  1. All concentrations in mg/L. Missing values correspond to concentrations below detection. Detection limits reported in [12]. DIC not measured for May 2012 samples, so charge imbalance error (CIB) not calculated
  2. Salinity calculated from specific conductivity (SpC) using calculator at http://www.chemiasoft.com/chemd/salinity_calculator, after Standard Methods for the Examination of Water and Wastewater, 20th edition, 1999
  3. Specific conductivity values that exceed the Bangladesh Government guideline of 2 mS/cm and arsenic concentrations that exceed the World Health Organization guideline of 0.01 mg/L are italicized
  4. Water types: FP freshwater pond, RP rice paddy, SP shrimp pond, TC-Oct. tidal channel October, RW rainwater
