SAN JOSE, Calif. (AP) - The agency that supplies much of Silicon Valley with drinking water is facing possible civil prosecution for repeatedly spilling hydraulic oil in its reservoirs.

     

In a letter to the Santa Clara Valley Water District, county prosecutors say the spills were serious. The letter - dated March 29 - warns that civil prosecution is appropriate although the District Attorney's Office has not filed a case in court.

     

Water district officials say the spills were small and caused no environmental damage. Tests did not show elevated levels of petroleum products in drinking water.

     

District records show eight hydraulic oil spills ranging from 5 to 35 gallons since 2001.

     

Water district officials say the leaky hydraulic systems that caused at least some of the spills will be repaired over the next decade.
