| Details: | SUMMARY: Arsenic Treatment Options Tech Report DETAILS: System has an arsenic result over the MCL and Laura requested completing an SRF Letter of Interest (LOI). The running average (RRA) from the latest samples collected for 4 quarters was 0.015 mgl. This is over the MCL of 0.010 mgl. The latest sample collected on 7/6/10 was 0.0151 mgl. I reviewed the latest arsenic result and calculated the RAA. I also reviewed the Source Water Assessment prepared in 2002. The NOV requires completion by September 30, 2010. I talked to Laura earlier in the summer and nothing had been pursued at that time regarding treatment. I prepared the tech report and sent it to her for review.Respond as requested ACTION NEEDED: Respond as requested | ||
