Abstract: Clogging in porous media is a problem in environmental engineering, hydrogeology, soil science, and petrology. However, a comparison of the literature reveals qualitatively different clogging behavior in different porous ...

Abstract: Engineered injection and extraction (EIE) is a method of in situ remediation of contaminated groundwater in which a treatment chemical that reacts with the contaminant is injected into the contaminated aquifer, and a series ...

Abstract: A rapid, visual evaluation technique has been developed to rank contaminant transport potential at potential release sites (PRSs) at the Los Alamos National Laboratory (LANL). The so-called “matrix approach” is used to ...

Abstract: From a hydrologic perspective, one limitation of pervious concrete pavement is the risk of clogging, defined as a reduction in hydraulic conductivity that reduces infiltration into the pavement or exfiltration into the ...

Abstract: During in situ groundwater remediation, reactions occur in a narrow reaction front in which the amendment and contaminant are close enough to mix. Active spreading, in which injection or extraction wells create spatially ...
