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
Purpose: To measure the depth to the water surface below land-surface datum using the graduated steel tape (wetted-tape) method.
Establishing a Permanent Measuring Point and Reference Marks at a Well
Purpose: To establish a permanent measuring point at a well from which water levels are measured, to establish a permanent land-surface datum, and to establish nearby reference marks.
Measuring Water Level with Electric Tape
Purpose: To measure the depth to the water surface below land-surface datum using the electric tape method.
Measuring Total Well Depth Using a Steel Tape
Purpose: To measure the total depth of a well below land-surface datum by using a weighted graduated steel tape
Measuring Water Level in a Flowing Well (low pressure)
Purpose: To measure low-pressure hydraulic head in flowing wells.
Redevelop Groundwater Monitoring Wells -- Air Lift Method
Purpose: To redevelop a groundwater monitoring well using the air lift method
