Moreover, contamination metal levels were estimated. The Hossner and USEPA 3051 methods showed, respectively, average total contents of 17.2 and 18.1 mg kg−1 for Cd, 11.6 and 10.6 mg kg−1 for Co, 45.7 and 34.7 mg kg−1 for Cr, 1030 and 1100 mg kg−1 for Cu, 33,300 and 27,400 mg kg−1 for Fe, 963 and 872 mg kg−1 for Mn, 33.2 and 22.8 mg kg−1 for Ni, 791 and 782 mg kg−1for Pb, and 6320 and 2870 mg kg−1 for Zn. A lack of significant differences and a high correlation coefficient (>90%) for Cd, Pb and Cu between the two digestion methods suggest that the total-recoverable method (USEPA 3051) may be equivalent to the total-total digestion method (Hossner) for determining these metals in the studied soil. However, significantly higher concentrations of Cr, Fe, Ni and Zn were found by the Hossner method comapred with the USEPA 3051 method. The soil samples have very or extremely high levels of Zn, Cu, Cd and Pb contamination, indicating very high potential ecological risk.

The findings indicate profound document of changein climateshowed by the noticeable increase of the average mean annual temperature with the remarkable decrease of the yearly precipitation in the investigated meteorological locations. The impact of the climatic change on the hydrochemistry of Debaga unconfined aquifer was noticeable in increasing the water salinity as studied during the year 2014 and compared with the years before 2001. The Debaga unconfined aquifer water has indicated two groups’sulphate (79%) and chloride (21%) for the year 2014. It is clear that the climate change conditions increase the sulphate group in Debaga basin during 2014. It is recommended to overcome the water shortage by choosing an economical method of irrigation rather than the local traditional methods.

Influent concentrations for some important contaminants, which are TDS, oil and grease, TSS, COD, BOD, and turbidity were 2595 mg/L, 13934 mg/L, 466.45 mg/L, 2538.9 mg/L, 1739.2 mg/L, and 89.18 NTU, respectively, while the effluent concentrations were 1337.8 mg/L, 0.53mg/L, 21.7mg/L, 25.45 mg/L, 17.81 mg/L, and 7.08 NTU, respectively, giving removal efficiencies of 44.47%, 99.99%, 94.4%, 98.96%, 98.96% and 92.05%, respectively. All these results indicate that Al-Doura wastewater treatment plant was efficient in removing contaminants according to Iraqi and EPA specifications. Hence, the second part of this study concentrated on finding a simple and efficient treatment method to treat the effluent so that it can be reused in the boiler system. A pilot plant was designed and dedicated for this purpose, including three units of granular activated carbon f...

In this study, nine machine learning (ML) algorithms—namely, Artificial Neural Network (ANN), Decision Jungle (DJ), Averaged Perceptron (AP), Bayes Point Machine (BPM), Decision Forest (DF), Locally-Deep Support Vector Machine (LD-SVM), Boosted Decision Tree (BDT), Logistic Regression (LG), and Support Vector Machine (SVM)—were run on the Microsoft Azure cloud computing platform to model the groundwater potential. We investigated the relationship between 512 operating boreholes with a specified specific capacity and 14 groundwater-influencing occurrence factors. The unconfined aquifer in the Nineveh plain, Mosul Governorate, northern Iraq, was used as a case study. The groundwater-influencing factors used included elevation, slope, curvature, topographic wetness index, stream power index, soil, land use/land cover (LULC), geolog...

This area is totally covered by quaternary sediments. The sediments are composed mainly by cyclic alteration of clay, silt, sand and very fine gravels. Quaternary sediments represent the main aquifer for all parts of Baghdad governorate. Arc GIS 9.3 and GMS 6.5 programs were used in drawing high accurate estimating maps, to define salinity, type of the ground waters, the general direction of their movement, the distribution values of transmissivity of upper aquifer, with distribution and the amount of draw down for these wells, also drawing map for the ground waters depth zones. It can be concluded that the salinity of the ground water in Baghdad Governorate ranges between (fresh water – Brine water) in general, with the predominance of chloridic water type and the presence of sulphatic water type in other places. The direction of the ground water move...

A statistical multivariate analysis was done using cations and anions, pH, total dissolved solids (TDS), and electrical conductivity (EC) that were measured for drinking, livestock, and construction purposes. Residual sodium bicarbonate (RSBC), Magnesium Ratio (MR), and Permeability index (PI) were used to evaluate the suitability of the present samples for irrigation activity. The quality of groundwater in the study area is unsuitable for drinking water, industrial and building uses. But it is suitable for livestock uses, According to Residual Sodium Carbonate and Magnesium Ratio the groundwater in the study area are suitable for irrigation purposes, but unsuitable for Permeability index. Multivariate analysis results indicate the high positive correlation between Ec and TDS with other constituent...
