摘要：Conservation of the availability and guarantee of water quality from the spring is indispensable. One of the company as a provider of raw water in Surabaya made several efforts in maintaining the balance between quality and availability of water for sustainability . One method that can be used in aquifer monitoring of springs is the 2D Resistivity method. This study aims to describe the two-dimensional subsurface aquifers of Durensewu and Karangjati springs. The inversion result of 2D resistivity data shows the constituent rocks in the research area in the form of clay, sand, and loam clay with resistivity value 50-150 Ohm.m where sand rocks are identified as aquifer rocks at depths of 2-7 meters and a thickness of about 2-5 meters. The aquifers of Durensewu and Karangjati water sources are shown to have different systems. Escherichia coli contamination from domestic waste found in Durensewu springs is caused by aquifer connected to surface water flow, but not found in Karangjati spring.
