| A total of i50 water sarnples examination in Kirkuk province were carried out using directdeposit examine microscopically, study parameters involves four type of water collections : direct (governmental pipes), indirect ( tank vehicle) ,well water & river water ( Khasah Sou),which divided in to four positions. The main aims of this study are to detect role of parasiticstages in contamination of water in Kirkuk Province & to assess the relationship betwein watercontamination with protozoa & some water quality tests like (pH, TurblOity A chlorinepercentages). The result of the study shows all rate of contamination i4%, which divided intoL2 % & 2 o/o in urban arca & rural area respectively ,P<0.05. River water shows high rate ofcontanrination 12 o/0, followed by 1.33 % &0.66% from direct (Governmental pipei) & wellwater respectively P<0.05.The rate of water turbidity was 10.66 % with high occunence in riverwater 5.33 % & the lowest rate 0.66Yo was in wells. P<0.05.Abnormal chlorine percentage wasseen in 6-water sample with.the rate 4 % P>0.05. Abnormal PH of wate, ,*p1., were iangedfi'om 5.23 to 10.3 which had no role in frequency of parasitic forms in water, p<0.05.The morecommon parasitic forms that found are Entamo eba hiitolytica thatwas highly dominated in riverwater 12 o/o followed by Giardia lamblia 3.22%. Other microorganisms ttrut *" isolate includeCandida species 12,6 % and Paramecium I2Yo. Total rate of water contamination withnricroorganisms is 42 %. |
