Groundwater in Virginia is a greater contributor to streamflow than calculated by the most commonly used technique, according to recent USGS research. For decades, hydrologists have used only the changing water levels and flow rates, a graphical hydrograph separation or GHS method, in streams to try to estimate the base-flow component. However, many individual studies during

Groundwater provides drinking water for millions of Americans and is the primary source of water to irrigate cropland in many of the nations most productive agricultural settings. Although the benefits of groundwater development are many, groundwater pumping can reduce the flow of water in connected streams and rivers—a process called streamflow depletion by wells. The USGS

As recovery efforts for those impacted by Hurricane Sandy continue, U.S. Geological Survey crews are sampling water for nutrients, sediment, and pesticides to document water quality in areas affected by the hurricane. This sampling effort is part of the federal government’s broad efforts to ensure public health and to support the state, tribal, and local response

Much of the border Canada and the United States share is water. The Great Lakes, the world’s largest freshwater resource, and the St. Lawrence Seaway, as well as thousands of rivers and streams traverse this 8,000-kilometre boundary. Until recently, there had been no consistent data on these water bodies to help prevent and resolve transboundary

The Open Geospatial Consortium (OGC®) has adopted the OGC WaterML 2.0 Part 1: Time Series Encoding Standard as an official OGC standard. OGC WaterML 2.0 is an important new XML-based international standard for encoding and exchanging data describing the state and location of water resources, both above and below the ground surface.

The Mississippi River/Gulf of Mexico Watershed Nutrient (Hypoxia) Task Force announced today that it is launching two new efforts to monitor reductions in nutrients – nitrogen and phosphorus – throughout the watershed. The joint federal, state and tribal task force, chaired by the U.S. Environmental Protection Agency (EPA) and the State of Iowa, has established

A powerful new flood preparedness tool that will help emergency managers protect lives and property in the flood-prone Sweetwater Creek area was unveiled in a ceremony today on the banks of the creek at Austell’s Legion Regional Park. Developed by scientists from the U.S. Geological Survey’s Georgia Water Science Center, the interactive web-based tool, called

EPA’s draft 2012 Strategy adresses climate change impacts on water resources and EPA’s water programs. Climate change alters the water cycle and could affect the implementation of EPA’s programs. EPA and our state, tribal, local and federal partners must review and adapt the practices that have been developed over the past 40 years since passage of the Clean Water Act,
