Sorry for taking so long to reply. We get our bentonite at the local co-op down here in Spring Hill. They sell it in 50lb bags so we aren't getting it by the truckload if that is what you need. The do sell the granulated bentonite and the powdered stuff. I don't have the guy's name who did our soil report. My dad was the one who met him at the pond the day he came out. He is out of Columbia, TN and actually builds ponds as well. He was very knowledgable and helpful. If you still are looking for someone, let me know and I'll track down his name and number. We have actually been digging out the dam this week and today rebuilt the bottom of the dam from the rock with compacted clay. Tomorrow we have some work to do with a dozer to put the site back together and we should be ready to fill it back up. Hopefully she holds water.
