1. Introduction

Water quality monitoring is essential for ensuring the sustainability and safety of water resources, especially in regions prone to industrial activities and environmental hazards. The 2021 fuel leak at Pearl Harbor, O’ahu, involving the Red Hill Bulk Fuel Storage Facility, represents a significant case of environmental contamination, showing the need for robust monitoring and rapid response systems.

1.1 Background

Pearl Harbor has been a strategic military location for the United States since World War II, hosting significant naval activities. This harbor’s infrastructure includes the Red Hill Bulk Fuel Storage Facility, which poses potential environmental risks. On November 20, 2021, the Red Hill Bulk Fuel Storage Facility leaked approximately 19,000 gallons of jet fuel into the Pearl Harbor aquifer, the primary source of Oahu’s drinking water. This event directly contaminated the Red Hill well, affecting the Navy Water System, which provides water to about 93,000 people. Following this contamination, the State of Hawaiʻi Department of Health (HDOH) urged Navy Water System users to stop using tap water on November 30, 2021. As a result, approximately 93,000 individuals were potentially exposed to jet fuel for at least 10 days before transitioning to an alternative water source. The HDOH and Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (CDC/ATSDR) conducted surveys to assess the immediate physical and mental health impacts, revealing that 86% of respondents reported new or worsening symptoms since the spill. A follow-up survey in September 2022 indicated that 80% continued to experience symptoms. These findings demonstrate the severe and ongoing social, economic, and health impacts of the fuel leak, raising significant concerns about long-term consequences and the effectiveness of response measures [1]. The Environmental Protection Agency (EPA), in conjunction with the HDOH, mandated comprehensive environmental monitoring and remediation actions to address the contamination. Their efforts include the installation of groundwater monitoring wells, soil and water sampling, and the implementation of treatment systems to remove contaminants [2].

Silva shows the multifaceted benefits of wastewater treatment, including the protection of natural water sources from depletion, the provision of a sustainable water supply for domestic and industrial use, and the reduction of environmental pollution. By integrating innovative technologies and promoting efficient water reuse, wastewater treatment plays a crucial role in achieving sustainable water resource management and supporting overall environmental sustainability.

Historical data on fuel leaks, such as the Exxon Valdez oil spill (1989) and the Deepwater Horizon oil spill (2010), provide insights into the long-term environmental impacts of such incidents. Beyer et al. [7] provides a comprehensive review of the environmental impacts of the Deepwater Horizon oil spill, which constituted an ecosystem-level injury in the northern Gulf of Mexico. This study details how oil contamination affected deepwater habitats, coastal areas, and a wide range of marine organisms. The use of dispersants, in situ burning, and other response measures helped mitigate some of the impacts, but long-term effects on species like deep-sea corals, large fish, sea turtles, and cetaceans remain a concern. This paper emphasizes the need for continued monitoring and research to understand the full extent of the spill’s impact and to guide future oil spill response strategies. Wiens [8] provides an extensive examination of the environmental impact of the Exxon Valdez oil spill, drawing on nearly 25 years of scientific research. The Exxon Valdez oil spill released approximately 11 million gallons of crude oil into Prince William Sound, Alaska, severely affecting wildlife, including seabirds, sea otters, and fish populations. This book offers a multidisciplinary perspective, discussing the spill’s effects on various biota and ecosystems, the successes and failures of post-spill studies, and ongoing areas of disagreement. It covers the fate of the oil in the environment, including its behavior in the water column and on shorelines, the use of bioremediation, and the broader ecological risks and recovery processes. Bioremediation and other cleanup efforts were employed to mitigate the damage, but recovery has been slow, with some habitats and species still showing signs of distress decades later. This comprehensive analysis is crucial for understanding the importance of water quality monitoring and effective spill response strategies to manage and mitigate the impacts of such environmental disasters.

3. Methodologies for water quality monitoring

3.1 Sampling techniques

In the case of the Pearl Harbor fuel leak, various sampling techniques were employed to assess water quality. These included grab sampling, which involves collecting water samples at specific locations and times [9], and composite sampling, which aggregates multiple samples over a period to provide an average concentration of pollutants [10]. Grab samples were collected using sterilized bottles to ensure no contamination, while composite samples were taken using automatic samplers that combine water at regular intervals. Both methods were crucial in obtaining accurate and representative data on the extent of contamination. Analytical instruments such as gas chromatographs and mass spectrometers were used to detect and quantify the presence of hydrocarbons and other contaminants in the water samples [11]. These rigorous methodologies ensured the reliability and validity of the water quality assessment.

