Toxic effluent on the Prachin River (Kabin Buri to Ban Sang) killed wild and caged fish. Cage tilapia farmers report losses of 700,000 baht or more per farm, and some sold fish at 20-25 baht/kg versus about 100 baht normally. The provincial meeting resolved to propose closing two factories to the Department of Industrial Works, and the Department of Fisheries will test carcasses for contaminants. Farmers say compensation is not realistic and warning systems are missing. If you run a business along this river or source fish or water from it, check your exposure, keep records of losses for any compensation claim, and watch for stricter discharge enforcement in the area.
