    Here are three must-watch videos for anyone who wants to understand the science of mercury and dredging. The videos feature retired EPA scientist, Claudia Wise, who is not only a GPAA member but a suction dredge miner based in Oregon. She and Joseph Greene, also a retired EPA scientist, GPAA member and suction dredge miner in Oregon, have done great work in educating others about the BENEFITS of suction dredge mining and debunk the myths about mercury:

    Don’t let anyone tell you that dredging is harmful to fish. Dredging creates refugia and helps clean and loosen the gravels that salmon and other fish need to spawn. Dredging is not permitted during spawning season, so it benefits the fish and does not harm them or their habitat. Thank you once again  to both Joseph Greene and Claudia Wise! Keep up the good work and thanks for all you do to educate others.
