Today we're I'm here for a recap lecture series of the series sponsored by the York kept me going to environmental engineer named family kept looking for executive director of the. No need for him but he actually got the if you're not the leader with the specialist for patients of environmental scientists who meet the demanding criteria organization. Very rarely right one distinguished environmental engineer of the academy. If you mean that can't be left sure each year and this person takes it like a really campuses around the way and will probably be one of those my dear Dr Carson is this your work your brother. Welcome to you once upon a time the sun approaches the youth and Guard during the movie I'm sure that is derived from offer visions put into abortions the scene the feel good. Affirmation that they are good enough to be done. He approaches a whole group not very much on chemistry. Dr Patterson is a member of Generation professional earthwork who portrayed the principle chemical engineering chemistry into the pros are all very fun to see what Dr Drew you write the text concentrator Google no way three. You could go to war when you needed some information technology dating from the nineteen seventies. It's still enough to fill two of you to go through the usual information will tell you all. Right at the school our parents are a professor sure normal engineering had no way to technology here so since then he's continued to work as a practitioner and each person barring the fall for something like that is a conduit for working with just three manufacturing industries and service industries all run over all the office least a couple of books and main papers in the field and the driver not to look worldwide wrong number of occasions to do it here in the state of Illinois whether they did the early back to a master's degree from Harvard University in the US older although the loss of your living room or go go. Ph D. be worth your four hours are Colorado where he spends an undisclosed amount of time victims where the focus of this lecture giving the focus on work that he's done some of the work he's done over the years family. So it's mediation terminated so much. Technical options and environmental consequences like just a really poor reader feeling the leisure one feel for most all my career. We share a room where your daughter will hope for a number of your friends. So it will be to see you again. Welcome here for over a year or so when we're thinking we will have a reception or honor of the third or a groom after his life. Thank you John thank you very much trying to live to be here Ira. Good Your parents never really time over the years but I haven't been here for twenty years like to say to him every day for men to come out some of the faces of change by getting gray beard the bank will be more vivid than that. So I'm going to tell you about a real life crime scene not a crime you know I mean he's a good example to demonstrate some of the conflicts I want to discuss computer day. I'm going to blinded to hear questions become answers. Just in to get out of the road. I want to hear that you know. OK We're going to talk about the video you shot ten days seven reducing your own rather complex issue and what a lovely brain you have a very cautious. If you know what you're doing before you do it. The problem is sometimes more harm than good. There are pros and cons for why we do so would be a good. The first one should be in the just part of the reason we do it through good rights labor the ability to do so long for a member of their own overlying waterpolo because he's aloof or probably not back up into the work going to effect the line the war on here resisting ended by our your own just to bore you with the pitch right off the bat and leader of I will use a lot thirty five percent of us like say ridge on the great life and twenty four percent of us remember how wrong constructive I prefer you to settle with associated below the blue dye to be and I hope the other not like a bum and we pride ourselves in the United States over him and have a long and successful career a pollution protection here was funded in ninety seven the off every ninety seven life thing. Yeah. And we've done it for months now and here we have left the rest of more or less. History. My radio talk to contaminants in our environment that are still there. David Kay. The reason we hang out is because not because we don't have the will to play tomorrow. But the cost. The process of playing it for many years I have never been a prenup spend more time because we're very cautious very very sport. We have to draw on the very best environmental science and engineering that we have available on the foreground of how we're going to deal with the impacts remediation of what the site. If you mess around with a good set of headphones you Randi. Never pick from the media the serving of the government who are all they can be quite clear Godi Carsley and of course their long term effects and this of my word you really know for less about the consequences of alternative remediation options F.A.Q. remember the patients that we need to know we have a long way to go learning her and if people like yourself over you doing research and think about it. We're going to help for all this is how the current religious stuff and these are general they're going I think typically high salt mines all high or anything including you need to get involved Grable or are demanding. So this is how often good to see you know that you know I would never go to zero zero under our roof or something that doesn't happen. They are very rare but if you go out thirty seven P.M. You know often a man would drive the dissolved off the river. They're written in or anything including talking no to better reduced day and morning room for folks to get far likes to have a long nap or want to risk the time there. Ali British and fertilise very prolific I did find disturbing the settlements and a lot of those trophy cabinet. I pray my face kind of thing the religion to work on you