but that meant it would not source from lake huron and instead would source from the flint river. at the time officials celebrated the switch. soon after there were problems with discolored water and eventually news of lead. a year and a half later flint switched back to detroit water. >> well, the kindest thing you could possibly say is they were completely incompetent, sloppy, lazy and uncaring. >> specializes in water treatment. his team has independently tested water samples at hundreds of homes throughout the city. >> when we first got the results we just didn't believe it. it was hazardous waste levels of led coming out of this person's tap. two and a half times hazardous waste levels of lead in the water. >> turns out, it was so corrosive even after going through water treatment control plant, that it started to eat into the lead pipes, causing the lead to leech into the water. >> what makes it so corrosive? >> it's high chloride in it. it's perfectly fine for fish, and to canoe in. but the salt level in the water will eat into pipes. that's what happened in flint. >> even

we needed to go back because we know that lake huron water was treated.e corrosion going on that the flint river water had. but when we made that switch, our pipes were damaged by that corrosive water that was coming from the flynnt river. so that's what happened. the biofilm was torn down. we don't have that anymore. that's what was proeblt protecting us. so when the water comes through the lead leaps out. that's why there is still a problem with lead. so we made the switch back to detroit. one of the things you talked about is the permanent damage under the age of 6. we know they have newer lonl cam damage. they are going to have to provide services for those kids and families because we know they're going to show some deficits. >> the mayor was elected by the people of flint, michigan, in large part to fix this problem. we came in knowing this is what they needed to do. this is a herculean task ahead of you, ma'am. good luck. keep us apprised. >> i thank you for that. thank you so much for having me. >> thank you, mayor karen weaver of flint, michigan.

look at the lake effect snow coming off of lake ontario, lake erie, superior, huron, even michigan there. and this is the perfect setup for lake effect snow when you have the cold air getting dragged out of canada courtesy of stronger winds out of the northwest or west, over the warmer lake waters, you get the condensation to form as that interaction's going on and then you get snow forming and the wind help blow it downstream and all the way to new hampshire, pretty crazy. for concord, we haven't had measurable snow and we tied the date for the first snow today. if we don't get any snow today we'll continue to climb up the list. the latest we've had the first snow in concord was on january 13th, the year 2000. so we have a ways to go, but i'll tell you, today is really the only chance within the next seven days of seeing any measurable snow in concord, or at least a trace. so we'll have to do it today or it's going to extended past christmas. >> 31 degrees in concord and manchester. temperatures not all that chilly this morning, it could be a lot worse for this time in december, right?
