✦ Synopsis

Many lakes in the northern Great Lakes region may be sensitive to acidification because of watersheds with low buffering capacity (e.g., shallow soils over bedrock or deep, coarse, outwash sands).

The objective of this study is to evaluate effects of simulated acid rain on the chemistry of leachate from a moderately low (18%) base-saterated sand typical of large areas of forest soils in the Superior Uplands. This province includes the Boundary Waters Canoe Areas, Rainbow Lakes, Sylvania, and many other Wilderness and Natural areas.

Intact soil cores were collected in 15 x 30 cm plexiglass sleeves; the base of each was fitted with a 70 micron porous plyethylene filter and tubing to collect all leachate passing below the root zone. A white
