Thai ethanol plant found to have likely killed giant stingrays due to wastewater leak

In Thailand, following lab tests confirming that molasses contains ammonia that could kill giant stingrays as happened recently in the Mae Klong River, the Pollution Control Department is preparing to launch a formal complaint against Rajburi Ethanol for illegally discharging molasses-containing wastewater into the river between October 1 and 7.  The company admitted there had been a wastewater leak on September 30. The wastewater is thought to then have been lodged into a part of the river that couldn’t move due to high tide, suffocating aquatic life including the stingrays.
