Abstract

The hydrogeological condition of a region is determined by the type of lithology, morphology, and subsurface conditions where the condition is very helpful in the study of groundwater exploration. Especially when we encounter interesting geological conditions when the groundwater exploration in the karst area in which volcanic rocks are resulting from the activities of the active volcano in the past. Groundwater exploration at Ponjong area and surrounding does have its special characteristics, because it has 2 different rock characteristics where the northern part of the research area in the form of a karst area (limestone of Wonosari Formation) while the southern part is an area of ancient volcanoes with dominant volcanic rocks from Wuni Formation, As for the research on the above and subsurface research area where the research is conducted based on surface geology mapping, geoelectric data collection, and groundwater sampling. Geological mapping includes geomorphological data, stratigraphy, and geological structure. The aquifer system of the research area can be divided into two systems, inter-grain aquifer systems, and fracture aquifer systems. Overall quality groundwater in the research area is quite good. Ponjong District there are mining activities that have resulted in changes in the land use system in the area. This can cause changes in the water surplus in the area due to the changing catchment area.

Abstract

PT. XYZ merupakan pertambangan batubara yang menggunakan metode tambang terbuka yang meninggalkan bekas lubang galian tambang atau void . Sisa lubang bekas galian tambang tersebut pada akhirnya akan menjadi tampungan air larian maupun air hujan . Tujuan dari penelitian ini untuk menganalisis dan mengkaji kualitas air didalam lubang bekas galian tambang (void) berdasarkan parameter fisika dan kimia air berdasarkan Keputusan Menteri Lingkungan Hidup Nomor 113 Tahun 2003 tentang Baku Mutu Air Limbah Bagi Usaha Dan Atau Kegiatan Pertambangan Batubara dan 115 Tahun 2003 Pedoman Penentuan Status Mutu Air. Pengujian kualitas air pada void di Desa mekar Jaya, Kecamatan Angsana, Kabupaten Tanah Bumbu, Provinsi Kalimantan Selatan dilakukan di UPT Laboratorium Uji Kualitas Lingkungan Hidup Provinsi Jawa Timur dengan menggunakan parameter suhu, pH, Besi (Fe), Mangan ( Mn), BOD5 (Biological Oxygen Demand), COD (Chemical Oxygen Demand), TSS (Total Suspended Solid). Penentuan status mutu air dengan menggunakan Metode Storet maka didapatkan hasil kelas( I) dengan hasil -28 termasuk pada kelas C, kelas (II) dengan hasil -14 berada pada kelas C , kelas (III) mendapatkan hasil -8 berada pada kelas B, dan kelas (IV) dengan hasil -2 berada pada kelas B. Masyarakat tidak bisa menngunakan air Kelas I dan II karena tidak memenuhi kriteria.
