      This report has been prepared as a part of the activities of the Data Identification and
Collection Subcommittee of the Bioremediation Action Committee (BAG). The BAG is an
affiliation of academia, government and industry representatives who share a common goal of
working collectively to expand the responsible use of biotechnology for the prevention and
remediation of environmental contamination.  All data contained within are based on vendor-
supplied information.  The data contains much variation in details and has not been verified
by the compilers.  Due to the developing nature of the bioremediation industry and the lack
of standardized testing protocols, the report has not been formally peer  reviewed by the
Agency; hence, the contents do not necessarily represent the views and  policies of the U.S.
Environmental Protection Agency or of other Federal  agencies.

      The development of this document was funded by the U.S. Environmental Protection
Agency under contract (P.O. No. 5686) to DEVO Enterprises, Inc.  Mention of company
names, trade names or commercial products does not constitute endorsement or
recommendation for hire or use.

                                    FOREWORD

       The purpose of this report and its companion report, Bioremediation Case Studies:
Abstracts, EPA/600/R-92/044, is to provide users with reference information about 132 on-
going and/or completed field applications and studies from 10 different biotechnology
companies.  About two-thirds of the cases were at full-scale clean-up level with the
remainder at pilot or laboratory scale.  The information contained in these reports was
voluntarily submitted and was not the result of a formal survey.  The report does not contain
information from all companies involved in bioremediation, only  those companies  who
responded to a request for voluntary submissions.

       These reports were prepared in conjunction with the Data Identification and
Collection Subcommittee of the EPA-Industry Bioremediation  Action Committee (BAC).
One of the objectives of the BAC is to promote the full potential  of bioremediation to treat
hazardous waste and clean-up leaks,  spills, and abandoned sites through research,
demonstrations, and technology transfer.  Due to the relative newness of bioremediation for
hazardous waste clean-up, there is, in comparison to other more widely used treatment
technologies, little information currently available.

    These reports were prepared to compile bioremediation studies in a variety of locations
and treating diverse contaminants, most of which were previously undocumented.  All data
contained in this report are based on vendor-supplied information and there was no
opportunity to independently confirm its accuracy.

       To assist the user in identifying the most useful sources of information, abstracts of
the 132 case studies have been entered into the Alternative Treatment Technology
Information Center (ATTIC) data base to augment the already existing bioremediation
information it contains. ATTIC is an on-line, key word searchable, automated data system
which provides, with out charge, information on innovative treatment technologies for
hazardous waste clean-up.  Another source of bioremediation case studies (focused primarily
on Federal and State managed clean-up) is contained in Bioremediation in the Field, a
bulletin published by the U.S. Environmental Protection Agency (EPA).

    For more information about these reports, contact Dr. Curtis  Harlin, RD-681, U.S.
EPA, Office of Research and Development, 401 M Street, S.W.,  Washington,, D.C. For
information about ATTIC contact Ms. Joyce Perdek, U.S. EPA, Risk Reduction Engineering
Laboratory, 2890 Woodbridge Ave., Edison, NJ.

                I. Purpose and Goal of the Case Study Collection
                                          A.  Purpose

 The major goal of the Bioremediation Action Committee's (BAG) Data Identification/Collection Subcommittee
 is to collect bioremediation information that exhibits the technology's benefits and costs and make this
 information available to the public and private sectors. (See Appendix A for more information on the origin,
purpose, and structure of the BAG.) One means of exhibiting such information is through an existing U.S.
 Environmental Protection Agency (EPA) Office of Research and Development (ORD) Office of Environmental
 Engineering and Technology Demonstration (OEETD)  database, the  Alternative Treatment  Technology
 Information Center (ATTIC).


 ATTIC is an information retrieval network that provides technical information on innovative treatment methods
 for hazardous wastes and other contaminants. ATTIC provides site remediation managers with information that
 can assist them in making effective decisions on cleanup alternatives. The technologies in ATTIC are classified
 as: thermal, biological, solidification/stabilization, chemical, and physical.


