Additional data on the removal of Chem Fish Regular rotenone formulation from water are presented. These data supplement the detailed report entitled Problems of Treating Water Containing a Rotenone Preparation Used in Fishery Management, issued February 4, 1957. There it was recommended that a rotenone preparation which did not use the hydrocarbon solvent (methylated naphthalene) would offer fewer problems at the water plant. Tests comparing the original and a reformulated preparations are reported here. The two preparations were checked for ease of odor removal by carbon and for persistence of odor on standing. The new preparation was preferable for Dickinson Reservoir application.
