Bang Pakong River's 'Two-Color Crisis' Devastates Dolphin Watching Boats and Cage Aquaculture

A 'two-color' phenomenon, accompanied by an unusual odor, has emerged in the Bang Pakong River in Chonburi Province, eastern Thailand, causing severe repercussions for the local economy. This phenomenon, where the river water loses its natural color and exhibits an abnormal hue, is raising significant concerns among local residents and industry stakeholders. The situation has dealt a devastating blow particularly to operators of dolphin watching tours and fishermen engaged in cage aquaculture along the riverbanks. Tourists are avoiding tours on the polluted river, and the aquaculture fish are threatened by the contaminated water quality, jeopardizing their survival. Consequently, these industries, which have long supported the regional economy, are facing a crisis of decline. While the exact cause of this 'two-color' phenomenon has not yet been identified, the influx of industrial and domestic wastewater is suspected. Thai authorities have initiated efforts to address the situation and investigate its cause, but given the severity of the problem, swift and effective measures are urgently needed. The Bang Pakong River is a vital water resource for Chonburi Province and is indispensable to the livelihoods and economic activities of the local population. Resolving this water pollution issue is an immediate priority for the sustainability of the local community.
