I find this funny (?), maybe "interesting" (?) but I find it "something" to be certain....
So let's say that we have this dirty worsh water. Let's say that we have 600 gallons of it - like shown here....
.. and it's just too "contaminated" (with what?) to dump down the city sewer, or worse yet - out in the driveway (where vee-hickles drip oil and ethylene glycol every day - but we don't seem too concerned aboot that...)
So - now we go and fetch us one of those evaporator units. We burn up X foot/3 of natural gas, or Y KW of hydro and we evap it all away.
So - now what?
Where did all those "contaminates" (real, or perceived) go?
I worsh alum, brass, and various steels. How many of y'all are OK with dumping your chips ("drained" of oil/coolant) in the dumpster and sending it to the landfill. Where's the diff?
The driveway in front of my G-pa's barn, where he use'ta toss used engine oil out in the driveway by the bucket load at least to the mid 80's, has had grass growing from non-use for decades now.
I see spots near the diesel pump that kills the grass for a few yrs after a spill. I find it interesting that there is a kill spot in the center, surrounded by the greenest grass around. It's not a case of kill zone slowly and slightly growing vegetation as you go out from ground zero like the Tunguska zone....
So - let's say that we evap'd off 595 gallons of liquid ... and we find that we have a bucket of dry sediment left. Is that scary? What is it that's scary? Dissolved irons? Alum fines? Prolly some amounts of floor dry or just plain dirt dust...
Did some refined plutonium find it's way in there? (I doo have a cpl centrifuges here, so ... ???)
Have y'all ever been involved with digging up an old "leaking" fuel tank?
The part that I find "funny" is that I buy into it a fair amount myself.
I am actually pretty "green" as much as I hate to be aligned with that crowd.
Actually - another thing that I find interesting is that one of the most concerning "fields of interest" that the cities tend to watch for in the sewer is Ph levels. Yeah, you may be dumping Ph5, but the guy accrost the street is dumping Ph9. But each of you need to correct it to 7 before dumping or you get in trouble. .. and they doo monitor that monthly with certain industries.
There is a Superfund site where I have ridden snowmachine on occasion. It's an old gold mine that was ran around the turn of the century (the last one eh?) and then aggin as late as (?) The 80's (?) I think? Apparently enough cyanide had found it's way into the crick, and there are no fishies in there for 7 miles downstream. This site is almost exactly on top of the Continental Divide (you can walk to it from there) so - I'm not sure how man fishies would be expected to be in a crick that far upstream, as I would fully expect that it goes dry several times each yr. (It's at the top of the drainage) But - none-the-less, that seems to be a little scarier and "real" than some dissolved steel fines...
I got'ta wonder how much oil and ??? goes into the leach bed from worshing my britches in a years time?
How about the oils and ?? that come from the rags when they get worshed?
