DISTRIBUTION OF HEAVY METALS (CD AND PB) IN SOIL AND ITS IMPACT ON GROUNDWATER IN BANDUNG REGENCY
This study examined Cd and Pb concentrations in 96 soil and 32 groundwater samples across 7 districts in Bandung Regency using statistical methods. Soil samples were collected within 10 meters of groundwater sampling points at depths of topsoil (10-20 cm), subsoil (50-60 cm), and subsoil (90-100...

| Summary: | This study examined Cd and Pb concentrations in 96 soil and 32 groundwater
samples across 7 districts in Bandung Regency using statistical methods. Soil
samples were collected within 10 meters of groundwater sampling points at depths
of topsoil (10-20 cm), subsoil (50-60 cm), and subsoil (90-100 cm), each with 32
samples analyzed by ICP-OES. Statistical analysis with SPSS assessed Cd and Pb
contamination potential from soil to groundwater. Results showed Cd and Pb
contamination in Bandung Regency soils. Cd concentrations were highest in subsoil
(50-60 cm) > subsoil (90-100 cm) > topsoil (10-20 cm), while Pb was highest in
subsoil (50-60 cm) > topsoil (10-20 cm) > subsoil (90-100 cm). Cd concentration
averaged 6.8535 mg/kg, higher in residential soils (95% CI = 6.115 - 7.591, p <
0.005). Pb concentration averaged 18.551 mg/kg, also higher in residential soils
(95% CI = 14.626 – 22.475, p < 0.005). Pb showed potential contamination to
shallow groundwater in depth ? 6 m with a correlation of 0.903 (p = 0.000 < 0.001)
and a hazard level of 1.01. No significant correlation was found between Cd in soil
at depths up to 1 m and groundwater |
