An aquifer is a layer of porous substrate that contains and transmits groundwater. When water can flow directly between the surface and the saturated zone of an aquifer, the aquifer is unconfined. The deeper parts of unconfined aquifers are usually more saturated since gravity causes water to flow downward.

Groundwater Recharge Options

A Pathway to Water
There are several ways to deal with declining aquifers; some of these are already being practiced to varying degrees throughout the United States. Such measures include increasing water efficiency, which can slow the drawdown of aquifers by using available water more sparingly. Another method coming into wider

Study Explores Groundwater, Geothermal Energy in Drought States

PORTLAND, Ore. — A new study now underway by the U.S. Geological Survey is exploring the groundwater resources and geothermal energy potential in drought-stricken areas of eastern Oregon and nearby parts of California, Idaho and Nevada. Volcanoes are associated with vast amounts of geothermal energy and lava-flows form many of the Pacific

Stormwater Takes Its Role in Aquifer Recharge

Stormwater Takes Its Role in Aquifer Recharge

It’s not always clear where water can be found or how much of it is available, and in the face of dramatic climate change, it’s even more uncertain how much quality water will be available in the future. Due to changes in climate, development pressure, and rising consumption, rivers and

Senior Water Rights Curtailed in California

Senior Water Rights Curtailed in California

SACRAMENTO, June 12, 2015 — With drought conditions continuing into the summer months, the State Water Resources Control Board (State Water Board) announced today that there is insufficient water available for senior water right holders with a priority date of 1903 or later in the San Joaquin and Sacramento watersheds and

California Curtails Sacramento River, Delta Junior Water Rights

SACRAMENTO, May 1, 2015 – With California’s extreme drought resulting in insufficient water to serve all water-right holders, the State Water Resources Control Board (State Water Board) announced today that junior water-right holders in the Sacramento River watershed and Delta are receiving curtailment notices. The notices advise the recipients to

Greening the Urban Water Supply

Greening the Urban Water Supply

According to the Natural Resources Defense Council (NRDC), cities and suburbs are among the largest sources of water pollution in many parts of the US. As Lawrence Levine wrote in his NRDC Issue Brief, “Waste Less, Pollute Less: Using Urban Water Conservation to Advance Clean Water Act Compliance,” these cities
