anne great to see you as we shed light on this, we are talking about 400 tons in the bay alearn including all times of raw sewage even a sofa from one image i saw. >> they have two basic problems. they have all that debris if you will sofa plastic bottles, shoes i saw. but they also have a problem that raw sewage goes in to the water where's the olympic athletes will be competing. only about half of the raw sewage is actually treated in rio. and when stharpthey were granted the games they promised they would get that number up to 80%. it's not going to get there. city officials have admitted that. >> what is astounding now is you have american athletes already in the waters already training here in the waters that's questionable. here's what luke mcgee coach of the u.s. national men's rowing team, had to say about the water danger there. >> it's certainly a concern for us and something that we have been in constant contact with the ioc and our federation and
