Freshwater Environmental Quality Parameters

By tweaking the chemistry of rivers and oceans, humans could remove billions of tons of carbon dioxide from the air. But huge challenges loom.

A breakdown of the sources of many air pollutants that damage our health and ecosystems.

A Florida State University scientist has helped uncover through a multidecadal study how changing water chemistry in Arctic rivers could impact the entire planet.

Beneath the surface of rivers lurks a hazard that isn't well understood—but could wreak havoc on people and communities near the water.

Rivers flow across many kinds of terrain, interacting with soil, rocks, microbes, and roots. River water therefore carries signatures of everything it interacts with, and its chemistry reflects the response of the critical zone—the region of the planet stretching from the tops of trees to the bottom of groundwater—to changing climate. River chemistry is likely to change with a warming climate, yet most…
