A Study of the Physical and Chemical Features of Three Well Water in Kirkuk City and Determining their Algal Content

Abstract

The present study was conducted about some physical-chemical properties and algal composition in three artesian wells in Kirkuk city Iraq from November-2010 to jun-2011. The results showed that water quality of the studied artesian wells was characterized by an increase of electrical conduction and chloride ions therefore it causes the land to be salty ,but it can be used for irrigation in soils with high light transmittance and for agricultural crops resistant to salinity moreover it showed that it contains Oxygen above critical standard . Statistical analysis doesn't show any significance difference between physical and -chemical properties of studies wells in study period. About 37 Algal taxa have been classified in this study. Diatoms was the most dominant Algal (56.756%) followed by (Chlorophyceae) ( 16.216%) then followed by Blue green Algae (Cyanophyceae) (13.513%) then followed by (Euglenophyceae) ( ( %8.108 ) at last followed by ( Dinophycea ) ( 5.405%) .
