists of a sedimentation tank and an air stripper or granular activated carbon. Groundwater is transferred from the extraction system into the treatment system where the sediment and the dissolved-phase contaminants ...
Air sparging, also known as in situ air stripping [1] and in situ volatilization is an in situ remediation technique, used for the treatment of saturated soils and groundwater contaminated by volatile organic compounds (VOCs) like petroleum hydrocarbons, [2] a widespread problem for the ground water and soil health.

Pumps being used to dewater a spillway at Baldhill Dam. Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from a location. This may be done by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.
