Modeling microbial transport and biodegradation in a dual-porosity system

A mathematical model describing microbial transport and growth in a heterog eneous aquifer domain, composed of overlapping subdomains of high-permeabil ity and low-permeability materials, is developed. Each material is conceptu ally visualized as a continuum which occupies the entire considered spatial aquifer domain. Based on the assumption that advection in the low-permeabi lity domain is negligible, the mathematical model is solved by using a publ ically available reactive transport code. The importance of modeling microb ial transport and growth in such a dual-porosity system is demonstrated thr ough a hypothetical case study.
