Heterogeneity of sorption and transport-related properties in a sand-gravel aquifer at columbus, Mississippi

摘要

Properties related to sorption and transport of organic compounds have been determined on 126 sections of 17 cores taken in an aquifer at Columbus Air Force Base in Columbus, MS. Each core section was homogenized prior to analysis. Organic carbon content(OC), specific surface area(SA), distribution coefficient(K_d)for naphthalene, and particle size distribution were measured on each section. Hydraulic conductivity(K_h)for each section was calculated from the particle size distributions. K_h values obtained were comparable with those from earlier borehole flowmeter and pulse tracer tests.
