PFOS & PFOA: Air Force researchers develop new weapon to cleanse water

Air Force researchers develop new weapon to cleanse water

As the state gears up for wider testing of public water systems for potentially harmful chemicals, civilian researchers at Wright-Patterson Air Force Base believe they may be closing in on a new weapon in the battle against toxic water.

Researchers at the base recently completed a two-week field demonstration of a plasma technology they say destroys potentially harmful chemicals perfluorooctane sulfonate and perfluorooctanoic acid — also known as “PFOS” and … [more…]

Adjusting the water flow rate in a river can prevent invasive species from moving upstream and expanding their range. An applied mathematician at UT has developed a partial differential equation model to find the desired flow rate to reduce invasive populations.

The model is detailed in a new paper by Suzanne Lenhart, Chancellor’s Professor and James R. Cox Professor of Mathematics, published in Mathematics.