ATTIC information is provided in the form of an abstract of a report or case study. The abstract can include
information on: location (EPA region and state) where the technology was used, the target waste(s), the media
treated, the initial concentration(s) of contaminants), a short description of the  use of the technology, the cost
of the technology, and the final contamination concentration after use of the technology. Copies of the reports
from which abstracts are derived are available on request.  Currently, more than 1000 users access the system
each month. (See Appendix Bfor more information on ATTIC and an example  of an ATTIC abstract.)
                                           B.  Goal

The general goal of the 1991 ATTIC Bioremediation Case Study Augmentation Project was to increase the
number of bioremediation case studies available in ATTIC. Prior to the project, there were approximately 250
cases in the biological treatment portion of the database. For purposes of the project, bioremediation was defined
as the process in which soil, sludge, water, or an air stream is managed to encourage optimal activity of
microorganisms in order to biodegrade or biotransform target contaminants. Based on resources dedicated to
the project,  it was estimated that the number of bioremediation abstracts in ATTIC would be increased by 50-
100 cases.

                                       A.  Call for Data

1.  Telephone Communication

In order to guarantee a certain level of participation, a few companies, who were known to have field-level
experience and known to have the resources necessary to participate in the project, were contacted by telephone
and questioned as to their interest in participation. A follow-up letter was issued to these companies. (See
Appendix C for follow-up letter.)
2.  In—person Communication

In June 1991, a meeting was held at which the BAG delivered a progress report to EPA Administrator William
K. Reilly. More than 100 representatives of industry, government, and academia attended this meeting, which
provided the opportunity for industry representatives to comment to the Administrator on EPA's activities
concerning bioremediation.


Prior to the Administrator briefing, a poster session was held at which the BAG subcommittees displayed
information concerning their activities. For this data collection effort, information on ATTIC and a list of
bioremediation information that would be of value to ATTIC users was distributed to potential participants.
Because the list of information which would be of value to ATTIC users was fairly extensive, it was stressed
that this list was for orientation purposes  only. Companies were urged to provide such information, or
information of a similar nature, that was readily available. (See Appendix D for information handout.)
 3.  Written Communication

 a.  Federal Register Notice

 On August 7,1991, "Expansion of Bioremediation Data in the Alternative Treatment Technology Information
 Center," appeared in the Federal Register, alerting readers to the ATTIC bioremediation case study augmen-
 tation project. (Appendix E contains the Federal Register notice.)
 b. Industry News

 A story, "EPA Calls for Bioremediation Case History Information," was published in the July 1991 issue of the
 industry newspaper, Biotreatment News.

-------
                                B.   Review information submitted

1. Extent and quality of information received

The amount and quality of information initially received from the call for data was highly variable. Case study
information ranged from one to two sentences to technical reports of more than 30 pages. Sources of information
included corporate statements of qualifications, papers either presented at conferences or submitted for journal
publication, abstracts of papers presented, and descriptions of cleanup activities that were not sourced to a
specific publication.


More than 240 cases were received. However, based on established ATTIC database acceptance criteria, many
of these had too little pertinent information to warrant further investigation and were dropped from the study
at the outset. For the remaining cases, companies were contacted with questions on every case in order to ensure
that as many cases as possible were suitable for inclusion in ATTIC.
2.  Quality Assurance Fields

There are five fields in ATTIC that address quality assurance: site characterization, representative samples
taken, data quality objectives met, QA/QC objectives met, and peer review of report. The EPA definition of
each is:

   site characterization - the contaminated site was characterized for the extent and nature of contaminants
    present;
   representative sampling - a sampling strategy was designed that provided a statistical basis for estimating
    the contamination before and after the remediation activity;
   data quality objective process - the objectives for data quality were established prior to the onset of the
    study or remediation;
   QA/QC conducted - QA/QC steps, such as audits, replicate analysis, calibration of instruments,  and
    training of personnel, were used in sampling and analysis; and
   peer review - the report or the data were sent out to be reviewed by knowledgeable peers.

