CFACT is concerned that EPA is mixing good, properly conducted scientific studies (that show minimal atrazine risk to aquatic plant species) with poorly conducted, largely meaningless studies that combine inadequate data, satellite imagery, statewide crop and atrazine use data, computer models, laboratory evaluations, algorithms, extrapolations and best guesses, along with irrelevant toxicity studies of non-aquatic plant species that were tested for high-level exposure to atrazine-based products.
