This reports on the results of the monitoring of water quality across 48 stations in the LMB. The report shows the water quality in the Mekong and Bassac Rivers was still of good quality with the slight improvement compared with 2016. There was only a small number of measurements of chemical oxygen demand (COD) and dissolved oxygen (DO) that violated the MRC Water Quality Guidelines for the Protection of Human Health (WQGH) and the MRC Water Quality Guidelines for the Protection of Aquatic Life (WQGA). Most exceedances were recorded in the Delta. Of a slight concern was the DO level at Chau Doc, which violated the WQGH for all sampling occasions causing water quality for the protection of human health to be downgraded from ‘good’ in 2017 to ‘moderate’ in 2018.
