This animated infographic shows how aquifer compaction can lead to land subsidence. When water is pumped from a confined aquifer faster than it can recharge, the water pressure in the aquifer begins to decrease. As water pressure decreases, both the confining layers and the aquifers themselves can start to compact under the weight of the overlying sediments.

This static map shows the locations of the three existing extensometers (red) in the USGS' Virginia Extensometer Network with the location of a fourth future extensometer (green). The basemap is of the Virginia Coastal Plain and shows the severity of groundwater depletion, with darker blue indicating greater groundwater depletion.

Photograph of a clay pad used in monitoring sediment deposition. Once installed, the amount of sediment deposited atop the clay pad can be periodically measured. Sediment deposition is monitored along the Long Branch creek in Fairfax County, Virginia as a part of the Fairfax County Water Resources Monitoring Network.

Equipment used for water-quality sampling needs thoroughly cleaned to remove lingering contaminants or sediment. In this photo, a peristaltic pump is used to flush three different solutions (liquid detergent, tap water, and deionized water) through the tubing used to collect raw-water samples from the public water supply systems.
