Water pollution caused by synthetic dyes (including azo, cationic, and anthraquinone dyes) and heavy metals (Pb, Cd, Cr, Cu, Ni, and Zn) presents a significant environmental challenge, necessitating effective and sustainable remediation strategies. This review explores the potential utilization of marine sediments from the neritic zone as an alternative adsorbent for the removal of these contaminants. This review focuses on neritic (shelf) marine sediments. These materials are abundant, accessible, and mineralogically reactive. When responsibly sourced and governed, they offer a practical pathway for dye and heavy metal removal in saline and brackish waters. The study examines the physicochemical properties of neritic sediments, their adsorption mechanisms, and modification techniques to enhance their pollutant removal efficiency. Furthermore, the review evaluates the feasibility of integrating marine sediments into wastewater treatment applications, emphasizing their alignment with Sustainable Development Goals (SDGs), particularly in achieving clean water and environmental sustainability. The findings indicate that marine sediments can serve as a cost-effective and environmentally friendly adsorbent, with modification strategies such as acid/base treatment, thermal activation, and biofunctionalization further improving their performance. Challenges such as pollutant desorption, variability in sediment composition, and potential ecological impacts are also discussed, providing insights into future research directions and the scalability of sediment-based treatment systems. Overall, this review highlights the promising role of marine sediments from the neritic zone in water pollution control, offering an innovative approach to addressing global environmental concerns.
