DATUM - Land-surface datum is 1,955.14 ft above North American Vertical Datum of 1988. Measuring point: Black mark on top of casing north side, 0.15 ft above land-surface datum, Oct. 15, 2006 to present; OLD TOC- All WL's corrected to new MP's, 0.55 ft below land-surface datum, Oct. 15, 2006 to Oct. 16, 2006; OLD Vault- All WL's corrected to new MP's, 0 ft above land-surface datum, Oct. 15, 2006 to Oct. 16, 2006; X on lip of steel vault south east side, 0.66 ft above land-surface datum, Oct. 15, 2006 to present. Prior to August 19, 2021, land-surface datum was 1,954.53 ft above North American Vertical Datum of 1988.
REMARKS -

On 8/19/21 previous survey data was reprocessed and resulted in a 0.61 change in elevation causing a jump in the hydrograph for groundwater elevation.

Static water-level on 12-09-2021 was incorrectly entered and approved as 483.39 ft. below land surface datum. Upon review of field notes and continuous water-level data it was corrected to 484.38  ft. below land surface datum effective 3-4-2021.
