This study aims to enhance understanding of the hydrogeochemical behavior aquifer by utilizing a water quality index in conjunction with analysis. The focus is on identifying factors that control its chemical composition and influence suitability for domestic use. Water samples were collected from twenty boreholes analyzed major ions, pH, electrical conductivity during dry wet seasons. During season, indicated generally good quality, an average score 96.12. was categorized as Excellent (5%), Good (55%), Poor (40%). In contrast, season showed slight deterioration 102.57, reflecting distribution (10%), (35%), (55%). Boreholes located western central parts exhibited better compared those eastern part, which are considered unsuitable human consumption due their poor quality. mineralization process primarily attributed dissolution dolomitic evaporitic formations, resulting various facies. dominant facies identified calcium magnesium bicarbonate (85%), followed sodium (7.5%), sulfate chloride (2.5%). underscores critical need sustainable management practices protect groundwater Mitidja plain amid ongoing environmental challenges. Addressing these issues essential ensuring safe drinking availability local communities.

Abstract The southern sub-district of Pujut, which encompasses Mandalika’s Special Economic Zone, is a region focused on industrial and tourism growth. Groundwater supplies are necessary to fulfill the demands local population sector. In groundwater exploration, one important parameters hydrochemistry, whereas, in research area, more studies needed this topic, especially relation hydrogeological conditions. objective comprehend hydrochemical properties system present region. A total 9 samples from drilled wells 2 springs were collected assessed ascertain concentration primary ions. diagrams developed by Piper Stiff employed categorize facies establish their correlation with geological results revealed that chemical composition was classified into four unique categories, demonstrating differences systems. Group 1 comprises Ca-Mg-HCO 3 characterized bicarbonate water associated calcarenite limestone volcanic breccia. Ca-Cl facies, distinguished presence rich chloride. These occurrence saline or brackish frequently observed close proximity shoreline. mixture Na-Cl-SO 4 characterizes group 3. sulfate ions high group, existence due oxidation sulfide minerals altered breccias. mix Ca-Na-HCO type alluvium deposits. Based previous explanation, has potential be exploited facies. According can utilized

Analysis of the Spatial Distribution of Seawater Intrusion Using a Hydrogeochemical Approach: A Study of the Coastal Geology of Kebumen Regency, Indonesia

Geosfera Indonesia, Journal Year: 2024, Volume and Issue: 9(2), P. 228 - 228

Published: Aug. 31, 2024

This study examines seawater intrusion in the southern part of Kebumen District, focusing on impact various geological formations groundwater salinity. Groundwater samples were systematically collected from 11 locations representing alluvial, volcanic, coastal sediment, and karst conditions. The analyzed for major ions, including calcium (Ca²⁺), magnesium (Mg²⁺), chloride (Cl-), bicarbonate (HCO₃-), as well Total Dissolved Solids (TDS). Ion ratios such Mg²⁺/Ca²⁺, Cl⁻/HCO₃⁻, Mg²⁺/(Mg²⁺+Ca²⁺), along with Fraction Seawater (fsea), calculated to assess extent intrusion. employed Gibbs diagram method identify primary processes controlling chemistry, revealing that water-rock interactions are dominant most samples, particularly those affected by results indicate significant alluvial regions, especially at sampling points TP 2, 4, 10, while volcanic sediment areas show minimal These findings underscore critical influence conditions highlight need targeted management strategies. Further research long-term monitoring is recommended better understand mitigate impacts this region.
