Scientists, community groups, and the Clean Water Act are behind Washington, D.C.’s massive project to reduce combined sewer overflows by 96%.
A study of 369 lakes across the Midwest finds that many of them, especially those close to agriculture, have high concentrations of harmful algal bloom-causing cyanobacteria.
By reviewing 44 studies, researchers make a scientific case for regulating agricultural pollution of streams and rivers by implementing conservation practices, including riparian buffer zones.
Poor infrastructure is responsible for tens of thousands of pharmaceutical doses that flow through Baltimore’s streams each year.
Abandoned hardrock mines and climate change cause metals and other elements to leach into streams. They also put rare earth elements into the water, a new study finds.
As floods increase in frequency and intensity, chemicals buried in river sediments become “ticking time bombs” waiting to activate.
Agriculture is a key contributor to the algae mats that plague Lake Erie. With so many fertilizers entering the lake, could sediment from the lake floor be used to grow crops instead?
Harder to analyze and quantify, diffuse pollution is often overlooked when it comes to water quality assessments.
Sediments from a lake in Switzerland reveal that ancient Romans triggered dead zones caused by the runoff of nutrients. Sound familiar?
