In Tabasco, Mexico, water is left undrinkable by mineral deposits in soil and a coastal aquifer that runs beneath the Yucatan Peninsula. Many communities can’t treat it and depend on trucks to bring in drinking water.
But for one small community there, a mission group helped reduce its dependence on outside water by setting up and donating a custom water filtration system. A church houses the system and gives treated water to those who can’t afford it at no cost. The water is otherwise sold commercially at half the price offered by other bottlers.
Living Waters for the World is a mission project of the Presbyterian Church - USA and is no stranger to water treatment projects.Read More
Water quality issues are shifting in the United States’ rivers in big ways.
Those changes are driven, in part, by the way the land in a watershed is used and they’re big enough that researchers may need to change the way they think about water quality in the American rivers.
“What was striking to us was how perceptions of water quality issues from several decades ago may need to be updated,” said Edward Stets, a U S Geological Survey research ecologist, in an email response to questions from Environmental Monitor.
New research by Stets published in Environmental Science &; Technology in March highlights these shifting water quality issues.Read More
The start of Duke University’s oceanographic mooring line doesn’t begin at the surface of the ocean, but 500 meters beneath it. Floating at the top of the mooring system is a 64-inch syntactic sphere with 2,500 Lbs of buoyancy. It serves a duo of roles as both a floatation device and housing for two high-end acoustic monitoring systems.
Next comes 75 meters of chains and wires before coming to two ocean current profilers, one pointing up and the other pointing down. Next to that equipment are two instruments that measure temperature and salinity.
Next comes several hundred more meters of wire before arriving at several glass balls, more floatation orbs.Read More