can actually drive the war by the more you probably the more you try THIS IS A B. C. the what's out there are many here you know obviously the whole kind of war game. You know to say it's a must for me you go studies have all night and night there was going to have you know any sort of talk you know you know you know I don't tell family I will hold off for Game seven including P.C.T. about their acceptance of the United States have to be you know have a good pal No I'm sorry but that means they're the flux of the residual settling down of our impacting the Bali the Warco and the one form of the overlying war. So there's a way out and fortunately we really find a set of them that only get one or two of these many of the seven. They are doesn't want to go out of the house. We're dealing with the past the rise of contaminants of different physical chemical characteristics and a different type of group we have a we haven't had a really really. Yes. Take on all of you know we're a good war but we this is what we're working with right now there's something called Market national recovery of him in our what it means to stand on the shore you want to take twenty five years you might have twenty five things to do what it does sound like a very proactive way to get at it but where there are media such as you'll see a moment where the E.P.A. and the State of the engineering team. On the side to save the world or the sun it's better to leave it alone if you go there and disrupt this crap and now I'm just camping OK having means we could literally. Go down to the settlement interface the water and we put some sort of a camp there between the set of the contenders and the water on the ideas of that can't walk hinder or slow the flux of contaminants from the sediment back up in the water call him to come back here a little bit for the one that will be more familiar to many of you would be gravely. Are we going to react to pull out the settlement or take the long national butt out for a ground invasion to go over the landfill something they're going to wait to do what is the old favorite cannibal bridge where you drop a big pleasure walking down loaded up the stuff and the others or curtain more and I probably agree with heads up over Benghazi just a bit and then there are a few of her big technologies but we're wide open to you on the suggestion I think that they fall into this institute fixation stabilization of Syquest crazy and that's where we put something down into the setting of the reactor they're going to town because during certain times I'm up chemically usually so they will flock up and really work on the foot of the cross section the canopy further but we put out a camp there a couple plaintive really we need to be favored I wanted to get response to the site. You know sort of the focus on board for the state but we are of the stuff we put down to something. You see sand and gravel to sit on top of the sediment and it's intended. Well they're all contained. There's a lot of sort of the stuff I live in a certain sort. But we need to make sure that we. Viol doing now. Thank you for having him redevelopment because he put down something on top of the film. If you basically wiped out the events of the build those are a very important part of your Why do you feel this is what I can't look like a cross-section. You got to contend a set of those no they put their foot forward play so they feel they are physically just bowled over gravel of there is now something on the market called Act of War which is the fire of players as you put down the seven and then they do that to put it down the slope of the ball for pleasure for the vintage the previous definition to get cross-section either said something like a set up here I'm not sure I want my lifeline to go back and forth like that with what they do with just going through the hole. With one down again we have to make sure that the kids are going to be stable. We don't know tell or turbulence our brain right all ready they are there to walk to camp and one guy would be down there is going to speak. Maybe a stable job won't get washed away by natural Riverview focal reading is not to be saying they will and I will be blowing Dushan but reactive if you are thinking out in terms of their materials exist don't discuss it with really just for example like a put down of six foot we are going to put up with water column but they're pretty well of eliminating you so that workers. When they go in this kind of thing summer camp. Should not be of such a nature that it interferes with the appropriate uses of the roof over our going back out there are a we said that a lot of that recover it. It minimally destructive going to do anything going on here coming from an adverse effect but what it does to interpret sent to a multimedia year radiation escaped all over the many people in this room a lot. So it is not helpful. Politically or socially the community the city or the bank for that impacted river or harbor like they started you coming in as I mentioned there are signs saying well here's our plan about always going to pay for three years. You don't get a very warm reception. But again you're saying reduce their standing go out to do a solo. We can't grow up quickly make a reduction so what my code under other circumstances the bridge for the five or six previously that might be a true friend or two. OK big city here. One of the problems with when you politically active understanding grapple if they freeze Greece's bail. That's certainly been released a list for poor water this highly contaminated soul searching for water shooting up into the water coming as low blow out. So there is a very quick and a media frenzy effect on the water for a fee and be a factor. We're going to talk to you know we're going up on the white gritty of those fairytale you know you did the local community life which is to get the police out of the water column out of the river the way up somewhere off base. Somebody's backyard but hopefully it doesn't probably be put into something like ten