GROUNDWATER RECORDS

WELL CHARACTERISTICS - Depth 18 ft. Upper casing diameter 1.25 in; top of first opening 14.94 ft, bottom of last opening 16.94 ft. Well LH-01 is a groundwater observation well that was drilled on 02 Sept. 1970 with an unknown diameter, with unknown drilling equipment to 22 feet. The well is constructed of a 2-feet-long, 1.25-inch-diameter, steel, 0.018-inch slotted, Johnson redhead sand point well screen, attached with to length/s of 1.25-inch-diameter, steel well casing. The well casing measuring point (stickup) was 0.98 feet (1208.74 ft. NAVD88, +/- 0.96 ft.) above land surface when measured on 05 Mar. 2020. The well casing measuring point/stickup was extended on to 3.01 ft. (1210.77 ft. NAVD88 +/- 0.96 ft.) about land surface on 05 Mar. 2020. The open interval of the well is between 16 and 18 feet below land surface and the total well depth (according to drillers log) is 18 feet below land surface. The total well depth was sounded (solid bottom) at 16.94 ft. BLS after a well re-development attempt on 05 Mar. 2020.

DATUM - Land-surface datum is 1,207.76 ft above North American Vertical Datum of 1988. Measuring point: Original MP/stickup according to old paper notes/files. Much different than 3/5/2020 meas, 2.0 ft above land-surface datum, Sep. 2, 1970 to Mar. 4, 2020; Top of 1.25-inch diameter steel well casing. Measured on 3/5/2020, 0.98 ft above land-surface datum, Mar. 4, 2020 to Mar. 5, 2020; MP extended on 3/5/2020. Top of 1.25-inch diameter galvanized steel well casing, 3.01 ft above land-surface datum, Mar. 5, 2020 to present. The current measuring point is a black mark on the top of the 1.25-inch diameter steel well casing, which was 3.01 feet above land surface on 05 Mar. 2020. Elevation of the measuring point is 1210.77 plus-or-minus 0.96 feet above sea level, North American Vertical Datum of 1988, based on Digital Elevation Model (DEM) data. The well MP/stickup was extended from 0.98 ft. to 3.01 ft. on 05 Mar. 2020 to accommodate the real-time equipment and infrastructure that was installed at the site on 05 Mar. 2020. This longer MP/stickup also makes it's easier to locate the well in the tall grass and along the tree-line, which is not that far away from the shoulder of Co. Rd. 13.

The old measuring point was a black mark on the top of the 1.25-inch diameter steel well casing, which was 0.98 feet above land surface when measured on 05 Mar. 2020. Elevation of the measuring point is 1208.74 plus-or-minus 0.96 feet above sea level, North American Vertical Datum of 1988, based on Digital Elevation Model (DEM) data.

The original measuring point was the top of the 1.25-inch diameter steel well casing, which was 2.0 feet above land surface when measured on 02 Sept. 1970. Elevation of the measuring point is 1209.76 plus-or-minus 0.96 feet above sea level, North American Vertical Datum of 1988, based on Digital Elevation Model (DEM) data.

PERIOD OF RECORD - Water levels were recorded periodically from 16 October 1970 to 02 November 2021. Water levels were recorded hourly from 05 March 2020 at 15:00 CST to 17 April 2020 at 07:00 CDT. Water levels were recorded quarter-hourly from 17 April 2020 at 08:30 CDT to 20 Oct. 2020 at 18:00 CDT. Water levels were recorded hourly from 20 Oct. 2020 at 19:00 CDT to 03 Feb. 2021 at 16:00 CST. Water levels were recorded quarter-hourly from 03 Feb. 2021 at 16:45 CST to 02 November 2021 at 15:45 CDT.

GAGE -

Water level and water temperature were measured with a Campbell Scientific, Inc. CS451, 0-16.7 ft. range, submersible pressure transducer nominally accurate to 0.01 feet and 0.1°C, respectively. Water level, water temperature, shelter temperature, and battery voltage were all recorded by a Campbell Scientific, Inc. CR300 data logger, which recorded all data hourly. The data logger was housed in a 14-inch X 16-inch grey fiberglass shelter attached to 8 ft. tall, 1.25-inch diameter steel mast. The gage was powered by two 20W solar panel and was telemetered by an Sierra Wireless RV50X cellular modem with a magnetic mounted Laird TRA6927M3NB-001, Low Profile NMO Antenna, Phantom Shot Glass Style Antenna.

An unheated Onset RG3 rain gage (primary) was added to the station during 17 Apr. 2020 at 10:45 CDT to 02 Nov. 2021 at 16:45 CDT. The rain gage was mounted on a fence post approximately 250 ft. NE of the real-time station, along a power line. This rain gage recorded quarter-hourly rainfall data. Rain gage was nominally accurate to 0.01 inches.

All monitoring equipment was removed from the site on 02 Nov. 2021 at 16:45 CDT. This site has been discontinued for the USGS/MDH Pathogens study.

COOPERATION - This site was operated (1970-1992) by the U.S. Geological Survey as a monitoring piezometer for the USGS Hydrologic Atlas Report Series. This site (MN obwell #18000) is currently operated from 1995 to the present by the Minnesota Dept. of Natural Resources as a monitoring well for MN-DNR Cooperative Groundwater Monitoring program.  This site was operated from 05 March 2020 to 02 November 2021 by the U.S. Geological Survey as a monitoring well for the USGS/MDH Automated Virus Sampler Study. The USGS/MDH Automated Virus Sampler study was a collaborative study between the Minnesota Dept. of Health and the U.S. Geological Survey.

CLIMATOLOGICAL RECORDS

PERIOD OF RECORD - Precipitation data were recorded quarter-hourly from 17 April 2020 at 10:45 CDT to 02 November 2021 at 16:45 CDT.

INSTRUMENTATION -  Precipitation was measured with an Onset RG3 tipping-bucket rain gage, which is accurate to 0.01 inches. The rain gage was unheated and uncovered during the winter. Thus precipitation data during freezing periods (about December through early April) result from melting of snow during warm periods and do NOT represent actual precipitation.
