The Great Lakes watershed is the largest system of fresh surface water in the world and is a source of abundant natural resources. However, urban and industrial development along the shoreline has degraded water quality, posing threats to wildlife and human health. Restoration of Great Lakes ecosystems is now a priority among federal, state, and

A new U.S. Geological Survey study documents that the Nation’s aquifers are being drawn down at an accelerating rate. Groundwater Depletion in the United States (1900-2008) comprehensively evaluates long-term cumulative depletion volumes in 40 separate aquifers (distinct underground water storage areas) in the United States, bringing together reliable information from previous references and from new

USGS hydrologic researchers have found that the movement of nitrate through groundwater to streams can take decades to occur. This long lag time means that changes in the use of nitrogen-based fertilizer (the typical source of nitrate) — whether the change is initiation, adjustment, or cessation — may take decades to be fully observed in
