MICROBIAL AND PHYSICOCHEMICAL EVALUATION OF GROUNDWATER RESOURCES FOR HUMAN DOMESTIC CONSUMPTION IN ALFATH URBAN, ASSUIT, EGYPT

Sewage is the primary source of faecal contamination of groundwater with pathogenic bacteria. Protecting groundwater
from microbial contamination is a top public health priority, This study deals with evaluation of groundwater wells, ground
water well based-plants, in Alfath lying in Eastern area of Nile Basin, Assuit at summer 2014 with assessment of presence of
thermotolerant faecal coliform and thermotolerant faecal streptococci bacteria as a potent indicators for faecal contamination,
we used a multiple-tube fermentation or membrane filtration for enumerating themotolerant faecal coliform and thermotolerant
faecal streptococci using most-probable-number (MPN) index. This study consisted of a total of 75 water samples obtained
for routine testing at summer 2014, there are 5 water wells not suitable consuming as drinking water for human, 3 expulsion of
water well plants (Alfath-Alkadema, Bani-Talib and Arab-Moteer) need to sterilization or replacement and renovation. Physicochemical
parameters were determined for these water samples.