If definitive information is lacking, the field can be entered as "not reported."
In many cases, it was not possible for reviewers of the submitted bioremediation case study information to
ascertain the status of the data quality assurance parameters. Therefore, when information on each case was
incorporated into the ATTIC format and sent back to the participating companies for a final review, each
company was asked at that time to provide information (in a Y/N format) for the data quality assurance fields.
(See Appendix Ffor cover letter sent to participants concerning final review of cases.)

-------
                      HI.   Results of Information Collection

A total of 132 cases concerning bioremediation resulted from this project. A hard copy of all 132 cases submitted
through the 1991 ATTIC Bioremediation Case Study Augmentation Project, in the ATTIC abstract format, is
available in a separate publication, "1991 Alternative Treatment Technology Information Center (ATTIC)
Augmentation: Bioremediation Case Studies." A copy of this publication is available by calling Dr. Curtis
HarlinofOEETD/ORD/EPAat (202)260-9642; faxing(202) 260-3861; or writing Dr. HarlinatOEETD(RD-
681), Office of Research and Development, U.S. EPA, 401 M Street S.W., Washington, D.C. 20460.


Information from these collected case studies has been extracted and loaded into a database. The following are
statistics derived from this information.
                      A.  Companies Participating and Number of Cases

There were a total of 10 companies who submitted information that was suitable for ATTIC. From these
companies, as stated above, a total of 132 abstracts were prepared for the ATTIC database. These 132 cases
increase the number of biological treatment cases in ATTIC by more than 50 percent. Table 1  lists the
participating companies by name, the location of the coordinating office for the project, the number of cases for
each participating company, and percentage of total number of cases contributed by each company.

                                    B.  Stage of Cleanup

About two-thirds of the cases reported (86 cases) were at full field-scale cleanup level. Fifteen percent of the
cases (20 cases) were reported at the field pilot stage while the remaining 20 percent (26 cases) were laboratory
studies. Therefore, more than 80 percent of the cases were either at field pilot level or full scale (Table 2).

For 29 percent of the cases reported (38 cases), it was stated that there were treatment technologies used on a
particular media in addition to bioremediation (Table 3). However, it should be noted that a case study may not
necessarily have listed treatments performed in addition to bioremediation.

                                    G.  Contaminants Treated

Of the 132 cases, more than 62 percent (82 cases) reported treatment of a petroleum-related waste. In seven
of these cases, petroleum-related contaminants were treated in addition to other contaminants. Twenty-five
cases,  19  percent of the total 132 cases and 31 percent of the petroleum-related cases, were reported as
underground storage tank (UST) sites. Almost 9 percent (11 cases) involved treatment of solvents. Agricultural
(pesticides)  and wood-preserving chemicals constituted 5.3 percent (7 cases) and 9.8 percent (13 cases),
respectively, of the total 132 cases. Munitions and coal tar/tar each comprised  4 percent (5 cases). Other
contaminants were reported in 7 percent of the cases (9 cases) (Table 8).

                                       H.  Media Treated

The predominant media treated was soil. In more than 74 percent of the cases reported (98 cases), soil was at
least one of the media that was bioremediated. Treatment of soil alone constituted 46 percent of the cases
reported (61 cases), while soil and groundwater bioremediation at a single site accounted for 23 percent of the
total number of cases (30 cases). Almost 5 percent of the cases (6 cases) involved soil and sludge bioremediation
at a single site.

Cases involving bioremediation of only groundwater/water made up 16 percent of the sites reported (21 cases)
while bioremediation of groundwater/water in addition to other media comprised 39 percent (52 cases).

Treatment of sludge constituted more than 14 percent of total cases (19 cases) (Table 9),

More than 60 percent of the cases (48 cases) that involved soil at field pilot or full scale involved solely the use
of solid phase/land treatment while in more than 25 percent (21 cases), soil was treated in situ. Four percent (3
cases) reported bioreactor/bioslurry usage for soil treatment and another 5 percent (4 cases) utilized both in situ
and some type of above-ground treatment.

