Economic Feasibility of Irrigated Agricultural Land Use Buffers to Reduce Groundwater Nitrate in Rural Drinking Water Sources

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...

Agriculture’s Contribution to Nitrate Contamination of Californian Groundwater (1945–2005)

Nitrogen (N) use in intensive agriculture can degrade groundwater resources. However, considerable time lags between groundwater recharge and extraction complicate source attribution and remedial responses. We construct a historic N mass balance of two agricultural regions of California to...

Using high resolution subsurface modeling in managed aquifer recharge

The elimination of baseflow due to declining groundwater levels has compromised many ecological functions of the Cosumnes River. Numerical modeling has shown that floodplain reconnection can be a viable method to increase groundwater recharge - mitigating overdraft and helping re-establish...
