Details:	I spoke with Larry regarding corrosion control treatment and the three excursions for phosphate (as PO4) in July 2018 in the distribution system. The minimum set point for phosphate is 0.4 mg/L. He indicated there was a problem with the instruments at the Marks Well and adjustments were based on erroneous measurements. Once staff re-adjusted and double-checked the instruments, additional measurements verified the problem as corrected. No further action needed at this time.
