How machine learning can help regulators

How to locate potentially polluting animal farms has long been a problem for environmental regulators. Now, Stanford scholars show how a map-reading algorithm could help regulators identify facilities more efficiently than ...

Nanoporous material nets contaminant from water

Barely visible material that looks like tiny grains of sand may hold the key to removing an invisible health threat that has contaminated water supplies across the country. Researchers at Pacific Northwest National Laboratory ...

New process to rinse heavy metals from soils

When poisonous heavy metals like lead and cadmium escape from factories or mines, they can pollute the nearby soil. With no easy ways to remove these contaminants, fields must be cordoned off to prevent these toxins from ...

Defects help nanomaterial soak up more pollutant in less time

Cleaning pollutants from water with a defective filter sounds like a non-starter, but a recent study by chemical engineers at Rice University found that the right-sized defects helped a molecular sieve soak up more perfluorooctanesulfonic ...

Researchers create smartphone system to test for lead in water

The discovery of lead in Flint, Michigan's drinking water drew renewed attention to the health risks posed by the metal. Now researchers at the University of Houston have created an inexpensive system using a smartphone and ...

United States Environmental Protection Agency

The U.S. Environmental Protection Agency (EPA or sometimes USEPA) is an agency of the federal government of the United States charged to regulate chemicals and protect human health by safeguarding the natural environment: air, water, and land. The EPA was proposed by President Richard Nixon and began operation on December 2, 1970, when its establishment was passed by Congress, and signed into law by President Nixon, and has since been chiefly responsible for the environmental policy of the United States. It is led by its Administrator, who is appointed by the President of the United States. The EPA is not a Cabinet agency, but the Administrator is normally given cabinet rank. Lisa P. Jackson is the current Administrator. The agency has approximately 18,000 full-time employees.
