3. The rate of disappearance of coliforms differs at the 
three outfalls studied, being fastest at Orange County and slowest 
at Whites Point. The differences in these rates seem to be associ- 
ated with the settling characteristics of the particulate fractions 
of these effluents. 
lh. It appears unwise to base any predictions of the behavior 
of the proposed outfall on the disappearance rates measured for 
the three effluents and it is proposed that similar measurements 
be made during discharge of primary effluent from Hyperion.
