Giammar&lt;/p&gt;&lt;p&gt;&lt;i&gt;Anushka Mishrra at work in the laboratory at the University of California, Berkeley&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;I earned an undergraduate degree in chemical engineering. I then pursued a PhD in energy, environmental, and chemical engineering, where my research focused on legacy contaminants in drinking water supply and distribution systems. Currently, in my postdoctoral work, I am developing water treatment technologies to remove toxic hexavalent chromium from drinking water sources, which allows me to apply my expertise toward improving water quality and environmental health.&lt;/p&gt;&lt;p&gt;&lt;i&gt;Pausing during a hike up Mount Diablo in Northern California&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;During my PhD work, I studied the effect of sodium silicate, a type of corrosion inhibitor, on lead release from lead service lines and observed that it can significantly reduce lead to very low concentrations. In our &lt;i&gt;AWWA Water Science&lt;/i&gt; article, we investigated the mechanism behind this corrosion control path using sodium silicate. Specifically, we aimed to understand whether sodium silicate chemically reacted with lead-based solids formed in the pipe or if it created a physical barrier to prevent lead from releasing into the water.&lt;/p&gt;&lt;p&gt;To understand the interactions between silica, lead-based corrosion products, we used a unique approach: Rather than simply collecting water samples from lead pipes, we removed solids from the interior of actual lead pipes and suspended them in water for our experiments. This method allowed us to study lead release under controlled conditions, offering a fresh perspective beyond typical field or laboratory setups. We applied surface characterization techniques to examine the interactions and structural changes on the pipe material, gaining insights into how the corrosion inhibitor affects lead release.&lt;/p&gt;&lt;p&gt;I was initially apprehensive about investigating the mechanism by suspending real lead pipe scales or corrosion products, aiming to eliminate the diffusion-limited transport typically present within the pipe. To my surprise, we did not observe any specific chemical interactions between silica and lead that would indicate a decrease in lead solubility. This unexpected result revealed that silica's role in corrosion control is achieved primarily by inhibiting the diffusion of lead from the corrosion products in the lead service lines.&lt;/p&gt;&lt;p&gt;Our research has highlighted silica's role in reducing lead release, along with insights into its inhibition mechanism. This opens up opportunities to investigate whether this phenomenon is specific to lead service lines with a thick layer of corrosion products inside the pipe. Additionally, it would be v","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"117 1","pages":"21-22"},"PeriodicalIF":0.7,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2383","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118339","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}

AWWA's members are engineers, scientists, operators, utility managers, educators, public officials, and more. Each of you has unique knowledge and experience that can help provide critical perspective to members of Congress.&lt;/p&gt;&lt;p&gt;In AWWA's Government Affairs office, one of our primary roles is helping to effectively facilitate knowledge transfer between our members and Congress to achieve positive policy outcomes. There are 435 voting members of the House of Representatives, 100 members of the Senate, and committees in both chambers with direct jurisdiction over the various aspects of water policy. Though they consider legislation and hold hearings on water sector priorities, members of Congress typically don’t have experience in the water sector. A recent report from the Congressional Research Service noted that fewer than 10 members of Congress were engineers and as few as five were scientists. Your expertise, as water professionals and constituents, can be helpful in communicating your own utility's needs in a way that resonates with your representative.&lt;/p&gt;&lt;p&gt;However, we know that educating Congress is not part of your job description. We work hard to keep you updated on federal legislative activity, provide advocacy tools and resources, and streamline the process of reaching out so that you can build a relationship between your utility and your representative's office. The simple act of sending a letter or making a phone call can help raise awareness of an issue for your representative. Inviting your representative to tour your utility is also a great way to convey the importance and complexity of the service you provide. Ultimately, by taking the time to connect with your representative, you can establish yourself and your utility as a trusted resource on Capitol Hill.&lt;/p&gt;&lt;p&gt;At our signature event, the annual Water Matters! Fly-In, more than 150 AWWA members from around the United States meet with their representatives on Capitol Hill to discuss federal legislation and the water sector's needs. We work alongside AWWA's Water Utility Council to outline policy priorities that inform our Fly-In advocacy, and we provide information and materials to help you make the most of your conversations. These meetings give our members the opportunity to educate lawmakers and their staffs, demonstrate local connections to federal policymaking, and elevate the importance of water on Congress's agenda.&lt;/p&gt;&lt;p&gt;These interactions help build trust and set the foundation for additional outreach in the future. By meeting with your lawmaker as a representative of AWWA, you reinforce AWWA's reputation as a leader in drinking water policy. These meetings can also act as a primer for AWWA's legislative affairs staff, who can follow up","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"116 10","pages":"5"},"PeriodicalIF":0.7,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2364","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665052","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}

Especially now, with upcoming deadlines and regulations for Lead and Copper Rule Revisions and Lead and Copper Rule Improvements, much of my work has to do with helping communities survey their service line materials, which means I spend a lot of time looking at historical records or going into the field and observing excavations.&lt;/p&gt;&lt;p&gt;&lt;i&gt;Liam Amery does a walkthrough at a school to design a sampling plan to test its drinking water for lead&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;&lt;i&gt;Liam presents research on lead in schools at the 2023 Water and Health Conference at the University of North Carolina&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;Lead in drinking water has been an issue for a long time; I remember the Flint water crisis being a big deal back when I was in high school and was not yet remotely interested in the world of water science and environmental engineering. Luckily, in the aftermath of Flint, the Massachusetts Department of Environmental Protection and UMASS Amherst have been collaborating on a joint program to help schools and childcare centers test their drinking water for lead (and previously copper). Because they make these data available, results from more than 1,000 schools and childcare centers statewide are accessible online. This program and the data that were gathered from it motivated this work and inspired us to think about how we can use these data to understand factors influencing lead in drinking water in these facilities.&lt;/p&gt;&lt;p&gt;None in particular, but many studies nationwide are focusing on lead in schools and childcare facilities, using data from sampling programs to achieve their study goals. A few other studies have used data from the same portal we used, and I reviewed them closely during the initial stages and planning of our study: Lobo et al. 2022 (https://doi.org/10.1016/j.scitotenv.2021.150046), Ram 2019 (https://scholarworks.umass.edu/cee_ewre/99), and Rome et al. 2022 (https://doi.org/10.1021/acs.estlett.1c00845).&lt;/p&gt;&lt;p&gt;Most of our data analysis and modeling are methods that have been used previously. One of the newer methods in our study was to create risk indexes for a school based on percentages of taps exceeding different water lead level (WLL) thresholds. One of the more difficult issues with studying lead in drinking water is how much variability can exist within different taps at the same school as well as the different WLL thresholds that are used and are either health based or policy based.&lt;/p&gt;&lt;p&gt;&lt;i&gt;Liam surveys a beaded stream in Alaska as part of a research experience during his undergradua","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"116 10","pages":"16-18"},"PeriodicalIF":0.7,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2367","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142664742","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}