Schaeffer et al. [12] provides a detailed comparison of grab and composite sampling methods used in effluent monitoring. This paper discusses the theoretical and practical aspects of both techniques, showing the advantages and limitations of each. Grab sampling involves collecting individual samples at specific times, providing snapshots of water quality that can reveal variability and extreme values. Composite sampling, on the other hand, aggregates multiple subsamples over a period, offering an average that is useful for understanding overall process conditions but can obscure short-term fluctuations. The authors argue that while composite samples are economically favorable for routine monitoring and regulatory compliance due to lower analytical costs, grab samples offer superior information on process variability and are better suited for detecting extreme values and immediate issues. This study underscores the importance of selecting the appropriate sampling method based on the monitoring objectives and the specific environmental context.

3.2 Field equipment and remote sensing technologies

Advanced field equipment, such as portable water quality meters and spectrophotometers, were used to measure parameters like pH, dissolved oxygen, and hydrocarbon concentrations. Remote sensing technologies, including satellite imagery and drones, provided spatial data on the spread of contaminants, helping to identify affected areas and guide remediation efforts. Ahmad [13] provides an in-depth overview of the application of smart remote sensing networks in disaster management. This paper explores the critical role of remote sensing technologies in monitoring various environments, predicting disasters, and aiding in mitigation and recovery efforts. This study discusses the layered framework of remote sensing technology, which includes the sensing layer, network layer, data processing layer, and application layer. It shows the importance of advancements in each layer to enhance the overall intelligence and effectiveness of remote sensing systems. The integration of emerging technologies like the Internet of Things (IoT), cloud computing, and low-power wireless networks is highlighted as essential for the evolution and sustainability of remote sensing applications. This comprehensive analysis underscores the significance of remote sensing in providing timely and accurate data for disaster management, making it an invaluable resource for researchers and practitioners in the field. Vijayaraghavan et al. [14] provides an extensive review of the application of remote sensing and GIS technologies in disaster management. This paper discusses how these technologies have been used over the past five decades to manage natural disasters such as floods, earthquakes, and tropical cyclones, as well as man-made disasters like nuclear accidents and oil spills. It shows the advantages of using geospatial technologies for effective disaster management, including improved data collection, real-time monitoring, and enhanced decision-making capabilities. This review also identifies challenges related to data interoperability and visualization for decision-makers. This paper is important as it shows the critical role of remote sensing and GIS in mitigating the impacts of disasters, improving emergency response, and facilitating recovery efforts.

3.3 Artificial intelligence

Using Artificial Intelligence (AI) to monitor water quality is essential for several reasons.

This capability allows for real-time monitoring and early detection of water quality issues, enabling prompt intervention and management. Rana et al. [15] explores the application of AI techniques in monitoring and evaluating surface water quality. This study focuses on the use of machine learning models, specifically ANN and LSTM models, to predict and assess water quality parameters such as temperature, pH, dissolved oxygen, and turbidity. The authors demonstrate how these AI models can process large datasets efficiently, providing accurate predictions and real-time monitoring capabilities. This research is significant as it highlights the potential of AI to enhance traditional water quality monitoring methods, offering a more efficient and scalable approach to managing and protecting water resources. Shiri et al. [16] explores the development and application of various AI models for simulating groundwater quality parameters. This study evaluates several AI techniques, including Support Vector Machine (SVM) and ANN, and their hybrid forms combined with optimization algorithms like the Firefly Algorithm (FFA). This research demonstrates the effectiveness of these AI models in accurately predicting key water quality indicators such as electrical conductivity, sodium adsorption ratio, total dissolved solids, and sulfate concentrations. This paper is significant as it shows the potential of AI to enhance the precision and efficiency of water quality monitoring, providing valuable tools for environmental management and decision-making. Strobl and Robillard [17] provides an insightful overview of the application of various AI technologies in the monitoring of surface water quality. This paper reviews the potential of expert systems, ANNs, genetic algorithms (GAs), and fuzzy logic systems in enhancing the design and operation of water quality monitoring networks. These AI technologies are shown to offer significant advantages in terms of optimizing sampling locations and frequencies, handling large datasets with missing or uncertain data, and providing real-time, accurate water quality assessments. The authors highlight the importance of integrating AI techniques with traditional monitoring methods to achieve more efficient and cost-effective water quality management.

