Possible Geological-Geochemical Sources of Ammonium in Groundwater: Preliminary Results [PDF]

, 2003
Ammonium has been detected in water wells in relatively large (>2 mg/L) concentrations in east-central Illinois and in central Iowa. Ammonium can interfere with drinking-water disinfection, and can be converted into nitrate and nitrite.

Combining seepage meters and amphibious electric resistivity tomography to investigate pathways of submarine groundwater discharge

Submarine groundwater discharge (SGD) plays a pivotal role in coastal biogeochemistry, yet it is still challenging to accurately quantify water and solute fluxes driven by this process due to its complex hydrogeological dynamic. This work aims to improve

The use of numerical groundwater model to improve effectiveness of subsurface drainage system in irrigated field

, 2009
The research demonstrates that Three-Dimensional Variable-Density Groundwater Flowmodels such as the SEAWAT model can be effectively used for design of subsurfacedrainage systems for controlling salt concentration in the root zone on salt ...
