Abstract

Groundwater quality depends on many things, one of which is the condition of the rock lithology. To determine the quality of groundwater, a geological survey and mapping were carried out through interpretation of the outcrops found in the field; then several groundwater quality parameters were measured and analyzed. This study aims to determine the quality of groundwater by analyzing the parameters of nitrate, phosphate, total dissolved solids (TDS), temperature, pH, turbidity, chloride, manganese (Mn), iron (Fe), and electrical conductivity (EC). The groundwater quality parameters were weighted and calculated using the National Sanitation Foundation Water Quality Index (NSF-WQI) method. Geologically, the groundwater aquifer in the study area exists in an alluvium unit with a coastal alluvial sediment type of aquifer system confined with Ca-HCO3 and Mg-SO4 facies aquifer. Meanwhile, groundwater quality is categorized as moderate, good, and excellent. The moderate category was TSB 6, the good category was TSB 1, TSB 7, and TSB 8; while the excellent category was at TSB 2, TSB 3, TSB 4, TSB 5, and TSB 9. © 2021, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma.