Of the 36 cases that registered the treatment of groundwater/water at field pilot or full scale, in 53 percent (19
cases), treatment included bringing the water to the surface and reinjecting without the use of a bioreactor.
Forty-seven percent (17 cases) indicated the use of a bioreactor for treatment. Twelve percent (5 cases) involved
treatment of groundwater totally below the surface.

            J.  Treatment Method for Soil by Year of Commencement of Treatment

Due to the large number of cases involving soil treatment, the treatment method for soil was assessed by the year
that treatment commenced. Only those cases for which a starting year was reported are listed (Table 13).

                              K.  Company Specific Information


It is interesting to note that of the cases reported, there were contrasting statistics, on a company basis,
concerning parameters such as contaminant treated, method of treatment, and location.


It should be stressed, however, that the information presented below is based solely on the 132 cases described
above. Therefore, these cases do not necessarily reflect the total range of capabilities of any participating
company and should not be construed as totally representative of company services.


L Contaminants Treated


Of the cases described above, all companies except for one (Roy F. Weston, Inc.) reported activity involving
petroleum-related waste. For six companies (ECO VA Corporation; Environmental Remediation, Inc.; Ground-
water Technology, Inc.; FT Corporation; OHM Corporation;  and Woodward-Clyde), petroleum-related
contaminants constituted the majority of work reported. The remaining companies (ABB Environmental, GET
Environmental Services, and Remediation Technologies, Inc.), had activity more dispersed among the various
contaminants (Table 14).                            •
2.  Media Treated

Of the cases described above, treatment of soil alone or soil and groundwater/water comprised the majority of
mediafor all companies except for one (Environmental Remediation, Inc.), in which case sludge and soil/sludge
were the predominant media treated (Table 15).
3. Location of Treatment

Most company activity was concentrated in one region or section of the country. However, one company
(Groundwater Technology, Inc.) registered activity in eight out of ten regions (Table 16).
                            IV.  Limitations of the Project


 Terminology was not consistent among companies, and thus in some cases, assumptions were made concerning
 the parameters reported.


 These cases do not necessarily reflect all cleanup efforts of any one company. These cases are, instead, only
 those cases on which information existed and was readily available. Consequently, individual company profiles
 may be skewed.

                 The Bio remediation Action Committee (BAG):
                           Origin, Purpose, and Structure


                                  BAC's Origin and Purpose

In February 1990, U.S. Environmental Protection Agency (EPA) Administrator William K. Reilly and the
Assistant Administrators of the Offices of Water, Pesticides and Toxic Substances, Solid Waste and Emergency
Response, and Research and Development met with representatives of industry, government, and academia. The
purpose of this meeting was to prepare an agenda for the  1990s that identified roles of the public and private
sectors and specific actions for each sector to increase environmental applications of biotechnology. As a result
of this meeting, the Bioremediation Action Committee (BAG) was formed to evaluate progress on implemen-
tation of meeting participants' suggested actions to facilitate the usage of bioremediation and to provide a
coordinated forum for continuing dialogue and action.
                                       BAG Structure

The BAG is chaired by Dr. John H. Skinner, Deputy Assistant Administrator of EPA's Office of Research and
Development (ORD).


Stephen A. Lingle, Deputy Office Director of the Office of Environmental Engineering and Technology
Demonstration, oversees the  Committee's progress. Currently, there are six BAG subcommittees, each
consisting of several representatives from industry, government, and academia and a chair who reports to the
full committee.
The'current subcommittees and their respective functions are listed in Table A-l.

