Sand and gravel aquifers (glaciated regions)
Outwash
LOCATION - Lat 39°53'15.61", long 83°59'30.71" referenced to North American Datum of 1983, Clark County, OH, Hydrologic Unit 05080001,
REVISIONS HISTORY - A review of this record revealed that the land-surface correction applied to data from this well was in error from June 4, 2009 to April, 2016. The previous land-surface correction was 3.00 feet and a review of site records indicated that the appropriate land-surface correction is 2.27 feet. The site was surveyed with digital GPS in May-June, 2009. This survey determined the land-surface elevation at the well site was 847.81 feet and the measuring point elevation was 850.08 feet, resulting in a land-surface correction of 2.27 feet. All approved continuous and discrete water-level measurements during this period were edited based on the new land-surface correction.
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 180 ft. Upper casing diameter 4 in; top of first opening 140 ft, bottom of last opening 180 ft.
DATUM - Land-surface datum is 847.81 ft above North American Vertical Datum of 1988. Measuring point: Floor of instrument shelter, 2.27 ft above land-surface datum, Jan. 17, 2004 to present.
PERIOD OF RECORD - Periodic water level measurements 2003 to current year. Continuous hourly water level data June 2009 to current year.
