The current study was aimed to find out the heavy metal concentration of groundwater in the Veppanthattai block. Here, 45 water samples from different sites were collected during the year 2015 at post monsoon, and Cd, Cr, Cu, Fe, Ni, Pb and Zn heavy metal content was analyzed using an atomic absorption spectrophotometer (AAS), The obtained results were then compared with the WHO standard for the specific highest pollution level. Accordingly, some or all water samples are above the permissible limit, particularly for Cd metal (all samples). The elevated concentration of cadmium in water samples of the study area may be due to agricultural runoff, as pesticides and cadmium-containing fertilizer have been used. The study showed that without proper treatment, the groundwater of the study area is not suitable for domestic applications.

The present work measures the adsorption capacity of sugarcane bagasse to remove excess lead from groundwater. Batch adsorption experiments were carried out to evaluate the adsorption equilibrium, and the effects of four parameters (pH, adsorbent dosage, equilibrium time and particle size) on the adsorption of lead were investigated. Characterization of the adsorbent was carried out through SEM and FTIR instruments. Results confirm that the adsorption of lead takes place successfully on the surface of the adsorbent. The maximum efficiency of adsorption is up to 50% achieved in 5g adsorbent dosage, at an optimum pH 5, with a contact time of 120 minutes and 53 μm adsorbent size at 38.
