detritivores are favored directly by organic loading associated with the sewage 
input, and indirectly by the products of inorganic nutrient loading (3, plus 
additional project data). 
The relative impact of streams, rainfall, and sewage on freshwater and 
nutrient delivery on Kaneohe Bay can be established by a simple budgetary 
analysis. Sewage contributes a minimal amount of freshwater (Table 23-1); 
however, sewage accounts for most of the nitrogen and phosphorus delivery 
(Table 23-2). 
The bay may thus be seen to be sporadically perturbed by fresh water and 
associated sediment delivery, and chronically perturbed by nutrient delivery. 
This latter perturbation, which has increased dramatically over the past two 
decades, will be terminated.
