about all this testing, wondering if there s more testing that needs to be done. the ntsb says all the rail cars have been gone. there s only 11 that remain. these are a part of the ongoing investigation. still, though, residents frustrated and demanding more accountability. george solis, thank you so much. for more i want to bring in dan cannon who served as the liaison between the epa and the white house during the bp oil spill. officials are encouraging people to take the questionnaires. is this an adequate response? i m struck listen to your reporter talk about the complication with mish gand and other places accepting the waste itself. it s a reminder for me and for viewers as to how complicated these situations can get when you have contaminated water.
