Lake sensitivity to acid rain
Research in the Adirondacks suggests that watershed dynamics are the key to a lake's vulnerability to acidification. The Electric Power Research Institute's Integrated Lake-Watershed Acidification Study (ILWAS) produced a computer model that successfully integrated the physical and chemical factors that determine these dynamics. The research required an unprecedented level of awareness of how watersheds work and how rain, soil, forests, and rocks interact. One outcome of the field and laboratory studies was the finding that some soils act as buffers, taking certain ions out of the water, while some added ions. While the ability of the watershed as a whole to neutralize acid is the main determinant of a lake's vulnerability, seasonal changes demonstrate that time is a factor. The model is in demand to test water in other locations and to explore buffering agents. 2 figures.
