“…This study utilizes a novel combination of stable isotope analysis, vertical electrical sounding (VES), and audio magnetotelluric (AMT) surveys to provide independent yet mutually consistent lines of evidence for mapping the recharge provenance and subsurface ow regime of the Ababi Spring. The convergence of geochemistry and geophysics facilitates more reliable groundwater basin characterization (Aguedai et al, 2022), especially in complex volcanic terrains. To date, this speci c integrated approach has not been applied to delineate the Ababi Spring's recharge area, representing an essential knowledge advancement.…”

Identifying spring recharge areas is essential for water resource conservation. This study aimed to determine the recharge area of Ababi Spring, Indonesia, using stable isotope, vertical electrical sounding (VES), and audio magnetotelluric (AMT) methods. Rainwater and spring water were sampled at 211–978 m locations above sea level. Hydrogen and oxygen isotope ratios revealed that spring water originated from a higher elevation source. The relationship between oxygen isotope composition and elevation was used to estimate the spring recharge elevation as 2,118-2,137 m above sea level. VES and AMT methods generated geoelectrical profiles depicting subsurface water flow from recharge to discharge zones, confirming the elevated recharge area. Additional isotope analysis of 1,514 m altitude rainwater supported the prediction model. This multidisciplinary approach combines hydrochemical and geophysical techniques to enable more reliable delineation of groundwater recharge areas than single methods. Determining the Ababi Spring recharge zone facilitates targeted conservation efforts for this vital water resource. Further work should investigate geochemical evolution along subsurface flow paths.

“…In Morocco, Several studies have recently been conducted on the sources of pollution in many rivers, which indicate the deterioration of water quality due to various human activities [14][15][16][17][18][19][20][21][22][23] . CA, PCA, FA, and DA were used to assess temporal/spatial differences in surface water quality, identify potential sources of pollution, and assemble river monitoring stations.…”

In recent decades, water pollution has emerged as a significant concern, posing a threat to both humans and natural ecosystems. This study aimed to assess the spatial variations in water quality in the Nador Canal, Morocco using the water quality index combined with multivariate statistical techniques and geographic information systems (GIS). The parameters examined were then compared to the maximum permissible limit values recommended by Moroccan surface water standards and the World Health Organization. The results indicated that the WQI of Nador Canal is generally suitable for irrigation and unsuitable for drinking. It indicated that the quality of surface water in the Nador Canal is affected by organic pollutants, and this is evidenced by low levels of dissolved oxygen, the levels of elements were high, especially chlorine and sodium, in addition to a high concentration of ammonia, nitrate, and phosphate in some of the stations studied. Principal component analysis (PCA) results revealed that PC1–PC3 collectively accounted for 73% of the variation in surface water quality within the study area. The cluster analysis also proves that the water quality is relatively polluted. Potential contributing factors to surface water pollution include changes in the hydrological regime, household waste discharges, and agricultural activities. These findings furnish essential insights into water quality, particularly its suitability for irrigation, and contribute to enhancing the water quality management system of the Nador Canal in the Gharb region of Morocco.
