Push-Pull Tests & PPTEST

PPTEST is a multi-species, radial coordinate reactive tranport model to estimate biogeochemical rates and aquifer physical parameters based on a variety of single-well injection-withdrawl (or push-pull) tests. The code is general and allows the user to simulate microbial processes, arbitrary reaction order kinetics, sorption and reaction lag times to test different hypotheses about chemical and biological processes operating at field sites. The Fortran source code, comparisons with field data and analytical solutions as well as input files and sample output are included in the user manual below. The files can be extracted from the manual by double-clicking on the paper-clip icon in section 5 of the manual (also available as a windows zip file in the second link below).
