USGS Water-Year Summary 2024
444630095002209 OB-7 Olivia Field Site 0000773079
Glacial Buried Sand and/or Gravel
LOCATION - Lat 44°46'30.33", long 95°00'21.76" referenced to North American Datum of 1983, Renville County, MN, Hydrologic Unit 07020004, The well is located in Olivia, MN. The well is located in a city park and camping area, 85 ft. east of the City of Olivia water tower. The well is located approximately 0.5 miles SW of the intersection of MN HWY 212 (Lincoln Ave.) and MN HWY 71 (13th St.).
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 209.76 ft. Upper casing diameter 2.07 in; top of first opening 204.92 ft, bottom of last opening 209.71 ft. The hole for well OB-7 was drilled with an 6.75-inch-diameter, rotosonic drill rig to a depth of 230.0 feet. The well is constructed of a 4.79-feet-long, 2-inch-diameter, schedule-40 stainless steel, 0.010-inch slotted, Johnson well screen, attached with threaded black steel couplings with length/s of 20.00 feet of 2.07-inch-diameter, schedule-40 black steel well casing. The well casing measuring point (stickup) was 2.73 feet (1074.12 ft. NAVD88, +/- 0.05 ft.) above land surface when measured on 01 Aug. 2017. The open interval of the well is between 204.92 and 209.71 feet below land surface and the total well depth is 209.76 feet below land surface.

This observation well is open to the same aquifer that two nearby municipal wells pump multiple times per day to meet the water demand for the City of Olivia.
DATUM - Land-surface datum is 1,071.39 ft above North American Vertical Datum of 1988. Measuring point: Black mark on top of 2-inch diameter steel well casing, not protection post, 2.73 ft above land-surface datum, Aug. 1, 2017 to present. The measuring point is a black mark on the top of the 2.07-inch black steel well casing, which was 2.73 feet above land surface on 01 Aug. 2017. Elevation of the measuring point is 1074.12 plus-or-minus 0.05 feet above sea level, North American Vertical Datum of 1988, based on historical differential GPS data and an optical survey on 24 Oct. 2017.
PERIOD OF RECORD -

Water levels were recorded periodically from 08 Aug. 2017 to 10 Oct. 2018. Water levels were recorded quarter-hourly from 03 Nov. 2017 at 15:15 CDT to 23 May 2018 at 17:00 CDT. Water levels were recorded every 1-minute from 23 May 2018 at 17:18 CDT to 01 Jun. 2018 at 11:04 CDT. Water levels were recorded quarter-hourly from 01 Jun. 2018 at 11:15 CDT to 10 Jul. 2018 at 19:00 CDT. Water levels were records every 1-minute from 10 Jul. 2018 at 19:13 CDT to 13 Jul. 2018 at 07:23 CDT. Water levels were recorded quarter-hourly from 13 Jul. 2018 at 07:45 CDT to 10 Oct. 2018 at 15:15 CDT.

GAGE -

Continuous water level, water temperature, and battery voltage were measured with an OTT Orpheus Mini 0-20m pressure transducer. These data were recorded hourly by the same OTT Orpheus Mini pressure transducer, which had a data logger built into it. The data logger was housed inside of the 2.07-inch black steel well casing, which has an aluminum locking well cap on top the 6-inch black steel protection post. The gage was powered by 3 AA alkaline batteries that were inside of the data logger communications rod. Data was downloaded manually and no telemetry or phone line was wired into the gage.

The pressure transducer and data logger were removed from the well on 10 Oct. 2018 at 15:15 CDT. Data collection for the Confining Beds "phase 2" study have concluded and all data logging equipment have been removed from the sites.

COOPERATION - This site is operated (2017-2018) by the U.S. Geological Survey as a monitoring piezometer for the Glacial Confining Beds Study. The well was used as part of the Glacial Confining Beds Study during 01 August 2017 to 10 October 2018. The Confining Beds Study is a collaborative effort between the Environment and Natural Resources Trust Fund, Iowa State University, Minnesota Geological Survey, and the U.S. Geological Survey.
