Hey Mike,
We have a 4.5 acre leaking pond. It is in compacted clay soil. The NRD is doing an engineering study on it now. It appears that the bottom of the pond is in the watertable and we think we lose our water into that ( because it stablizes at a low level). We are thinking about ESS-13- added directly to the water. I'd like to see some of your info or if anybody else has had some experience with this product- please let me know.

Brad
