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”

Harvesting water from air with less energy

Liquid-Desiccant Vapor Separation Reduces the Energy Requirements of Atmospheric Moisture Harvesting

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.

San Francisco, December 22, 2015 – The U.S. Environmental Protection Agency announced more than $19 million in funding to Nevada for investments in statewide improvement in local drinking water and wastewater infrastructure and the reduction of water pollution. Nevada’s Clean Water State Revolving Fund (SRF) provides financing for municipal wastewater treatment projects, while the state’s Drinking Water SRF provides financial assistance for drinking water infrastructure improvements.

“This substantial investment at the federal level helps communities develop the infrastructure needed for clean, safe drinking water and proper wastewater treatment,” said Jared Blumenfeld, EPA’s Regional Administrator for the Pacific Southwest. “EPA is committed to protecting the water resources so important to public health and Nevada’s economy.” Continue reading “EPA Announces $19 Million for Drinking Water and Wastewater Infrastructure Projects in Nevada”

Value of Water Coalition Unveils New Education Campaign and Toolkit

EPA Releases Draft Assessment on the Potential Impacts to Drinking Water Resources from Hydraulic Fracturing Activities

Assessment shows hydraulic fracturing activities have not led to widespread, systemic impacts to drinking water resources and identifies important vulnerabilities to drinking water resources.

EPA Releases Draft Assessment on the Potential Impacts to Drinking Water Resources from Hydraulic Fracturing ActivitiesWASHINGTON, 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].

Drought Driving Greater Reliance on Wastewater Reuse In California

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.

Common Ground for Soybean Farming and Clean Water
A speaker reads questions to the audience during the American Soybean Association’s Leadership College panel event.

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.
