VISITT Profiles 155

Innovative Technologies

VISITT contains information on ven-
dors of innovative technologies to treat
ground water in situ, soils, sludges and
sediments. It includes technologies at all
stages of development—bench, pilot, or
full. Exhibit 1 lists the types of technolo-
gies included in VISITT, and the number
of technologies in  each category, by
status. Based on the information pro-
vided by vendors, nearly 40 percent of
the innovative technologies in VISITT
are commercially available at full scale.
Seventeen technologies treat ground
water in situ,  132 treat soil, 115 treat
sludge, and 94 treat sediments.  123
technologiestreatorganics, VOinorganics
(primarily metals), and 25 treat organics
and inorganics present in the same waste
or media. Exhibit 2 lists the names and
addresses of each vendor in the system
by technology.

The basic information on each technol-
ogy includes the vendor name, address,
and phone number, technology descrip-
tion, highlights, and limitations; and the
contaminant and waste/media treated.
Many of the vendors with technologies
at the pilot and full scale also provide a
summary of performance data, project
names and contacts,  available hardware
and capacity,  unit price information,
treatability study capabilities, and litera-
ture references. Performancedata, project
information, and literature citations can
be used to substantiate a vendor's claims.
        New Database Links Technology Vendor to the
        Remediation Professional
        The U.S.  Environmental Protection
        Agency (EPA) is pleased to announce the
        availability of the Vendor Information
        System for Innovative Treatment Tech-
        nologies (VISITT). This database has
        been developed by the Technology Inno-
        vation Office (TIO) within the Office of
        Solid Waste and Emergency Response
        (OSWER). This is part of abroad effortto
        promote the use of innovative treatment
        technologies for the cleanup of soil and
        ground water contaminated by hazardous
        waste.  VISITT is designed to capture
        current information on the availability,
        performance, and cost of innovative treat-
        ment to remediate contaminated hazard-
        ous waste sites.

        VISnT is available on diskettes compat-
        ible with personal computers using DOS
operating systems. Version 1.0 of the
database contains detailed information
on 155 technologies offered by 97 devel-
opers and vendors. VISITT gives these
companies an opportunity to market their
capabilities, and enables Federal, state,
and private sector environmental profes-
sionals to screen innovative technolo-
gies for application to specific sites.
VISITT also identifies vendors who per-
form treatability studies and provide
cleanup services.

EPA is already preparing for the next
VISITT update (Version 2.0) early next
year. EPA invites all vendors of innova-
tive technology to submit technology
information for this update. Instructions
for submitting information are givenlater
in this bulletin.
        Menu-Driven Design Delivers Flexible, Easy to Use
        Search, View and Print Capability

        VISITT provides environmental professionals with rapid access to up-to-date infor-
        mation on 155 innovative technologies and the 97 companies that offer them.
        VISITT's menu-driven design allows the user to search the extensive technology
        information for particular applications and technology types. The user, for example,
        can enter a waste description to identify innovative technologies in the system that
        treat such wastes. The user can also locate specific sites where vendors may have
        conducted treatability studies or cleanups.

        Once the database identifies the technologies and vendors  meeting the user's
        requirements, the user can then review such information as available equipment,
        performance data, and experience.  Printing options include printing all of the
        technology information for a given vendor, or only those data fields of particular
        interest.
                                                                              Printed on Recycled Paper

Vendors Provide EPA With Up-To-Date Information on
Innovative Treatment Technologies
EPA has designed a questionnaire, the
VISnTVendorlnformationForm (EPA/
540/2-91/011, No. 2), for vendors, sup-
pliers, and manufacturers of innovative
remediation technologies.  Depending
on the technology status, a vendor com-
pletes some or all of the form and sub-
mits it to EPA  for consideration and
review. EPA first reviews the technol-
ogy for eligibility.  The eligible innova-
tive remediation technologies included
in Version 1.0 are listed in Exhibit 1.
Other innovative technologies, such as
pyrolysis, may also be added if they are
submitted in the future. Technologies
not included in VISITT represent estab-
lished treatment technologies for con-
taminated soil and ground water: incin-
eration, solidification'stabilization, and
above-ground water treatment technolo-
gies.

Also not included are technologies appli-
cable only to industrial waste streams,
such as waste minimization methods.

Secondly, EPA reviews the contents of
the form for clarity and completeness to
enhance the usefulness of the information.
Information, such as units of measure-
ment, are standardized as much as possible
to allow comparisons among vendors and
technologies. EPA works with thevendor
to correct any deficiencies prior to loading
the  information in the database.  It is
important to note that submissions are
vendors' claims; EPA does not review or
certify the accuracy or veracity of the
information.

Requirements for the
VISIT! Database

VISITT is offered on a 5 1/4 inch or
3 1/2 inch floppy disk, accompanied by
a user manual. The database requires a
personal computer with at least 640K of
RAM (random access  memory), an
operating system of DOS Version 3.3 or
higher (i.e., IBM or  IBM-compatible),
and three megabytes ofhand disk storage.
The database is compiled, and requires
no other software to operate. VISITT is
compatible with most printers and Local
Area Networks (LANs).  EPA, through
PRC Environmental  Management Inc.,
offers technical assistance to correct any
hardware or software problems  associ-
ated with installing or using VISITT.

EPA is studying the feasibility of offer-
ing VISITT on-line through an existing
electronic bulletin board, such as EPA's
ATTIC (Alternative Treatment Tech-
nology Information Center) or CLU-IN,
TIO' s own bulletin board system. Plac-
ing VISITT on-line would allow more
frequent updates to the system.

             Glossary
             Treatment technologies are processes applied to the treatment
             of hazardous waste or contaminated materials to reduce their
             toxicity, mobility, or volume through chemical, biological, or
             physical means.

             Innovative treatment technologies are those that lack well-
             documented cost performance data under a variety of operating
             conditions.

             Bench-scale or emerging technologies are innovative tech-
             nologies shown to be feasible through the use of bench-top
             equipment in the laboratory. Data from these studies cannot be
             used to scale up the technology to full scale.

             Pilot-scale innovative technologies are those for which avail-
             able equipment is of sufficient size to verify technology feasi-
             bility and establish design and operating conditions for a full-
             scale system.  However, it is not of the size typically used for
             a cleanup.

             Full-scale innovative technologies  are those for which avail-
             able equipment is sized and commercially available for actual
             site remediation.
