California American Water Distributes Annual Consumer Confidence Report

LOS ANGELES, June 26 /PRNewswire/ -- During the month of June, California
American Water customers in Southern California will receive a Consumer
Confidence Report. Most reports will be direct mailed to customers' homes;
however, some will arrive as an insert in customers' water bills. The
reports, which are required for the majority of water systems in the United
States by the Environmental Protection Agency, aim to educate customers about
where their water comes from and what's in it.

"Our customers are our top priority. The water we delivered in 2008 met or
surpassed all state and federal standards," stated California American Water
Southern California General Manager Todd Brown. "We're also committed to
providing the infrastructure replacements and improvements needed to deliver
trusted water service and comply with new regulations now and for years to
come."

Consumer Confidence Reports provide detailed information about each
community's drinking water source, the treatment it requires and the results
of testing and measurements for over 100 compounds and constituents. The
reports contain data for water provided in the previous calendar year.

The reports are also available at: www.californiaamwater.com. Renters who do
not receive a copy of the Consumer Confidence Reports are encouraged to access
the reports online. Customers with questions concerning their Consumer
Confidence Report are encouraged to contact California American Water at:
1-888-237-1333 or the Environmental Protection Agency Safe Drinking Water
Hotline at: 1-800-426-4791.
