Hallo Troy,
for urban hydrology we have analysed sewage waters from a large sewage
collector tube in Leipzig and sewage slug after treatment in an open basin
for N-15 of ammonium component (bulk) and deuterium (water component) .
Values are:
sewage water ADL 1 12.07.01 N-15 = +6,39 permil D= -59,5 permil
sewage water ADL 2 12.07.01 N-15 = +5,46 permil D= -59,7 permil
sewage slug KSL 12.07.01 N-15 = +2,35 permil D= -59,1 permil
Isotope variation depends on the origin of the sewage, on treatment, on
origin of water (here the waters represents the meteroric one), on various
components (NH4, NO3, R-NH-R', DIC, DOC etc).
I hope it helps.
