ABSTRACT
The physico-chemical and
biological (algal and bacterial) quality of tap water in Tanta City were elucidated.
Samples were collected during December
2011, covering all the
water plants and the areal extension of the pipe line network in Tanta. Total dissolved solids content classifies water origin
into surface water, shallow and deep
groundwater. Fe, Mn and hardness
in some samples of groundwater origin are obviously exceeding the WHO (World
Health Organization) limit. Mostly, green
algae are found (31 species), followed by diatoms (19 species), then blue-green
algae (13 species). CCA
(Canonical Corresponding Analysis) indicates that green algae are strongly correlated with pH, NH4,
alkalinity, Mn and Si; diatoms with EC (electric conductivity), turbidity, Zn
and Si and blue green algae with EC and alkalinity. 50% of samples of surface
origin, 80% of samples of both deep and shallow groundwater origins crossed WHO
and Egyptian guideline in their content of mean
TCC (Total Coliform Count). CCA estimates strong
correlations of TCC with temperature, NH4 and PO4; E.
coli with EC; heterotrophic bacteria with turbidity and NO3; Salmonella sp. with Si and SO4 and Pseudomonas aeruginosa with
Mn. Finally, the water plants treatment may be not effective and pipes serve as
a reservoir for pathogenic microorganisms.
