In recent decades, the pollution of groundwater has emerged as a major environmental issue. The infiltration of harmful substances into the subsurface through industrial, commercial, and residential activities has led to the contamination of water with toxic chemicals. As analytical techniques have advanced, even low levels of contaminants have been found to pose a risk, leading to a growing awareness of the scope of this problem.

Groundwater contamination has become a significant environmental issue in recent years. To address this problem, ozone groundwater remediation and ozone-based advanced oxidation techniques have been effectively employed to eliminate harmful substances from groundwater. These oxidation systems have been utilized in both:

• The process of In-Situ Chemical Oxidation (ISCO) involves the injection of ozone and/or other agents into the ground where oxidation reactions occur.
• Pump and Treat Chemical Oxidation involves pumping the contaminated groundwater out of the ground and treating it on the surface using ozone and/or other chemicals. Depending on the situation, the treated water may either be reinjected into the ground or discharged on the surface.

It is crucial to acknowledge that In-Situ Chemical Oxidation (ISCO) encounters a complex underground environment, including both anthropogenic and naturally occurring compounds, varying compound phases, diverse rock/soil nature, and more. Therefore, the effective application of ISCO requires determining not only the appropriate chemicals but also the correct injection method. On the other hand, Ozongenerators offer a simpler treatment environment, as it is limited to the water extracted from the well.

Alternative chemical oxidation methods exist for both In-Situ Chemical Oxidation (ISCO) and Pump and Treat applications, such as permanganate, hydrogen peroxide, Fenton’s Reagent (catalyzed by iron-based hydrogen peroxide), and persulfate. In Pump and Treat applications, UV treatment may be employed either alone or in combination with ozone, peroxide, or ozone and peroxide.

Ozone groundwater remediation and ozone-based advanced oxidation processes’ reactivity with different compounds present in groundwater can be observed through the ozone-groundwater reactions link.

Various methods have advantages and disadvantages, depending on the chemical compounds requiring treatment and the site’s hydrology. One of the consistent advantages of ozone groundwater remediation compared to other methods is:

• Equipment costs are affordable.
• Generating ozone on the premises removes the requirement to buy or transport dangerous chemicals.
• The installation process causes minimal disturbance to the site.
• The on-site profile is minimal.
• The operating expenses are low.
• The destruction of specific components takes place on-site.
• Significant reduction in soil and water contaminant mass and concentration can be observed within weeks, demonstrating impressive outcomes.
• Vapor control is unnecessary since the contaminants are destroyed instead of being transferred between phases.
• Microbubbles extract volatile organic compounds (VOCs) from groundwater and soil pores, leading to a decrease in soil oxidative demand.
• It is highly efficient in decomposing aromatic compounds.
• It can be merged with UV and/or peroxide to generate an advanced oxidation process, which must be carried out as a pump and treat operation. Ozone combined with UV offers the sole advanced oxidation process that does not necessitate the procurement, transportation, storage or handling of additional chemicals.
