Details:	SUMMARY: Arsenic over the MCL at .0113 DETAILS: I spoke with Walt Tabrum and Pete Peterson. Walt asked about using the RAA for arsenic. Since the sample was over the MCL and the 3rd quarter sample was missed the system needs to stay on quarterly monitoring for arsenic. Walt said they would change the resin tin the treatment units. ACTION NEEDED: System needs to continue quarterly monitoring before a reduction to annual can be made. Monitor future sampling to establish a reduced schedule.
