In situ bioremediation of groundwater has become one of the most widely used technologies for contaminated site treatment because of its relatively low cost, adaptability to site-specific conditions, and efficacy when properly implemented (Stroo ).

Enhanced In-Situ Biodegradation; Above Ground Bioreactor; Contaminants: Nitrate: Description: Nitrate contamination is one of our Nation's most ubiquitous ground-water contamination problems. USGS microbiologists and their colleagues have used a two-phase approach to developing remediation strategies for nitrate contamination in ground water.

In-Situ Bioremediation of Nitrate-Contaminated Ground Water A Pilot Test, Julesburg, Colorado, ByP.B. McMahon, K.F. Dennehy, andB.W.

A novel approach for the in situ bioremediation of acidified, nitrate-contaminated groundwater was developed.

Ethanol was introduced into the groundwater to enhance the activity of intrinsic denitrifying micro-organisms. Infiltration of the carbon source was made via an infiltration gallery constructed in the unsaturated zone to avoid clogging problems and to allow wider distribution of Cited by: Bioremediation technologies for soil Composting – addition of moisture and nutrients, regular mixing for aeration Biopiles – ex-situ aeration of soil Bioventing – in-situ aeration of soil Land treatment – application of organic materials to natural soils followed by irrigation and tilling.

Nitrate contamination in groundwater is a common problem throughout the United States. Human consumption of nitrate-contaminated water has been shown to cause Blue Baby Syndrome and may be involved in other health problems including cancer.

Although drinking water can be treated above the ground to remove nitrate, this approach does not address the contamination remaining in the. In situ bioremediation refers to treatment of soil in place. In situbiostimulation treatments usually involve bioventing, in which oxygen and/or nutrients are pumped through injection wells into the soil.

It is imperative that oxygen and nutrients are distributed evenly throughout the contaminated soil. A novel in situ technology for the treatment of nitrate contaminated groundwater Article (PDF Available) in Water Research 36(14) August with Reads How we measure 'reads'.

A novel in situ membrane technology was developed to remove nitrate (NO 3-) from ne-fed hydrogen gas (H 2) was used as an electron donor to stimulate denitrification.A flow-through reactor fit with six hollow-fiber membranes (surface area=93cm 2) was designed to simulate groundwater flowing through an aquifer with a velocity of m/ by: Special Issue "Groundwater Contamination and Remediation" Print Special Issue Flyer; (e.g., pump-and-treat), or in-situ methods (e.g., bioremediation or chemical oxidation).

The aim of this Special Issue of Water is to present new research contributions in the broad area of groundwater contamination and remediation.

This topic includes. Bioremediation can either be carried out ex situ or in situ, depending on several factors, which include but not limited to cost, site characteristics, type and concentration of pollutants.

Specific challenges of in situ bioremediation: Bioremediation techniques have been tested in laboratories with good results but the transfer to the field has been often quite difficult (Sturman et al., ; Allard and Neilson, ). Microbial processes play an extremely important role in in situ groundwater treatment technologies.

The assumption of carbon limitation is the basis for addition of carbon-based substrates to a system, in the development of bioremediation schemes for nitrate-contaminated groundwater.

Although many materials have been proposed for thisCited by: 2. Sulfate is ubiquitous in groundwater, with both natural and anthropogenic sources. Sulfate reduction reactions play a significant role in mediating redox conditions and biogeochemical processes for subsurface systems.

They also serve as the basis for innovative in situ methods for groundwater remediation. An overview of sulfate reduction in subsurface environments is provided, along with a Cited by:. Abstract.

Contaminated sites can pose a significant risk to public health and the environment. Many different insitu or ex-situ remediation technologies have been developed throughout the years to mitigate the risk imposed by soil contamination.

These technologies may be contaminant and site by: Abstract. Bioremediation of uranium contaminated groundwater was tested by delivery of ethanol as an electron donor source to stimulate indigenous microbial bioactivity for reduction and immobilization of uranium in situ, followed by tests of stability of uranium sequestration in the bioreduced area via delivery of dissolved oxygen or nitrate at the US Department of energy's Integrated Field.One in situ technique that shows promise is remediation, which uses microorganisms to anaerobically degrade contaminants.

In bioremediation in situ, the microorganisms that are already present in the ground utilize nutrients that are injected into the ground to metabolize the contaminants into nonhazardous materials.
