Abstract

The objective of this study was to investigate the removal and transformation of dissolved organic matter (DOM) through laboratory-scale soil aquifer treatment (SAT) soil columns. Using XAD resins, DOM was fractionated into 3 fractions: Hydrophobic acid (HPO-A), transphilic acid (TPI-A) and hydrophilic fraction (HPI). Laboratory-scale SAT columns reduced about 58.64%, 41.86% and 68.51% of HPO-A, TPI-A and HPI, respectively. All samples studied exhibited a common general relationship with respect trihalomethane formation potential (THMFP): HPO-A > HPI > TPI-A. Specific ultraviolet light absorbance (SUVA) and specific trihalomethane formation potential (STHMFP) values for various DOM fractions increased across the SAT columns. HPI exhibited greater increase in SUVA and STHMFP than HPO-A and TPI-A. The STHMFP of HPO-A was greater than that of corresponding TPI-A and HPI fractions in all samples.
