Deep-percolation rates estimated using a chlorine-36 bomb-pulse . Deep-percolation rates estimated using a chlorine-36 bomb-pulse method at three of the nine locations range from . to . mm/yr.

Deep-percolation rates estimated using a chlorine-36 bomb-pulse method at three of the nine locations range from . Because the mass-balance method may underestimate percolation rates and the bomb-pulse method probably overestimates percolation rates, estimates by the two methods probably bracket actual rates.

This report presents a study plan tor estimating recharge at the Hanford Site using environmental tracers. Tracers that have been used to study water movement in the vadose zone include total chloride, {sup 36}CI, {sup 3}H, and {sup 2}H/{sup 18}O. Atmospheric levels of {sup 36}CI and {sup 3}H increased during nuclear bomb testing inmore the Pacific, and the resulting "bomb pulse" or peak concentration can be measured in the soil profile. Seven study sites on the Hanford Site have been selected, in two primary soil types that are believed to represent the extremes in recharge, the Quincy sand and the Warden silt loam.

High soil water NO 3 concentrations (up to 136 mmol L1) were found only at the watershed ridge top during the 1996 . The Arbutus Lake watershed has been the site of several recent N studies focused on the importance of dissolved organic nitrogen in watershed N flux.

High soil water NO 3 concentrations (up to 136 mmol L1) were found only at the watershed ridge top during the 1996 snowmelt and early summer. The Arbutus Lake watershed has been the site of several recent N studies focused on the importance of dissolved organic nitrogen in watershed N flux, the impact of near-stream wetlands on stream water N and DOC chemistry, the effect of landscape position on N mineralization and nitrification [Ohrui.
