The aquifer is described as limestone resting on impermeable floor of marine shale and volcanic sediment. Springwater was used locally during the Japanese Administration. Prior to 1946, water was flowing through a 4-inch pipe to a small treatment plant. In 1946, the spring had been abandoned, according to Glander (1946). Nicholson Spring is also known as Bobo Papago, Nickelson Spring, Papako Spring, and Nakada Zenko.
