Meet The Alum Leadership Team
Director of Technical Services
As Director of Technical Services, Marc Bellaud is focused on advancing SOLitude’s momentum as an industry leader by upholding our commitment to continuous education, teamwork, a superior customer experience, and premium service offerings and technologies. From leading the charge on drone applications for remote or sensitive environments to enhancing our toolbox of water quality management solutions with Oxygen Saturation Technology, Marc is passionate about bringing new technologies to SOLitude. Throughout his 27-year career, Marc has been actively involved in cultivating the science of aquatics as a good steward and widely-respected thought leader. His passion for protecting water inspires his guidance of the SOLitude team.
Marc graduated from the University of Vermont with a degree in biological sciences and a concentration in natural resources. He worked for two non-profit organizations before joining the aquatics industry in 1993. His knowledge and responsibilities as a field biologist quickly expanded, culminating in his promotion to SOLitude’s company leadership team in 2013.
Marc has extensive experience designing and leading integrated aquatic plant management programs throughout the Northeast. He has authored dozens of lake management plans and feasibility studies and is a contributing author and co-editor for the third edition of the BMP Manual produced by the Aquatic Ecosystem Research Foundation (AERF). He regularly shares his knowledge and experience as a presenter and speaker at industry conferences.
Marc is a Past-President and Director of the Northeast Aquatic Plant Management Society (NEAPMS) and has remained involved with the organization since it was initially founded. Marc also served as a Director of the New York State Aquatic Managers Association (NYSAMA). He is actively involved with several state organizations focused on lake management issues. In 2006, Marc received the SePRO Applicator of the Year award.
Marc was born and raised in New Hampshire. From an early age, he developed a love of the outdoors where he grew up skiing, fishing, playing ice hockey, and spending summers at Squam Lake, which remains one of his favorite places to visit. Outside of work, he enjoys spending time with his wife, two sons, and the family dog. He and his family are very active with sports and over the years Marc has dedicated much of his time to coaching youth hockey and assisting with their local Boy Scout troop.

John Holz, Ph.D.
Senior Limnologist, Alum Expert
Dr. Holz has over 20 years of experience in surface water quality and aquatic habitat management and research. While earning his Ph.D. from the University of Nebraska-Lincoln (UNL), Dr. Holz’s research advanced our understanding of water resource issues and developed improved management tools for lakes, streams and watersheds, including assessing and predicting the response of waterbodies to pollutants and the effectiveness of restoration techniques. Dr. Holz conducted research that advanced our ability to address numerous unique water quality challenges and pollutant effects.
Specific areas of expertise include lake restoration and management, watershed management, biological indicators of water quality, phytoplankton ecology and management, nutrient inactivation (alum), determination of appropriate water quality goals, nutrient criteria development, water quality monitoring, water quality modeling, internal phosphorus loading, and determining the effectiveness of TMDL’s using water quality and biological information.
Dr. Holz was honored for his alum research advancements by the North American Lake Management Society when he received their Technical Excellence Award in recognition for Outstanding Research in Lake Restoration, Protection and Management.
As a faculty member at UNL, Dr. Holz obtained over $8 million in funding to support water quality research, authored over 20 publications, taught courses in Limnology (the study of lakes and streams) and Lake and Reservoir Restoration, and served as a technical advisor to the U.S. Environmental Protection Agency (EPA) on water quality management issues in the U.S. Dr. Holz is a recognized leader in water quality/aquatic habitat management.
Senior Limnologist, Alum Expert
Tadd Barrow has over 15 years of experience in fisheries, surface water quality, aquatic habitat management, and research. While earning his M.S. from the University of Nebraska-Lincoln (UNL), Tadd’s research advanced our understanding of the management of sensitive fish species related to unique water quality stressors, including assessing and predicting the response of fishes to pollutants and the available aquatic biota. He conducted research that advanced our ability to address numerous unique water quality challenges and pollutant effects.
Specific areas of expertise include communication with public and private agencies and businesses discussing lake ecology and restoration and management, watershed management, biological indicators of water quality, phytoplankton ecology and management, nutrient inactivation (alum), determination of appropriate water quality goals, nutrient criteria development, water quality monitoring, water quality modeling, internal phosphorus loading, and determining impacts of toxic algae using water quality and biological information.
Tadd was honored for these achievements by the 1) Environmental Council of the States Program Innovation Award and 2) Nebraska Rural Development Commission receiving awards in recognition for work as part of the Community Lakes Enhancement and Restoration (CLEAR) program.
As a faculty member at UNL, Tadd obtained $6 million in funding to support water quality research, authored over 16 publications, and lectured courses in Limnology (the study of lakes and streams) and Lake and Reservoir Restoration. He supervised the analytical water chemistry lab and established the nation’s first toxic algal response programs for private and public lakes. Tadd is also a graduate of the National Extension Leadership and Development, which serves to build leadership and provide University Extension leaders the vision, courage and tools to lead in a changing world. Tadd is a recognized leader in water quality / aquatic habitat management and toxic algae assessment.
