Data were collected to verify the suitability of the new 4-Nitro-3-(trifluoromethyl)phenol (TFM) bar formulation for wide-scale use in the SLCP. The following objectives were used to achieve this goal: (1) complete randomized experimental applications of new and old TFM bar formulations in three low-discharge tributaries on consecutive days, (2) experimental applications of new and old TFM bar formulations (including bars previously stored at elevated temperatures) in a laboratory constructed flume, (3) compare and contrast the release profiles of TFM from bars of the new and old formulation as determined from the measured concentrations of TFM in water samples collected every 30 minutes for 24 hours, and (4) evaluate if the duration of TFM release from the new formulation during field applications is sufficiently improved to be acceptable for routine use by the SLCP. Other evaluations included analysis of the % Active ingredient in both the new and old formulations, and hardness determination of the bars at both room and elevated temperatures.
