Will natural gas dim solar’s shine?

by Ensia  (Mar. 9, 2015)

As natural gas booms, renewable energy proponents ponder whether it will serve as a bridge or roadblock to photovoltaic power On the outskirts of downtown St. Paul, Minn., Xcel Energy’s High Bridge Generating Station offers an iconic view of the current state of electrical generation in the United ...

Groundwater management in China

by IWA Publishing  (Feb. 6, 2015)

After introducing groundwater development and other issues, the paper analyzes China's groundwater management system and its problems, and provides suggestions for improving the system. Increasing water demand since the 1970s has resulted in severe groundwater overdraft, water level decline and water quality degradation in China, but the ...

Risk of diarrhoea from shallow groundwater contaminated with enteropathogens in the Kathmandu Valley, Nepal

by IWA Publishing  (Feb. 27, 2015)

Shallow groundwater is the main water source among many alternatives in the Kathmandu Valley, Nepal, which has a rapidly growing population and intermittent piped water supply. Although human pathogens are detected in groundwater, its health effects are unclear. We estimated risk of diarrhoea from shallow groundwater use using quantitative ...

Numerical simulation of drainage scenarios for lowering groundwater rise due to construction of a new barrage on the Nile River

by Inderscience Publishers  (Mar. 2, 2015)

The government of Egypt constructed a New Naga Hammadi Barrage (NNHB) 3.6 km downstream of the Old Naga Hammadi Barrage (ONHB). Upon construction, the water level raised by about 0.5 and 4 m upstream and within the river reach between ONHB and NNHB respectively. In this paper, a two–layer groundwater model was built using MicroFEM to study the ...

Well water win-win

by Ensia  (Oct. 22, 2014)

Solve two problems with one filter? That’s what Drinkwell aims to do. Begun through a collaboration between researchers at Lehigh University and the Bengal Engineering and Science University, the Boston-based social venture ...

Groundwater arsenic in Chimaltenango, Guatemala

by IWA Publishing  (Sep. 25, 2014)

In the Municipality of Chimaltenango, Guatemala, we sampled groundwater for total inorganic arsenic. In total, 42 samples were collected from 27 (43.5%) of the 62 wells in the municipality, with sites chosen to achieve spatial representation throughout the municipality. Samples were collected from household faucets used for drinking ...

Who Owns Groundwater?

by Ensia  (Aug. 28, 2014)

California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, ...

Arsenic in private drinking water wells: an assessment of jurisdictional regulations and guidelines for risk remediation in North America

by IWA Publishing  (Sep. 25, 2014)

Arsenic is a known carcinogen found globally in groundwater supplies due to natural geological occurrence. Levels exceeding the internationally recognized safe drinking water standard of 10 μg/L have been found in private drinking water supplies in many parts of Canada and the United States. Emerging epidemiological evidence confirms ...

Road Over Sensitive Groundwater Areas - Case Study

by NAUE GmbH & Co.KG  (Aug. 8, 2014)

When constructing or extending new roads, the responsible designers and contractors are increasingly faced with the task of preventing soil contamination. Therefore, measures for the protection of the groundwater are necessary in more and more cases. The corresponding requirements and specifications for such measurements are regulated in the ...

Potential impact of heterogeneity on groundwater age

by IWA Publishing  (Jun. 12, 2014)

Groundwater age is an important water property used as an indicator of groundwater quality. There have been no sufficient data and measurements underground, and that problem has been mitigated by using direct simulation of groundwater age. This paper has been motivated by the work of Daniel J. Goode, defining a rather different approach. A ...
