Research Description
For nearly thirty five years, atmospheric acid deposition (acid rain) projects have been the bulk of the Downey research lab. The most important work has been in mitigating acidity in streams and lakes to protect and enhance fisheries and other aquatic life. An example of this type work is the stream liming in the St. Mary’s Wilderness in Augusta County, Virginia. Projects have also been done on the impacts of gypsy moth defoliation on stream water chemistry, the fate and analysis of herbicides and pesticides, aquatic water chemistry habitat information for amphibians and threatened and endangered species, fish otolith microchemistry, lake nutrient budgets and other environmentally oriented projects. Recently projects involving industrial hemp have been conducted.
