What is the difference between PFOS and PFAS?
Q: What’s the difference between PFOS and PFAS?
A: PFAS is a broad term that refers to a large group of man-made chemicals that contain fluorine atoms. This group includes thousands of different compounds and are highly resistant to degradation.

Ammonia or Ammonium? What’s the difference?
Ammonia or ammonium? What’s the difference? In water, ammonia (NH3) and ammonium (NH4+) exist together in an equilibrium that depends on pH and temperature. As the temperature or pH rise, ammonia (NH3) becomes more abundant. This is important because ammonia is more toxic than ammonium.

Outstanding in the Field Episode 7 - Science in the Swamp
In this episode of Outstanding in the Field, we take you to the swamps and coastal wetlands of Louisiana, the land of bayous and beignets and a state with one of the most dynamic coastlines in the United States. The wetlands that make up the Louisiana coast are vast and help protect important cultural and natural resources.