SUMMARY:
   This is a report of in situ pilot-scale bioremediation at a site
   contaminated with electroplating wastes and solvents. Contaminants
   were found at varying concentrations: hydrocarbons~220-880 ppm,
   ketones~l-26 ppm, benzene and chlorobenzene~0.5-116 ppm.  Chromium
   was also present.  Soil samples were taken and mixed with groundwater.
   Microcosm and nutrients were added and incubated for 100 days.  Tests
   were done under aerobic and anaerobic conditions. Microbial
   degradation took place in both the aerobic alkane, aromatic, and
   polar hydrocarbon fractions. Chromatographic profiles for the
   anaerobic microcosm and anaerobic sterile control show similar
   chromatographic  profiles with very little or no evidence of any
   hydrocarbon degradation.  Purge and trap GC/MS were used to monitor
   anaerobic microbial degradation of chlorinated solvents. Tests
   revealed that tetrachloroethylene (PCE) and trichloroethylene (TCE)
   degraded rapidly under anaerobic conditions. Laboratory studies
   indicate in situ biological degradation of the Kelly Air Force Base
                                        23

   site is feasible. It should be noted that direct comparison cannot be
   made between total hydrocarbons before treatment and total
   hydrocarbons after treatment.  Pre-treatment samples were analyzed
   using oil and grease extractions. Post-treatment samples were
   analyzed by gas chromatography.  Oil and grease analysis quantify a
   larger category of organic compounds present in the soil, and
   therefore, concentrations should be higher than those resulting from
   GC/FIA analysis.

CONTAMINANT(S): non-volatile/volatile organic compounds (VOCs), non-
   volatile metals (electroplating wastes, sediments)

MEDIA: soil, groundwater

TECHNOLOGY: biological treatment, aerobic/anaerobic biodegradation,
      white rot fungus controls

REPORTED CONCENTRATIONS:  hydrocarbons~220-880 ppm; ketones~l-26
   ppm; benzene and chlorobenzene--0.5-116 ppm

REPORTED % REDUCTION: One  sample contained 0.071 ppm total
   hydrocarbons. Remaining samples had no detectable quantities.

ADDITIONAL INFORMATION:  Engineering and Services Laboratory, Tyndall
   AFB, FL, (904) 238-4628

COST DATA: Total cost of demonstration site: $281,850, includes
   system construction,  sampling, analysis, chemicals, other direct costs
   and labor

 HISTORY:
   This is an electroplating waste disposal site; early-mid 1960's as
   chemical evaporation pit for waste solvents and other organic
   compounds.

Dear Mr. Svendsen:

     As environmental pollution continues to escalate in our
nation, the U.S. Environmental Protection Agency's mission to
identify cost effective solutions becomes increasingly important.
To fulfill this mission, the Agency actively encourages the use
of promising innovative technologies through the dissemination of
benefits and cost information on such technologies.

     Two years ago, the EPA Office of Research and Development
created an information system on alternative innovative
technologies designed to increase communication among all parties
involved in site remediation.  This system is the Alternative
Treatment Technology Information Center, ATTIC (see enclosed
"Information Sheet on EPA's ATTIC").

     Because bioremediation is increasingly being used for
addressing pollution problems, the Office of Research and
Development is making a special effort to augment the
bioremediation information that currently exists in ATTIC with
case study information voluntarily submitted by companies such as
yours.  The EPA would be pleased to include information on any
clean-up activities in which your company has been involved.  See
enclosure, "Bioremediation Case History Information of Value for
ATTIC".

     By registering with the ATTIC system, you provide site
remediation managers with information that promotes effective
clean-up decisions.   Additionally, your organization's
contributions to site clean-ups and other pertinent company
information becomes internationally available to the average 680
monthly users of the system.
                                25

-------
  Should you choose  to  participate,  we suggest several information
  transfer methods:

  * written response: information for each case study can be
  drafted and  faxed  or  mailed.

  * telephone  communication:   information of interest can be
  discussed with a telephone  interviewer.

  * transmittal  of hard copy  text:  a copy of a paper or
  presentation on a  clean-up  activity that may have been given in a
  conference or  seminar,  or published in a trade journal, can be
  mailed.  Relevant  information will be extracted by the project
  staff.

  * on-line information transmittal:  specifics of this method can
  be discussed with  EPA representatives.

  * any combination  of  these  suggested data transfer options.

