Tension-free lysimeters are installed in the Oa, Bh and Bs horizons at 3 sites located adjacent to watershed 6 at elevations of 750m (spruce-fir-white beech zone; SFB), 730m (high elevation hardwood zone; HH) and 600m (low elevation hardwood zone; LH). Three replicate lysimeters were installed beneath the Oa and Bh horizons and within the Bs horizon at the HH and LH sites, and two replicate lysimeters were installed in each horizon at the SFB site.

The lysimeters were constructed from either polyethylene funnels filled with acid-washed silica sand that drain into 1-L polyethylene containers or rectangular polyethylene containers filled with acid-washed Teflon beads that drain into 2-L polyethylene bottles. At each site, lysimeters were carefully installed in the wall of excavated soil pits, immediately below the Oa and Bh horizons and within the lower Bs horizon. Soil pits were backfilled to prevent accumulation of water and to eliminate freezing during winter months. Soil solution samples are collected approximately monthly in acid-washed polyethylene bottles and refrigerated at 4oC.

Between 1984 and 1986 and 1998-2005, data are the arithmetic means for samples collected from individual lysimeters. From 1986 through 1998, data are for bulked soil solutions collected from replicate lysimeters. Current detection limits for the Driscoll laboratory: Na (0.015 umol/L), K (0.12 umol/L), Ca (0.030 umol/L), Mg (0.0032 umol/L), Alt (0.0026 umol/L), Alm (1.3 umol/L), Alo (1.3 umol/L), NH4 (0.55 umol/L), H4SiO2 (3 umol/L), Cl (0.55 umol/L), NO3 (0.85 umol/L), SO4 (0.53 umol/L), F (0.097 umol/L), DIC (20 umol/L), DOC (20 umol/L), TN (0.81 umol/L). It is suggested to dataset users to use a value of one half the detection limit when a value for a solute is less than the detection limit. The data is physically located at the Dept. of Civil & Environmental Engineering, Syracuse University, Syracuse, NY and was last updated in February, 2002.
