zoning of the southern coastal region of the iran based on pollution of water resources (case study: minoo island)

The purpose of this study is to assessment and zoning of water resources pollution in the water resources of minoo island in the south of the iran. the type of research is applied and the method of laboratory is done through field harvesting. for this purpose, the study area was networked and the networks that had an aquatic ecosystem were selected as the study area. sampling of water (surface and underground) in the area was performed and transferred to a trusted laboratory. the results showed that there are 3 types of water resources in the study area; arvand river, surface rivers and groundwater. the average of tds was between 1100-1600 parts per million (ppm). the arvand river is more polluted than other sources. the highest levels of as, fe, mn, cr and al are 0.425, 0.585, 0.883, 0.102 and 2.22 mg / l, respectively. the ph is normal and will not be a problem for sensitive plants. also, groundwater resources located in the northern half of the study area show the highest level of pollution.
