Abstract

Kapontori District, Buton Regency, Southeast Sulawesi Province" aims to assess water quality conditions surrounding the nickel mining site and identify potential environmental impacts. The study focuses on surface water located in the vicinity of mining operations, utilizing both physical and chemical parameters. The methodology involves water sampling and the subsequent comparison of laboratory test results against the standards set by the Regulation of the Minister of Environment and Forestry Number 05 of 2022. This research is expected to provide insights into actual water quality conditions, identify potential pollution resulting from mining activities, and illustrate the distribution patterns of impacts on surface water and community water sources. Furthermore, the study aims to offer recommendations for environmental management, specifically regarding pollution prevention, acid mine drainage control, and the improvement of mine water management systems. Scientifically, this research contributes to the advancement of knowledge in the fields of mining environment, environmental geochemistry, and mine hydrology. Practically, it provides a foundation for mining companies, local governments, and the community to enhance efforts in managing and protecting water quality in Kapontori District, Buton Regency, Southeast Sulawesi Province

Abstract

Labota Village in Morowali Regency holds significant potential for development in the areas of settlement, infrastructure, and natural resource exploration—specifically regarding groundwater and mineral deposits. To ensure the sustainable utilization of these resources, information regarding subsurface conditions is crucial. Combined geophysical survey results and field observations indicate that the uppermost layer in Labota Village consists of surface sediments or topsoil of relatively shallow thickness. Underlying this is a conglomerate rock layer with resistivity values ​​ranging from 2,000 Ωm to 20,000 Ωm. Quaternary sediments overlie ultramafic bedrock (Ku), which exhibits resistivity values ​​of ≥20,000 Ωm. The resistivity variations obtained from the survey are consistent with the lithological characteristics observed in the field, thereby reinforcing the interpretation of the subsurface layers