point plan with something that's sort of over the long term impact of it or not quite. The problem with that is as we really became a real fan and her problem and who is into all the contaminated sentiments were exposed because we did it down through a layer of sort of the revealing you think that everyone pay off all the way to the bottom of the letters so we're pulling off and leaving a layer of pretty talk in the period leading up to come back a second or third past the course that destroys the good of the community and in addition if you will see their way for an up and sort of management issues that are quite difficult to deal with and very human. I just to give you some idea of what this is a writer's care a lot of remedies are involved. This is something like And for me. Anybody on the supervised side of the DID address for several years you know just under seven long marker that we've got around what you know about four percent of all the happening but that percentage is going up. Now the pre-game work period with how it can happen and what the pros and cons of the campaign are pretty good but farther down the one that the one that's a very politically powerful time we're going to get to know their backyard and then fixation another pork in that is also easy to write and we see that all right. Because at the same speed. No one perfect solution and each of the solutions will probably come from the stuff I want to quote from a National Research Council report and the first couple of off course there are things I just said detectives include for media to prove the set of an article I really having are covering the main material drawing on networks when you weigh. Us this. That's what we've just been talking about. That's our catalog talking. So I can think they're going to say so I commissioned report to her would be a tell me anyhow today they're off our program and that very much through this rare off the top five. Single remediation take me to a contaminated. One by a river Arbor like somebody you know generally your theory but the bottom line at least a couple took a different course is both appropriate for the level look at Paramount where the contempt for local you know their right over the whole of the combines to overflow or how they are delivered have a good share of the sky the last time it is one that I can tell you is probably the most important for us. The scientists the city to develop where the bridge you compare needs that of life to prove to be among the most controversial is to my next life where all fifty million dollars or more plane up there is huge debate in Congress. What's right what's wrong. How are we going to get at it. What are we going to do I thought here a little bit more than I did for the Clinton camp about some of the issues that really drive that debate discussion or debate getting more the better if waterboarding impact because the risk associated with dredging and all the others is how bad are we going to go over one or zero people now on the second run through the mall on the list by mistake again. Packed with detainees daughter home or their families as we talk about our demand for the media not to demand a long time off a man or a body. That could be quite significant or talk him out on the board partially release a look or preview. She was crying foul. Cumulative and something that we should not have it is a fine until you hear their potential legal consequences to this not just an economic to legal issues like for example in the process of implementing a totally approved media crime. We might result in following one standard and we are by far the robot you live with that you know protected your car if you do something to prove the right to receive the work one criteria you know I'm going to enjoy them whatever they do is baffling degradation of water use and use a right to somebody downstream relying on their water for cooling tower or some other application. We still get from their water flow. They can use that water for their right to rely on her as a period you'd better run over to do what you like that was of the our demand in Canada by going to run through the power to run the program that he didn't know they were doing then or against the result of the media talk to them and why don't you go copper in this conflict of interest what it is going to mean in the long run the good argument for here by night is not the most risky part of the money not. Don't get me wrong I mean here's a case study just up river call or whatever. You know that was calculated start out I'd like to know what of a go both North East Green Bay now and let me just sort of out for tomorrow. All wrong. All I want to go off and revise and I'm going to demonstrate some of the concepts pretty obvious cussing talk about remediation of the war are really difficult. So are there we're back to over the contempt. We all see because of her including the see the mercury in pesticides they see the relief from something called Harvest copy paper production ran for the recycling operation on the river triggered nineteen fifty four percent about ninety seventy one. You know over the flux of the B.C.B.S. of the river see about ninety seventy one thousand at this point that's forty years ago or even sooner. Forty years along and the discharges get yourself a real milk and some of the paper mill to start to search for your plants so we've got to go read it up reduce drug use and what we call it direct this drug for the cameras goes we plan for transplants are usually not designed or good remove these compounds will do distort our bypass some time into the river. Seriously just deal with up our natural resources just the way to do this with a real bit about seven hundred dollars out of P.C.B. early and only about ten percent of that are still really knows where the salt Quest is where the other ninety percent go done and all the great talent like me personally but the cleanup design. That's sixty six thousand pounds a reformation still be left in the river the ten percent or so Bill left behind