David M. Chambers, Ph.D., P. Geop.

Dr. Chambers is the founder and president of the Center for Science in Public Participation, a non-profit corporation formed to provide technical assistance on mining and water quality to public interest groups and tribal governments.

David Chambers has 40 years of experience in mineral exploration and development – 15 years of technical and management experience in the mineral exploration industry, and for the past 25 years he has served as an advisor on the environmental effects of mining projects both nationally and internationally. He has Professional Engineering Degree in Physics from the Colorado School of Mines, a Master of Science Degree in Engineering from the University of California at Berkeley, and is a registered professional geophysicist in California (# GP 972). Dr. Chambers received his Ph.D. in Environmental Planning from Berkeley where his doctoral dissertation analyzed the U.S. Forest Service’s efforts to plan for and manage minerals on the National Forests...

He has provided technical assistance to public interest groups and tribal governments on proposed, operating, and abandoned mines in Alaska, Arizona, California, Colorado, Idaho, Michigan, Minnesota, Missouri, Montana, Nevada, Oregon, South Carolina, South Dakota, Utah, Washington, Wisconsin, Canada (British Columbia, Ontario, Labrador, Yukon), Kyrgyzstan, and Northern Ireland. This assistance has included review of underground and open pit mine design, seismic stability for tailings dams, waste rock facilities design, water quality monitoring, water treatment facility design, reclamation planning, and financial assurance for mine closure. This has included the review of dozens of environmental impact studies and included analyzing the potential adverse affects on surface and groundwater quality of acid mine drainage and metals leaching from mine point discharges and seepage from mine waste storage facilities, and on proposing alternative methodologies to avoid these impacts.

Dr. Chambers has also provided technical assistance to tribal governments and public interest groups in negotiating with mine owners, mine developers, and federal and state regulators, to assist these parties in understanding the major technical implications of specific mining projects, and in providing alternatives that would lead to more environmentally responsible development. He has played a key role in negotiating complex agreements, including alternative development plans for several mine proposals in Alaska, technical studies related to EPA placer mining regulation, efforts by the mining industry and NGOs to research and regulate marine mine waste disposal, and a joint industry-NGO international effort to develop a process to define and measure performance for responsible mining practices.

Dr. Chambers has worked with the State of Alaska Departments of Natural Resources and Environmental Conservation on mining, reclamation, cyanide and solid waste regulations. He has been a member of the University of Alaska-Fairbanks School of Mineral Engineering Advisory Board; a member of the Western Governors’ Association Abandoned Mine Waste Working Group; and, a member of the EPA’s RCRA Policy Dialogue Committee, a group of industry, environmental and government representatives who worked to develop regulations for mining wastes under the authority of RCRA Subtitle D.

Kendra Zamzow, Ph.D.

Dr. Zamzow is an environmental geochemist and is the Alaska representative for the Center for Science in Public Participation. She has a Ph.D. in Environmental Chemistry from the University of Nevada, Reno and a B.A. in Molecular and Cellular Biology from Humboldt State University, California. At UNR she operated a sulfate-reducing field bioreactor treating mine water discharge at an abandoned copper mine Superfund site, and provided the laboratory water chemistry analysis for sulfate, metals, and alkalinity. Bioreactor research examined utilization of industrial waste as feed for bacteria, sulfide toxicity in bacteria, and biological removal of sulfate and metals to MCL guidelines. Molecular techniques were utilized to track microbial populations and identify phylogenies in the bioreactor under optimal and stress conditions.

Dr. Zamzow completed a Science and Policy fellowship with the American Association for the Advancement of Science working with the EPA, Office of Research and Development, Office of Science Policy, in Washington, D.C. from August 15, 2012, through December 31, 2013.  Dr. Zamzow has lectured in graduate level classes on Environmental Toxicology and Analysis of Contaminants, and taught community college classes in Microbiology, Chemistry, and Biology. She has 5 years experience as a contract fisheries biologist with Alaska Department of Fish and Game, the Forest Service, and the National Marine Fisheries Service, and was the Field Coordinator for marine mammal biologists in False Pass and Prince William Sound, Alaska for 2 years. Kendra has 7 years experience in laboratories and in contaminant research in Alaska, California, and Nevada.

Stuart M. Levit, M.S., J.D.

Stu worked for the Montana Department of State Lands, Abandoned Mine Reclamation Bureau as a Land Reclamation Specialist, where he designed mine reclamation project plans, focusing on water quality and watershed improvement, hard rock mines, acid mine drainage prevention and treatment, artificial wetlands, and NEPA and Superfund (state and federal) compliance.

After completing law school at the University of Montana, he was a clerk for the Montana Supreme Court. He then worked as the water quality program Project Coordinator for the Coeur d’Alene Tribe in Idaho, where he represented the Tribe in a three-government program to reclaim the Coeur d’Alene Basin from past mining injuries and protect its resources from future environmental degradation. In this capacity, he facilitated effective tribal and public awareness and involvement in the Coeur d’Alene River cleanup process. He reviewed ongoing EPA cleanup activities associated with the Bunker Hill Superfund Site (Kellogg, Idaho), and provided support and project-specific tasks for joint tribal and federal Natural Resource Damage claim. He also drafted tribal water quality standards and classifications for Tribal Clean Water Act program application, and represented the Tribe in the regional and Tribal TMDL development processes...

Stu then was a Senior Staff Attorney for the Confederated Salish and Kootenai Tribes in Pablo, Montana, where he focused on environmental issues. He was the lead for injury determination/calculation in Tribal natural resources damage claim under CERCLA, which settled for over $18 million. He managed legal affairs for programs relating to Tribal Sovereignty and Treaty rights through environmental management, and developed and maintained Tribal Water Quality Program and Clean Water Act compliance. He represented Tribal Water Quality, Forestry, Fish and Wildlife, and Air Quality Departments; toxics and natural resources programs, and Mission Valley Power, the region’s power utility (tribally operated).

Stu represented CSP2 as a technical analyst to the Clark Fork Technical Assistance Committee for the Clark Fork River superfund sites (Anaconda Co./ARCO Butte-Milltown Dam). This Committee, funded with an EPA (Superfund) Technical Assistance Grant informed and assisted the public to understand and participate in the government’s and ARCO’s planning, permitting, and cleanup processes.

Stu was also Watershed Program Coordinator and Staff Attorney for American Wildlands, a conservation group in Bozeman, Montana, where he developed and implemented a framework and strategy for campaigns to protect high quality watersheds. This program required blending science and law to insure government agencies enforced environmental protection and land management laws. This project included working with the State of Montana on degraded water cleanup and protection (TMDL listing and development); endangered species protection (west slope cutthroat trout and Kootenai River burbot); and work on federal projects such as timber sales, Forest Plans, Travel Management Plans, and BLM Regional Management Plans.
