Which California communities are more likely to vote down hydraulic fracturing? Are efforts to make safe, affordable drinking water more accessible working? These are among the questions University of California scientists are trying to answer with six new research projects funded by the UC Agriculture and Natural Resources' California Institute for Water Resources.
High-volume hydraulic fracturing, or fracking, a form of natural gas and oil extraction, is water-intensive and could exacerbate water stress. Gwen Arnold, professor in the Department of Environmental Science and Policy at UC Davis, is examining efforts to locally restrict high-volume hydraulic fracturing.
“There's a lot of concern over water pollution and water use in communities,” said Doug Parker, UC ANR California Institute for Water Resources director. “We're looking at the characteristics of communities that have voted on measures to restrict the practice of fracking, both where the measures have failed and where they've passed.”
Parker expects that people on either side of the issue will be able to use the study's finding to better understand differing viewpoints. Decision-makers who may be contemplating policy action on fracking also will benefit from seeing the range of relevant policies passed by other jurisdictions and the conditions that appear to favor or discourage adoption of the policies.
Another research project is assessing the Integrated Regional Water Management approach to address the lack of safe and affordable water in disadvantaged communities throughout the state. In 2011, the California Department of Water Resources funded seven pilot projects to develop models for improving water supplies for these communities.
“We want to take a look at how well Integrated Regional Water Management worked, whether it is meeting the needs of providing safe, affordable drinking water,” Parker said.
Jonathan London, professor in the Department of Human Ecology and director of the Center for Regional Change at UC Davis, and Carolina Balazs, UC presidential postdoctoral research fellow at UC Davis, are evaluating the impact of those efforts in Inyo-Mono counties, Santa Cruz, Los Angeles County, Kings Basin, North Coast, Imperial Valley and Coachella Valley.
UC scientists also received funding for the following projects:
- Roya Bahreini, professor in the Department of Environmental Sciences at UC Riverside, is looking at the relationship between water management and air quality in the Salton Sea region of Southern California, where low water levels are leading to increased dust from the dry lakebed.
- Igor Lacan, UC ANR Cooperative Extension advisor in San Mateo-San Francisco counties, is investigating the performance of trees used in streetside stormwater management facilities, which are increasingly common in cities across California as communities look for ways to increase groundwater infiltration.
- Bruce Linquist, UC ANR Cooperative Extension specialist in the Department of Plant Sciences UC Davis, is quantifying methylmercury loads from rice fields to determine whether they may be of concern.
- Clarissa Nobile, professor in the School of Natural Sciences at UC Merced, is using a high-tech metagenomic approach to research a potential problem for groundwater wells across the state: biofouling, which has the potential to be a costly challenge.