were put here like their fish have suffered if I agreed to that effect on the more particularly my home so they said. You know or you're not supposed to be this certain people are not putting this on the river like in this building that Michael B.C.B.S. theory. He set up a pool cleaner said look you got very good news out of a lie on top of a guy thing. So you go over above this a lot of them like got to go through the things up to the very start and no idea it was coming. Probably never resort to from a few hundred pounds to be very very impatient to be transported through a great day like going into some of the plumes around us out of a mission of maybe to you by this point because we showed good example of what we're going to do your your angry. Come on your side not to be around there tonight to go through record decision you should go. You have to be required remediation of all the risks of the P.D.P. The one milligram police. I mean there's an order to comply with the regular safety of the sediment in the settlements have to be to go one member have to be with a threat to prove the real problem however pesticides darkens if you're gone for a long time member of the well this is a picture on the great board because of the way the animal part of the bridge. That's a great bucket there was like a we dropped it down into the water plant get the sediment the explosion contamination out of the something to work on Clover react to whatever you didn't good mechanical grip put up with or go running out the theory of the whole way. Well you could actually see your Bloomberg family nation moving down the river where you brought the bucket wrong then polished selling the drugs those of us that are bored forgot to take it somewhere who will process it continue to drain really poor and poor so the problem is if you want to get a break. You can't do it anybody. Why I mean printing what I say to the general revenues first for immigration practical Boy this traction on the side of the transport family yourself are a major major problem. There's guys down here watching water for help from wherever they were trained great together. Friends who would like to get out of school get a job. There's a job available for you right there in the park by heart here. I've got a craving involved. Actually all going through the the still money and sucking up a slurry on the set of US A Gary a water into a pipe and pump it into some sort of profit location so not only a cleaner process but it's still hard because we got a great bargain flow from dilution of some of the already low and regular quoting here with me for the more your treaty changes radically from hour to hour day to day what level would become to you when you were three and a great way for you for your normal had to be treated and returned back to the rural life where you used to use high growing area water separated more of the server river water just you're going to burn it back into the river or there's an example provide a. Really don't know or Parker before he went full scale just to see what the content would look like in the bread water the bill he was not to Barack to be sent out I really want to die. Bill that some of that stuff too bad it turned to be your you know you're going in. I don't know the situation for that I was selling point. A few times to the criteria for ammonia burst water pipe when I pulled the fifty percent out dining to the tops of the cops it's a crime to report for stuff. Not one by rebirth of burglary. We did observe however the love of the highest we've heard was too high for one the right guy to talk to about three point zero or one N.P.C. be in the same time talking so this water that cannot expect to just distort back into a tree to tree is true fish stated technicality theory I love you are here to play with the reporting. Regulations of the water zone there are several there so you got the difference there are five to the sublime Cypress done to my home more than that in addition to just like bridges driving from the river to Green Bay to migrate and like this you go to the great lakes rivers regulated under international treaty between then and the United States where you got your national government required and they're happy standby that what you're doing is appropriate for the part of the great law and just. Well you don't want to call the standard with them. You're a stand or point criteria were already built for learning which says the work was already on a spec and you know what it was trying to get some coffee. This drug company and the like get some more work than they were dish soap dish to the back and go inside to hear your views about you know ready to go to work during her getting offers of a little over ten a large amount of the traditional work on things done for the president to be big of a part of your most printed the story that one make you can write whatever you guy just drive something that you know where the water and you may not be able to line up or think that it will be the second half of you not going to be yourself. Everybody is focused on that very thing knowing that they were just going to build your will do it because the problem will be at five o'clock to five in the Permian Basin five reverse them live happy and this is why most of these operate remedial operations end up lying on their site the river going to accept so many health certain material for a day or more. And that's going to be your current and you will see how to translate because I can still like that there are some wires exemptions I'm going to get to intercept I believe the supervisor says that what I do in the river at their apartment would you know out to the great river. I think I have never heard it referred to down in the water. But what if you take out a water tree. We're back. Yet you haven't really thought here are proud when you get through all those years of bottom line and wanted to apply whatever best thing you know I didn't get to the extent that you could but then place. Operated for pay for and then where the