Abstract

The study presents a study on the pollution of the water of the first aquifer in the seawater in the Kaam region. The study was based on the chemical method for determining pollution. The work was done on 15 wells in an agricultural area of 36 km² and the depth of the wells was from 7 to 70 m below the surface of the land where the water of these wells is used for agricultural purposes and human consumption. Groundwater samples were taken from these available wells and chemical analyses were carried out on these samples, including the concentration of hydrogen ion (pH), electrical conductivity (EC), total dissolved salts (TDS), anions, and cations (K, Na, Mg, Ca, HCO₃, Cl, SO₄.) Some of the related geological characteristics of the groundwater reservoir, such as the geological structure of the study area. The results revealed that the first reservoir in the study area was exposed to the invasion of seawater, which is probably due to the increased pumping operations in the past, which caused the penetration of seawater at the bottom of the reservoir, causing the low quality of groundwater in the region.
