Nitrate contamination of water is a worldwide environmental problem. Recent studies have
demonstrated that the nitrogen (N) and oxygen (O) isotopes of nitrate (NO 3−) can be used …

Groundwater recharged by meteoric water supports human life by providing two billion
people with drinking water and by supplying 40% of cropland irrigation. While annual …

Remediation of nitrate pollution of Earth's rivers and aquifers is hampered by cumulative
biogeochemical processes and nitrogen sources. Isotopes (δ 15N, δ 18O) help unravel …

Microbial Fe (III) reduction is a significant driving force for the biogeochemical cycles of C, O,
P, S, N, and dominates the natural bio-purification of contaminants in groundwater (eg …

Increased nitrate concentration is one of the main groundwater quality problems today that
needs to be measured and monitored. Water quality testing and monitoring are time …

This study assessed the effects that season and tillage practices have on the diversity of
nitrous oxide producing bacteria (nitrifiers and denitrifiers) and to relate this to measured …

Cover cropping is a practice with potential to reduce post-harvest surplus of soil nitrate (NO
3-), a mobile form of nitrogen naturally susceptible to losses. Increased soil NO 3-leaching …

Intensification of potato farming has contaminated groundwater with nitrate in many cases in
Prince Edward Island, Canada, which raises concerns for drinking water quality and …

Nitrate (N-NO 3) concentration in groundwater, the sole source of potable water in Prince
Edward Island (PEI, Canada), currently exceeds the 10 mg L-1 (N-NO 3) health threshold for …

Although agricultural lands are generally assumed to correlate negatively with groundwater
quality, the intricate relationship between general land cover and contaminant …
