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

Measurement Ports

Description

Dataset describing the locations of measurement ports within the multilevel completions of wells in the U.S. Geological Survey (USGS) aquifer-monitoring network, Idaho National Laboratory (INL), Idaho. These valved measurement ports enable monitor groundwater outside the multiport casing and within a monitoring zone.

Usage

ports

Format

A data frame with the following variables:

site_nm

Local site name for a MLMS well.

port_nu

Identifier for the valved measurement port.

site_no

USGS site identification number.

mp_a_va

Distance between the transducer plane and the bottom of the adjacent upper packer (top of the monitoring zone), in feet, as documented in the system log. A value of not applicable (NA) indicates a optional lower port coupling within the monitoring zone.

wl_depth_va

Depth to water inside the multiport casing measured using an electric tape (e-tape), in feet below the top of the well casing.

baro_compl_va

Atmospheric pressure measured at land surface, in pounds per square inch (psi).

temp_compl_va

Fluid temperature measured inside the multiport casing at the pressure transducer bridge, in degrees Celsius (°C).

press_compl_va

Absolute pressure of fluid inside the multiport casing, in psi.

tp_depth_va

Depth to the transducer plane in the measurement port coupling, in feet below land surface.

port_depth_va

Depth to the measurement port inlet valve of a port coupling, in ft bls.

port_alt_va

Altitude of the measurement port inlet valve of a port coupling, in feet above the North American Vertical Datum of 1988 (NAVD 88).

zone_nu

Identifier for the depth-discrete monitoring zone, where groundwater in this zone is vertically isolated between upper and lower packers.

npress

Number of pressure and temperature measurements collected at the port.

nsamples

Number of water-quality samples collected at the port.

Source

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