A raceway in a fish hatchery was treated with hydrogen peroxide (H 2 O 2 ), as 1‐h flow‐through treatments, to simulate the New York State maximum allowable concentration (11.5 mg/L) in the receiving stream. Hydrogen peroxide concentrations were measured at various locations in the hatchery and in the receiving stream over a 96‐h period. At the discharge pipe opening in the receiving stream, maximum mean H 2 O 2 concentration was 9 mg/L at the end of the 1‐h treatments and 2 mg/L 1 h later; at a point 15 m downstream (midstream) from the discharge pipe, maximum mean H 2 O 2 concentrations were 2 mg/L at discharge and 1 mg/L or less (method detection limit) 1 h later. In a second set of experiments, a desired 100 mg H 2 O 2 /L was achieved in 1‐h flow‐through treatments only when the test tank was pretreated to initially establish an H 2 O 2 concentration of 100 mg/L before initiating the flow‐through treatment. When the 1‐h flow‐through treatment was administered without pretreatment of the test tank, a maximum H 2 O 2 concentration of 78 mg/L was achieved.
