STUDY ON THE ENVIRONMENTAL CHARACTERISTICS OF THE WATER OF THE TANKS OF SOME SCHOOLS IN TIKRIT, IRAQ

Salma Khaled Yassin and Yassin Hussein Owaid

Abstract

The current study included the identification of some physical, chemical and biological characteristics of water reservoirs of Tikrit from January 2018 to April 2018. And compare the results with the standards of Iraqi and global drinking water. Bimonthly samples were collected from each plant for four months and eight samples during the study period. The evaluation included the study of the following physical and chemical factors (air temperature, water temperature, electrical conductivity, salinity, total hardness, calcium titration, magnesium titration, total alkalinty, total acidity and chlorides. The results showed that the air temperature ranged between (15-30.1) m while the temperature of water between (12-26.4) m. Electrical conductvity values ranged between (7.0-8.10), salinity ranged between (0.230-0.400) mg/l. The dissolved oxygen values ranged between (5.0-11.9) mg/l while the biological requirement values ranged from (1.1-7.5) mg/l total fermentation ranged from (128-127) mg/l, which resulted from calcium carbonate ranged between (100-170) mg/l while magnesium carbonate ranged between (20.2-84.0) mg/l and basal ranged between (22-80) mg/l and acid values ranged between (4-124) mg/l.
