ABSTRACT

The primary objective of this study is to evaluate the quality of water resources, and its suitability for various purposes, in Al-Teeb town, northeast Maissan Governorate, south Iraq. Groundwater and seasonal Al-Teeb River are the main resources of water in the study area, which is characterized by arid to semiarid climate. The hydrochemical study involved the analysis of major cations and anions, trace elements and physical properties the total dissolved solids (TDS) and pH, for 16 groundwater samples and 4 river water samples of the period 2014-2015.

Groundwater samples were collected from 14 well represent the quaternary aquifer, as well as 2 well samples represent the Tertiary confined aquifer. The water of both the river and groundwater of the quaternary aquifer in the study area is classified according to the TDS as moderately brackish water. Whereas, groundwater of the Tertiary aquifer is less salinity and some wells are classified as fresh water. Moreover, the type of water is (NaSulphate) for most samples.

Chemical analysis of trace elements show an increase in the concentration of lead, nickel and cadmium more than their standards limit in all samples according to the World Health Organization, and the Iraqi Standard, whereas iron and manganese are more than their standards limit in some samples. Piper diagram classification shows that the water type classification for all samples is: Earth alkaline with an increase portion of alkalis (Na2++K+) and prevailing sulfate and chloride ions, this result are the same for both surface and groundwater samples for the two seasons. Such water is mostly unsuitable for human and building uses, but it suitable for livestock and permissible for irrigation, except two samples from the Tertiary aquifer that are almost suitable for all purposes except human consumption.