4. Impact of the fuel leak

4.1 Extent of water contamination

The primary source of contamination was identified as a ruptured underground fuel storage tank at Red Hill, which leaked thousands of gallons of fuel into the surrounding soil and groundwater. The contamination spread through subsurface pathways, affecting nearby water bodies and threatening drinking water supplies. Analysis of water samples revealed elevated levels of hydrocarbons, particularly benzene, toluene, ethylbenzene, and xylene (BTEX compounds). These contaminants exceeded safety thresholds set by the EPA, indicating severe pollution.

Jedra [18] reports on the discovery of extensive contamination at the Navy’s Red Hill fuel complex, showing a broader issue beyond a notable 2022 firefighting foam spill. State and federal regulators found that the Per- and Polyfluoroalkyl Substances (PFAS) levels in soil and groundwater around Red Hill exceeded EPA standards in multiple monitoring wells. These “forever chemicals” are persistent in the environment and pose significant health risks even in small amounts. The contamination affects an interconnected aquifer that supplies drinking water to both military and civilian populations. Regulators are calling for more frequent and comprehensive testing, as well as immediate investigations to address the widespread contamination, which may stem from both recent and historical chemical releases at the site

Figure 5 illustrates the proximity of the Red Hill Fuel Storage Facility to crucial water sources on O’ahu. Located just 100 feet above the Waimalu/Moanalua Aquifer, the facility comprises 20 massive fuel tanks connected by a system of underground tunnels and pipelines. The Red Hill Shaft, a key water source for the Joint Base Pearl Harbor-Hickam (JBPHH), lies a mere 2600 feet from the tanks, while the Halawa Shaft, providing water to urban Honolulu, is 5000 feet away. The historical and ongoing fuel leaks from the Red Hill facility pose a significant threat to these water supplies. Contaminants from the leaks can migrate through the porous volcanic rock into the aquifer, leading to drinking water contamination problems. The presence of fuel-laced water in the aquifer indicates that the contamination can travel and impact a broader area, putting at risk the health of approximately 400,000 residents who rely on this water source.

[21] discusses the crucial role of Early Warning Systems (EWS) in disaster risk reduction, emphasizing the importance of preparedness and robust monitoring systems. This chapter outlines an integrated approach to EWS, which includes hazard monitoring, risk assessment, forecasting, communication, and preparedness activities tailored to community needs. The authors show that effective EWS requires technological advancements in monitoring and forecasting, combined with educational drills, early alerts, and strong governance. They advocate for a holistic strategy that involves both top-down and bottom-up approaches, ensuring community engagement and leveraging local knowledge. Continuous monitoring, accurate risk communication, and regular drills are essential for significantly mitigating the impacts of environmental disasters. Vermiglio et al. [22] provides a comprehensive analysis of the impact of emerging technologies (ETs) on disaster management (DM) processes, particularly in improving performance across the preparedness, response, recovery, and mitigation phases. This study employs a systematic literature review, analyzing 69 publications using VOSviewer software for text mining and cluster visualization. Their findings reveal the significant role of ETs in enhancing preparedness and resilience in DM systems. Simulation and disaster risk reduction are identified as major fields where ETs can be effectively applied. The authors emphasize the importance of robust monitoring systems and preparedness measures enabled by ETs. Technologies such as big data, IoT, machine learning, AI, and remote sensing are shown to provide transformative potential for disaster management by improving data collection, decision-making, and performance measurement. These technologies facilitate timely and accurate information dissemination, which is crucial for effective preparedness and response, thereby enhancing the resilience and efficiency of systems to mitigate the impact of catastrophic events on communities and economies.

Khan et al. [23] conducts a comprehensive review of disaster management systems, focusing on flood control while addressing other natural disasters such as earthquakes and wildfires. This study advocates for the development of model-driven engineering approaches to simulate disaster scenarios and improve response planning. The authors underscore the necessity for continuous improvement and innovation in disaster management practices to mitigate the impacts of natural disasters effectively. This paper highlights the significance of incorporating interdisciplinary approaches and leveraging technological advancements to create resilient and adaptive disaster management systems. The authors suggest that future research should focus on developing integrated systems that combine various data sources and analytical techniques to enhance predictive capabilities and decision-making processes.

