    nitrate contamination of groundwater is presented. A recirculating nitrate treatment well system is proposed in which groundwater is drawn into the well, denitrified in the treatment chamber, and returned to the top of the aquifer. Well hydraulics were experimentally examined in a two-dimensional aquifer model, and ambient groundwater. USGS microbiologists and their colleagues have used a two-phase approach to developing remediation strategies for nitrate contamination in ground water. In the field, USGS scientists have been investigating the potential for enhancing denitrification (the reduction of nitrate to nitrogen gas) by injecting sodium formate into the aquifer.

    Keywords—Nitrate Pollution, Occurrences of Nitrate in India, Health effects and prevention. Introduction: Groundwater contamination by nitrate is a global problem and Nitrate is a wide-spread contaminant of ground and surface water worldwide. Nitrate (NO3−) is one of the integral parts in the growth of life and it File Size: KB. The risk of ground-water contamination by nitrate depends both on the nitrogen input to the land surface and the degree to which an aquifer is vulnerable to nitrate leaching and accumulation. Variables describing nitrogen input and aquifer vulnerability were estimated and compiled in a national map (figure 1) using procedures described by.

    ineffective if the primary source of nitrate contamination is agricultural operations. Determining the source of nitrate in an aquifer, however, can be difficult. Nitrate occurs naturally and has a number of anthropogenic sources, including synthetic fertilizers, animal manure, septic systems, and municipal wastewater.

A series of laboratory tests were conducted to evaluate whether denitrification would be a suitable alternative for biorestoration of an aquifer contaminated with JP-4 jet fuel. Microcosms were prepared from both uncontaminated and contaminated aquifer material from the site, in an anaerobic glovebox, amended with nitrate, nutrients, and.

EXECUTIVE SUMMARY A field demonstration project on Nitrate-mediated biorestoration of a fuel-contaminated aquifer was conducted at a U.S. Coast Guard facility in Traverse City, Michigan. Several leaks from an underground storage'facility containing JP-4 jet fuel have resulted in contamination of ground water at the site.

To the author’s knowledge, nitrate enhanced bioremediation has been used at only one other fuel contaminated site in the United States, One factor constraining the use of nitrate bioremediation is that nitrate in groundwater is subject to a drinking water standard.

This research was undertaken to provide a direct comparison through the operation of a pilot project at a JP-4 jet fuel-contaminated aquifer at Eglin AFB, FL. Nitrate can serve as an electron acceptor and results in anaerobic biodegradation of organic compounds via.

A JP-4 fuel-contaminated aquifer that underwent a pilot demonstration of nitrate-enhanced bioremediation was characterized microbially before, during and after treatment.

The most probable number of total denitrifiers, denitrifiers that use JP-4 or JP-4 degradation products, aerobic and anaerobic protozoa, and the number of heterotrophs and JP-4 degrading microorganisms were determined.

Nitrate also can serve as an electron acceptor and is more soluble in water than oxygen. The addition of nitrate to an aquifer results in the anaerobic biodegradation of toluene, ethylbenzene, and xylenes. The benzene component of fuel has been found to biodegrade slower under strictly anaerobic conditions.

In Situ Bioreclamation: Applications and Investigations for Hydrocarbon and Contaminated Site Remediation is a collection of selected papers submitted by participants to the international symposium ""In Situ and On-Site Bioreclamation"", held in San Diego, California in March Bioremediation is a process used to treat contaminated media, including water, soil and subsurface material, by altering environmental conditions to stimulate growth of microorganisms and degrade the target pollutants.

In many cases, bioremediation is less expensive and more sustainable than other remediation alternatives. Biological treatment is a similar approach used to treat wastes. This study aims to investigate the physical and chemical effects of interactions between groundwater and surface water (GW–SW)—particularly in streams—on nitrate contamination.

The effects of GW–SW interactions are briefly reviewed, with a particular emphasis on processes and environments that influence increases or decreases in nitrate by:.

The addition of sulfate to an anaerobic petroleum-contaminated aquifer in which benzene was a major soluble contaminant resulted in removal of benzene from the groundwater. The loss in benzene was associated with a decrease in sulfate along the groundwater flow path, relative to a conservative bromide tracer.
