Streamflow Depletion by Wells
February 15, 2013 |
"Groundwater and surface-water systems are connected, and groundwater discharge is often a substantial component of the total flow of a stream. Groundwater pumping reduces the amount of groundwater that flows to streams and, in some cases, can draw streamflow into the underlying groundwater system." The United States Geological Survey has published: Streamflow Depletion by Wells—Understanding and Managing the Effects of Groundwater Pumping on Streamflow. Quote from the USGS press release.

An article on The Oklahoman website explains the growing importance of railroads to the energy sector. More crude oil and frac sand are being shipped by rail today than ever before.
Old Nitrate and Stream Water Quality
June 16, 2013 | USGS
"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 — whether the change is initiation, adjustment, or cessation — may take decades to be fully observed in streams." Quoted from the USGS press release.
