Oxalate extract concentrations have been used to provide an upper estimate of the amount of labile As in the sediments. Due to the similar desorption patterns of arsenic as arsenate and fluoride from Fe hydr oxides with respect to the pH increase, it is quite reasonable to infer the co-contamination of the above anions in the oxidizing aquifers Bhattacharya et al.
