Abstract
Abstract In spite of existing a number of thermal springs in Iraq. A limited studies were observed to be found concerning it. Where there are a little information concerning their types of organisms. The present study is an attempt to expand springs water characteristics and algal occurrences. Monthly variations in physico-chemicals variables and algae were studied in Mersaid and a Jale springs from July-2007 to February-2008. It was found that water temperature ranged from 24 to 35C°. Minimum value of pH was 6.9 and maximum value of electrical conductivity is 1350µs.cm-1.Oxygen concentration was zero. No significant variations are found in the alkalinity and total hardness during the period of study. Calcium and sulfate ions are the dominant cations and anions respectively. It was found 22 taxa of algae identified, dominant by cyanophyta.
