Sand and gravel aquifers (glaciated regions)
Glacial Surficial Sand and/or Gravel
LOCATION - Lat 45°26'37.33", long 93°55'16.71" referenced to North American Datum of 1983, in NW 1/4 NW 1/4 NW 1/4 sec.14, T.34 N., R.29 W., Sherburne County, MN, Hydrologic Unit 07010203, The well is located to the northeast of the house approximately 115 ft. The well is located just west of a wooden fence that goes around the parameter of the homeowner's yard. The well is also approximately 115 ft. south of 87th St, where the wooden fence runs perpendicular to 87th St.
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 15.66 ft. Upper casing diameter 2 in; top of first opening 10.66 ft, bottom of last opening 15.66 ft. The hole for well ALUS-07 was drilled with an 8.25-inch-diameter, hydraulic rotary drill rig, on 18 September 1997 to a depth of 16 feet. The well is constructed of a 5-feet-long, 2-inch-diameter, schedule-40 PVC, 0.010-inch slotted, flush-threaded screen attached to about 10.5 feet of 2-inch-diameter, schedule-40 PVC casing. The casing stickup was 1.76 feet above land surface on 01 August 2012. The open interval of the well is 10.5 - 15.5 feet below land surface and the total well depth is 15.66 feet.
DATUM - Land-surface datum is 973.98 ft above North American Vertical Datum of 1988. Measuring point: top of casing, not protection casing and/or post, 1.76 ft above land-surface datum, Jan. 1, 2006 to present. The current measuring point is a black mark on the top of the PVC well casing (not protection post), which was 1.76 feet above land surface on Aug. 02, 2012. Elevation of that measuring point was 975.74 plus-or-minus 0.03 feet above sea level, North American Vertical Datum of 1988, based on a RTK GPS survey on Sept. 18, 2012.
PERIOD OF RECORD - Water levels are recorded periodically from 18 September 1997 to the present. Hourly water levels were recorded from 11 September 2012 at 16:00 CDT to 04 November 2014 at 12:00 CST.
GAGE - Continuous water level, water temperature, and battery voltage were measured with an OTT Orpheus Mini 0-4m pressure transducer on Sept. 11, 2012 at 16:00 CDT. These data were recorded hourly by the same OTT Orpheus Mini pressure transducer, which had a datalogger built into it. The datalogger was housed inside of the 2-inch PVC well casing, which has an aluminum locking well cap on top of that. The gage was powered by 3 AA lithium batteries that were inside of the communications rod. Data was downloaded manually and no telemetry or phone line was wired into the gage.

An unheated Onset RG3 tipping-bucket raingage was added to the station on Sept. 11, 2012 at 15:30 CDT. The raingage was mounted on a green T-post, located approximately 40 ft. southwest of well ALUS-07. The raingage had a built-in datalogger, which measured and recorded precipitation quarter-hourly. Raingage was nominally accurate to 0.01 inches.

The pressure transducer and raingage were removed from the site on Nov. 04, 2014, due to data collection completion for the I-94 Growth Corridor project.

This well is not currently gaged. Only visited periodically to measure discrete groundwater levels and periodically collect discrete water quality samples.
COOPERATION - This site is operated by the U.S. Geological Survey as a monitoring well for the Upper Mississippi (UMIS) National Water-Quality Assessment (NAWQA) program. This well is included in the UMIS NAWQA Agricultural Land-Use Study (ALUS) network. The well was incorporated into the I-94 Growth Corridor Study during August 2012 to November 2014. The I-94 Growth Corridor Study was a collaborative effort between the Minnesota Department of Natural Resources and the U.S. Geological Survey.
CLIMATOLOGICAL RECORDS
PERIOD OF RECORD - Quarter-hourly precipitation were recorded from 11 September 2012 at 15:30 CDT to 04 November 2014 at 12:30 CST, except during the following period:

During 15 June 2014 at 00:15 CDT to 11 July 2014 at 02:30 CDT, hourly precipitation data is missing due the rain gage not recording accurate data. It is suspected that the rain gage may have tipped over or wasn't level during this period. The homeowners moved the rain gage on 02 May 2014 and didn't mount it securely at its new location. It appears the rain gage became accurate again after 11 July 2014 at 02:30 CST. The hourly data during this period were deleted. Daily sums during this period were accurately estimated based on nearby I-94 Corridor project precipitation data.
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.
