Californias agricultural regions gear up to actively manage groundwater use and protection
Published in California Agriculture
New regulations are emerging in response to historic groundwater depletion and widespread groundwater quality degradation in California. They aim at long-term preservation of groundwater resources for use in agriculture, in urban areas and for the support of ecosystems in streams dependent on groundwater. The regulations are driving a historic shif...
Economic Feasibility of Irrigated Agricultural Land Use Buffers to Reduce Groundwater Nitrate in Rural Drinking Water So...
Published in Hydro Nepal Journal of Water Energy and Environment
Agricultural irrigation leachate is often the largest source for aquifer recharge in semi-arid groundwater basins, but contamination from fertilizers and other agro-chemicals may degrade the quality of groundwater. Affected communities are frequently economically disadvantaged, and water supply alternatives may be too costly. This study aimed to de...
The role of perched aquifers in hydrological connectivity and biogeochemical processes in vernal pool landscapes, Centra...
Published in Hydrological Processes
Relatively little is known about the role of perched aquifers in hydrological, biogeochemical, and biological processes of vernal pool landscapes. The objectives of this study are to introduce a perched aquifer concept for vernal pool formation and maintenance and to examine the resulting hydrological and biogeochemical phenomena in a representativ...

A team of California researchers propose a general outline to guide local agencies in crafting Groundwater Sustainability Plans under the California Sustainable Groundwater Management Act of 2014
Creating Effective Groundwater Sustainability Plans
...
California is entering a new era in how it manages its largest source of water storage — groundwater. Initial efforts implementing the state’s new Sustainable Groundwater Management Act must focus on getting local and state agencies organized and able to communicate with each other. Having common expectations for the contents of the law’s required ...

Assessing Potential Impacts of Livestock Management on Groundwater
This supplemental paper provides a brief review of the potential for groundwater pollution from animal feeding operations (AFOs). Management activities that address surface water quality may reduce nutrient loads, but they may also lead to a deterioration of groundwater quality as well as additional methane emissions. Groundwater pollutants may eve...
