Relationship between chloride concentration and electrical conductivity in groundwater and its estimation from vertical electrical soundings (VESs) in Guasave, Sinaloa, Mexico

Abstract

(R> 0.94), to estimate the concentration of chloride ions as a function of the electrical conductivity of water in the study area. A geophysical survey was conducted through 34 Vertical Electrical Soundings (VESs) to calculate the water electrical conductivity from the interpretation of the apparent resistivity data. Twenty-nine VESs were used to relate the resistivity of the saturated formation (Ro) with that for the groundwater (Rw) by the linear equation Rw = 0.427 Ro + 1.987. Then, EC was estimated as the inverse of Rw. Finally, the chloride ion concentration was determined by the equation mentioned above. Following the same procedure for the five remaining VESs, which were acquired in places where there are no wells, the chloride ion concentration and the electrical resistivity of the saturated formation (Ro) and groundwater (Rw and its inverse EC) were obtained without requiring a destructive technique.

Representation of the spatial association between salinity and water chemical properties in Al-Hassa Oasis

“…Table 3 showed the resultant correlation between the extracted variables, revealing a relatively high relationship between water Clof the distributed samples and the respective EC with a correlation coefficient of 0.63. This comes on line with several studies that worked on examining the Cl --EC relationships and intended to estimate the concentration of chloride ions as a function of the electrical conductivity of water [26,27] . A study on concentration of Cl and EC for several salty waters in central part of Iran stated by Hajrasuliha [28] suggested an occurrence likelihood of a generalized empirical association among these two parameters.…”

Comparison of the efficiency of Deebag and jute made bag for faecal sludge management and wastewater treatment

“…Electrical conductivity (EC) is usually a representation of salinity and Cl- is a major constitute of saline waters that directly affect the EC values [ 22 , 23 ]. EC value was comparatively higher than the standard because from the Table 1 higher amount of chloride content was found in all samples.…”

Dietary Exposure of Contaminants through Drinking Water and Associated Health Risk Assessment

“…Sulphate (SO 4 2-) occurs naturally as a result of leaching from gypsum and other common minerals. SO 4 2-originates from sedimentary and igneous rocks [29]. The concentration of SO 4 2-in the district ranged between 9 mg/L and 1,432 mg/L in the samples obtained from sources and consumer ends of the district.…”