       If information is incomplete for any given clean-up, please
  keep in mind that  even partial data can be of value.
  Additionally,  information from clean-ups that may not have
  yielded expected results are also of value.  If arrangements of a
  proprietary  nature seemingly preclude participation, we recommend
  that you consider  either de-sensitizing the information of
  concern or leaving certain elements of the case study
  undiscussed, so that you will not have to forego this opportunity
  for inclusion  in ATTIC.

       If you  would  like to participate in this bioremediation
  information  collection, please call the EPA contractor
  representative, Ratherine Devine, of DEVO Enterprises, Inc., at
   (202) 543-2752. Arrangements for information transfer will be
  made.

                            Sincerely yours,
                           Gregory Ondich

  Expansion of Bioremediation Data fn
  the Alternative Treatment Technology
  Information Center

  AGENCY: Environmental Protection
  Agency.
  ACTION: Notice.

  SUMMARY: EPA's Office of
  Environmental Engineering and
  Technology Demonstration (OEETD) of
  the Office of Research and Development
  (ORD) is expanding the bioremediation
  data in the Alternative Treatment
  Technology Information Center
  (ATTIC). Bioremediation, for this
  purpose, is defined as the process in •
  which soil, sludge, water, or an air
  stream is managed to encourage optimal
  activity of microorganisms in order to
  biodegrade -or biotransform target
  contaminants. ATTIC is a computerized,
  on-line, information network that
  provides up-to-date technical
  information  on innovative treatment
  methods for hazardous wastes to ail
  members of the Federal, State, and
  private sector involved in site
  remediation. The information contained
  in ATTIC consists of a wide variety of
  data obtained from Federal, State, and
  private sector sources.
 ADDRESSES:  All interested parties may
 submit information on bioremediation to
 the following address: {Catherine Devine.

 SUPPLEMENTARY INFORMATION: As
 environmental pollution r-jmtin^tp^ to
 escalate in our nation, the U.S.
 Environmental Protection Agency's
 mission to identify cost effective  '
 solutions becomes increasingly
 important. To fulfill this mission, the
 Agency actively encourages the use of
 promising innovative technologies
 through the dissemination of benefits
 and cost information on such
 technologies.
  Two years ago. the EPA Office of
 Research and Development created an
 information system on alternative
 innovative technologies designed to
 increase communication among ail
 parties involved in cite remediation.
This system is the Alternative           29

                                           Because bioremediation is
                                         increasingly being used for addressing
                                         pollution problems, ORD is making a
                                         special effort to augment the
                                         bioremediation information that
                                         currently exists in ATTIC with case
                                         study information voluntarily submitted
                                         by the public and private sector
                                         involved in bioremediation efforts.
                                         Interested parties, including
                                         •bioremediation companies, may submit

Dear Bill:

Thank  you for  participating  in the "EPA's ATTIC  bioremediation
information augmentation project.  Enclosed you will find the final
draft hard copy version of your company's bioremediation case study
information,  that is  slated  for inclusion in ATTIC.   Do  not be
concerned  if most  of the  initial  10 fields are blank, as  such
fields are either for  the system operator's use or do not apply to
your particular case(s) .    Please review  this material  to  ensure
that there  is no proprietary, or  incorrect information,  included
in these abstracts.

Additionally, we would like to draw your attention to the abstract
fields  under "quality assurance data" and the EPA definition for
site "characterization - the contaminated site was characterized for
the extent and nature of contaminants present;
representative sampling  - a sampling strategy was designed  that
provided  a statistical  basis  for estimating  the contamination
before and after the remediation activity;
data quality objective process - the objectives for data  quality
were established prior to the  onset of the  study or remediation;
QA/QC conducted - QA/QC steps,  such as audits,  replicate analysis,
calibration of instruments,  and training of personnel,  were  used
in sampling arid analysis; and
peer review -  the report or the data were sent out to  be reviewed
by knowledgeable peers.
These fields have been entered as "Y/N"  (yes/no) on your abstract.
                            accuracy for the database,  these  have
                                If  applicable and, if known, please
