Information for sampling sites in the U.S. Geological Survey (USGS) aquifer monitoring networks, Idaho National Laboratory and vicinity, Idaho.
sites
A SpatialPointsDataFrame of the sp package with 182 records and 21 variables:
site_no
USGS site number for monitoring well
station_nm
USGS site name
coord_meth_cd
latitude/longitude coordinate method code. The codes and their meanings are: "D" differentially corrected Global Positioning System (GPS), "G" mapping grade GPS unit (handheld accuracy range 3.7 to 12.2 meters), "L" long range navigation system, "M" interpolated from topographic map, and "S" transit, theodolite, or other surveying method.
coord_acy_cd
accuracy code for latitude/longitude values. The codes and their meanings are: "H" accurate to \(\pm\) 0.1 second, "5" accurate to \(\pm\) 0.5 second, "S" accurate to \(\pm\) 1 second, and "F" accurate to \(\pm\) 5 seconds.
alt_va
elevation of the land surface reference point, in feet above the North American Vertical Datum of 1988.
alt_meth_cd
method code for measuring elevation. The codes and their meanings are: "D" differentially corrected global positioning system, "L" level or other surveyed method, and "M" interpolated from topographic map.
alt_acy_va
accuracy of the elevation value (alt_va), does not account for vertical datum shift.
construction_dt
date the well was completed.
huc_cd
hydrologic unit code (HUC). Hydrologic units are geographic areas representing part or all of a surface drainage basin or distinct hydrologic feature and are delineated on the Hydrologic Unit Map.
reliability_cd
reliability code for data available for the site. The codes and their meanings are: "C" data have been checked by the reporting agency, and "U" unchecked data.
nat_aqfr_cd
national aquifer codes
aqfr_cd
aquifer codes defined by the catalog of aquifer names and geologic unit codes used by the Water Mission Area.
aqfr_type_cd
aquifer type code. The codes and their meanings are: "C" confined single aquifer, "M" confined multiple aquifers, "U" unconfined single aquifer, and "X" mixed (confined and unconfined) multiple aquifers.
well_depth_va
depth of the finished well, in feet below the land surface datum
hole_depth_va
total depth of the borehole, in feet below the land surface datum
depth_src_cd
source code for depth measurements. The codes and their meanings are: "A" reported by another government agency, "D" from driller's log or report, "G" private geologist-consultant or university associate, "L" interpreted from geophysical logs by personnel of source agency, "O" reported by owner of well, "R" reported by person other than the owner, driller, or another government agency, and "S" measured by personnel of reporting agency.
site_nm
local site name
completion_cd
borehole completion code. The codes and their meanings are: "O" open hole completion, "M" multilevel completion, and "P" open hole completion prior to multilevel completion.
network
aquifer monitoring network, either "aquifer" or "perched".
pos
a position specifier for site-labels on a map. Values of 1, 2, 3 and 4, respectively indicate positions below, to the left of, above and to the right of the site coordinates.
See projection
dataset for coordinate reference system information.
