This Ground-Water Treatment Technology Resource Guide is intended to support decision-making by
Regional and State Corrective Action permit writers. Remedial Project Managers (RPMs), On-Scene Coordina-
tors, contractors, and others responsible for the evaluation of technologies.  This Guide directs managers of sites
being cleaned up under the RCRA, UST, and CERCLA waste programs to ground-water treatment technology
resource documents, databases, hotlines, and dockets and identifies regulatory mechanisms (e.g.. Research
Development and Demonstration Permits) that have the potential to ease the implementation of ground-water
treatment at hazardous waste sites.

This Guide provides abstracts of representative examples of over 50 ground-water treatment technology guidance/
workshop reports, overview documents, studies and demonstrations, and other resource guides. The Ground-
Water Treatment Technology Resource Matrix, which  accompanies this Guide, identifies the in situ treatment
technology and contaminants covered in each abstracted document. Information contained in this Guide is not
intended to be all-inclusive, nor does the inclusion of information represent an endorsement by the U.S. Environ-
mental Protection Agency (EPA).

                                        INTRODUCTION
EPA is committed to identifying the most effective and efficient means of addressing the thousands of hazardous
waste sites in the United States. Therefore, the Office of Solid Waste and Emergency Response's (OSWER's)
Technology Innovation Office (TIO) at EPA is working in conjunction with the EPA Regions and research
centers and industry to identify and further the implementation of innovative treatment technologies.

The goal of OSWER is to encourage the development and use of innovative hazardous waste treatment technolo-
gies. One way of enhancing the use of these technologies is to ensure that decision-makers can avail themselves
of the most current information on technologies, policies, and other sources of assistance. This Guide was
prepared to help identify documents that can directly assist RPMs and permit-writers in investigating existing
information on ground-water treatment technologies applications for contaminants usually found at RCRA. UST,
and CERCLA sites.

                                    HOW TO USE THIS GUIDE

Department of Defense Biotechnology Workshop on Soil and
Ground-Water Decontamination Applications.   Various
bioremediation techniques for treating soil and water contami-
nated with sludges, solvents, toxins, acids, bases, and heavy
metals were discussed as well as the overall place of biotechnol-
ogy in Installation Restoration programs. Among the specific
applications discussed were:  biochemical sensors to determine
environmental stress in organisms; in situ detoxification and
biodecontammation of pollutants in soils and waste streams;
sequestration, removal, and recovery of metals in waste streams
with metal-binding proteins; and the use of vegetation to limit
the transport to sequester and/or to remove contaminants from

Bioremediation is defined in the article as the process by which
microorganisms are stimulated to rapidly degrade hazardous
organic contaminants to environmentally  safe levels  in soils,
subsurface materials, water, sludges, and residues. Stimulation
is achieved by the addition of nutrients and a terminal  electron
acceptor, usually oxygen, because most biological reactions
occur faster under aerobic than anaerobic conditions. Under
anaerobic conditions, nitrate has been  used  as the terminal
electron acceptor. The microorganisms use the contaminants as
a food source and convert the contaminants into biomass and
harmless by-products of metabolism such as CO, and inorganic
salts.  Usually bioremediation is used to degrade contaminants
that are sorbed to surfaces or dissolved in  water rather than to
degrade pure chemicals.  As a result, the process is used in
conjunction with other techniques in remediation of contami-
nated sites.  The contaminants can be biodegraded in situ or
removed and placed in a bioreactor. which can be placed off or
at the site where the contamination occurred.

In situ bioremediation, which is the managed, in-place cleanup
of contaminated ground water aquifers and surface soils  by
microorganisms, is a promising technology because it is versa-
tile and can have significant  economic advantages. Many
common contaminants are biodegradable, and new microbial
capabilities for degradation are being discovered all the time.
Success in the field and  in laboratory studies point out the
promise. On the other hand, the promises are not yet fulfilled,
mainly because of the  complexity of the subsurface situation.
The report provides  a comprehensive and in-depth critical
review of in situ bioremediation.  It is organized to evaluate the
possibilities and restrictions inherent in all facets of in situ
bioremediation, including microbiology, hydrodynamics, en-
gineering, and legal and other nontechnical aspects. Several of
the key conclusions are illustrated by case studies of successful
field projects. Finally, the research needed to advance in Mtu
bioremediation to become a reliable and acceptable tool is
outlined.

