Evaluation of some Physical and Chemical Properties of Ground Water in Alshirqat District, Salaheddin province, Iraq

Abstract

The study carried out to evaluate some of the physical and chemical properties of the ground water samples from west of Alshirqat district, Salaheddin province, IRAQ. Six wells selected, sample of water collected every month for 6 months (October,2021 – March 2022). In each sample electric conductivity (EC), pH, total dissolved solid (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), total hardness (TH), calcium hardness (Ca H), magnesium hardness (Mg H), sodium (Na), potassium (K), chloride (Cl), and sulphate (SO4), were measured monthly. The results of ground water samples range of EC is (1308-6030) µ siemens, pH is (6.99- 7.95),TDS is (947-2670 mg./l), DO is (4- 6.7mg/l), BOD is (0.4-2.6 mg/l), TH is (500- 3200 mg/l ), CaH is (300- 2000 mg/l) , Mg H is (20 -1800 mg/l), Na is (50- 2100 mg/l), K is (0.1- 7.2 mg/l), CL is (133.12- 2485mg/l), SO4 is (12.71-375.6 mg/l ) subsequently. The ground water in west of Alshirqat, Salaheddin, Iraq, contain very high level of total dissolved solid, total hardness, calcium hardness, magnesium hardness, sodium, chloride, and sulphate. The ground water is unsuitable to human consumption and domestic uses, for animal uses, irrigation except plant resistant to salinity, and many industries.
