{"title":"Consumers Again Praise Utilities, But Work Remains","authors":"Adam T. Carpenter,&nbsp;Carita Parks","doi":"10.1002/awwa.2331","DOIUrl":"https://doi.org/10.1002/awwa.2331","url":null,"abstract":"&lt;p&gt;Since 2020, AWWA has commissioned an annual study of public confidence in drinking water. This study has provided valuable context and insight into how the public feels about water utilities.&lt;/p&gt;&lt;p&gt;The numbers could be even better. Evidence shows that proactive communication from utilities works. Those who recall receiving recent communication (other than a bill) from their utility gave higher ratings to their utilities and their water on many different metrics, and we’ve seen this for several years in a row.&lt;/p&gt;&lt;p&gt;It is likely proactive communication will better instill confidence than letting someone else take the narrative. Although we can only demonstrate correlation and not causation, there's reason to think that hearing information from a trusted source helps increase confidence.&lt;/p&gt;&lt;p&gt;Another area for improvement is closing the gap in ratings among Hispanic and Black respondents compared with White respondents, although Hispanic respondents’ ratings edged higher overall this year. This gap presents an opportunity to ensure all groups are receiving the same level of service as well as further targeted outreach and education.&lt;/p&gt;&lt;p&gt;Other SDWA-related questions were harder to interpret. When presented with the statement “The Safe Drinking Water Act has effectively regulated drinking water for the past 50 years,” while considerably more agreed (55%) than disagreed (14%), nearly a third (30%) did not know or had no opinion. Given the complexity of federal laws and regulations, these results are not so surprising and likely represent unfamiliarity with SDWA regulations. This suggests another topic utilities could further educate their consumers about.&lt;/p&gt;&lt;p&gt;Similar uncertainty was seen in responses to statements such as “Water utilities will show resilience in light of extreme events and climate change” and “Water utilities are prepared to face the challenges that they will see in the future.” This uncertainty represents key opportunities to talk about current activities and future plans with the public.&lt;/p&gt;&lt;p&gt;Utilities are encouraged to review all the detailed results and use them to gather insights on the national picture of public confidence and use that as context for inquiry and engagement in their own communities. We encourage readers to view the press release, infographic, and AWWA's Value of Water page.&lt;/p&gt;&lt;p&gt;Throughout the year, we receive questions on how the survey was conducted. We hired a top polling firm, Morning Consult (MC), who walks us through the whole process for each study, making sure we ask questions free from avoidable bias, and seeks to provide meaningful insights. The survey is nationally representative per MC's methodology used in hundreds of other surveys. The more than 2,000 respondents did not know the survey's sponsor and had self-reported, before taking the survey, that they were served by a water utility.&lt;/p&gt;&lt;p&gt;This survey also has some limits, of course. It is nationally representative by key demographics, bu","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"116 8","pages":"8"},"PeriodicalIF":0.7,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2331","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142234902","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}

{"title":"AWWA Water Science Author Spotlight: Jonathan B. Burkhardt","authors":"","doi":"10.1002/awwa.2334","DOIUrl":"https://doi.org/10.1002/awwa.2334","url":null,"abstract":"&lt;p&gt;&lt;b&gt;Having recently published an article in &lt;i&gt;AWWA Water Science,&lt;/i&gt; Jonathan B. Burkhardt answered questions from the publication's editor-in-chief, Kenneth L. Mercer, about the research.&lt;/b&gt;&lt;/p&gt;&lt;p&gt;&lt;b&gt;Pressure-Dependent Analysis in Premise Plumbing System Modeling&lt;/b&gt;&lt;/p&gt;&lt;p&gt;Jonathan B. Burkhardt, John Minor, Feng Shang, and William E. Platten III&lt;/p&gt;&lt;p&gt;&lt;i&gt;Jonathan Burkhardt is an environmental engineer in the US Environmental Protection Agency's Office of Research and Development&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;I earned PhD, MS, and BS degrees in chemical engineering from the University of Cincinnati. My undergraduate education included a cooperative learning experience, where I worked in a chemical manufacturing facility. Following graduate school, I participated in an ORISE (Oak Ridge Institute for Science and Education) post-doctoral fellowship with the EPA, conducting research into event detection software and multispecies water quality modeling. I also routinely participate in AWWA and ASCE (American Society of Civil Engineers) conferences to keep up to date with current research.&lt;/p&gt;&lt;p&gt;For models to be effective, they typically require a theoretical foundation (or the mathematical formulas on which they are built) and usually require information about the parameters that make those formulas relevant for appropriate conditions or scenarios. Much of my work focuses on developing appropriate parameters that make the models work.