- Today he will complete the pre-populated public notice template, date it, post it around the nursery, and return a copy to DWS.
- Continue on quarterly arsenic testing, with the next test due in 3rd quarter 2019
- Research treatment options and submit fee and materials to DWS for plan review prior to purchasing or installing a unit. He is looking at a point of use device. Treatment will be required as the 4 quarter average exceeds the maximum contaminant level of 0.010 mg/L, given a high result in 1st quarter 2019.
