Saddiegirl, outstanding experiment and posting of the results. I am sure this will be beneficial to a lot of us with seeping ponds. Was the additional material added as it was in the initial trial? ie, A with additional bentonite on top, D with additional Kitty litter mixed in, and C with additional litter on top? What were the results with C, or did D have additional product added on top. Lastly, were the last tests with new dry soil?

again thanks.
