Physicochemical, Metal and Microbial Analysis of Sago Industry Effluent and nearby Ground Waters to Assess the impacts of Effluent on Ground waters


Water sources near Industrial areas are generally exposed to pollution due to the effluents generated from the industrial units. Sago industry is a small scale industry and also a seasonal industry operating from September to March in East Godavari District. The washed residue of sago when released in to the nearby streams along with waste water can cause serious environmental problems. The present study is aimed to characterize the effluent and ground water for physicochemical parameters viz., pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS),Total Hardness(TH), Total Alkalinity(TA), Na+, K+, Ca2+, Mg2+,Chloride,Sulphate,Nitrate and Phosphate around the industry to assess the impact of effluent on ground water. The irrigation parameters like Percent Sodium (%Na), Sodium Adsorption Ratio (SAR), Residual Sodium Carbonate (RSC), Kellys’s Ratio (KR) and Magnesium hazard MH are determined to assess the suitability of waters for irrigation purposes. Metal ions viz.,Li, Be, Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Ag, Cd, Cs, Ba and Pb are characterized to assess the metal ion contamination .The higher values of EC, TDS, TA, Na, Chloride indicate the contamination of ground waters in the study area. Higher values of Magnesium Hardness indicate the (MH)of water which in turn deplete the quality of soil and consequently the crop yield will be reduced, if the waters are used for irrigation purposes. The lower metal ion concentrations indicate that the waters are free from metal toxicity. The water samples are also tested for MPN count and analyzed for identifying the bacterial species. Presence of pathogenic bacterial species viz., E.Coli, Enterobacter, Klebsiella and Pseudomonas indicate the bacterial contamination of waters and the waters can cause concern on human health, if consumed for drinking purposes. The waters are to be treated properly to protect the health of the public residing in the nearby habitations of the sago industry who consume these waters for drinking and domestic purposes.
