Abstract

Riverbank filtration (RBF) systems are often used to treat surface water near rivers. The
effectiveness of such systems depends heavily on the properties of the riverbank material that is used for
filtering and treating the water. To improve the system’s treatment efficiency, modifications may be
conducted to the riverbank soil. Altering the properties of the soil might, however, affect the stability of the
riverbank. In this study, soil and water samples near Lake Chini were collected and characterized. Filtration
test was conducted to evaluate the efficiency of the soil in treating the water. The soil was modified by
mixing it with powdered activated carbon (PAC) at varying percentage of 5 and 10%. In addition,
compressibility test was carried out using a standard oedometer. Test results indicated that the soil alone was
insufficient to treat the water to drinking water quality standards. Modification with activated carbon
improved the water quality from Class II to Class I. However, compressibility test revealed that there were
some changes to the pressure - void ratio relationship, indicating that the alteration of soil properties with the
addition of activated carbon filters might affect the stability of the riverbank.
