Abstract This study was inspired by the Klang Valley water crisis, for which bank infiltration (BI) is considered a potential solution. This paper presents a case study of the BI techniques, which evaluates the effects of groundwater pumping and BI operation on the installation of wells. This study also determines the effect of pumping rate on flow paths, travel time, the size of the pumping and capture zone delineation, and groundwater mixing in a pumping well in Jenderam Hilir, Malaysia. The proposed method performs infiltration safely and achieves the ideal pumping rate. Numerical modeling packages, MODFLOW and MODPATH (particle tracking) were used. Results indicate that the migration of river water into the aquifer is generally slow and depends on the pumping rate and distance from well to the river. Most water arrives at the well by the end of a pumping period of 1 to 5 days at 3,072 m3/day for test wells DW1 and DW2, and during simultaneous pumping for DW2 and PW1 for a well located 36 and 18 m, respectively, from the river. During the 9.7-day pumping period, 33 % of the water pumped from the DW1 well was river water, and 38 % of the water pumped from DW2 throughout 4.6 days was river water. M. K. N. Shamsuddin : S.

Introduction Sustainable groundwater resource management through induced bank infiltration (BI) is an alternative surface water treatment method. The BI system near rivers is utilized in water resource management to increase both water quantity and quality. It is also used to obtain safe drinking water supply from the river. The BI method helps prevent problems caused by pollution without the need for additional chemical treatment because some suspended and dissolved contaminants from the surface water are treated or reduced through aquifer materials. Therefore, BI is an effective, inexpensive, and sustainable means that allows water supply utilities to ensure high water quality. Compared with surface water, groundwater is typically a higher quality source and requires less treatment. However, in many areas, groundwater
