The Bureau of Reclamation (Reclamation), a leading federal agency in water management, has initiated a three-phase prize challenge, offering a total of $550,000, to solicit groundbreaking solutions for preventing the transport of aquatic invasive species (AIS) in raw water entering and exiting watercraft ballast compartments. This critical initiative, managed by yet2 and facilitated by the expertise of NASA’s Center of Excellence for Collaborative Innovation (CoECI) and its NASA Tournament Lab, aims to safeguard vital water delivery and hydropower infrastructure across the Western United States from the pervasive and costly threat posed by organisms such as quagga, zebra, and golden mussels. The challenge officially opened on February 26, 2026, with concept papers for Phase 1 due by May 29, 2026.
The Escalating Threat of Aquatic Invasive Species
Aquatic invasive species represent one of the most significant environmental and economic threats to freshwater ecosystems and infrastructure globally. These non-native organisms, once introduced to new environments, can outcompete native species, disrupt food webs, alter water chemistry, and cause widespread ecological and economic damage. The challenge specifically targets quagga, zebra, and golden mussels, which are particularly notorious for their biofouling capabilities.
Zebra mussels ( Dreissena polymorpha ) and quagga mussels ( Dreissena rostriformis bugensis ) are freshwater bivalves native to Eastern Europe and Western Asia. They were first detected in the Great Lakes region of North America in the late 1980s, likely transported via the ballast water of transoceanic ships. Since then, they have spread rapidly across the continent, primarily through recreational boating and water transfers, colonizing lakes, rivers, and interconnected waterways. Golden mussels ( Limnoperna fortunei ), native to Southeast Asia, pose a similar threat, particularly in South America, and represent a significant concern for potential future introductions to North American waters.
These mussels attach to hard surfaces, forming dense colonies that can clog pipes, screens, and turbines, significantly impairing the function of water intake systems, hydroelectric power plants, and irrigation infrastructure. The financial burden associated with monitoring, prevention, and control of these mussels in the United States alone is estimated to be in the billions of dollars annually, encompassing increased maintenance costs, reduced operational efficiency, and damage to recreational equipment and facilities. Ecologically, their filter-feeding activities can drastically alter water clarity, remove phytoplankton essential for native species, and accumulate toxins, leading to cascading effects throughout the aquatic food web and threatening biodiversity.
Bureau of Reclamation’s Vulnerability and Mission
The Bureau of Reclamation operates a vast and complex network of dams, power plants, canals, and reservoirs across 17 Western states, providing water to more than 31 million people and irrigating 10 million acres of farmland. It is also the second-largest producer of hydroelectric power in the Western United States. The integrity and efficient operation of this infrastructure are paramount to the economic stability, agricultural productivity, and water security of the region.
Reclamation’s infrastructure is particularly vulnerable to AIS. The intricate network of pipes, gates, and turbines offers ideal habitats for mussel colonization. Past and ongoing infestations have already demonstrated the severe impact: reduced water flow, increased friction in pipelines, decreased efficiency of hydroelectric turbines, and significantly higher operational and maintenance costs due to the need for manual removal, chemical treatments, and specialized coatings. A spokesperson for the Bureau of Reclamation, who preferred to remain unnamed due to ongoing sensitive project discussions, emphasized the critical nature of the challenge: "Protecting our water delivery and hydropower assets from invasive species is not merely a matter of maintenance; it’s fundamental to our mission of delivering water and power reliably to millions. The costs, both financial and environmental, of inaction are simply too high. We are actively seeking innovative, scalable, and environmentally sound solutions."
The Strategic Role of Crowdsourcing and NASA CoECI
The decision to leverage a crowdsourcing prize challenge underscores a growing trend within federal agencies to tap into a wider pool of global expertise and accelerate innovation. NASA’s Center of Excellence for Collaborative Innovation (CoECI) plays a pivotal role in this strategy. Established to assist federal agencies in utilizing open innovation and crowdsourcing, CoECI provides the necessary expertise, infrastructure, and contract capabilities through its NASA Tournament Lab (NTL). The NTL acts as a facilitator, enabling agencies like Reclamation to launch external challenges and access a diverse community of problem-solvers, including individuals, small businesses, academic institutions, and international experts, who might not typically engage with traditional government contracting processes.
