![]() Nitrification in a Shallow, Nitrogen-Contaminated Aquifer, Cape Cod, MassachusettsBy Daniel N. Miller, Richard L. Smith, and John Karl Bohlke ABSTRACTLittle is known about nitrification in ground-water environments
when compared to marine systems and surface soils. Ground-water
geochemistry near the upper boundary of a shallow, sewage-contaminated
ground-water plume on Cape Cod, Mass., indicated a transition zone
where O2 [24 micromolar (µM)] and NH4+
(37 µM) coexist. The occurrence and rate of
nitrification in this zone were investigated by a combination of
isotopic, biogeochemical, microbial, and molecular techniques. ![]() |
