جودة مياه الري (المياه الجوفية)‎ في بعض مزارع مشروع حمزة الزراعي

الملخص EN

This study aimed to determine the quality of irrigation water (groundwater) in farms located in the Hamza Agricultural Project, by studying some physical properties such as color, taste, and odor in addition to measuring pH and electrical conductivity (EC), as well as studying chemical properties by measuring Some metallic and heavy elements such as (iron, copper, nickel, lead, cadmium).

samples were collected from (8) wells at a rate of (5) liters / well, and at a rate of (3) replicates / well.

the results of the physical properties showed that all wells have no taste, odor, or color, while the results of (pH) ranged between (6.5-8) and are within the permissible limit, except in the second well (4.8) less than the permissible limit, while the conductivity results were less of the permissible limits in the third, fourth, fifth, sixth, seventh and eighth cultures (189.6, 182.3, 224, 183.3, 223, 430 µS / cm) respectively.

while the results of the detection of metallic and heavy elements showed that iron was less than the normal limit and ranged between (0.02-0.01 ppm), except for the sixth well below the detection limit, and copper is less than the normal limit in all wells (0.11, 0.04, 0.04, 0.02, 0.03, 0.02, 0.02, 0.07 ppm), while nickel recorded higher than the permissible limit, which ranged between (0.8-0.05 ppm) except for the first and sixth well below the detection limit, while lead recorded at high rates in all wells where the concentrations were (0.15, 0.17, 0.11, 0.06, 0.11, 0.13, 0.33, 0.09 ppm), while the cadmium concentrations ranged between (0.01-0.001 ppm) except for the second well without the detection limit.
