Ecosystem restoration and remediation are important for recovering from environmental harm and maintaining ecological equilibrium. For forensic sciences and environmental studies, these methodologies are essential for both estimating and remediating pollution, habitat destruction, and human impact. Forensic environmental investigation is a methodical analysis using scientific procedures, alongside the current legal requirements, for the purpose of identification of the origin of contamination according to causality principle and the subjects responsible for this contamination, in order to be used in the legal process relating to the environmental offenses. Sophisticated analytical methods such as remote sensing, GIS technology, and high-resolution mass spectrometry contribute to track pollutants commitment and ecosystem damage. The incorporation of forensic science into ecosystem restoration provides a means to undertake cost-effective, targeted remediation, based on evidence, thereby achieving a more efficient recovery of natural ecosystems. New technologies, including bioremediation, phytoremediation, and nanotechnology-based detoxification methods, are being developed for the restoration of polluted environment in an eco-friendly manner. AI and machine learning are also enhancing forensics by predicting patterns of contamination and seeking best matches for restoration efforts. Furthermore, forensic analysis on soil and water helps to understand the long-term environmental influences on ecology and assist a policy and enforcement approach. In this chapter, the convergence of forensic science with environmental analysis is considered, with a focus on the approaches employed to identify environmental damage, legal aspects of ecosystem degradation, and novel remediation technologies. Integrating forensic investigations with restoration science, the chapter is a study of the critical role played by interdisciplinary efforts to save environmental health and secure ecological justice.
