USGS Groundwater Videos: Groundwater Technical Procedures Videos

The USGS Water Mission Area released a series of groundwater technical procedures documents (GWPDs) for general use by the public. These technical procedures were written in response to the need for standardized technical procedures of many aspects of groundwater science, including site and measuring-point establishment, measurement of water levels, and measurement of well discharge. To supplement these technical documents, USGS is producing a series of videos demonstrating some of the technical procedures outlined in the GWPDs.

The following USGS GWPD videos are available:

Measuring Water Level with Steel Tape

GWPD 1 -- Measuring water levels by use of a graduated steel tape

Purpose: To measure the depth to the water surface below land-surface datum using the graduated steel tape (wetted-tape) method.

Download the steel tape measurement video or transcript from the USGS multimedia gallery.

Measuring Water Level with Electric Tape

GWPD 4 -- Measuring water levels by use of an electric tape

Purpose: To measure the depth to the water surface below land-surface datum using the electric tape method.

Download the electric tape measurement video or transcript from the USGS multimedia gallery.

Measuring Water Level in a Flowing Well (low pressure)

GWPD 12 -- Measuring water levels in a flowing well

Purpose: To measure low-pressure hydraulic head in flowing wells.

Download the video or transcript for measuring water level in a flowing well (low pressure) from the USGS multimedia gallery.

Redevelop Groundwater Monitoring Wells -- Air Lift Method

Purpose: To redevelop a groundwater monitoring well using the air lift method
