Watershed Stewardship in Minnesota: Protecting Valley Creek in the Land of 10,000 Lakes
The Saint Croix Watershed is home to dozens of lakes, rivers, and streams that host an abundance of aquatic life from its tributaries. Valley Creek, a tributary of the St. Croix River, is a designated trout stream and while it is a pristine waterway, ongoing monitoring and stewardship establish a baseline of conditions and protect the creek. Don Wendel and Dllona Clendenen, Minnesota Master Naturalists, Liberal Arts majors, and retired college teachers, are two members of the wetlands research team based out of the Science Museum of Minnesota’s St. Croix Watershed Research Station that monitors Valley Creek throughout the year.
New EcoVerde bacteria-based filter removes odor from wastewater
U.S.-based company EcoVerde created a new filtering system that uses bacteria to get rid of odors and other undesirables in wastewater, according to a release from Investigación y Desarrollo. The process funnels air from over the sewage water and sends to the “bioscrubber EG” system. The air is then removed and the odor-causing organisms are sent to the filter where waiting bacteria destroy them. The filtration system employs a combination of autotrophic and heterotrophic bacteria to remove a variety of pollutants using oxidation. The system can handle highly polluted sewage as this means more food for the bacteria without raising costs. EcoVerde has extended its technology to Mexico to assist districts near sewage plants.
Hach DR900 handheld colorimeter is simple, versatile and field-ready
For wastewater professionals and scientists studying changes in water chemistry, the Hach DR900 is a handheld colorimeter with streamlined features, rugged construction and value that are hard to match. Commonly used in small lab settings and mobile applications, the Hach DR900 beats similar devices on the market by making things a little more intuitive. “Many competitive products require a method number to be entered into the instrument before each test,” said Thomas Siller, product manager at Hach Company. “The DR900 has all of the methods pre-programmed into the instrument.” So after turning the DR900 on to take a measurement, users can simply scroll down the method list and select a parameter.
For Living Waters for the World, the mission is clean drinking water
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.
