Abstract

Abstract: Groundwater contamination is a problem in several areas around the world, notably in the industrial belts. For people all across the world, groundwater is a vital source of water. Physical, chemical, and biological aspects determine the amount and quality of groundwater for human consumption and irrigation. People in some parts of the world are experiencing true water scarcity because groundwater is used faster than it is regularly recharged. Groundwater contamination must be remediated, because people's general well-being and prosperity are inextricably linked to their ability to obtain sufficient amounts of high-quality water. This study is an attempt to have insight into the role of nanotechnology for groundwater remediation. This study shows that nano remediation has the ability to minimize time and lower pollutants concentration to near zero by cleaning contaminated areas in situ . However, there are questions about safe disposal and long-term impact on the environment. Green Nanoparticles (GNP) are an alternative that are made with environmentally friendly procedures and materials, resulting in less waste. They also have the advantage of being environmentally friendly and sustainable. HIGHLIGHTS: This technology is advancing fields of research and development in the context of environmental purification. Nano remediation has a wide application in groundwater remediation with a continual rise in related research and development. Nano remediation has high potential to remediate huge sites in-place, cutting cleanup time and removing the requirement for contaminant removal, lowering contamination concentrations to near zero.