5.2 Implementing sustainable water use practices

Sustainable water use practices should be promoted to reduce the risk of contamination and ensure the long-term availability of clean water resources. This includes measures such as water conservation, pollution prevention, and the protection of natural water bodies from industrial activities. Santos et al. [24] examines sustainable water management practices in Brazil and Portugal, focusing on the integration of socio-economic and cultural dimensions. Key strategies include establishing robust legal frameworks, addressing socio-economic disparities to ensure inclusive water access, integrating cultural practices into modern management techniques, promoting efficient agricultural water use, and encouraging public participation. This article also highlights the role of digital transformation in optimizing water resource management through real-time monitoring and data analytics and emphasizes the need for adaptive strategies to enhance climate change resilience. Elleuch et al. [25] discusses strategies for achieving environmental sustainability through pollution prevention, showing the importance of reducing waste and using non-toxic materials. Key approaches include increasing process efficiency to minimize pollution at its source, adopting new business tools and materials, and fostering a cultural shift toward anticipating and internalizing environmental costs. This article demonstrates the significance of sustainable practices in managing soil, water, and air pollution, and calls for comprehensive programs to reduce, reuse, or prevent pollution.

5.3 Policies for better environmental protection and resource management

Effective policies and regulations are crucial for protecting water resources and managing environmental risks. Policymakers should focus on strengthening environmental protection laws, enhancing regulatory oversight, and promoting community engagement in water resource management. Collaborative efforts between government agencies, industry stakeholders, and local communities are essential for achieving sustainable water management outcomes. In alignment with Sustainable Development Goal 6 (SDG 6), which aims to ensure availability and sustainable management of water and sanitation for all, comprehensive frameworks such as the OECD (Organization for Economic Co-operation and Development) Council’s “Recommendation on Water” [26] provide valuable guidance. Key policies include managing water quantity through demand management and efficient allocation, improving water quality by setting standards and controlling pollution at the source, and addressing water risks and disasters via risk assessment and integrated emergency responses. The recommendation also emphasizes enhancing water governance by clarifying roles, ensuring policy coherence, and promoting stakeholder engagement. Sustainable financing and investment are supported through principles like Polluter Pays, diverse revenue streams, and appropriate water tariffs, aiming to balance economic, social, and environmental objectives. These guidelines aim to foster sustainable growth, social inclusion, and resilience against climate change, ultimately supporting the targets set by SDG 6.

Orr et al. [27] discusses the critical importance of effective policies and regulations in managing water scarcity and protecting water resources. They emphasize that water scarcity is primarily a governance issue rather than a mere physical shortage. Effective water management policies must address social, economic, and environmental factors, involving stakeholders at all levels—local, national, and international. The authors argue that robust regulatory frameworks are essential for sustainable water use, advocating for the enforcement of environmental laws, investment in water-efficient technologies, and the preservation of freshwater ecosystems. They stress that both governments and businesses must collaborate to mitigate water-related risks, ensuring long-term water security and environmental sustainability.

Reilly and Schindler [28] demonstrates the critical role of local governments in supplementing state and federal regulations to protect water resources. They stress that local governments can proactively address gaps through zoning and preventative measures, which are not always covered by state laws that often react to issues after they occur. Effective local policies include coordinated efforts to protect entire watersheds and integrate measures for groundwater, surface water, and wetlands, considering their interconnected nature. Examples of successful local initiatives include zoning ordinances that prevent groundwater contamination, wellhead protection programs, and shoreline management practices. This article argues that no single level of government can manage water resources alone, and a collaborative approach involving local, state, and federal levels, as well as community stakeholders, is essential for comprehensive water protection. Gerlak et al. [29] provides a comprehensive review of effective policies and regulations crucial for protecting water resources and managing environmental risks in the United States. They highlight the importance of adaptive management, which involves implementing policies on a trial basis, collecting data, and revising strategies based on the lessons learned. This approach encourages flexibility and responsiveness to new information and changing conditions. This document emphasizes the necessity of collaborative and integrated management of water resources, involving multiple agencies, stakeholders, and the public to achieve ecological and sustainable outcomes. Key policies such as the Clean Water Act (CWA), Safe Drinking Water Act (SDWA), and the Total Maximum Daily Load (TMDL) process are noted for their roles in setting national standards and promoting holistic environmental management. Overall, the integration of adaptive management principles, ecological restoration, and cross-agency collaboration are identified as critical elements for the future success of U.S. water policy.
