Authorities Investigate 200 Tons of Abandoned Aluminum Dross in Samut Sakhon

On October 16, 2026, Suchart Chomklin, the Minister of Natural Resources and Environment, directed the Pollution Control Department (PCD) to investigate the storage of approximately 200 tons of aluminum dross. The waste was found both inside and surrounding a warehouse at a closed factory in Na Di sub-district, Samut Sakhon province.

According to Khaosod Online, the PCD, in coordination with the Department of Special Investigation (DSI) and local environmental and industrial offices, conducted air and water quality tests in the vicinity. Initial measurements of ammonia (NH₃) gas at eight points inside the warehouse ranged from 0 to 5 ppm. Further testing was conducted at seven additional points within a 100 to 500-meter radius of the site.

For residents and visitors in the area, this situation highlights potential environmental risks associated with industrial waste mismanagement. While authorities are actively working to mitigate health and environmental impacts, the long-term safety of the site remains under assessment. It is currently unconfirmed whether the waste has caused any soil or groundwater contamination beyond the initial air quality readings. Residents are advised to monitor local government updates regarding the cleanup progress and any potential health advisories as the investigation continues.
