This I-Corps project focuses on the development of a multifunctional, uncrewed aircraft system (UAS) to monitor water quality and detect harmful algal blooms (HABs). HABs in freshwater bodies pose significant threats to both public health and the environment. These blooms, often fueled by excess nutrients such as phosphorus, can produce toxins that affect water quality. The neurotoxins released by certain bacteria species can contaminate water supplies, posing serious risks to human health. The rapid growth of these blooms can disrupt local ecosystems, harm biodiversity, and impact agriculture, tourism, and recreation. Timely monitoring of HABs and water conditions is critical for taking prompt action to protect public health and water safety and security. Current in-situ and remote sensing methods are limited by factors such as high labor intensity and cost, inefficiency, and an inability to provide real-time monitoring. This sensing system facilitates the identification of nutrient sources and conditions that promote algal bloom formation, helping to inform targeted strategies for mitigating or preventing future outbreaks. Furthermore, by tracking HABs and measuring water condition parameters, this technology allows researchers and policymakers to evaluate the effects of these events on aquatic ecosystems, including potential changes in species composition and ecosystem services. This solution has the potential to enhance sensing efficiency, reduce cost, expand coverage, an
