Warming air temperature is predicted to change water temperature and water column mixing in Oregon’s Crater Lake over the next several decades, potentially impacting the clarity and health of the iconic lake, according to a U.S. Geological Survey report released today.
Past fireworks displays are the probable cause of elevated concentrations of a contaminant called perchlorate in groundwater and surface water within Mount Rushmore National Memorial, according to a recent U.S. Geological Survey report.
Alternative Flows Might Mitigate Negative Impacts
A recent scientific study shows new, important information about how groundwater cannot only contribute nutrients such as nitrogen to lakes, but can also carry it away. Nitrogen is an important nutrient but harmful when over-supplied. The fate and transport of nitrogen are critically important issues for human and aquatic ecosystem health.
South Dakota-based scientists from the U.S. Geological Survey are helping to restore a depleted aquifer and build in-country expertise for managing groundwater in the Ararat Basin of Armenia.
