Effluent fluid electrical conductivity and early time\u00a0\u03c3b\u00a0were modeled according to classic advective-dispersive transport of the nutrient medium. However,\u00a0\u03c3b\u00a0along the column exhibited strongly bimodal breakthrough which cannot be explained by changes in the electrical conductivity of the pore fluid. We model the anomalous breakthrough by adding a conduction path in parallel with the fluid phase, with a time dependence described by a microbial population-dynamics model. We incorporate a delay time to show that breakthrough curves along the column satisfy the same growth model parameters and offer a possible explanation based on biomass-limited growth that is delayed with distance from influent of the nutrient medium. Although the mechanism causing conductivity enhancement in the presence of biomass is uncertain, our results strongly suggest that biogeochemical breakthrough curves have been captured in geoelectrical datasets.", "description": "L14402; 5 p.", "publisher": { "@type": "Organization", "name": "AGU" }, "author": [ { "@type": "Person", "name": "Day-Lewis, Frederick D. daylewis@usgs.gov", "givenName": "Frederick D.", "familyName": "Day-Lewis", "email": "daylewis@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0003-3526-886X", "url": "https://orcid.org/0000-0003-3526-886X" }, "affiliation": [ { "@type": "Organization", "name": "WMA - Earth System Processes Division", "url": "https://www.usgs.gov/mission-areas/water-resources" }, { "@type": "Organization", "name": "OGW Branch of Geophysics", "url": "https://www.usgs.gov/mission-areas/water-resources" }, { "@type": "Organization", "name": "Office of Ground Water", "url": "https://www.usgs.gov/mission-areas/water-resources" } ] }, { "@type": "Person", "name": "Yee, N.", "givenName": "N.", "familyName": "Yee" }, { "@type": "Person", "name": "Ntarlagiannis, D.", "givenName": "D.", "familyName": "Ntarlagiannis" }, { "@type": "Person", "name": "O'Brien, M.", "givenName": "M.", "familyName": "O'Brien" }, { "@type": "Person", "name": "Slater, L.D.", "givenName": "L.D.", "familyName": "Slater" } ], "funder": [ { "@type": "Organization", "name": "OGW Branch of Geophysics", "url": "https://www.usgs.gov/mission-areas/water-resources" }, { "@type": "Organization", "name": "Office of Ground Water", "url": "https://www.usgs.gov/mission-areas/water-resources" }, { "@type": "Organization", "name": "Toxic Substances Hydrology Program", "url": null } ] }
