DALLAS – (December 23, 2016) The U.S. Environmental Protection Agency (EPA), the Texas Commission on Environmental Quality (TCEQ) and Department of State Health Services (DSHS) completed review of sample results following reports of possibly related symptoms from prohibited water use by people living in Corpus Christi to assess current water quality.
None of the ten drinking water samples collected from specific locations within the City of Corpus Christi water supply system tested positive for the presence of Indulin AA-86 in drinking water at method detection levels of 0.05 mg/l for LCMS and 0.26-0.27 mg/l for GCMS. The EPA and TCEQ toxicologists established a health-based action level of 2.6 mg/l in drinking water. Continue reading “Drinking water confirmation sample results”→
Getting clean water to communities in parched areas of the planet remains an ongoing challenge. Recent developments that harvest water from air have been proposed as a solution. However, the technology to do so consumes a lot of energy. But based on new modeling results, scientists now report in ACS’ journal Environmental Science & Technology that a new system design would require less energy and produce high-quality water.
The atmosphere around us contains water vapor in amounts comparable to all the surface and underground liquid freshwater on the planet, according to an International Organization for Dew Utilization study published in 2000. However, current machines that collect water from this airy reservoir have major limitations.
For example, one method uses electrical refrigeration to cool the air and condense the vapor, but that consumes 40 to 90 percent of the total system’s energy requirements.
Scientists from the Technion (Israel) compared this strategy to their new design that uses a liquid desiccant to first separate the vapor from air and then cool only the vapor.
Their calculations show that this approach would result in 20 to 65 percent energy savings over the standard system, depending on where the technology is applied and the sites’ climate conditions.
ALEXANDRIA, Va., August 5, 2015 – The Value of Water Coalition and the Water Environment Federation (WEF) have released and are promoting the use of a new public awareness campaign and toolkit, “What’s the Value of Water?” As one of the original partners, WEF has been collaboratively working with the Value of Water Coalition, WEF members, volunteers, and leaders to help raise awareness about the value and importance of water. The new toolkit is an important part of this effort and is available at no cost to anyone interested in educating the public about the essential need to invest in our water infrastructure and water resources.
Assessment shows hydraulic fracturing activities have not led to widespread, systemic impacts to drinking water resources and identifies important vulnerabilities to drinking water resources.
WASHINGTON, June 4, 2915 – The Environmental Protection Agency (EPA) is releasing a draft assessment today on the potential impacts of hydraulic fracturing activities on drinking water resources in the United States. The assessment, done at the request of Congress, shows that while hydraulic fracturing activities in the U.S. are carried out in a way that have not led to widespread, systemic impacts on drinking water resources, there are potential vulnerabilities in the water lifecycle that could impact drinking water. The assessment follows the water used for hydraulic fracturing from water acquisition, chemical mixing at the well pad site, well injection of fracking fluids, the collection of hydraulic fracturing wastewater (including flowback and produced water), and wastewater treatment and disposal [http://www2.epa.gov/hfstudy/hydraulic-fracturing-water-cycle].
BOSTON, Mass., May 20, 2015 – After four years of drought and mixed results from efforts to roll back water use, the scale of California’s water crisis has brought the state to the brink of massive investments in water supply, including desalination, water diversion, and water treatment. One solution certain to receive significant new funding in the years ahead, according to a new study from Bluefield Research, is wastewater re-use.
Today only one-third of California’s wastewater treatment plants provide treated water that is re-used for industrial, agricultural or municipal purposes. According to Bluefield, wastewater re-use in the state stands to double just based on projects already in the pipeline, most of which were conceived before the current crisis.
Las Vegas, Nevada, April 26, 2015 – Sweden-based Bluewater, the leading name in premium residential water purifiers, today announced the global launch of three new water purifiers offering a harmonized balance of design personality, performance and price that give users a choice of devices enhancing health, wellness and lifestyle needs. Bluewater opted to launch its high-performance, Scandinavian-designed new models at the WQA Aquatech USA 2015 water industry trade show in Las Vegas, Nevada, running 22 – 24 April.
Water quality and environmental issues can have tremendous impacts on soybean farming. With so many issues involving the intersection of agriculture, public policy, and environmental concerns these days, it’s absolutely essential that we all gain a better understanding of our common ground.
That was an important theme for us during a panel discussion at the American Soybean Association’s Leadership College on Jan. 7 in St. Louis. With me on the panel was Roger Wolf, the Iowa Soybean Association’s director of environmental programs and services; and Adam Ward, executive director of the Ohio Soybean Association.
