The QTRACER2 Program for Tracer-Breakthrough Curve Analysis for 
Tracer Tests in Karst Aquifers and Other Hydrologic Systems; and A 
Lexicon of Cave and Karst Terminology With Special Reference to 
Environmental Karst Hydrology

AGENCY: Environmental Protection Agency.

ACTION: Notice of availability of two final reports and CD-ROMs.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of two final reports, 
The QTRACER2 Program for Tracer-Breakthrough Curve Analysis for Tracer 
Tests in Karst Aquifers and Other Hydrologic Systems (EPA/600/R-02/001, 
May 2002, which supercedes EPA/600/R-98/156a and 156b, February 1999), 
and A Lexicon of Cave and Karst Terminology with Special Reference to 
Environmental Karst Hydrology (EPA/600/R-02/003, February 2002, which 
supercedes EPA/600/R-99/006). These reports were prepared by the U.S.

Environmental Assessment (NCEA) of the Office of Research and 
Development (ORD).
    The QTRACER2 Program for Tracer-Breakthrough Curve Analysis for 
Tracer Tests in Karstic Aquifers and Other Hydrologic Systems is a 
detailed users manual with a CD-ROM. QTRACER2 takes basic input data 
obtained at the start and finish of a hydrologic tracer test and 
performs the basic calculations (e.g., numerical integrations necessary 
for extracting critical hydraulic and geometric information about the 
flow system under investigation). The executable code, source code, 
additional related programs, and several example data files are all 
contained on a CD-ROM. QTRACER2 is an update of the previously released 
QTRACER to run under Windows with considerable mouse support, including 
some minor bug fixes and expanded analysis capabilities. For example, 
short- and long-term pulse tracer releases and continuous tracer 
releases can now be adequately addressed by QTRACER2.
    A Lexicon of Cave and Karst Terminology with Special Reference to 
Environmental Karst Hydrology is a substantial listing and cross-
referencing of major and minor karst-related terminology. This updated 
version contains some corrections to the previous version and includes 
numerous biological and ecological terms that were not included in the 
original release. It includes numerous foreign terms because so much of 
the literature is developed in other countries and often published in 
somewhat unknown journals.

DATES: These documents will be available November 27, 2002.
