ANY BIDS ON CLEAN UP?

I'm thinking about how Mountain Creek Lake in Dallas can be cleaned up-vacuuming bottom sediments, incinerating PCBs, pumping and treating water, etc. I know many say it can't be done, but having read about toxic lakes in other states and even in China, I see that it can. Yes, a clean-up would be very expensive; but at least four liable parties need to worry about that. I'm also thinking about job creation through a safe clean up done by a top notch company, with millions of dollars in wages bringing more immediate revenue to Dallas than the bridges and hotels we desire here. I believe that toxic sites can be addressed properly with worker protection, good wages and health benefits because it's being done other places. The days of getting uneducated, underpaid people to do dangerous jobs should be over.
We have a lake that is simply not acceptable to citizens who desire a high quality life. Wouldn't it be a nice to have procured federal stimulus money to help put people to work and get this problem fixed? I'm not talking about throwing money at a problem; I am talking about safety, quality, and fairness that are worth the expense. By the way, what was stimulus money spent on that was more important than our water, air, and soil? And what technologies for clean up have our city and state officials evaluated and compared as they try to improve Oak Cliff/West Dallas? Has any company ever been allowed to study the full extent of the damage here and even tentatively bid on the lake clean up job? I imagine not since Dallas has passed the MCL problem on to the state of Texas, and the state has decided to do nothing to the lake itself.
When government says "No, can't be done, too expensive"-and the problem is mainly their fault to begin with; and people who live near a polluted site can't fight the government they need for social program grants, college tuition loans, welfare and clinics...DO WE HAVE A PROBLEM? Won't this situation go on forever until it's viewed with fresh, independent eyes? We need the beloved values of our capitalistic society here and now-entrepreneurship and competition - both dependent on scientific advancement. And we need our universities to be free from government and corporate pressure. Often universities, dependent on the polluters for funding, back off when they could be of great service. So, any technical innovations, strategies or bids on clean up? Anyone really know the true extent of the problem in Mountain Creek Lake?
