According to reporting from the Hindustan Times, the dogs were likely affected by untreated industrial waste that had been allegedly dumped by one company into the nearby Kasadi River. The river flows through an area with hundreds of factories, but the Times quoted officials who are blaming one factory whose name has not been released but which allegedly manufactures detergent. An investigation has been opened by the local regulatory agency, the Maharashtra Pollution Control Board, who will reportedly release a full report on the incident in the coming weeks.
