Total Effluent from Onsite Sewage Disposal Systems (OSDS) - Hawaii

This layer represents the total effluent coming from onsite sewage disposal systems (OSDS) (e.g., cesspools and septic tanks). OSDS point data were obtained from the University of Hawaii at Manoa (UH) (Aly El-Kadi) and the State of Hawaii Department of Health (DOH) (Bob Whittier) that estimates effluent flux from each property, or Tax Map Key (TMK) parcel, with OSDS. The Ocean Tipping Points (OTP) project converted the points to raster by summing nutrient flux values within 500-m pixels. A Focal Statistics tool was then used to calculate the total flux within a 1.5-km radius of each offshore pixel. Units are in gallons per day per km squared. The area of interest is from the shoreline of the Main Hawaiian Islands extending 5 km offshore and 1 km inshore.