ber 1993
  EPA Document Number:  EPA/540/R-93/080
  NTIS Document Number: PB93-963507/XAB
This guidance clarifies how EPA will determine whether ground
water restoration is technically impracticable and what alterna-
tive measures or action must be undertaken to ensure that the
final remedy is protective of human health and the environment.
Topics covered include the types of technical data and analyses
needed to support EPA's evaluation of a particular site and the
criteria used to make a determination. As technical impractica-
bility (TI) decisions are part of the process of site investigation,
remedy selection, remedial  action, and evaluation of remedy
performance, the guidance  also briefly discusses the overall
framework for decision making  during these  phases of site
cleanup.

Superfund sites (both remedial and emergency response ac-
tions) and non-Superfund  sites (within the  Departments of
Defense and Energy) where innovative treatment technologies
have been or are being used. Innovative treatment technologies
are treatment technologies for which a lack of data on cost and
performance makes their selection and use at Superfund sites
more difficult. The report documents the use of the following
innovative treatment technologies to treat ground water in situ:
soils, sediments, sludge, and solid-matrix wastes: bioremediation
(ex situ); bioremediation (in situ); chemical treatment: dechlo-
nnation; in situ flushing; in situ vitrification: soil vapor extrac-
tion; soil washing; solvent extraction: thermal desorption: and
other technologies.

In-situ bioremediation. where applicable, appears to be a poten-
tial cost-effective and environmentally acceptable remediation
technology. Suflita (1989) identified characteristics of the ideal
candidate site  for  successful  implementation of in-situ
bioremediation. These characteristics included:  (1) a homoge-
neous and permeable aquifer: (2) a contaminant originating
from a single source: (3) a low ground-water gradient; (4) no
tVee  product: (5)  no soil contamination; and  (6) an easily
degraded, extracted,  or immobilized contaminant. Obviously,
few sites meet these characteristics. However, development of
information concerning site-specific geological  and microbio-
logical characteristics of the aquifer, combined w ith knowledge
concerning potential chemical, physical, and biochemical  fate
of the wastes present, can be used to develop a bioremediation
strateev for a less-than-ideal site.

The report provides the reader with a detailed background of the
technologies available for the bioremediation of contaminated
soil and ground water.  The document has been prepared for
scientists, consultants, regulatory personnel, and others who
are associated in some way with the restoration of soil and
ground water at hazardous waste sites.  It provides the  most
recent scientific understanding of the processes involved with
soil and ground-water remediation, as well as a definition of the
state-of-the-art technologies with respect to circumstances of
their applicability and their limitations.  In addition to discus-
sions and examples of developed technologies, the report also
provides  insights  to emerging technologies that are at the
research level of formation, ranging from theoretical concepts.
through bench-scale inquiries, to limited field-scale investiga-
tions.  The report centers around a number of bioremediation
technologies applicable to the various subsurface compart-
ments into which contaminants are distributed. The processes
that drive these remediation technologies are discussed in depth
along  with the  attributes that direct their applicability and
limitations according to the phases into which the contaminants
have partitioned. These discussions include in situ remediation
systems, air sparging and bioventing. use of electron acceptors
alternate to oxygen, natural bioremediation. and introduction of
organisms into the subsurface.  The contaminants  of major
focus in the report are petroleum hydrocarbons and chlorinated
solvents.

The  Robert S. Kerr Environmental Research  Laborator>
(RSKERL) has developed a number of issue papers and brief-
ing documents that are designed to exchange up-io-date infor-
mation related to the remediation of contaminated soil and
ground water at hazardous waste sites. In an attempt to make
the content of these documents available to a w ider audience.
RSKERL  is developing a series of summary  papers that are
condensed versions of the original documents.  There are a
number of techniques that may potentially be used for dealing
with problems resulting from the contamination of ground
water with organic compounds.  Ground water can sometimes
be treated  in place using chemical or biological processes. An
emerging  technology for the in situ remediation of ground
water is the use of microorganisms to degrade contaminants
that  are present  in  aquifer materials.  Although in situ
bioremediation has been  used for a  number of years in the
restoration of ground water contaminated with petroleum hy-
drocarbons, its application to other classes of contaminants is
relatively recent. This is discussed in the summary paper.

