Abstract
Development of industries and agriculture, salts, especially sulfates, used in many industries, such as fertilizers and pesticides, have become one of the most common problems. In this paper, a laboratory model was established to study the sulfate-contaminated transport process. Four samples of porous media contain the same pollutant, sandy soil, sandy gravel soil, agricultural (organic) soil, and calcareous soil. Where a pollutant is pumped at a concentration of 280 mg/l through a system consisting of a tube of length 4 meters and 8 cm thickness and distributed in the soil Each type is one meter. The results showed that all types of soils, except organic, had leaching or loss of sulfates from the soil and dissolving them with a soil solution. The transfer of pollutants from soil to the solution may reach between 50 to 300 mg/l per meter, while organic soil showed the ability to Absorption up to 100 mg/L per meter. However, it was found that organic soil contains the largest amount of sulfate and was able to adsorption, and it was found that bacterial activity has a role in reducing sulfate in organic soil and thus returning the soil to adsorption after a certain time of saturation process.

IntroductionThe disposal of pollutants or uncontrolled wastes is considered a dangerous source of soil, surface water, and groundwater pollution
Recent times, the problem of soil and groundwater pollution has become a major and common geo-environmental problem.Soil pollution occurring in a particular area can contain several different types of pollution or pollutants with a significant impact on the soil.The disposal of pollutants or uncontrolled wastes is considered a dangerous source of soil, surface water, and groundwater pollution
Organic sulfur compounds are largely immobile while inorganic compounds are more mobile and that sulfates)SO4-2( are more a sulfur compound has mobility, and the kinetics of sulfate is affected by the adsorption that takes place from the soil particles
Summary
The disposal of pollutants or uncontrolled wastes is considered a dangerous source of soil, surface water, and groundwater pollution Researchers in this field have conducted many experiments and studies where every polluted site has its characteristics, and pollution can be characterized by many forms and varies according to the nature of the site [1, 2]. Organic sulfur compounds are largely immobile while inorganic compounds are more mobile and that sulfates)SO4-2( are more a sulfur compound has mobility, and the kinetics of sulfate is affected by the adsorption that takes place from the soil particles. This naturally depends on the concentration of a solution in the soil, the type of soil, the pH, and other ions in the
