Morley","doi":"10.1002/awwa.2447","DOIUrl":"https://doi.org/10.1002/awwa.2447","url":null,"abstract":"<p>Myriad criminal and foreign actors are targeting water and other critical infrastructure systems. To date, acknowledged cyberattacks have not inspired action in the water sector as much as experts in national security and cybercrime believe is needed. Moreover, the risks that cybersecurity gaps pose to core water system functions do not appear to be adequately recognized.</p><p>The attacks on Sept. 11, 2001, led to a heavy emphasis on physical security solutions. While needed, this emphasis occurred to the detriment of needs related to cybersecurity and preparedness. The physical security improvements provided multiple benefits, but opportunities were missed to make similar investments for building resilience to sustain water systems’ continuity of service. The 2018 amendments to §1433 of the Safe Drinking Water Act (SDWA) intended to correct this imbalance by requiring systems to evaluate threats from both malevolent acts and natural hazards, recognizing that the latter have a significantly higher likelihood of occurring in any given day or year.</p><p>Today, there is nearly a 100% probability that every water system, regardless of type or size, is at risk of such attacks. Consequently, adequate prioritization of cybersecurity risk management is essential to utility leadership meeting their fiduciary duty to their ratepayers.</p><p>Beyond this obligation, there are legal “motivators” to act responsibly. SDWA §1433 obligates covered systems to consider cyberthreats to the full gamut of information and operational technology deployed. Section 1433 goes on to require covered systems to have “strategies and resources to improve the resilience of the system.” This statutory expectation applies to both physical security and cybersecurity.</p><p>AWWA's cybersecurity guidance and assessment tool have provided a structured approach tailored to identifying what cyber vulnerabilities have the highest priority based on how a system uses technology. Recent revisions provide an updated approach that begins with cybersecurity fundamentals—“the first mile”—that will provide the most immediate risk-reduction value to systems where those measures are not already implemented.</p><p>AWWA's <i>State of the Water Industry Report</i> demonstrates that awareness of cyberthreats is higher than it has ever been, rising in the past several years to consistently rank in the top 10 utility manager concerns. Progress indeed, but not enough to convince various federal decision makers that enough has been done. There are recurring calls for greater regulatory oversight and enforcement by the US Environmental Protection Agency (EPA) or states. AWWA and partners are supporting policy initiatives designed to provide a sound footing for sensible, risk-based cybersecurity measures in the sector that include additional funding, technical assistance, and enhanced information-sharing.</p><p>AWWA also supports H.R. 2594, the Water Risk and Resilience Organization (WRRO) Establishmen","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"117 5","pages":"8"},"PeriodicalIF":0.7,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2447","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anderson, Jessica L. Bennett, Chrissa Sfynia, Paul Bjorndahl, Peter Jarvis, Amina K. Stoddart, and Graham A. Gagnon&lt;/p&gt;&lt;p&gt;I am a PhD candidate at the Center for Water Resources at Dalhousie University (Halifax, N.S.); my research focuses on advanced oxidation processes in drinking water applications. Specifically, I’m investigating the formation of disinfection byproducts by UV-LED light and chlorine. Last year, I also started working as an instructor at Dalhousie, teaching first-year engineering courses. In this new role, I am trying to enhance the hands-on learning experience for undergraduate students and bring the sustainable awareness I’ve adopted from my research into the classroom. It has been incredibly fun applying my passion for learning, which prompted me to pursue a PhD in the first place, to this new position.&lt;/p&gt;&lt;p&gt;&lt;i&gt;At the Centre for Water Resources Studies, Isobel DeMont performs jar tests that were used to help local water utilities optimize their full-scale drinking water treatment operations&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;Consequences of climate change have led to significant changes in surface water quality around the world. One observed trend is the increased presence of climate-driven micropollutants, such as toxins produced by algae species that thrive in warm waters. Many of these micropollutants are resistant to conventional drinking water treatment processes. One potential technology that has proved to be effective is advanced oxidation with UV-LED light and chlorine. The blast of high energy from the UV-LED light breaks apart chlorine molecules, forming highly reactive compounds called radicals. The radical reactions change the molecular structure of the micropollutants, making them nontoxic. While this is a great outcome, the radicals also form byproducts when they react with other, nontoxic, organic compounds in the water, and some of the byproducts pose public health risks. My research investigates how we can tailor treatment conditions (e.g., chlorine dose, amount of light, UV-LED wavelength, water pH) to ensure the toxic micropollutants are degraded while minimizing the formation of harmful byproducts.&lt;/p&gt;&lt;p&gt;Radicals formed during advanced oxidation with UV-LED and chlorine react not only with climate-driven micropollutants but also with other nontoxic organic material in the water sample. The reactions between radicals and organic material often change the form of organic material but don’t degrade it entirely such that the total organic content concentration is reduced. As such, organic-content, concentration-based methods for evaluating treatment performance often are not suitable for evaluating advanced oxi","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"117 5","pages":"18-20"},"PeriodicalIF":0.7,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2449","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
