This dataset contains primarily the EPA generated data for the EMMA (End-Member-Mixing Analysis) model that was presented in the associated J. of Hydrology (2015) publication. Part of the data for the EMMA and all the data for the water budget were not produced by EPA and were not included here. EPA did the analyses for SO4, Cl, and K and these results are in this dataset. An independent set of lab analysis was done by a non-EPA lab for K and this data is included as one quality control measure. The field collections of the samples for all of the data were collected jointly between several EPA field scientists along with the non-EPA cooperative agreement principal investigator and primary author of the J. of Hydrology (2015) publication. The site description data along with site locations are given in the dataset.

This dataset is associated with the following publication: Gracz, M., M. Moffett , D. Siegel, and P. Glaser. Analyzing peatland discharge to streams in an Alaskan Watershed: An integration of end-member mixing analysis and a water balance approach. JOURNAL OF HYDROLOGY.