water boarding standards gave you. She you have to slow the rate of remediation in order to pull a man with a support not speed to have some of the panic here but what then does slow down the process and makes what could be a five year private opinion and that's how the marker next to recovery. Sometimes gets elected because about time to slow down enough to not exceed just some of the capacity of the river here so many years that you're just about approaching the mark of natural recovery time. That's a bitter pill to swallow when you're away leaving do nothing to get the job done and moving on usually are not going to read your way for treatment. If you're just so you feel quite the waste water boy remains are very important your big day the way for a generation raised to basically balance in ten thousand gallons per cubic yard or seven take out the jury car. And there it is about four thousand pounds that means you take down thousand cubic yards which is not a lot for me down the right there are three. But we're not talking about fall through the whole time because of the way for polluter quite enough but in very small concentration lost their way there was one of those big was the future interfere with video posters that appear. Our process for example on native competing on board and if we talk about their civil war. Some of them have this is an example of that I brought a British caller courage and experience down into the service and a rotating customer have sucked up the worry of the cinemas and water this hot this high this part because I was part of the central processing going out. Let me just say one thing because again going to trade down to the for the contamination after the car. Yes but there's always a layer of how they can themselves left behind exposed to the water until we come back and make our second or third or fourth Test this is I get bored with our you know this but you're right there are huge tented down through the water column story room today just to cut through the part we're popped up into the transfer like one of the transfer pipeline of the guard back this is a pretty quiet one hundred but this is part of its own Landmark to get a bigger part of this pipeline dogfish. All the way to the bridge where the bridge here has got where the pipeline can be just a mile off guard prepared to begin to move down the river. So there really are like just very limited number of both on the for me. You're right here you're safe tonight will actually have been a solid fire mostly everything in the record and I probably know all the you know the less than ten milligrams polluter. That's achievable but because of their similar to the capacity of the river for our demand they put American lives up to thirteen hundred pounds per day to no regulator thirteen hundred pounds a day is about five a gallon. There are about ten thousand gallons of what that's said paying process more than ten thousand gallons then that's still a pretty victory but there's another kicker here Margaret I can hold out with a quote for one more try. But I have a lot of the future. Delusion Rachel what the government actually decided is required. There are people really do you tend to put out a big computer by supplier with a lot of tears or organic and pumped through it all right so that there were there was no profits on the phone there were just burst of media trying to do the whole river by diluted down through various laid up for the night one for the right leaders saying look we're not only what I say or I don't think Mercury. That's a look or think we want to Nandigram for a leader. I don't I mean you just you're right right partner hearing. Forty years I've never seen a distorted doctor or watched him point to Nandigram leader and he should be listened to thank you letters take time to do what they're very good at that point one point five five we can find. Here for him because the only issue is concern and the fact that they were good appears I want you across the river to KERSTI. Impact for the future ahead downgraded the minimum flow of three thousand young men soft actively between that user flowing and this one right here you had to operate the brain fried himself bit at a restaurant shut down lower or higher your shutdown. So you had an upper and lower bound rate never boundary because of the you know this manslaughter or boundary because the deed operated accuser no one to try to pick the river the best. This is the breaking story for you the last it was very vocal not as a victory by a guy who said the formulation sedimentation sandhill trace back to a great thread and we're back to car sort of car to look at the destroyed. River of the future and interest suddenly there was a treatment we have developed for evolve and to go with the regulatory authorities and they actually incorporated that pretty much into a bell or in a straightforward step with a legal document that the government and the responsible parties sign. What it said is this is what you're going to say but no deviation the slide from the treatment of that story that all of them swearing result of voter. Pressure was the filter approach you can see all collected in your former life building take the picture but during the four years of the left really your four years treatment plan Cross at one point. I'll be in the yard but I think your yard bridge still generated almost eight hundred thousand times. We'll take a bit of land. OK where's the trucks transporting that will take to the landfill was a continuous parade of very large trucks and one of the things I would like to be done for good. Now rather than our current How many crediting the caliper likely associated with the trailer for the everyplace from this plan going. You know think about that in addition to the dredging about one hundred fifty acres of the wrong we're going to pay out our races over Currently I can't discuss kind of between the people who are paying for the company and the river agreed to them for this needed to be completed. I thought in my view not to have to