BC-Oscillatoria agardhii was the main one. I plan to wirte this project up for future water supply work. I may get you a copy for review since you know way more about copper than I even want to know. The Rep from EarthTec seemed to think our subsurface application would work just as good as injecting. No complaints here, it worked and was easier that way. Thanks, Greg

P.S. heading to Iowa on a bowhunt. Will have to catch up on post when I get back.
