USGS, in cooperation with the Albuquerque Bernalillo County Water Utility Authority, began repeat microgravity measurements in 2015 to monitor aquifer-storage changes in the Albuquerque basin.
Repeat microgravity data are collected across a network of 31 relative- and absolute-gravity stations. Many of these are collocated with monitoring wells, including nested piezometers, that provide useful information about head changes at different depths in the aquifer. Surveys are carried out three times per year, and include GPS observations to monitor for changes in elevation (which is also monitored using extensometers).
