At 4:14 am on August 25, 2010, the clerk at USA 234 (Santa Ana) called the Stratus emergency phone number to report water spraying from the groundwater treatment system compound. Stratus staff received the call from the emergency phone number, and Stratus was on site at approximately 4:45 am.  Stratus observed approximately 5 gallons of water on the concrete paving east of the compound, but no water from the system was observed to have flowed off-site. The system was immediatly shut down at the main power supply.  Additional staff arrived at 4:55 am, the compound was unlocked and the concrete inside was found to be damp but there was no ponded water.  An obvious source of the leak could not initially be identified.  The system was temporarily reactivated, and a pinhole leak was discovered in the process hose at the outlet of the manifold (between the manifold and the inlet of the first carbon vessel). The system was then shut down and lock out/tag out (LOTO) was applied pending replacement of the damaged hose.