The predominance of ground-water contamination at hazard-
ous waste sites and the dearth of methods to efficiently treat this
contamination is a problem that the U.S. Environmental Protec-
tion Agency (EPA) is examining. The contaminated ground
water found at most Superfund sites is often the limiting factor
for complete site remediation. The purpose of the document is
to describe recent research, development, and application of
technologies that either treat ground-water contaminants in
place or improve the solubility and mobility of contaminants to
enhance pump-and-treat remediation effectiveness. The report
discusses techniques that can be applied  in situ and excludes
pumping methodologies  or surface treatment systems.  In
addition, the publication presents conclusions based on obser-
vations of the survey. Finally, strategies  for action for stake-
holders concerned with in situ ground-water technology devel-
opment are presented. The study has not defined the extent or
activities of research and development outside of EPA-sup-
ported groups.

Because of the limitations of pump-and-treat technology, atten-
tion  is now focused  on the feasibility of surfactant use  to
increase its efficiency. Surfactants have been studied for use in
soil washing and enhanced oil recovery. Although similarities
exist between the applications, there are significant differences
in the objectives of the technologies and the limitations placed
on surfactant use.  This  article reviews environmental studies
concerned with the fate and transport of surface-active com-
pounds in the subsurface environment and discuss key issues
related to their successful use for in situ aquifer remediation,
particularly with respect to nonaqueous-phase liquids.

 Technologies to Remediate Hazardous Waste Sites.
 Falco, J.W., Battelle Pacific Northwest Laboratories,
 Richland, WA, March 1990
   NTIS Document Number: DE90-011946/XAB
 Technologies to remediate hazardous wastes must be matched
 with the properties of the hazardous materials to be treated, the
 environment in which the wastes are imbedded, and the desired
 extent of remediation.  Many promising technologies are being
developed and applied to remediate sites including biological
treatment, immobilization techniques, and in situ methods. The
management and disposal of hazardous wastes is changing
because of Federal and  State legislation,  as well as public
concern. Future waste management systems will emphasize the
substitution of alternatives for the use of hazardous materials
and process waste recycling.  On site treatment will  also
become more frequently adopted.

Air sparging, also called "in situ air stripping" and "in situ
volatilization," injects air into the saturated zone to stnp away
volatile organic compounds (VOCs) dissolved in ground water
and adsorbed to soil. These volatile contaminants transfer in a
vapor phase to the unsaturated zone where soil vapor extraction
(SVE) can then  capture and remove them.  In addition  to
removing VOCs via mass transfer, the oxygen in the injected air
enhances  subsurface biodegradation of contaminants.  Air
sparging is a relatively new treatment technology.  Research
efforts have not  yet fully elucidated the scientific  basis (or
limitations) of the system, nor completely defined the associ-
ated engineering aspects.   However, a substantial body  of
available information describes the effectiveness and charac-
teristics of air sparging systems. This document summarizes
the available literature and addresses case studies of practical
air sparging applications. It also identifies needs for further
research.

          STUDIES AND DEMONSTRATIONS

          Documents Focusing on Test Design
Rational design relates laboratory treatability studies at field
scale to the distribution of contaminants and to the residence
time of remedial fluids. The electron acceptor is usually the
limiting factor in bioremediation. Ideally, the electron acceptor
should not be depleted as water or air moves across the region
contaminated with oily phase matenal. When all of the con-
taminated mass receives adequate supplies of electron accep-
tor, the course of redemption should parallel that established in
the laboratory study.  If regions of the contaminated mass are
not adequately supplied, the course of remediation at field scale
is not predicted in any straightforward way from the laboratory
study.  Rational design compares the residence time and con-
centration of electron acceptor at field s^ ile  to the  demand
demonstrated for the electron acceptor in the laboratory to
ensure that the engineered implementation  of in  situ
bioremediation is adequate.

