joining us now, dan simon was touching on it, elizabeth, how is the drinking water? >> it depends on so many different things. it depends on the level of these heavy metals in the water which we knew last week were very high. it depends whether, when they went downstream to where the water is taken in for drinking water, whether those water systems were given enough warning and we're told hey, shut off your pumps, don't take in this water, there's been a spill. but let's get to the levels of the metals in the water. they were very, very high last week. in fact, when the epa went out there, they were hundreds of times higher, in some cases thousands of times higher than the epa acceptable levels. now we're hearing that the levels have gone down. i think the toxicologists i've been speaking to say look, you want to be weary when we hear that the levels have gone down. it may mean that the metals aren't in the water so much, but that they settled into the sediment, the dirt on the bottom.
