Kirkuk University Journal-Scientific Studies

Abstract

The selection was made on a number of hospitals to conduct a study on the quality of the water. The samples were taken before and after treatment from three hospitals in the city of Kirkuk, Kirkuk General Hospital, Azadi Educational Hospital and Children's Hospital. The samples were collected at regular intervals Six months from September (2016) to February (2017) . The first phase, which included the measurement of some physical variables and chemical variables, included physical measurements, temperature measurement, electrical conductivity (EC), total dissolved solids (T.D.S), (T.S.S), all of which were above the permissible limit, except for the temperature. Chemical analyzes included (pH), (BOD) and (COD),(SO4-2), (PO4-3) and(NO3). The results of the study indicated that the applications were characterized by the rise of most chemical standards, most of which exceeded environmental determinants except (SO4-2) , and (pH), within the limits allowed for Iraqi specifications, and the second phase of the study, to demonstrate the extent of contamination of heavy elements, and included the measurement of the study of heavy elements: (Fe, Cd, Cr) The availability of cadmium and chromium, at concentrations higher than is permitted, while the concentration of iron elements was less than the limit allowed globally and locally, and the study used the research method And statistical analysis of data from wastewater models studied
