MtBE Treatment Profiles:
A New Website on MtBE Treatment Technologies
EPA has prepared profiles of drinking water and
remediation sites that treat soil and groundwater for
methyl tert-butyl ether (MtBE). The MtBE profiles are
accessible at http://clu-in.org/products/mtbe.
What is MtBE and why is it of concern?
MtBE is an oxygenate and an
octane booster that has been
added to gasoline. When
gasoline leaks or spills, such as at
a service station with leaking
underground storage tanks, soil
and groundwater may become
contaminated with MtBE. Such
contaminated media poses risks to
drinking water supplies and the
environment.
Why develop a website with MtBE treatment profiles?
Site managers need site-specific data to help select
appropriate treatment approaches at remediation sites
and for drinking water contaminated with MtBE.
What types of data does this website contain?
Profiles on the website contain data on completed and
ongoing applications of treatment for MtBE in drinking
water and contaminated media. As of March 2002,
the website included 244 MtBE treatment profiles.
What types of information does a profile provide?
A profile describes the use of in situ and ex situ
technologies to treat MtBE in groundwater, soil, and
drinking water at specific sites. Each profile has a
varying level of detail, depending on the data and
information that was available. Some of the profiles
include active links to more detailed case studies, which
present in-depth information about the treatment sites.
What specific information does a profile provide?
Each profile contains the following information, as
available:
4 Project information
- Site background and setting
- Contaminant(s) and media treated
- Area of contamination and quantity treated
4 Technology design and operation
4 Cost and performance information
- Cleanup goal and performance information
- Cost for remediation
4 Point(s) of contact
4 References

What data sources were used to develop this website?
To prepare the profiles, EPA obtained data from site
managers, regulatory officials, and technology
providers, as well as published reports, conference
proceedings, and other available reference materials.
How can I search the website?
The website can be searched in two ways - using a
pick list for selected parameters or using the list of all
available profiles. The website includes pick lists for
contaminant, media, technology, scale, status, state,
and site name. Search results are listed alphabetically
by site name.
Where are the full case studies on the website?
Profiles that have more detailed case studies (in pdf -
format) are identified on the results page. The results
page will indicate that a case study is available and
provide a direct link to that case study.
How can I submit a new profile or update an existing one?
EPA encourages project managers, site owners, and
technology vendors to update existing MtBE treatment
profiles or add new profiles to this website. A user may
select the "Update an MtBE Treatment Profile" button to
add more recent data, add data for more fields, or
correct errors in existing data. A user may also submit
a new profile by selecting the "Submit a New MtBE
Treatment Profile" button. Information submitted
through the website is reviewed by EPA prior to being
made available to the public.
-------
What are the future plans for this website?
EPA is actively seeking additional MtBE treatment sites and preparing additional profiles and links to detailed
information on MtBE cleanups.
How can I provide feedback/comments on this website?
Send your feedback and comments to Linda Fiedler of EPA's Technology Innovation Office, by e-mail at
fiedler.linda@epa.gov or phone at (703) 603-7194.
Where does EPA provide additional information about MtBE?
