A Study-Unit Survey (SUS) was conducted in summer of 2000 to assess the quality of water from drinking-water wells in the central Oahu groundwater flow system. The survey included 30 existing drinking-water wells randomly selected and spatially distributed throughout the flow system (see map below). Well characteristics, along with land-use and land-cover information were collected for each well.
