Abstract
Groundwater remediation is the process of treating contaminated groundwater by removing contaminants or converting them to harmless chemicals. Water that saturates the pore space in the subsurface and is located beneath the ground surface is known as groundwater. Between 25% and 40% of the world’s drinking water comes from boreholes and dug wells. Farmers need groundwater to irrigate crops, while industry use it to make everyday items. Even though most groundwater seems pure, it can be contaminated as a result of natural forces. People produce several waste materials and byproducts as a result of their numerous and various actions. Traditionally, there haven’t been many regulations governing the disposal of such trash. consequence, garbage is routinely deposited or kept on land surfaces, where it seeps into the groundwater under. Like a consequence, contaminated groundwater is unfitted for human consumption. Overuse of fertiliser or pesticides, spills from industrial activities, infiltration from urban runoff, and landfill leakage are all examples of current practises that can have an influence on groundwater. The usage of contaminated groundwater poses a threat to public health by causing poisoning or the spread of disease, and aquifer restoration was already created to tackle these issues. Physically, inorganic chemical, organic chemical, bacteriological, and radioactive characteristics are all found in groundwater contaminants. Pollutants and pollutants can be removed from groundwater using a variety of processes, bringing the water up to a quality suitable for a variety of purposes.
