Official reports said 50,000 L (310 bbl) of oil were spilled, but critics of the oil company and the government say that the spill was much larger and warned of health risks posed both by the spill and by the chemicals being used to disperse the oil.[12]
A higher estimate of the oil spill has been performed by Somporn Chuai-aree of Prince Songkhla University: "as low as 108,000 L (680 bbl) or as high as 190,000 L (1,200 bbl)".[4] This estimate is believed by associate professor Siwat Pongniumchan from the National Institute of Development Administration (Nida), who disbelieves previous estimates.
