Algal Composition and under ground water quality for some artesian wells in Al-Rrehba region - South of Bahr Alnajaf - Iraq

Abstract

The present study was conducted about some physical-chemical proprieties and algal composition in
two artesian wells in Al-Rehba region south of Bahr Alnajaf \Iraq from Novmber-2007 to April-2008.
The results showed that water quality of the studied Artesian walls tend to be slightly alkaline, hard,
and has overcritical Oxygen.
Statistical analysis doesn't show any significance differece between physical-Chemical proprieties of
studies wells except in electrical conductivity(E.C) in April 2008.About36 Algal taxa has been
classified in this study. Diatom(Bacillariophyceae) was the most dominant Algae (86.1%) followed by
Blue green (Cyanophyceae) (13.9 %).
