Multivariable statistical approach were applied to evaluate groundwater quality in Jisser Diyala area, this technique was used to find the relation between physco-chemical properties of water and pattern of changing the groundwater quality in this area. Cluster and Factor analysis were applied in two type R-mode and Q-mode to identify the grouping of chemical properties and identify the factors controlling the change in quality.

Several soil samples 36 were collected from different areas (residential, industrial, commercial, major roads and agriculture) to investigate some heavy metals concentration (Pb, Ni, Cr and Cd) and their geographical distribution inside Waist city one sample has been selective for each area with depth 0-30 cm. Results showed that there is a differences in the level of accumulation in some of the soils, particularly with Lead and Nickel, which was probably caused by human activities. The increase of elements concentration (Pb, Ni, Cr and Cd) are associated mostly with industrial areas, locations where sewage water are released and points were household waste are disposed. Concentration averages of (Pb, Ni, Cr and Cd) in collected soil samples from waist province residential areas recorded 38.9, 46.9, 59.1 and 0.231 mg kg -1 respectively. Meanwhile, the rates of same metals in the industrial areas soil were 1432 ,

The interaction between surface water represented by Tigers River, Fish Lake, drainage and groundwater was examined in this study. Samples were collected from Al-Azezeyia city for stable isotope (2H and18O). Samplings of water were taken during January – September 2016 during the period of breeding fish. Two samples were taken from a fish lake, three samples from Tigers River and one sample from water drainage. The aim of this research is to assess the interaction of a fish lake on surface water by using isotopic techniques. The values of stable isotopes of 18O range-7.78 – 8.10‰, -7.43 – -8.11‰, -3.2 – 3.3‰ and -6.0 – 6.2‰. The values of Deuterium range -45 – 45.56‰, -46.7 – -45.72‰, -37.87 – 37.98‰ and -28.4 – -29.7‰ in the fish lake, Tigris river, groundwater and water drainage, respectively. The results show there is no effect of interaction between the fish lake and Tigers River due to a short distance between the river and the lakes, lack evaporation effects and high flow rate.
