Global Patterns of Nitrate Storage in the Unsaturated Zone

Global Patterns of Nitrate Storage in the Unsaturated Zone

The British Geological Survey has released a global-scale quantification of nitrate stored in the vadose zone between 1900 and 2000. One of the study's conclusions is that areas identified as having high nitrate stores in the unsaturated zone are likely to exhibit delayed improvements in surface water and groundwater quality following reductions in nitrate input.

National Ground Water Association Releases Groundwater Modeling White Papers

The National Ground Water Association recently released a series of white papers intended to advance the science of groundwater modeling. These papers address groundwater modeling topics such as uncertainty and model use by decision makers, among other timely topics for practitioners and consumers of groundwater models.
