Sorption Of 2-Naphthalene Sulfonate To Organic Carbon In Natural Saturated Porous Media, Jiyan Hatami

Theses and Dissertations

Organic carbon (OC) in aquifer sediments serves as a key geochemical control on contaminant fate and transport, potentially immobilizing or delaying mass transport downgradient. Quantifying the abundance of OC in aquifer sediments is therefore imperative in developing a conceptual understanding of local contaminant transport. Traditional methods involve time-intensive coring and lab analyses for total OC (TOC) at distinct intervals with depth. These methods fail to account for the heterogeneity between discrete points and do not interrogate TOC along groundwater flow pathways. 2-naphthalene sulfonate (2-NS), a novel groundwater tracer, was investigated here as a possible sorptive tracer for estimating the relative …
