The most frequently used in situ bioremediation technique is enhanced reductive dechlorination that consists of the addition of organic substrates (electron donors) to ensure highly reducing conditions and to provide the hydrogen needed by dechlorinating organisms (ITRC ), which can be used for dissolved phase contaminants, DNAPL, and DNAPL source zones.

Although in situ bioremediation has been used for a number of years in the restoration of ground water contaminated by petroleum hydrocarbons, it has only been in recent years that in situ systems have been directed toward contaminants in unsaturated subsurface soils.
L.D. Brown, A.C. Ulrich, in Oil Spill Science and Technology (Second Edition), In Situ Bioremediation Strategies. In situ bioremediation techniques focus on initiating or enhancing the degradation of the contaminants of concern in the subsurface.
According to Brown and Crosbie , unsaturated and residually saturated soils contain the most significant petroleum hydrocarbon. Get this from a library. In situ bioremediation of contaminated unsaturated subsurface soils.

Russell Follow this and additional works at:veterans-opex.com Part of theCivil and Environmental Engineering Commons, and theWater Resource Management CommonsCited by: Dec 07, · Bioremediation of contaminated soils In Situ Bioremediation In situ bioremediation is when the contaminated site is cleaned up exactly where it occurred.
It is the most commonly used type of bioremediation because it is the cheapest and most efficient, so it’s generally better to use. There are two main types of in situ bioremediation.
treatment of contaminated soil in both the vadose zone and saturated and unsaturated source zones. The in situ technologies presented involve apply ing chemical, biological, or physical processes to the subsurface to degrade, remove, or immobilize contaminants without removing the bulk soil.
Compared to excavation and ex situ treatment, the. Bioremediation of Contaminated Soils - CRC Press Book This volume focuses on innovative bioremediation techniques and applications for the cleanup of contaminated media and sites.
It includes quantitative and design methods that elucidate the relationships among various operational parameters, and waste chemistry that defines the cost. Start studying Bioremediation exam 2. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Use moving soil gas to transfer oxygen to subsurface where indigenous microbes use as an electron acceptor to aerobically metabolize contaminants. Solid phase treatment system for contaminated soils. Soil bioremediation approaches for petroleum hydrocarbon polluted environments Reclamation and its stages and the bioremediation of oil-contaminated soils with the use of biological products.
Ex-situ bioremediation of contaminated soils (eds) Soil and sediment remediation a field guidance book for federal on-scene coordinators, version that in situ systems have been. Implementation of Bioremediation at Sites Contaminated with Organic Wastes A recent survey conducted for the U.S. EPA concerning the use of bioremediation at sites with soils contaminated with wood-preserving wastes identified ten sites that currently plan to use bioremediation techniques to cleanup contaminated soils and sediments (Table 12) .
Removal of heavily contaminated soils reduces the demands on an in situ technology and immediately reduces the potential for impact on the ground water. Where residual pools of contaminants are present in the subsurface, these pools may be removed prior to implementation of other remediation technologies by a process known as free product recovery.
Sep 16, · Ex situ bioremediation techniques are usually considered based on: the cost of treatment, depth of pollution, type of pollutant, degree of pollution, geographical location and geology of the polluted site.
Performance criteria, which also determine the choice of ex situ bioremediation techniques, have been described (Philp and Atlas ).Cited by: INOCULATION OF CONTAMINATED SUBSURFACE SOILS WITH ENRICHED INDIGENOUS MICROBES TO ENHANCE BIOREMEDIATION RATES W.
WEBER JR @ and H. CORSEUIL 2 ~Department of Civil and Environmental Engineering, The University of Michigan, Ann Arbor. An emerging technology for the remediation of unsaturated subsurface soils involves the use of microorganisms to degrade contaminants which are present in such soils.
Understanding the processes which drive in situ bioremediation, as well as the effectiveness and efficiency of the utilization of these systems, are issues which have been identified by the Regional Superfund Engineering Forum as Cited by: Remediation of Hydrocarbon Contaminated Soils Author: Andrea Milioni, Chemical Engineer – On Contract contamination, in situ, or after removing the contaminated soil, ex situ.
Among the latter, there are the treatments on site, when working on the excavation site or off site, when saturated zone, the part of the subsurface in which. AGRONOMY A Series of Monographs The American Society of Agronomy and Academic Press published the first six books in this series.
