Stanford Study Probes Psychological Resistance to Recycled Water

Stanford researchers have found that Californians’ views on recycled water depend heavily on how that water is eventually used.

The study, which appeared in the August 2017 issue of Water and Environment Journal, revealed that psychological resistance to using treated effluent can be reduced, to some extent, by explaining the treatment process to people and informing them of an existing program in Orange County.

Public Receptiveness of Vertical Axis Wind Turbines

Most of the scholarly focus to date has been on large horizontal axis rather than vertical axis wind turbines. It may be possible to improve the efficiency of vertical axis wind technology by deploying turbines in clusters. There might also be advantages to deploying vertical axis turbines at a smaller scale in urban or suburban areas and in places where the risk of bird damage is highest.

Dry Groundwater Wells in the Western United States

Debra Perrone and co-author Scott Jasechko validate concerns of many California homeowners in areas like Ceres and Denair that domestic wells are more susceptible to drying. The researchers analyzed millions of well depth records in 17 western states and found that during 2013 to 2015, about 1 in 30 wells were dry. Further, dry wells tended to be concentrated in rural communities. In some rural areas, the research suggests that as many as 1 in 5 wells were dry at certain times.

The New Western Fugitives: Ozone Ingredients from Oil and Gas

Most people think of dangerous levels of ozone gas occurring in traffic congested cities like Los Angeles, so it’s a surprise to find high concentrations of it in pristine areas of the American West. But it’s happening. Two basins that lie along the Green River in the intermountain West have some of the worst ozone pollution in the nation. Reported and written by John McChesney.
