| description | Determination of corrosion and scaling potential is one of the most important quality aspects of groundwater resources in different uses. Therefore, the aim of this research work was to determine the corrosion and scaling potential of Marvdasht Plain groundwater using Langelier saturation and Ryznar stability indices and their mapping through GIS. For this purpose, 49 agricultural wells were sampled for five years and total hardness (TH), total dissolved solids (TDS), total alkalinity (TA) and pH were measured. The ordinary kriging geostatistical method was applied for mapping the Langelier saturation and Ryznar stability indices and their components. The results showed that the spherical model was most fitted for these indices. The eefective domin varied from 15752 to 32711 m for the components and the spatial correlation class changed from good to fair. The mean Langelier index was 0.58 showing low to fair scaling potential. The mean Ryznar index was 6.2 indicating low corrosion potential of Marvdasht Plain Aquifer. Based on the zoning maps, the northern parts of the area showed the highest TH and TDS components followed by Langelier index, showing fair scaling potential. In this part, the effect of carbonate formations was evaluated as the probable contributor of the increasing the Langelier index. In general, the Marvdasht groundwater has fair quality in terms of corrosion and scaling potential. |
