Penelitian ini dilakukan di Formasi Pamaluan, Pulaubalang, dan Balikpapan, dari Cekungan Kutai, yaitu kawasan konsesi pertambangan PT.Trubaindo Coal Mining, di Muara Lawa, Kabupaten Kutai Barat, Provinsi Kalimantan Timur. Tujuan penelitian ini, yaitu (1) mengkaji hidrogeologi dan pemodelan airtanah alami; (2) mengkaji, memodelkan, dan memprediksi perubahan pola aliran airtanah dan kuantitas airtanah dampak penambangan aktif dan penutupan tambang terbuka; (3) mengkaji dan memprediksi dampak aktivitas penambangan batubara tambang terbuka terhadap kualitas air (permukaan dan airtanah) dan memodelkan pola penyebaran kontaminan dalam airtanah

This research is conducted in several rock formations, which is particularly enclosed by Pamaluan, Pulaubalang and Balikpapan formation, from Kutai Basin, in the area of the mining concession PT.Trubaindo Coal Mining, Muara Lawa, West Kutai Regency, East Kalimantan Province. The objectives of this study are: (1) to assess the hydrogeology and groundwater modeling in natural conditions; (2) to model the impact of changes in groundwater flow patterns and quantity of groundwater on the open-pit coal mining and mine closure; and (3) to assess the impact of open-pit coal mining activities on water quality and to model the pattern of spread of contaminants in groundwater
