PHNOM PENH, April 24, 2026 (KPT) — Ministry of Environment of Cambodia has reported that water quality along the Mekong River remained within a “good” range during the first quarter of 2026, based on regular monitoring assessments.

Monthly evaluations were conducted at 11 monitoring stations across Stung Treng, Kratie, Kampong Cham, Kandal, Phnom Penh and Prey Veng, in cooperation with provincial departments of environment.

The assessments covered 12 parameters, including pH, dissolved oxygen, suspended solids, biochemical and chemical oxygen demand, nitrogen, phosphorus, nitrate and heavy metals such as cadmium, chromium, lead and mercury.

Results from January to March showed water quality across all monitored sites consistently met national surface water standards.

Environment Minister Eang Sophalleth said the Mekong remains a vital lifeline for Cambodia and maintaining its quality is a national priority.

He stressed that continuous monitoring ensures early detection of risks and supports public health and resource preservation.

Authorities reaffirmed their commitment to surveillance, enforcement and cooperation with institutions to safeguard the river.
