Measurements of nitrogen concentrations from grab samples collected from McRae Ck, and from a network of shallow wells located adjacent to the stream. All samples were analyzed for NO3 and NH4. Some samples include additional data such as DON and Total N, and sometimes temperature and dissolved oxygen concentrations were measured at the time the water samples were collected for analysis. Data were collected from September 1989 to September 1992 on an irregular basis to sample both baseflow periods and storm events across seasons of the year. Water samples were collected from the stream as grab samples; samples from shallow wells were pumped into a small flask using a vacuum pump and then transferred into a sample bottle.