 Degradation of chlorinated alkenes such as tnchloroethylene
 (TCE) by methanotrophic bacteria is a promising technology
 for the remediation of contaminated ground water. Ultimately,
 the success of this approach may be dependent on the influence
 of ground-water chemistry on degradation rates and extent.
 TCE can rapidly be reduced to low levels in laboratory cultures
 growing on defined media.  However, if major changes in
 ground-water chemistry are necessary to achieve substantial
 TCE degradation, field application of processes (i.e.. above-
 ground and in situ treatment) may be limited by cost or logistic
 problems. For example, the presence of competitive inhibitors
 may limit the extent of TCE degradation.  The goal of the
 research is to quantify the potential effects of ground-water
 chemistry on the biodegradation of TCE by methanotrophs and
 to define concentrations of methane that need to be added to the
 system  to produce maximum rates of TCE degradation. This
 includes evaluation of major nutritional  requirements (e.g.,
 PO ) in addition to the focus on competitive inhibition.

An experimental investigation using an artificial aquifer was
conducted on in situ denitnfication. Methanol substrate was
injected into  the aquifer to enable denitrifying bacteria to
convert the nitrates into nitrogen. The experiment in the study
provided a database that was used to evaluate mathematical
simulations of the processes involved.  Numerical dispersion
was  found to be a critical characteristic  of the numerical
solution technique.  Density drive and plugging of the aquifer
due to biological growths were found to be important processes
that need to be considered in future simulations.

This report presents a systematic approach for the design of in
situ bioremediation of hydrocarbon contamination in ground
water from the determination of the total quantity of hydrocar-
bons in the aquifer to the utilization of that information in an
actual field demonstration.  This report explains why the total
quantity of hydrocarbons in an aquifer can only be determined
by collecting cores.  A procedure to acquire cores from a
contaminated aquifer is described. The procedures described in
the report were field tested in designing a demonstration of the
bioremediation of an aviation gasoline leak. The performance
of the demonstration was consistent with the expected perfor-
mance based on the preliminary site characterization using the
described procedures.

The report summarizes the behavior of and requisite conditions
for a class of natural biological processes that can transform
chlorinated aliphatic compounds.  These  compounds   are
among the most prevalent hazardous chemical  contaminants
found in municipal and industrial wastewaters, landfills and
landfill leachates, industrial disposal sites, and ground water.
Biological degradation is one approach that has the potential for
destroying hazardous chemicals so that they can be rendered
harmless for all time.  Methodologies are presented that are
useful for evaluating the potential for biorestoration of ground
water contaminated with chlorinated aliphatic compounds.
Section  1 provides an introduction  and an overview of the
problems with  chlorinated aliphatic compounds in ground
water. Section 2 presents a review of the processes affecting the
movement and fate of chlorinated aliphatics in the subsurface,
including advection, dispersion, sorption and relative mobility,
diffusional transport, and immiscible transport. Methodologies
and results are presented for evaluating the presence of a native
methantrophic community and its ability to degrade the con-
taminants of concern, determining the sorption of contaminants
to the aquifer material, and preliminary designing of an in situ
treatment approach using the model previously described.

 ment of in situ remediation technologies. The development of
 in situ remediation technologies will focus on five problem
 groups: buried waste, contaminated soils, contaminated ground
 water, containerized wastes, and underground detonation sites.
 The contaminants that will be included in the development
 program are volatile and nonvolatile organics, radionuclides,
 inorganics, and highly explosive materials, as well as mixtures
 of these contaminants.  The In Situ Remediation Integrated
 Program (ISRIP) has defined the fiscal year 1993 research and
 development technology areas for focusing activities, and they
 are described in this paper.  These R&D topical areas include:
 nonbiological in situ treatment, in situ bioremediation, electro-
 kinetics, and in situ containment.

 Two horizontal wells were installed adjacent to an abandoned
 process sewer line at the Savannah River Plant.  Documented
 leaks from the process sewer have contaminated the underlying
 vadose zone and ground  water with volatile organic com-
 pounds. The wells were installed to test new methods of in situ
 remediation of soils and ground water. A deep horizontal well.
 installed below the water table, is to be used as an air-injection
 well to strip  volatile organics from the contaminated ground
 water.  The shallow horizontal well, installed in the vadose
 zone,  is to be  used to remove vapor-phase volatile  organic
 compounds from the vadose zone and to recover the organics
 purged from the ground water.  Horizontal wells were selected
 for  injection and extraction  because this geometry should
 maximize the surface area available for in situ remediation
 reactions to occur.  Target zones for the lateral well screens
 were selected on the basis of (1) concentrations of volatile
 organic compounds in ground water from nearby monitoring
 wells, and (2) porosity and permeability of the sediments as
 determined by core analysis, geophysical logs, and sieve analy-
 ses.

