“…Similarly, Rashiba (2010) reported that only Oithonidae is represents the sub-order Cyclopoida from Bay of Bengal. Further, Ananthan et al, (2007) also recorded the dominance of Oithona sp in Cuddalore backwater. According to Vineetha et al, (2015), Oithona brevicornis comes under the family Oithonidae, exhibited higher abundance among the Cyclopoids in tropical estuaries of Cochin.…”

“…For instance, in the high altitudes nearer to the origin of the river Ganges, coliform contamination has been noted (Sood et al 2008). The microbial load in the riverine system including catchments and watersheds is found to be an increasing function of several organic and inorganic pollutants contents as has been noted in Gola (Chandra et al 2006), Uppanar (Jonathan et al 2008), and Narmada rivers , India. River pollution monitoring and assessment is essential for understanding the anthropogenic effects and framing strategies for sustainable development.…”

“…The results on the study will provide the preliminary information on the microbial load that may be useful in projecting the strategies required for the appropriate measures for remediation of the river water. A comparison on the pollution level of this river can be made with other rivers of India (Singh et al 2005a(Singh et al , b, 2007aSood et al 2008;Sharma et al 2008;Jonathan et al 2008) and other parts of the globe (Ayotamuno 1994;Djuikom et al 2006;Zheng et al 2008;Wang et al 2008;Moiseenko et al 2008;Chang 2008) which face the problem of contamination and pollution. Apart from these, a projection can be made regarding the possibility of enrichment in the downstream as a consequence of the pollutant levels.…”

An assessment on the water quality parameters coliform including the bacterial abundance from a point source of river Damodar (24 degrees 26(') N and 86 degrees 53(') E), West Bengal, India was carried out during the period of 2004-2007. The site received mining and industrial effluents from the collieries and industries. The water samples collected on a monthly basis revealed the presence of the coliform bacteria Escherichia coli and Streptococcus sp., between 2,600 and 20,000 colony-forming unit/100 ml throughout the study period with peak abundance during the months of September to December, the post-monsoon period. The relative abundance of the two bacterial species was found to be y(E. coli) = 1.41x (Streptococcus) - 8.07 and were positively correlated (r = + 0.868, df = 34). Principal component analysis revealed three factors to clarify for the observed variance of the environmental variables. The mean values of the physicochemical parameters of the river water at the sampling sites were consistently higher than the levels specified by WHO and other regulatory bodies and qualify as polluted water. The presence of the coliform bacteria in these water samples warrants for proper measure to reduce the pollution at the point source and proper remediation strategies to combat contamination in the domestic water usage from river Damodar from this site and downstream.

“…Uppanar River flows towards north along the sea coast at SIPCOT Cuddalore with high salinity due to back waters as well as discharge of industrial and domestic effluents in the historical past (Jonathan et al 2008). The total dissolved solids (TDS) of the river water varied from 26, 507 to 32, 369 mg/l with an average of 28, 870 mg/l (Sankaran et al 2009).…”

This paper deals with a systematic hydrogeological, geophysical, and hydrochemical investigations carried out in SIPCOT area in Southern India to demarcate groundwater pollution and saline intrusion through Uppanar River, which flows parallel to sea coast with high salinity (average TDS 28, 870 mg/l) due to back waters as well as discharge of industrial and domestic effluents. Hydrogeological and geophysical investigations comprising topographic survey, self-potential, multi-electrode resistivity imaging, and water quality monitoring were found the extent of saline water intrusion in the south and pockets of subsurface pollution in the north of the study area. Since the area is beset with highly permeable unconfined quaternary alluvium forming potential aquifer at shallow depth, long-term excessive pumping and influence of the River have led to lowering of the water table and degradation of water quality through increased salinity there by generating reversal of hydraulic gradient in the south. The improper management of industrial wastes and left over chemicals by closed industries has led surface and subsurface pollution in the north of the study area.
