Engineered Bioremediation of a Diesel-impacted Aquifer • Menziken, Switzerland • years • GW pumped from S2 or KB12 • Water aerated and amended with KNO3 (84 mg/L nitrate) and ammonium phosphate • Re-injected in S3 connected to infiltration gallery Hunkeler et al., J. Contam. Hydro., 59, , source of dense non-aqueous phase liquid (DNAPL) that penetrates groundwater, and a plume of groundwater that becomes contaminated as it flows by the source, leading to a downgradient contaminated plume (Cherry et al., ). In situ bioremediation strategies may be directed towards containing the plume or cleaning it up completely.

Perchlorate to chloride and water, two innocuous products. The main challenge for implementing in situ perchlorate bioremediation is effectively mixing an electron donor into the perchlorate-contaminated groundwater, and delivering the mixture to the indigenous perchlorate-reducing bacteria, without having to extract water from the subsurface.

The Waterloo Emitter is a simple, low cost device designed for the controlled and uniform release of oxygen, or other bioenhancing amendments, to encourage and sustain the growth of microorganisms required for in-situ bioremediation of contaminated groundwater.

Enhancement of in situ anaerobic biodegradation of BTEX compounds was demonstrated at a petroleum-contaminated aquifer in Seal Beach, CA. Specifically, combined injection of nitrate and sulfate into the contaminated aquifer was used to accelerate BTEX removal as compared to remediation by natural attenuation.

An array of multi-level sampling wells was used to monitor Cited by: Perchlorate can be removed from drinking water or groundwater by physical-chemical processes such as ion exchange or reverse osmosis, but these processes produce waste brine that can be challenging to manage.

Biological processes break down the perchlorate into harmless chloride ions (Cl-) and oxygen gas (O2).

Contaminated groundwater is the largest liability in the Defense Environmental Restoration Program. In many cases, groundwater resources have been contaminated with various organic contaminants as a result of a legacy of past usage and disposal.

Chemicals used at the ground surface, over time, migrate into groundwater. EOS Products are formulated to optimize in situ remediation of contaminated soil and groundwater. We provide electron donors for chlorinated solvents, electron acceptors for petroleum products, bioaugmentation cultures for low microbe populations, iron formulations to enhance anaerobic reductive dechlorination, and a variety of supplements designed to.

Keywords bioremediation, biodegradation, micro-organism, in-situ, contaminated, soil, groundwater Abstract Current and previous polluting activities have caused our urban nature to become ever so more contaminated with various pollutants, some natural, some xenobiotic.

Many of these contaminated sites today are located within heavily constructed. Perchlorate, a water contaminant that interferes with the thyroid’s ability to use iodine to produce growth hormones, has been found in groundwater in a number of states including Texas.

Currently, the State of Texas has identified detectable levels of perchlorate in 28% of water systems sampled (66 out of water sources sampled). Introduction. Soil and groundwater contamination with petroleum hydrocarbon compounds causes environmental and health concerns.

Enhanced bioremediation techniques have been successfully used to remediate soils and groundwater contaminated with fuel, volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), perchlorate, and pesticides.

Pilot-scale studies have demonstrated microbial degradation of soils contaminated with munitions waste. In situ bioremediation (ISB) using reductive dechlorination is a widely accepted but relatively slow approach compared to other technologies for the treatment of groundwater contaminated by chlorinated ethenes (CVOCs).

Due to the known positive kinetic effect on microbial metabolism, thermal enhancement may be a viable means of accelerating by: 6. This report provides an overview of in situ bioremediation to remediate chlorinated solvents in contaminated soil and groundwater.