injecting a fluid into a saturated zone on one side of the plume
and an extracting well for collecting the fluid together with
volatilized contaminants from the plume on the other side of the
plume, is described. The fluid enables the volatile contami-
nants to be volatilized and carried through the ground to the
extracting  well. Injecting and extracting wells are preferably
horizontal  wells positioned below the plume in the saturated
zone and above the plume in the vadose zone. The fluid may be
air or other gas or a gas and liquid mixture depending on the type
of contaminant to be removed and may be preheated to facilitate
volatilization. Treatment of the volatilized contamination may
be by filtration, incineration, atmospheric dispersion, or the
like.

This project is designed to demonstrate in situ bioremediation
of ground water and sediment contaminated with chlorinated
solvents.  Indigenous  microorganisms  will be simulated to
degrade trichloroethylene (TCE), tetrachloroethylene (PCE)
and their daughter products in situ by addition of nutrients to the
contaminated zone. In situ biodegradation is a highly attractive
technology for remediation because contaminants are destroyed,
not simply moved to another location or immobilized,  thus
decreasing costs, risks, and time, while increasing efficiency
and public and regulatory acceptability.  Bioremediation has
been found to be among the least costly technologies in appli-
cations where it will work.

An in situ bioremediation project has been designed and con-

A pipeline leaked an unknown quantity of refined fuels in the
1970s. The spill was undetected until hydrocarbons were found
in a nearby municipal water supply well.  Of concern, from a
regulatory perspective, are the alky Ibenzene components found
in the ground water, including benzene, toluene, ethylbenzene,
and xylene (BTEX). Initial abatement procedures, including
free product removal and pumping, had become ineffective. In
situ bioremediation was selected to complete  the restoration
process. The project emphasizes the need for a strong under-
standing of the geologic and hydrogeologic conditions preva-
lent under the site. Site studies were conducted to determine the
distribution and mass of the contaminant and the hydraulic
regime.  Laboratory microbial studies were used to determine
the efficacy of nitrate as a primary electron acceptor.  Informa-
tion from site studies was used to design a treatment system
tailored to the requirements of the site. The treatment system is
designed to deliver the maximum amount of nutrient-enriched
water to the  contaminated zone while maintaining hydraulic
control of the site.

A project to remove groundwater contaminants by an improved
treatment  process was  performed during  October  1990 to
March 1992 by Atomic Energy  of Canada Limited for the
United States Department of Energy,  managed by Argonne
National Laboratory. The goal was to generate high-quality
effluent while minimizing secondary  waste volume.  Two
effluent target levels, within an order of magnitude or less of the
U.S. Drinking Water Limit, were set to judge the  process
effectiveness.  The program employed mixed waste feeds
containing cadmium, uranium, lead, iron, calcium, strontium-
85-90, cesium-137,  benzene, and trichloroethylene  in simu-
lated and  actual groundwater and soil leachate solutions.  A
combination of process steps that included sequential chemical
conditioning, cross-flow microfiltration anddewatering by low
temperature-evaporation, and filter pressing were effective for
the treatment of mixed waste having diverse physicochemical
properties. Overall test results revealed a three-step chemical
treatment / microfiltration sequence combined with a final
dewatering step is optimal.

Soil vapor extraction (SVE) has been shown to be effective at
removing hydrocarbons from the unsaturated zone. How-ever.
at many spill sites significant fractions of the mass are at or
below the water table, in which case SVE is  far less effective.
To improve its efficiency in cases where gasoline is trapped
below the water table, SVE can  be used in  conjunction with
other techniques to get at that trapped mass. In the last few years
the direct injection of air into the formation below the water
table (i.e., in situ sparging) has become a popular technique.
Another approach is to lower the water table to improve airflow
in the vicinity of the trapped product. This can be accomplished
either in the localized area of a ground water draw down cone
or as the result of larger scale  dewatering.  In  experiments
conducted at the Oregon Graduate Institute (OGI), hydrocar-
bon spills into a large three-dimensional physical model filled
with sand are being used to study the efficiencies of SVE
combined with other techniques.  Experiments to date have
examined SVE operating as a stand-alone technique, as well as
in conjunction with air sparging below the water table, dewater-
ing of the  "smear zone" (i.e., where product is trapped  as
residual below the  water table), and air injection into  the
dewatered smear zone.

