Coastal Change in Alaska

Alaska's north coast has been home to indigenous communities for centuries. Changing coastlines threaten important infrastructure and historic sites that support indigenous communities. Changing coastlines also can potentially reduce habitat for Arctic wildlife, such as polar bears, shorebirds, and walruses. Oil- and gas-related development sites and U.S. Department of Defense installations

Freeport McMoRan-Safford Mine Groundwater Monitoring

In December of 2007, Freeport-McMoRan Safford Inc. (FMSI) (formerly Phelps Dodge Safford, Inc.) began production at the Safford Mine in southeastern Arizona, about 8 miles north of the town of Safford in Graham County. The long-term role of the USGS at the Safford Mine is to help ensure that the effects of mine-related pumpage on the regional aquifer are known and quantified.

Changes in Gravity used to Quantify Groundwater-Storage Change in the Tucson AMA

The Tucson Active Management Area (AMA) is a semi-arid region in southern Arizona. Historically, groundwater pumping in the Tucson AMA exceeded recharge for many decades. Gravity-based methods developed by the USGS can be used to directly measure groundwater-storage changes, providing an estimate of total storage change that does not rely on uncertain estimates of inflows and outflows.
