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…]

Solar and wind energy preserve groundwater for drought, agriculture

Solar and wind energy preserve groundwater for drought, agriculture

Using drought-prone California as a case study, a research team shows that increased solar and wind energy can reduce the reliance on hydropower, especially during drought. Credit: Egan Jimenez, Princeton University

Solar and wind farms are popping up around the country to lower carbon emissions, and these renewables also have another important effect: keeping more water in the ground.

A new Princeton University-led study in Nature Communications is among the … [more…]

Well water users warned, Air Force Academy finds toxic level of firefighting chemical

Well water users warned after Air Force Academy finds toxic level of firefighting chemical

Air Force Academy firefighters training a quarter century ago released a torrent of toxic perfluorinated chemicals that seeped into groundwater and flowed into Monument Creek, a 15,000-page Air Force report released Friday shows.

A series of tests by Air Force researchers showed groundwater had 1,000 times the level of perfluorinated compounds considered safe by state and federal regulators. Records on the training that used firefighting foam loaded with the chemicals … [more…]

Alfalfa Project Targets Saving Over 300 Billion Gallons of Water Annually

A history of drought refugees in America.

San Francisco, CA (PRWEB) – It was 83 years ago this week, when 23 car and truck-loads of migrant families were reported to have crossed the California-Arizona border in a single day. They were among tens of thousands of poverty-stricken families who found themselves without water in 1936, as drought and erosion in the Southern Plains swept through about 100 million acres of … [more…]

Dwindling groundwater, ever-deeper wells could spell trouble for Arizonans

Dwindling groundwater, ever-deeper wells could spell trouble for Arizonans

Araceli Silva moved to her colonia near Yuma decades ago 27 years ago. She’s struggled with her wells, which have run dry more than once. A new study finds that wells that bring groundwater to the surface are being dug deeper to tap dwindling aquifers. (Photo by Maria Esquinca/News21)

PHOENIX – Wells are drying up because groundwater is being depleted, and that affects food production and access to drinking water. … [more…]
