The contamination of water sources by diverse pollutants poses a substantial peril to both human well-being and environmental integrity. In this context, in-situ remediation strategies have emerged as noteworthy and cost-efficient methods to address water pollution sustainably. This review paper aims to furnish a comprehensive and holistic perspective on various in-situ remediation techniques deployed for treating polluted water. The paper extensively delves into the fundamental principles, benefits, limitations, and real-world instances of distinct in-situ remediation approaches. These encompass bioremediation, phytoremediation, chemical oxidation/reduction, and the utilization of permeable reactive barriers. The review emphasizes the pivotal significance of selecting the most suitable strategies, taking into account specific site conditions and the unique attributes of the pollutants. Additionally, the paper contemplates the challenges at hand and outlines prospective pathways for advancing in-situ remediation methods in the future.
