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
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.
Like ISCO, it is able to decontaminate many compounds, and, in theory, ISCR could be more effective in ground water remediation than ISCO. Chemical reduction is one half of a redox reaction, which results in the gain of electrons. One of the reactants in the reaction becomes oxidized, or loses electrons, while the other reactant becomes reduced ...
In 1987, he founded the University Consortium for Field-Focused Groundwater Research which consists of 26 principal investigators and 12 core corporate sponsors. [5] Currently comprising 16 universities, it gives graduate students the chance to conduct research on contaminated industrial sites, much as John Cherry had done himself before.
Electro Thermal Dynamic Stripping Process (ET-DSP) is a patented in situ thermal environmental remediation technology, created by McMillan-McGee Corporation, for cleaning contaminated sites. ET-DSP uses readily available three phase electric power to heat the subsurface with electrodes .
The best results have been obtained with the following treatment scheme, consisting of a series of different steps: [14] [15] Phase 1: Pumping of contaminated water: the injection of the leaching solution is stopped and the contaminated liquid is pumped from the leaching zone. Subsequently, clean groundwater flows in from outside of the ...
Where groundwater recharge is practised (a process in which river water is injected into an aquifer to store the water in times of plenty so that it is available in times of drought), the groundwater may require additional treatment depending on applicable state and federal regulations.
