| Summary: | The research area is located in the Tumpang Pitu mountain area and its surroundings, near the coastal region of Sumberagung Village, Banyuwangi District, East Java. The rapid population growth and the development of the mining industry in the research area have led to an increased demand for clean water, both for community needs and to support the operational activities of the mining industry. The purposes of this research are to understand the hydrogeochemical characteristics of groundwater, determine groundwater facies, analyze the processes affecting the chemical evolution of water, and analyze the distribution patterns of groundwater chemical parameters.
Measurements of physical water parameters in the field and chemical water analysis in the laboratory were conducted on fifteen samples collected from eleven drilling wells, two community wells, and two surface water sources. Based on plots on the Piper diagram, it can be determined that the research area falls into four groundwater facies: CaHCO3 facies, CaMgCl facies, NaCl facies, and CaCl facies.
The processes influencing the chemical evolution of water in the research area were identified using anion and cation plots against TDS values on the Gibbs diagram. From the plots on the Gibbs diagram, it can be concluded that the processes influencing the chemical evolution of water in the research area are the interaction between water and rock, as well as the dominance of evaporation processes. Based on the distribution of groundwater physical parameters, it can be seen that the distribution of physical water parameters is controlled by the direction of groundwater flow, which flows from the southern part of the research area to the southern part of the research area.
