Aquifer characterization through the construction of groundwater production Well in Suwawal Village, Pakis Aji Sub District, Jepara

Kampung teknologi Jepara located in Suwawal Village, Pakis Aji Sub District, Jepara Regency, Central Java with an area of ±140 Ha. Integrated analysis from groundwater surveys resulting two (2) potential location, which is SWL-10 (potential 1) and SWL-21 (potential 2). Potential aquifers of SWL-10 located in a depth of 13 to 82 meters and >114 meters. Potential aquifers of SWL-21 located in a depth of 12 to 60 meters and >87 meters. Groundwater drilling conducted in SWL-10 shows that this area composed with lithologies such as: soil from weathered rocks (0 to 10 m depth), breccia (10 - 38 m depth), tuff with medium to coarse sandstone intercalation (38 to 68 m depth), sandy breccia (68 to 90 m depth), and tuff with medium to coarse sandstone intercalation (90 to 125 m depth). Water debit in this well as much as 5.8 1/s. Potential aquifers lithologies in this area are sandy breccia, breccia, and sandstone. (author)
