Abstract
Yangon Port is the primary maritime transport to international trades through Yangon river wa-terway. High rate of sediment deposition in a confluence of rivers, namely an inner bar, has hin-dered navigation channel approaching Yangon Port. Thus, maintenance dredging at inner bar has been carried out annually. Owing to Myanmar Port Authority assuming dredged materials as wastes and focusing on ship to pass easily, dredged materials are directly dumped into open water area closed to dredging area without any disposal site monitoring and assessment of sediment contamination. This research aims to minimize volume generated annually by appropriate benefi-cially use-methods approaching sustainable dredging practices. Thus, sediment samples were collected from 3 different locations in inner bar area and analyzed following U.S. EPA test meth-ods or other relevant methods. Particle size distribution, organic matters, heavy metals, and per-sistent organic pollutants were evaluated. 14% of sand, 32% of silt, and 54% of clay were ob-tained from particle sizing results. Lower values of heavy metals, Polycyclic aromatic hydrocar-bon, and Polychlorinated biphenyls than sediment quality criteriaof various countries were found. Therefore, these sediments may be supposed being non-contaminated and reused without additional pollution-control treatments. Particle separation and dewatering techniques were de-scribed as cost-effective m
