The present study focused on the groundwater contamination due to fly ash disposal of coal-fired thermal power plant into a non-liner ash pond. Tendubhata were selected as study site around ash pond of Marwa thermal power plant. Groundwater samples were collected on random basis using composite sampling method. Ten heavy metals (Ca, Cu, Cd, Cl, Zn, Pb, Ni, Cr, Mn, and Fe) were detected in coal, fly ash, and groundwater samples. Heavy metal concentration in coal and fly ash was assessed by Energy Dispersive X-ray Fluorescence, while AAS was used for groundwater assessment. The observed results revealed the exceeding value of heavy metals prescribed by WHO for groundwater.

The study involves evaluation of quality of groundwater and soil near the Thermal power plant located in Udupi District, Karnataka, India based on seasonal variation. 24 samples of ground water and soil were collected during Pre-Monsoon, Post- Monsoon and Monsoon Seasons from the places which are surrounding the Thermal Power plant. Collected Ground water samples were tested for detection of various heavy metal concentrations such as Ni, Fe, Mn, Cr, and Pb and soil samples were detected for Ni, Fe, Mn, Cr, Pb, Cd and Co. Collected soil samples were sieved according to different Standard sieve size. After sieving, soil samples were digested using tri-acids (Nitric Acid, Hydrogen peroxide and Concentrated Hydrochloric acid). Both Ground water and Soil samples were analysed for heavy metal contamination by using Atomic Absorptive Spectrometry. From the results obtained for Pre-Monsoon, Post-Monsoon and Monsoon Season it showed that concentration of heavy metals in the samples were exceeding the permissible limit prescribed by WHO and BIS. Hence preliminary treatment should be done before discharging in to Ash ponds.

The present study focused on the groundwater contamination in pre monsoon and post monsoon status in ten villages near Janjghir Champa district Chhattisgarh state India. Groundwater samples were collected from sites in pre monsoon (April May 2020) and post monsoon (Sept October 2020) using composite sampling method. Ten heavy metals were detected in groundwater samples. The observed results revealed the exceeding value of heavy metals prescribed by WHO for groundwater.

AbstractIn order to assess the quality of groundwater near ash pond of Parichha Thermal Power Plant (Jhansi), heavy metal evaluation index (HEI)was calculated. An unlined ash pond is being used for a long time to dispose fly ash generated by thermal power plant. To assess the level of groundwater contamination due to ash slurry disposal, both groundwater and ash slurry samples were collected and analysed in terms of their chemical concentration. In the present study, it was observed that significant amount of trace elements can leach out from ash slurry and may contaminate groundwater due to downward percolation through soil strata in an unlined ash pond. Obtained results revealed the range of heavy metals concentration in groundwater as [Ni (0.02–0.07 mg/l), Pb (0.14–0.41 mg/l), Fe (0.20–7.21 mg/l), Mn (0.01–0.14 mg/l), Cr (0.03–0.05 mg/l) and Al (0.05–0.26 mg /l)]. HEI showed a heavy load of metal pollution within the range of 5 km from the ash pond while moderate pollution within the range of 7 km and very low at a distance of 15 km.

Naturally growing wild plant species were identified for accumulation of heavy metals at fly ash different disposal sites of Thermal Power Plant Gandhinagar. Cd, Fe, Zn, Cu, Ni, Pb and Cr metals were selected for studying accumulation by indigenous plants. Nine major weed species growing dominantly at fly ash dumpsite were identified i.e. Prosopis juliflora, Ipomea carnea, Calotropis procana, Nerium indicum, Abutilon indicum, Tephrosia purpunea, Cassia tora, Parthenium hysterphorus, Jatropha gossypifolia. Results showed significant accumulation of fly ash heavy metals by indigenous identified plants positive pattern of accumulation differed significantly in different weed species. Roots showed higher accumulation of heavy metals as compared with shoot in most of the plants but in some shoots also showed more accumulation compared to roots. Both translocation factor and bioaccumulation factor was calculated to determine metal translocation from site to roots and from root to shoot. Current results suggest that these plants species can effectively survive in harsh environment and can be used for eco-restoration purpose and also they can be used as potential phytoremediation species.
