In mlms: Multilevel Monitoring System Data for Wells in the USGS INL Aquifer Monitoring Network

MLMS Wells

Description

A spatial dataset describing the location of wells equipped with a Multilevel Monitoring System (MLMS) in the U.S. Geological Survey (USGS) aquifer-monitoring network, Idaho National Laboratory (INL), Idaho.

Usage

wells

Format

A spatial feature data frame with the following variables:

site_nm

Local site name for a MLMS well.

coord_acy_va

Accuracy of latitude/longitude value, in seconds.

alt_va

Altitude of the land surface reference point (also known as the brass cap), in feet above the North American Vertical Datum of 1988 (NAVD 88).

alt_acy_va

Accuracy of the altitude value, in feet.

etape_cf_va

E-tape correction factor determined through calibration, in feet.

deviation_cf_va

Borehole deviation correction factor, in feet.

stickup_va

Stick-up distance, the height of the well casing that extends above the land surface measurement point, in feet.

mp_b_va

Distance between the top and bottom of an inflated packer seal, in feet.

mp_c_va

Distance between the transducer plane and the measurement port inlet valve, in feet.

hole_depth_va

Total depth to which the hole is drilled, measured as the distance below the land surface reference point, in feet below land surface (ft bls).

well_depth_va

Depth of the finished well, in ft bls.

construction_dt

Date the well was completed.

install_dt

Date the MLMS was installed.

system_tp

Multiport monitoring system type. Two versions of the Westbay System were utilized in this study: the "MP55" and the "MP38".

nzones

Number of depth-discrete monitoring zones.

nports

Number of measurement ports.

nvisits

Count of field visits for pressure profiling.

geometry

Zero-dimensional geometry containing a single point.

Source

The dataset originates from the USGS INL Project Office and underwent processing using the read_mlms_json function.
