total of 7265. If you're just joining us, welcome. We try to keep this
as brief as possible, but provide information relevant to your needs.
Your feedback is most welcome.
Mention of non-EPA documents does not constitute a U.S. EPA
endorsement of their contents, only an acknowledgment that they
exist and may be relevant to the TechDirect audience.
This month, by happenstance, most of the documents highlighted
deal with remediation and characterization of groundwater.
Documents
Groundwater Cleanup: Overview of Operating Experience at 28
Sites (EPA 542-R-99- 006). This report was published by the U.S.
EPA Technology Innovation Office. It compiles information from 28
case studies of groundwater cleanup systems, including 26
pump-and-treat systems (P&T), 2 permeable reactive barriers, and 1
site where a reactive barrier replaced a P&T system. In situ
bioremediation and air sparging are also used in conjunction with
several of the P&T systems. [The full 28 case studies, as well as 112
other studies are available at httnv/www.frtr.gov under Cost and
Performance.] This report is divided into sections dealing with site
characteristics; system design and operation; performance; cost and
factors affecting performance and cost [September 1999, 66 pages].

Reliability-based Uncertainty Analysis of Groundwater
Contaminant Transport and Remediation (EPA 600-R-99-028).
This report was published by the U.S. EPA Kerr Environmental
Research Center. It presents a probabilistic modeling tool based on
first- and second-order reliability methods to account for parameter
uncertainty in ground water transport and remediation. The
methodology is applied to analytical ground water models to provide
a simple screening tool for the assessment of contamination and
remediation [June 1999, 82 pages]. View or download at

water contaminated with restricted RCRA hazardous wastes, which
is extracted during a RCRA corrective action or CERCLA response
action, must meet the best demonstrated available technology
(BDAT) identified for that waste under the RCRA land disposal
restrictions (LDRs) prior to each reinjection, in a pump-and-treat
reinjection remediation system. This memorandum explains EPA'S
interpretation of whether the LDRs are applicable or (under CERCLA
response actions only) relevant and appropriate to such reinjections
or to the remediation as a whole [December 1989, 3 pages]. View or

Free-product Recovery of Petroleum Hydrocarbon Liquids. This
manual, produced by the American Petroleum Institute, is useful for
evaluating remediation options at sites where free product is present
at the water table of an unconfined aquifer or perched on a confining
bed. The manual reviews the basic principles of lighter-than-water
nonaqueous phase liquid flow in porous media. Physical/chemical
parameters that are essential in the design and analysis of
free-product recovery systems are discussed. An overview of
remediation technologies associated with free-product recovery is
provided. This includes basic design information and the relative
merits of each method. The manual provides and explains equations
and nomographs for determining recovery rates, total volumes
recovered, and recovery times. In addition, two computer
spreadsheets are available to implement the calculations described
in this document. View or download at http://www.api.org/ehs/fpr/4682rh.htm . Hard
copies are available for $55 from API's Publications Department

List of Leak Detection Evaluations for Underground Storage
Tank Systems - Sixth Edition (EPA 510-B-99-004). This
publication was updated and reissued by EPA Office of Underground
Storage Tanks. The list is based on reviews by the independent
National Workgroup on Leak Detection Evaluations consisting of
state and EPA UST program staff. Therefore, this list is not an EPA
