Permeability, effects of age, and water table fluctuations were
studied for nine drainfields in five soil types ranging from well to
poorly drained. Three sites were in Willamette, one in Woodburn,
two in Amity, two in Concord, and one in Dayton soils. Before
permeability of drainfields could be evaluated, methods...

The reaction of several primary amines with nitrite was investigated
with regard to the formation of N-nitrosamines. When reacted
in a low moisture system at 160°C with a 1:2 molar ratio of amine to
sodium nitrite, various primary amine hydrochloride salts were found
to give rise to heterocyclic nitrosamines. The...
A laboratory study of anaerobically digested sewage
sludge was performed to measure equilibrium constants for
ammonia in the sludge. Measured constants describing the
solution and dissociation of ammonia in sludge were compared
to theoretical constants obtained from thermodynamic data.
No significant difference was found between these two sets
of constants....
