More than two months after he was placed on leave by the board of California’s largest urban water supplier, embattled General Manager Adel Hagekhalil defended his performance and insisted the accusations against him are unfounded.

The board of the Metropolitan Water District of Southern California met in closed session Tuesday to discuss the status of investigations into multiple complaints and voted to extend Hagekhalil’s leave of absence until Oct. 23 as the investigation continues. The leave had been scheduled to end in September.
