Heavy metals in the soil of 13 villages of Bathinda district, Punjab, India, were measured using wavelength dispersion X-ray fluorescence technique (WDXRF). 29 elements for which these samples were analyzed are U, Th , 40K, Pb, La, Ba, Cs, Ce,, Sn, Sb, As, Cr, Zn, Cu, Co, Sr, Zr, Sc, V, Ni, Rb, Mo,Ga, Nb, Y, Fe2O3, CaO, MnO and TiO2 . Radioactive substances like U and Th are quite low. Alkaline elements like Ca, Ba, Sr are quite high and may be acting as catalysts to low level radioactive elements. As, Fe, Co, Ni, Zr, Cr, Zn too are probably due to proximity of a thermal power plant at Bathinda and use of pesticides and fungicides for plantation.

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.

Chemical Parameters

In the present study, both the underground and surface water samples around Guru Nanak Dev Thermal Power Plant Bathinda, Punjab, having total installed capacity of 440MW, were analyzed for the physico-chemical parameters viz. pH, Electrical Conductivity (EC), Total Dissolved Solid (TDS), Total Hardness (TH), Calcium (Ca2+), Magnesium (Mg2+), Total Alkalinity (TA), Carbonate (CO32-), Bicarbonate (HCO3-), Chloride (Cl-), Phosphate (PO43-), Nitrate (NO3-), Fluoride (F-) and heavy metals such as Cadmium (Cd), Copper (Cu), Lead(Pb), Nickel (Ni) and Zinc (Zn). The correlation coefficients (r) among various water quality parameters of studied underground water samples were calculated. The physical and chemical parameters of groundwater are compared with the drinking water quality standards recommended by Bureau of Indian Standards (BIS) (2012) and World Health Organization (WHO) (2017). On the basis of results obtained in the present study, concentration of Chloride (Cl-), Magnesium (Mg2+), Fluoride (F-) and Total  dissolved solids (TDS) observed in ground water of Bathinda varied from 30 to 284 mg/l, 120 to 280 mg/l, 2.66-3.99 mg/l and 620-1439 mg/l, respectively which are exceeding the acceptable limits prescribed by WHO (2017) as well as BIS (2012). Also, the concentration of heavy metals viz. cadmium (0.366 to 0.437 mg/l), and lead (0.193 to 0.353 mg/l) have higher levels than prescribed by WHO and BIS for drinking purpose. Thus, groundwater is not suitable for drinking purposes with prior treatment.

Initial Slag

A simple and cost-effective method was applied for the synthesis of zeolite composites utilising wet bottom boiler slag from the Bulgarian coal-fired thermal power plant ?Sviloza?, near the town of Svishtov. The method consisted of a prolonged alkali treatment at room temperature of this waste. Experimental techniques, such as scanning electron microscopy, energy-dispersive X-ray and X-ray diffraction analyses, are employed to characterize the initial slag and the final products with respect to their morphology, and elemental and mineral compositions. The composites synthesized in this way contained two Na-type zeolite phases: zeolite X (type FAU) and zeolite Linde F (type EDI). The zeolited products and the starting slag were tested as adsorbents for a textile dye (Malachite Green) from aqueous solutions. In comparison with the initial slag, the zeolite composite possessed substantially better adsorption properties: it almost completely adsorbs the dye in much shorter times. The results of this investigations revealed a new, easy and low cost route for recycling boiler slag into a material with good adsorption characteristics, which could find different applications, e.g., for purifying polluted waters, including those from the textile industry.

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.