Tetrachloroethylene (TCEK a solvent and de-greasing agent, is
widely spilled and disposed of on soil. It is easily transported
in ground water, causing wide-spread aquifer contamination.
Conventional technology for the treatment of solvent-contami-
nated aquifers,  which involves  pumping out the water and
above-ground treatment by  physical/chemical techniques, is
slow  a~nd expensive.   Cambridge Analytical Associates
Bioremediation Systems has carried out experiments to demon-
strate the feasibility of in situ biodegradation of TCE.  The
process would involve controlled addition of nutrients to the
ground water to stimulate the activity of naturally occurring
bacteria.  A 23 liter laboratory aquifer simulator was con-
structed and filled with soil, and amended ground water was
recirculated throughout the soil.  Methanogenic conditions
were brought about in the reactor within 15 days  and TCE was
shown to degrade rapidly to dichloroethylene.  Oxygen was
then introduced and the oxidation of dichlororethylene by
methanotrophic bacteria was initiated. The aquifer simulator
experiment indicated that aquifer conditions can be manipu-
lated in situ to bring about the complete degradation of TCE.

 A fundamental understanding of both transport and transforma-
 tion processes is essential to the development of technically
 sound remediation strategies for ground water contamination.
 Accordingly, the goal of the project is to enhance the rate and
 efficiency of in situ microbial degradation of subsurface con-
 taminants through an improved understanding of processes that
 govern transport, attachment, growth, and activity of microor-
 ganisms  in porous media.  The  report is organized into the
 following sections:  1) Transport Processes: contains experi-
 mental methods and results that document the effect of biofilm
 accumulation on the transport of water, nutrients, and sus-
 pended cells in one-dimensional porous media flow  reactions,
 2) Effects of Cell Starvation and Motility: presents experimen-
 tal procedures and results describing transport characteristics of
 starved vs. growing and motile vs. nonmotile cells  in porous
 media, 3) Modeling  Microbial Transport and Activity:  de-
 scribes development of a mathematical model that  simulates
 contaminant biodegradation/biosorption, nutrient depletion and
 biomass  accumulation in one-dimensional porous media flow.
 and 4) Bioremediation Guidelines: summarize relevant infor-
 mation in the form of guidelines useful to decision-makers
 concerned with bioremediation of contaminated water and soil.

In situ biodegradation may be used to treat low-to-intermediate
concentrations of organic contaminants in place without dis-
turbing or displacing the contaminated media.  Although this
technology has been used to degrade a limited number of
inorganics, specifically cyanide and nitrate, in situ biodegrada-
tion is not generally employed to degrade inorganics or to treat
media contaminated with heavy metals. During in situ biodeg-
radation, electron acceptors (e.g., oxygen and  nitrate), nutri-
ents, and other amendments may be introduced into the soil and
groundwater to encourage the growth of an indigenous popula-
tion capable of degrading the contaminants of concern.  These
supplements are used to control or modify site-specific  condi-
tions that impede microbial activity  and. thus, the rate and
extent of contaminant degradation. Depending on site-specific
clean-up goals, in situ biodegradation can be used as the sole
treatment technology or in conjunction with other biological.
chemical, and physical technologies in a treatment-train.  In the
past, in situ biodegradation has often been  used to enhance
traditional pump and treat technologies. As of Fall 1993.in>itu
biodegradation was being considered or  implemented as  a
component of the remedy at 21 Superfund sites and 38 RCRA.

The objective of this program was to quantitatively assess the
effectiveness  of in situ electrolysis of ground water on the
growth of soil microorganisms. The electrolysis method was
used to supply  oxygen to soil microorganisms  to enhance
bioremediation of sites that are contaminated with hydrocar-
bons. Electrochemical tests were performed with two different
types of soils in a 10-gallon glass container.   Experimental
variables examined included driving voltage, current, and elec-
trode spacing. Stainless steel mesh was used for both the anode
and the cathode. Depending on the soil, a sustained supply of
dissolved oxygen up to 16 ppm was achieved. The population
of soil microorganisms increased with increasing the oxygen
content in the ground water. A slight decrease in the population
was  seen at the cathode, which might have been due to  an
increase in the pH at the cathode.

