Abstract

The purpose of this study is to evaluate the presence of microbes on groundwater of Cuddalore District. Groundwater is slowly contaminated by sewages, agricultural and urban runoff. Domestic waste waters are widely discharged to water bodies, particularly rivers. Pathogens related with these discharges consequently become distributed through the water body presenting a risk to downstream water users. Usually municipal raw sewage can contain 10 to 100 million coliform bacteria 100/ml and 1 to 50 million Escherichia coli or faecal streptococci 100/ml. Different levels of wastewater treatment may reduce this by a factor concentrations are reduced further after dilution by the receiving waters. Microbes such as coliforms, streptococci, presence on groundwater were analyzed by using most probable number (MPN) and compared with water quality standard of World Health Organization (WHO).
