This study has achieved to determine the concentrations of inorganic chemical metals for raw
and clean water of Baquba liquefier station (the largest unit which provides the city with
drinking water) by taking water samples from the station through (April 2009) till (February
2010), these analysis included the estimation of pH, electrical conductivity, total dissolved
salts, total hardness, calcium, magnesium, chloride, sulfate, sodium, potassium and aluminum.
The clean water results has compared with the world health organization standards to
determine any access in these metals concentrations that are anticipated to produce adverse
health effects following long-term exposure.
All the final results of water samples reinforce the fact that has accepted chemical and
physical properties except turbidity, with simple difference in some chemical concentrations
all over the experimental period, as well as, it is observed that there is no any qualitative
treatment of total hardness for raw water in the station.
Also, the statistical analysis emphasize no significant differences between raw and clean
water except turbidity with the presence of significant differences for most parameters all over
months with significant positive relation between water temperature and both turbidity and
total dissolved salts and negative relation between total dissolved salts and the raining rates.
