“…The chemical quality of underground water varies depending on the type and composition of the perimeter of the plain (nutritional sources) and alluvium [11]. In order to evaluate the groundwater quality in Khezri plain, a well-selected well was selected in Khezri plain in the years 1385 and 1394.…”

The investigation of groundwater quality is one of the most important subjects in the field of groundwater resource. The main purpose of this research is the study of groundwater samples witch have been collected from 12 and 9 pumping wells throughout 1385-1394 years. The samples have been analyzed for major cations (Na, K, Mg and Ca), major anions (Cl, SO4, HCO3 andCO3) and physical parameters such as TDS, TH, Ec and pH. In following, the hydrogeochemical graphs such as Piper diagrams used for water classification. The analysis of results showed the increasing of TDS, TH and EC upper the limit. According to Schoeller and Wilcox diagrams, the water is not suitable for drinking purposes, agricultural and industrial uses. Such results are more helpful to manage the groundwater resource.

“…Water quality in an overexploited aquifer is worse than a well-maintained aquifer. A study developed by Bicalho et al (2011) concludes that greater volumes of water extraction and shorter times characterize intensive extraction in aquifers. The mobilization of the deepest water levels increases the mineralization of water while karstification is greater in an overexploited aquifer than in one that is not.…”

Background The importance of water to life is unquestionable. Most of the fresh water we use for daily activities comes from the aquifers, which in many cases due to misuse are overexploited and at risk. This article studies the aquifer that appeared in Laguna de Santiaguillo basin; it should be noted that the most important economic activity in the basin is agriculture. Methods By analyzing vector and demographic information, using GIS and with some field trips, the impact and risk on the level of disposition in every micro-basin that forms the basin were determined. Results The different modeling scenarios demonstrate that the basin and sub-basins that conform Santiaguillo are overexploited. Discussion The volumes concessioned are of such magnitude that they generate a condition of vulnerability to the activities of the basin and sustain the overexploitation conditions of the aquifer.

“…Therefore, further scientific studies on the heterogeneity and other physical properties of karst aquifers are required [19]. Previous studies on the effects of rainfall and temperature on water-rock interactions have been conducted [8,20,21]. Therefore, the analysis of climate data can provide critical parameters for understanding the hydrochemistry of karst regions.…”

Karst regions cover approximately 10% of the Korean Peninsula and are highly vulnerable to contamination. In this study, five field surveys were conducted between 2017 and 2019 to examine the monthly and seasonal changes in the hydro-environment of a characteristic karst region in Samchoek, South Korea. During the surveys, a total of 24 surface water samples were collected and analyzed for field water quality parameters, major and minor ions, and stable isotopes. The results indicate that the water quality in the study area is significantly affected by precipitation. Overall, the water was classified as a Ca-Mg-HCO3 type, and correlation analysis of the major ions detected in the water samples indicates that the inflow of nitrate to the surface water originated from agricultural activities in the region. Furthermore, variations caused by climate were verified using the relationships between the various ions. In addition, high precipitation rates during the rainy season cause the active exchange of surface material, which was verified using stable isotope outliers. The results provide a scientific basis for studying the connectivity of water systems in complex karst hydrogeological regions and can aid future sustainable management of water resources in these regions.