In situ steam extraction removes  volatile and  semivolatile
hazardous contaminants from soil and ground water without
excavation of the hazardous waste.  Waste constituents are
removed in situ by the technology and are not actually treated.
The use of steam enhances the stripping of volatile contami-
nants  from soil and can be used  to displace contaminated
ground water under some conditions. The resultant condensed
liquid contaminants can be recycled or treated prior to disposal.
The steam extraction process is applicable to organic wastes but
has not been used for removing insoluble inorganics and metals.
Steam is injected into the ground to raise the soil temperature
and drive off volatile contaminants. Alternatively, steam can be
injected to form a displacement front by steam condensation to
displace  ground water. The  contaminated liquid and steam
condensate are then collected for further treatment. Two types
of systems are discussed in the document:  1) the mobile system
and 2)  the stationary system. The bulletin provides information
on the technology applicability, limitations, a description of the
technology, types of residuals produced, site requirements, the
latest  performance data, the  status of the technology,  and

monitoring well located at least 2300 ft. downgradient from the
site also had CC14 and CHC13 contamination. Furthermore, a
public water supply well, located downgradient of the site, was
found to have ground water contaminated with CC14.  During
two years of operation of the remedial action, ground-water and
soil gas samples have  been analyzed  to monitor potential
migration of contaminants from the site and to track the overall
progress toward cleanup. Results demonstrate a decrease in
ground-water contamination in both on- and off-site monitor-

 Performance of in situ bioremediation was demonstrated at a
 shallow water site with subsurface contamination of used crank

 Treatment  involved ground-water amendment  by  hydrogen
 peroxide and nutrients by a recharge gallery.  The system was

 water table containing significant  amounts of hydrocarbons.
 The center of the interval had not been depleted  of BTEX
 compounds, but the surrounding cortex had been physically and
 biologically weathered. The interval material was fine textured
 which  restricted flow of remedial fluids resulting in little

 m) deep in the  vadose  zone,  was used to extract  residual
 contamination in the  vadose zone along with the  material
 purged from the ground water. Pre-test and post-test character-

extract fluids from the subsurface because their geometry can
maximize the efficiency of a remediation system and they have
great  potential for remediating  contaminant sources  under
existing facilities. The first demonstration of this new technol-

of VOCs  was obtained. Air was then injected at three different
rates and at two different temperatures. An extensive character-
ization program was conducted  at the site and an extensive
monitoring network was installed prior to initiation of the test.
Significant quantities of VOCs have been removed from the
subsurface (equivalent to an eleven-well, 500-gpm, pump-and-
treat system at the same site). Concentrations of VOCs in the
ground water have been significantly reduced in a number of the
monitoring wells.

Effective in situ bioremediation strategies require an under-
standing of the effects pollutants and remediation techniques
have on subsurface  microbial communities.  Therefore, de-
tailed characterization of a site's microbial communities is
important.  Subsurface sediment borings and water samples
were collected from a trichloroethylene (TCE)-contaminated
site, before and after horizontal well in situ air stripping and
bioventing, as well as during methane injection for stimulation
of methane-utilizing microorganisms. Subsamples were pro-
cessed for heterotrophic  plate counts, acridine orange direct
counts (AODC), community diversity, direct fluorescent anti-
bodies (DFA) enumeration for several nitrogen-transforming
bacteria, and Biolog (regsign) evaluation of enzyme activity in
collected water samples.  Plate counts were higher in near-
surface depths  than  in the vadose  zone sediment samples.
During the in situ air stripping and bioventing, counts increased
at or near the saturated zone and remained elevated throughout
the aquifer, but did not change significantly after the air strip-
ping.  Sporadic increases in plate counts at different depths as
well as increased diversity appeared to be linked to differing
lithologies. AODCs were orders of magnitude higher than plate
counts and remained relatively constant with depth except for
slight increases near the surface depths and the capillary fringe.
Nitrogen transforming bacteria, as measured by serospecific
DFA, were greatly affected both by the in situ air stripping and
the methane injection. Biolog (regsign) activity appeared to
increase with subsurface stimulation both by air and methane.
The complexity of subsurface systems makes the use of selec-
tive monitoring tools imperative.