The crowdsourcing model offers several advantages over conventional research and development pathways:
- Access to Diverse Perspectives: It brings together a broad range of scientific, engineering, and entrepreneurial minds, fostering interdisciplinary solutions.
- Rapid Prototyping and Testing: Challenges can be structured to quickly move from concept to validated prototype, accelerating the development cycle.
- Performance-Based Funding: Prizes are awarded only for successful solutions, making it a highly cost-effective approach.
- Reduced Bureaucracy: The process can often bypass lengthy procurement cycles, allowing for quicker problem-solving.
A representative from NASA CoECI, Dr. Emily Vance, highlighted the organization’s commitment to inter-agency collaboration: "Our mission at CoECI is to empower federal agencies to harness the power of open innovation. The challenge launched by the Bureau of Reclamation is a prime example of how crowdsourcing can address complex, real-world problems that have significant national impact. By opening this challenge, Reclamation isn’t just seeking a solution; they’re inviting the world’s brightest minds to contribute to safeguarding our nation’s critical water infrastructure."
Challenge Structure and Timeline
The "Halting the Hitchhiker" challenge, managed by the open innovation firm yet2, is structured into three distinct phases, designed to progressively refine and validate proposed solutions:
- Phase 1: Concept Papers (Open February 26, 2026; Due May 29, 2026)
- This initial phase invites innovators to submit detailed concept papers outlining their proposed approaches. Submissions should describe the scientific and technical basis of their solution, its novelty, feasibility, potential effectiveness against AIS (killing, excluding, or inactivating), scalability, environmental impact considerations, and estimated development pathway. A panel of experts will review these submissions, selecting the most promising concepts to advance.
- Phase 2: Prototype Development and Testing (Inferred)
- Teams selected from Phase 1 would typically receive seed funding and proceed to develop prototypes or detailed engineering designs. This phase often involves laboratory testing or simulated environments to demonstrate the efficacy and safety of the proposed solutions under controlled conditions. Rigorous evaluation criteria would assess performance, reliability, and readiness for real-world application.
- Phase 3: Field Demonstration and Validation (Inferred)
- The final phase would involve deploying and testing the most successful prototypes in a near-operational or actual field environment. This could entail pilot projects at Reclamation facilities or other relevant sites, assessing the solution’s effectiveness in preventing AIS transport in real-world ballast water conditions, its integration with existing systems, and its long-term viability.
The total prize purse of $550,000 will be distributed across these phases, incentivizing continued development and rewarding successful outcomes at each stage. The structure encourages innovative ideas from the outset while ensuring that only the most viable and effective solutions progress to demonstration.
Expected Innovations and Impact
The challenge explicitly seeks novel approaches that can kill, exclude, or inactivate AIS within watercraft ballast compartments. This broad scope encourages a wide array of potential technologies, which could include:
- Physical Methods: Advanced filtration systems, acoustic deterrents, thermal treatments (heating/cooling), or hydrodynamic cavitation.
- Chemical Methods: Environmentally benign biocides, targeted anti-fouling coatings, or novel chemical treatments that quickly degrade after application.
- Biological Methods: Use of natural predators, pathogens, or genetic approaches, carefully controlled to avoid unintended ecological consequences.
- Integrated Systems: Combinations of the above, perhaps leveraging artificial intelligence or machine learning for real-time detection and treatment.
The successful identification and implementation of such solutions would have profound implications. For the Bureau of Reclamation, it would mean enhanced operational efficiency, reduced maintenance costs, extended infrastructure lifespan, and greater reliability in water and power delivery. More broadly, it would contribute significantly to national water security, protect delicate aquatic ecosystems, and preserve recreational opportunities.
Dr. Alan Reed, an environmental scientist specializing in invasive species at a leading university, commented on the significance: "This challenge by Reclamation represents a critical pivot towards proactive defense. Current methods are often reactive, expensive, and sometimes environmentally intrusive. A truly innovative solution for ballast water management could be a game-changer, not just for the Western U.S. but potentially for global efforts to curb invasive species spread. The collaboration with NASA’s crowdsourcing platform further elevates the potential for a breakthrough."