come back here to talk about right now is more than good that they are Bottom line our regular I want to know that no mediation technologies are set up that does not a rigid longer rate we have I think to do it in situ because a stabilization may turn out to be good just figure out the right way to do it how to carve it or facilitate progression. There's always some residual temptation or bind it remains to be passably just mark really hard by visual review actions such as sucking up more water caught up for the version of the families of those around the waterfall. I mean the figure was. We can continue your order and we need your more about war or your buying or trading that many sums up the radio program. Well here's a couple of just to give you an idea when I put up was in river. They set up our standard for bridge which has been taken up by or whatever and then every. OK to be leader down to someone about offering that me the other grouping in the first of all there was a vibrant place with them out after a many forwarders at several Well this was a good idea and any time they stayed at the fire but it never really got shut down. Mark for a second organizer started the problem. Come on to the left around P.C.B. the time we got the lab results back did very well that was what I mean for a good idea but it wasn't quite up to the battle like this on the our property they actually were putting in moving downstream with the literally bar to buy on any time the big guys have shut down the flow so they didn't worry about what with all the sediment through the entire place eight of them may forever. Really be going through fire or river vision. Maybe if you're ready to apply to say. Great I get really cold and her daughter very highly rated Bruce I would be better able to make more right focusing on our limited very imperfect real offer but we have a long way to go. I think I have been proven so in our ability to deal with this riddle for years real family. You have got to come out of your birth please research my head repeatedly about ways to do that. Thank you very much. You know my prayers go out your friend John are coming along. I know some of your very vocal right like that but yes I think there are a lot of risk analysis done to figure out what would happen if you got there but it does believe the places that are down there that get the people who are lucky enough to get there. Really. Yeah but I'm just wondering if you're talking about hypotheticals. You know fresh out of it's been very good stuff so I don't know man. It sounds like some people are making a little money doing this stuff and for the people willing to do it but we do question I think that you know they are just you know what they're going to work towards their sometimes. Congress and what we do we're doing very very mature you should have a mission going for that mission to clean up your brother but as you're seeing today I would never wear it but it's a well dressed up all the tradition. Listen to the people who elected good for America. So you've got your initiative there is a look very fire to your car or fire for a bit here very very much for roadwork tartlet you are afraid that our children will get out now is the engineer would say you sure you really want to do. There will be a big big problem many Unocal or whatever so many forces that are terrifying don't do. He said that in the public hearing privately that assuming they're all very very very tough border guards were if you're going to go for them to do it so quick to them or when we don't have it all became totally to your mind. No one fired the rest or off your face but our very best one. What By the way you want to ask me if we're ever violated or this drug. Sure not all that we did every time we did you know the headlines in the Green Bay You played one after the way that you know one of the babysitting for the book was exactly what the Congress really thought YES More more. Must come a point where the ones you really love hearing that point. Yeah there are ways kind of help with the never forget that you thing is just a way to try to be don't let that fool possibly please others down there. I mean that's all. Here you have no right or we know you're made of the whole cake make it to you to show all those kinds of but if you're still stuck the natural process to face now would point out that if there was water torture the law. Why aren't those who did all the federal law work or would like very very very good result don't sit around waiting for a body recovered to go into war. There's no rule like that. So there's that driving force. You've got a little low impact water. Dear. You're so sorry for your want to believe God you could say what they did better but I know this is a little early. Very good got a lot of really good regret or just got it right for the first time really the right. This kind of thing and the complexity of the decision process or the rationale for what you're doing somehow gets overwhelmed by the thing we all think what I would look for in the room to make your best we're very first to suffer through this. We're going to go a long time left unchallenged you have to do your bit not to go on the road will be with your quest to get the people. Well they don't want to support too much down they're going to defrost what they're going so what they're talking about his was the restoration for example of voters who are sick or something of the song waiting to stay right there in the general form with just one or make sure to visit their movies or support any time he did some way to really try to make it look mode I want to break it down certainly mark over your career track but a lot of these got a lot of people give up on what Michael what will they find might be a combination of chemical mark a high profile and the problem right now is in preparation say where I work at the jessamine you know what is it about. I want to see your brother a little bit by bit of the like everybody. So it's harder still to want to their motive now but there are all.