matrixes. Microencapsulated bacteria at PCP concentrations up
to 275 ppm and free cells at PCP concentrations < 150 ppm can
remain active for extended  periods under simulated aquifer
conditions. Periods of several months are certainly attainable.
This should be sufficient time to effect significant environmen-
tal restoration through biodegradation of specific targeted pol-
lutants.
Surfactant Flooding Technology for In Situ Cleanup of
Contaminated Soils and Aquifers—A Feasibility Study.
Porzucek. C. U.S. Department of Energy. Los Alamos
National Laboratory, NM, November 1989
  NTIS Document Number:  DE90-003989/XAB
The process of in situ, surfactant-enhanced soil washing has
been investigated to determine its usefulness and limitations.
Previous work on this subject has been reviewed critically.
Entrapment/displacement mechanisms of nonaqueous phase
liquids (NAPLs) in porous media have been identified and are
discussed. The effect of surfactant on each of these mechanisms
has been  investigated.  A joint  research project has been
initiated with  Howard University personnel to determine the
effect of surfactant  on contaminants that have adsorbed onto
soil surfaces.  Results of this research are necessary to more
fully determine the  limitations of in situ, surfactant-enhanced
soil washing.  However, based on field observations of NAPLs
and modification of an existing mass-transfer-based model, it is
apparent that  in situ, surfactant-enhanced soil  washing alone
will not be a sufficient remedial action plan because it cannot
displace enough  contaminant to clean the soil to within the
Environmental Protection Agency's guidelines of cleanliness.
The process shows the most promise when it is used in conjunc-
tion with another remedial action plan such as biorestoration.

The report analyzes the results from the Superfund Innovative
Technology Evaluation Program's 56-day demonstration at the
Valley Manufactured Product Company's site in Groveland.
Massachusetts.  Conclusions were reached concerning the
technology's suitability for use in remediations involving both
similar and different materials at other sites. Operational data
and sampling and analysis information were monitored care-
fully to establish a database against which vendor's claims for
the technology  could be evaluated.  Additional data on the
technology's performance at other sites is also discussed. The
conclusions from the results of the Groveland demonstration
test and from other available data are: 1) the process can be used
to remediate a site contaminated with VOCs: 2) the process can
remove  VOCs from soils with permeabilities as low as 10*
cm/s; 3) the process operates well in all weather conditions: and
4) the process implementation costs can be as low as $20/ton.

Treatability of Contaminated Ground Water and
Aquifer Solids at "Town Gas" Sites, Using Photolytic
Ozonation and Chemical In Situ Reclamation, Final
Report.

State Water Survey Division. Champaign. Aquatic Chemis
try Section, Illinois Department of Energy and Natural
Resources. Champaign, Hazardous Waste Research and
Information Center, August 1990
  NTIS Document Number: PB90-267253/XAB
The feasibility of cleaning up contaminated ground water and
aquifer solids from so-called "town gas" sites using photolvtic
ozonation and chemical in  situ aquifer reclamation (CISR)
techniques was investigated in the laboratory. At the actual site.
coal was thermally oxidized to produce methane for municipal
distribution. The degradation left a coal which, if released into
the ground, could contaminate ground water and aquifer solids
with a number of organic substances, including aromatic hydro-
carbons such as benzene, toluene, xylene (BTX). and poly-
nuclear  aromatic  hydrocarbons (PAHs) at  environmentally
significant concentrations. A chemical in situ treatment method
using persulfate as a source of free radicals destroyed organic
contaminants that were adsorbed to the aquifer solids. PAHs
were reduced by 34 percent after 12 days of treatment and by 52
percent after 40 days.

These documents are intended to support decision-making by
Regional and State Corrective Action permit writers. Remedial
Project Managers (RPMs), On-Scene Coordinators, contrac-
tors, and others responsible for the evaluation of innovative
treatment technologies. These guides direct managers of sites
being remediated under RCRA.  UST,  and CERCLA to
bioremediation, ground-water, physical/chemical, and soil va-
por extraction treatment technology resource documents; data-
bases; hotlines; and dockets, and identify  regulatory mecha-
nisms (e.g.. Research Development and Demonstration Per-
mits) that have the potential to ea.se the implementation of these
technologies at hazardous waste sites. Collectively, the guides
provide abstracts of over 300 guidance/workshop reports, over-
view/program  documents, studies  and demonstrations,  and
other resource guides, as well easy-to-use Resource Matrices
that identify the technologies and contaminants discussed in
each abstracted document.