&lt;/p&gt;&lt;p&gt;I am also trying to understand whether the parameters or models are valid for what we are studying. For our recent paper, we focused on trying to determine parameters for predicting how the pressure at faucets affected the rate at which water was supplied by those faucets. This information is important because it helps us improve those predictions in the EPANET (a public domain software application for modeling water distribution systems) network modeling and more accurately predict flow rates as pressures change in those premise plumbing (home and building) systems.&lt;/p&gt;&lt;p&gt;&lt;i&gt;Jon enjoys a hike through Turkey Run State Park in Indiana&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;We did not really use any new techniques in this work but rather relied on available pressure and flow sensors attached to a data logger to help capture the data we reported. The results of this work do provide valuable information to the larger research project about premise plumbing modeling and are being incorporated in our model development.&lt;/p&gt;&lt;p&gt;As research goes, this research went fairly smoothly. Using automated data collection required a little work up front to make sure we could read that data into our scripts correctly, but this was generally an easy and expected step. The differences in pressure/flow relationships for various fixtures was an expected outcome. The only real challenge was isolating cold- or hot-only sides of the shower mixing valve; luckily, this was easily overcome with adjustment screws that are present on the mixing valve.&lt;/p&gt;&lt;p&gt;This work was part of a larger","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"116 8","pages":"24-26"},"PeriodicalIF":0.7,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2334","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142234807","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}

{"title":"The Shape of AWWA","authors":"David B. LaFrance","doi":"10.1002/awwa.2345","DOIUrl":"https://doi.org/10.1002/awwa.2345","url":null,"abstract":"&lt;p&gt;It took less than a minute on Oct. 26, 1881. In that moment, Wyatt Earp, Doc Holliday, and the Clanton Gang engaged in the historic gunfight at the O.K. Corral. Since then, numerous movies have been produced and books published about this fateful incident in Tombstone, Ariz.&lt;/p&gt;&lt;p&gt;While much less documented, another significant, life-changing event occurred seven months earlier. It took days, not seconds, 1,400 miles away from Tombstone. The spot was Engineers’ Hall at Washington University in St. Louis, Mo. Twenty-two water utility employees from Illinois, Indiana, Iowa, Kansas, Kentucky, and Tennessee gathered for the first time to share best practices in water treatment, leading to the creation of the American Water Works Association. Together, they drafted and adopted AWWA's original constitution, stating the organization's purpose was “to exchange information about water-works management and to advance both consumers and water companies, and for the purpose of securing the economy and uniformity in the operations of water-works.”&lt;/p&gt;&lt;p&gt;During the 143 years of AWWA's history, its members have grown from the original 22 to more than 50,000. Also, AWWA is now known as the leading standards-writing organization for the water sector. The first AWWA standard was published in 1908 on the &lt;i&gt;Specifications for Cast Iron Water Pipes and Special Castings&lt;/i&gt;. Today, AWWA offers water professionals more than 190 ANSI (American National Standards Institute)-approved standards.&lt;/p&gt;&lt;p&gt;As AWWA's membership grew, it recognized the benefit of disseminating knowledge that originated from the association as well as from local cohort groups. This strategic realization brought AWWA to create its first local section, the New York Section, in 1914. Two years later, there were eight AWWA sections, including one in Canada (which encompassed the entire country). By 1930, AWWA needed a headquarters office, which it established in New York City, along with a newly hired staff. AWWA now has 43 sections that span geographically from Maine in the eastern United States to Alaska on the western edge, and from Canada to the north to Mexico to the south. Add to that an association staff of 150, located in Denver and Washington, D.C.&lt;/p&gt;&lt;p&gt;During the second half of the 1900s, AWWA focused on the critical need for research about water treatment and management. Its board of directors formed a water research foundation in 1966. Today, The Water Research Foundation is a One Water organization, delivering research programming to help address the water sector's current water challenges. Similarly, in 1991, AWWA leaders heeded a calling to help improve water systems around the world. These leaders envisioned, and AWWA created, Water For People, which is now a highly regarded global nonprofit that addresses the global water crisis in nine countries in Latin America, Asia, and Africa.&lt;/p&gt;&lt;p&gt;Along the lines of looking forward and spreading water knowledge beyond the boundaries of Nor","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"116 8","pages":"108"},"PeriodicalIF":0.7,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2345","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142234811","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}
