Abstract
Some physical and chemical factors that effect drinking water quality have been studied in the old and new water purification stations in AL-Khalis District , Diala Governorate from the beginning of January to December 2009 . The ( pH ) results showed that it's in the weak alkaline for both stations during all the months of the year. Its least ratio ( 7.4 ) was recorded in the old station in July and September , Whereas the new station recorded the most ratio ( 7.8 ) for some months . The total dissolved solids quantity showed that it is in the permitted ratio of the drinking water . The new station recorded high ratio compared the ratio of the old station , It recorded ( 418 ) ppm for some months of the year whereas the old station recorded ( 332 ) ppm in September . The electrical conductivity results showed that they increase by the increase of the total dissolved solids in both stations . The concentration of the dissolved oxygen recorded high ratios in both stations ( 8-12 ) ppm , And its highest ratio was recorded in the new station . The total hardness showed that the studied water samples are in hard water degree in all months of the year . The new station recorded the highest ratio ( 366 ) ppm in March , Whereas the old station recorded the lowest ratio ( 215)ppm in June . The elements that cause hardness from magnesium and calcium concentrations showed that the highest ratio of calcium was in the water of the new station , It recorded ( 84 ) ppm in November . Whereas its highest ratio was recorded in the old station (48.3) ppm in July . The ratios of magnesium concentration showed that they were universal with the ratios of calcium concentrations . Water Turbidity was in accordance for some months( Turbidity < 5 NTU ) ( Nephelolometric Turbidity Unit) and not in accordance with the permitted qualification for the other months ( Turbidity > 5 NTU ) Compare with a large extent of the months of the year .
