The nitrogen (N) cycle involves a set of N compounds transformed by plants and microbes.
Some of these N compounds, such as nitrous oxide (N 2 O) or nitrate (NO 3−), are …

Biogeochemical processes controlling nitrate attenuation in aquifers are critically reviewed.
An understanding of the fate of nitrate in groundwater is vital for managing risks associated …

Denitrification is a critical process regulating the removal of bioavailable nitrogen (N) from
natural and human‐altered systems. While it has been extensively studied in terrestrial …

Nitrate (NO3−) concentrations in public water supplies have risen above acceptable levels
in many areas of the world, largely as a result of overuse of fertilizers and contamination by …

Denitrification is increasingly recognized for its ability to eliminate or reduce nitrate
concentrations in groundwater. With this awareness comes a desire to predict the rate and …

Denitrification, the reduction of the nitrogen (N) oxides, nitrate (NO3−) and nitrite (NO2−), to
the gases nitric oxide (NO), nitrous oxide (N2O), and dinitrogen (N2), is important to primary …

Pollution of the hydrosphere and atmosphere by compounds of nitrogen is a serious
problem. This paper reviews the manner in which studies of natural abundance 15 N/14 N …

This study explores the use of multiple isotopic tracers to evaluate the processes involved in
nitrate attenuation in ground water. δ15N and δ18O are used to provide information about …

The biological clogging of natural porous media, often in conjunction with physical or
chemical clogging, is encountered under a wide range of conditions. Wastewater disposal …

Reduction/oxidation (redox) conditions in 15 principal aquifer (PA) systems of the United
States, and their impact on several water quality issues, were assessed from a large data …
