A field investigation of the pollution existing in the Roanoke River
within the Roanoke Metropolitan district was carried out from June,
1940 to May, 1941 by various departments of the Virginia Polytechnic
Institute with the material aid of several other interested
groups. Studies of the chemical and bacteriological conditions, and
of the microscopic life existing in the stream were made by P. H.
McGauhey and H. F. Eich, of the Department of Civil Engineering.
The invertebrate and vertebrate life of the stream, as well as the
toxicity of viscose wastes to fishes, was investigated by H. W. Jackson
and Croswell Henderson, of the Department of Biology. Monthly
mineral analyses of water were made by F. H. Fish and others of
the Department of Chemistry, and data relative to certain industrial
wastes were furnished by R. A. Fisher and Dudley Thompson, of the
Department of Chemical Engineering.
