Details:	SUMMARY: Combined GW Source Coliform Smapling Request DETAILS: I reviewed the SWAP report and the 2009 Water System Survey and the 3 springs appear to produce water from the same "Hydrogeologic Setting", which is described in the Source Water Assessment Report as the Paleocanyon Componentof the Maupin Paleocanyon Aquifer. The water system would need to sample at a location representative of the water combined from the three springs. If EC+ is detected at the combined sample location, then 5 confirmation EC+ samples would need to be collected from at each active spring within 24 hours. ACTION NEEDED: None at this time.
