Supporting information includes details on the design of the sampling network, including figures showing the elevations of each sampling port (Figures S1 and S2), sample collection procedures, analytical procedures, and a table of groundwater velocity estimates (Table S1). Sediment particle-size data and estimated cation exchange capacities are included in Table S2 and the results of sorption experiments documenting isotopic fraction of NH4+ are in Table S3. Figure S3 shows tritium data for a selected group of samples from the leachate plume.
Table S1. Range of groundwater velocities (m/year) calculated using minimum, median, and maximum hydraulic conductivities (k, m/s) and gradients (dh/dl).
Table S2. Sediment particle-size data and estimated cation exchange capacities (CEC).
Table S3. Results from NH4+ exchange experiments.
Figure S1. Location of MLS, IC, and SI well screens along the MLS 35-80 transect and water levels measured during sampling of the well transect (1997 through 2006). The MLS well clusters, which contained 7 separate wells screened at different depths are labeled −1 through −7.
Figure S2. Groundwater flow direction and slope of water table along the MLS 35-80 transect at different sampling times, corresponding to the same dates that the geochemical data were collected, May 1987, March through April 1999, June through August 2001, September 2003, and May 2006.
