  • Quantified heavy-metal contamination across groundwater, surface water, soil and sediment of the Hooghly estuary, and compared it against WHO drinking-water and soil standards.
  • Found arsenic in surface water and groundwater, and manganese in groundwater, above WHO limits (0.01 mg/L As, 0.05 mg/L Mn).
  • Assessed sediment toxicity and ecological risk with the geoaccumulation index, potential ecological risk index and toxic risk index.
  • Used correlation analysis to study how surface-water and groundwater contamination influence each other.
