A new study links geological factors such as faulting and geothermal activity to an elevated risk of arsenic contamination in private wells across the Great Basin.
Tracking Heavy Metal Accumulation in the Nile Delta
Sediment measurements show that flow alterations and discharges are driving increasing concentrations of multiple heavy metals in the Nile Delta, threatening ecosystems, agriculture, and human health.
Suivie de l’accumulation des métaux lourds dans le Delta du Nil
Les analyses de sédiments montrent que la réutilisation de l’eau non traitée et la construction de barrages entraînent l’augmentation des concentrations de métaux lourds dans le Delta du Nil, menaçant gravement les écosystèmes, l’agriculture et la santé humaine.
U.S. Public Water Supply Is a Local Source of Phosphorus Pollution
Excess phosphorus may reach U.S. rivers, lakes, and groundwater through water main leaks and outdoor water use.
What Happens to Drugs After They Leave Your Body?
It’s hard to predict with certainty how drugs break down once they enter waterways. In a new study, scientists devised a way to do just that.
The Importance of Springs and Why Humanity Needs to Protect Them
A new book explores why springs are critical for humanity and ecosystems, the threats they are facing, and how we can act now to protect and restore them.
Understanding Enhanced Arsenic Pollution in Shallow Lakes
A new study explains why the arsenic that has accumulated in lake bottom sediments is more harmful to the lake ecosystems in shallow lakes.
Wetlands on the Farm: Potent, Nutrient-Capturing Tools in (Relatively) Small Packages
Constructed wetlands can significantly reduce water pollution from tile-drained farms.
The Fate of a Lake After a Dramatic Mining Disaster
Researchers tracked long-term sediment dynamics in Canada’s Quesnel Lake following the 2014 failure of a dam that spilled record-breaking amounts of contaminated mining waste.
The Shapes of Shrimp Farms Affect Their Groundwater Pollution
New findings may help decisionmakers optimize shrimp farm layouts, which could help improve coastal water quality.
