Water Quality Reports 

Since 1990, California water utilities have been providing an annual Water Quality Report to their customers by July 1st of every year. This year's report has been prepared in compliance with regulations called for in the 1996 reauthorization of the Safe Drinking Water Act.

TCWD no longer mails hardcopies of the Water Quality Report to customers. If you would like a hardcopy of the current Water Quality Report, please feel free to stop by the District Administrative Facility or contact Customer Service at (949) 858-0277.
