Groundwater assessment The collected

The presence of Pb in the leachate samples are in the range 1.85–5.15 mg/L. The possible source of lead may be batteries, chemicals for photograph processing, older lead-based paints and lead pipes disposed at the landfill, which indicates toxicity to all forms of life at this level. Acidity in the leachate causes lead to be released from refuse (Al-Yaqout 2003). Cd (1.4 mg/L) and Cu (1.92 mg/L) are also present in the leachate samples whereas high Mn (8.18 mg/L) concentrations suggest a strong reducing environment. A variety of waste is dumped at  


Groundwater assessment The collected groundwater samples in and around the dumping site were free from color and odor excluding the locations W3 and W12. The groundwater of the studied area is used for drinking and domestic purposes. Table 3 shows the desirable and maximum permissible limit of individual species for drinking water recom- mended by Bureau of Indian Standards (BIS 1991) and World Health Organization (2002).

Syndrome’’. This disease particularly affects infants that are up to 6 months old (Kapil et al. 2009). The presence of TOC values ranges from 2.7 to 49 mg/L indicates that the groundwater contains organic impurities. The concentra- tion of Fe in the groundwater samples varies from below detectable limit (BDL) to 5.102 mg/L (Fig. 5) and was found to be well above the WHO permissible limit (0.3 mg/L) in all the samples. Presence of Fe in water can lead to change of color of groundwater (Rowe et al. 1995).

The contour diagrams show (Figs. 6, 7, 8, 9, 10) the concentration profile of heavy metals at several water sample locations near the study area. The contour diagrams were drawn by surfer software. The collected groundwater samples were analyzed for heavy metals such as Cd, Cu, Mn, Pb, and Zn. Cadmium concentrations in the collected groundwater samples are lower than that of the leachate.
