During the first half of the last century Tarry water was a major problem to the coal gas producers, Gas Light & coke Company etc, Much research took place and a number of patents were culminated. It is well worth checking into some of these, one in particular I remember consisted of a tank containing "electrodes" which were used in the separation of suspended solids contained in the water passing through the tank rendering the water clean. I did print this patent and have it filed somewhere. I seem to remember offering the Patent number to this list some years ago when a similar discussion was in progress GFWHELL In a message dated 2/2/2013 7:30:51 P.M Eastern Standard Time, [email protected] writes:
How about the fact that the Nordics of yore used these wood tars as preservatives on their Viking ships? In most circles a wood preservative is assumed to be a substance that retards or eliminates microbial attacks leading to loss of structural integrity (probably the opposite goals of a composting operation).

Not saying your gasifier correspondent was making it up. But you would think the President of Myanmar would have better things to do than declare black water gasification leach ponds toxic sites Military juntas aren't well known for their environmental awareness. So why the concern about tar ponds people?
