Details:	SUMMARY: Response to 12/1/17 DWS Letter DETAILS: Paul Odell called in response to a letter from our office sent on 12/1/17, which requested updated information and reminded the system of sampling requirements. Paul said that there were no changes to be made and that he thought that sampling had been up to date. I verified that sampling was in compliance for coliform, nitrate and arsenic. Arsenic for the wells (SRC-AB and SRC-AC) was last sampled in 2004 and the last sample for EP-A (when only the spring was in use) was in July 2000. All arsenic samples were analyzed using EPA method 200.8 with a minimum detection limit of 0.0005 mg/l, therefore, the one-time sampling requirement for arsenic was deemed to be fulfilled. ACTION NEEDED: No further action needed.
