As project manager, I coordinate our team's project-wide planning and logistics, and I maintain our partnerships with over 40 small to large public and tribal utilities across the country.&lt;/p&gt;&lt;p&gt;&lt;i&gt;Matt Vedrin kneels next to a hydrant in Ann Arbor, Mich., where he conducted research on monitoring and management of drinking water quality through hydrant-flushing programs&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;I stumbled upon engineering during my undergraduate studies; I didn’t have much exposure to engineers growing up and didn’t know it would interest me. I was drawn to the structured problem-solving approach that required critical and creative thinking. I decided to pursue mechanical engineering for my undergraduate degree but took five years to finish because I participated in two semester-long exchange programs, one in Sweden and another in Brazil.&lt;/p&gt;&lt;p&gt;&lt;i&gt;Matt enjoys a piece of pizza made for a pizza party to raise money to fight local food insecurity&lt;/i&gt;.&lt;/p&gt;&lt;p&gt;Our tap water originates from some kind of natural water source like a river or aquifer. That water is treated through a series of treatment steps that target the removal of contaminants like harmful microbes and chemicals, both from the environment and from agriculture or industry, that end up in natural water sources. The treated water is then sent through a network of underground pipes and finally connects with the plumbing in our homes.&lt;/p&gt;&lt;p&gt;I study how water quality changes from the moment it leaves the treatment plant to when it reaches your faucet and how to make sure it remains safe to consume. One of the ways that utilities help maintain good water quality as it travels to your tap is by occasionally flushing water out of the system. Although it might seem wasteful, it is one of the only ways to have an impact on the water and pipes underground without digging them up and risking contamination from the outside environment. Utilities work hard to ensure people have access to safe water 24-7, and my role as a researcher is to study treatments, contaminants, and management strategies that help utilities keep water safe well into the future.&lt;/p&gt;&lt;p&gt;What I love about the work from my &lt;i&gt;AWWA Water Science&lt;/i&gt; article is that it is a great example of the mutual respect that u","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"117 7","pages":"21-24"},"PeriodicalIF":0.4,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://awwa.onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2482","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144833140","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":"Infrastructure and Affordability","authors":"Adam T. Carpenter","doi":"10.1002/awwa.2480","DOIUrl":"10.1002/awwa.2480","url":null,"abstract":"&lt;p&gt;Building on themes from my July/August 2024 column, “Affordability: Two Sides of the Same Coin,” how big is America's water infrastructure funding need, and how big of a challenge is affordability? It ends up that it depends on whom you ask and what specifically you are asking. There is a massive need for investment in water infrastructure, while simultaneously affordability is a substantial and growing concern. Over time, most of the costs of infrastructure ultimately have been paid for locally. The bulk of federal and state infrastructure funding occurs through mechanisms such as the Drinking Water and Clean Water State Revolving Loan Funds (SRFs), Rural Development (Water &amp; Environment Programs) loans, and the Water Infrastructure Finance and Innovation Act. While loan rates are subsidized by these programs compared with market rates, only disadvantaged communities as defined by state programs have access to loan forgiveness for a portion of SRF loan amounts.&lt;/p&gt;&lt;p&gt;While increased funding for the SRFs from the Infrastructure Investment and Jobs Act (IIJA) will continue through fiscal year 2026, discussions about possible extensions are in early stages and not guaranteed. As of this writing, annual SRF appropriations (outside of IIJA) are not yet known but may be reduced from prior levels. So what is the scope of US water infrastructure needs?&lt;/p&gt;&lt;p&gt;&lt;b&gt;AWWA's flagship&lt;/b&gt; &lt;b&gt;&lt;i&gt;Buried No Longer&lt;/i&gt; report (2012)&lt;/b&gt; used historical water main sales data and anticipated replacement rates to estimate a &lt;i&gt;$1 trillion need over 25 years&lt;/i&gt; for replacement and expansion of buried drinking water infrastructure. Although a pivotal assessment, it does not cover more recently identified challenges, and we are now halfway through the time period it covered.&lt;/p&gt;&lt;p&gt;&lt;b&gt;The US Environmental Protection Agency's (EPA's)&lt;/b&gt; &lt;b&gt;seventh drinking water needs survey (2023)&lt;/b&gt; found &lt;i&gt;$625 billion in need over 20 years&lt;/i&gt; for SRF-eligible projects across US states, territories, and Washington, D.C. Notably, this estimate was prepared before several major regulatory actions.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Major new drinking water regulations&lt;/b&gt; are generating new costs. Estimates from an AWWA-sponsored study include the cost for drinking water treatment to comply with the per- and polyfluoroalkyl substances (PFAS) drinking water standards at &lt;i&gt;$37.1–$48.3 billion in capital improvements&lt;/i&gt; alone. The costs of full lead service line replacement as required by the Lead and Copper Rule Improvements (LCRI) cost an average of $12,500 each, meaning the cost of removing the more than nine million estimated remaining US lead service lines would &lt;i&gt;exceed $100 billion&lt;/i&gt;—a task that the LCRI requires water systems to complete by 2037.&lt;/p&gt;&lt;p&gt;&lt;b&gt;EPA's&lt;/b&gt; &lt;b&gt;affordability needs assessment&lt;/b&gt; found that 12.1 to 19.2 million households may already have water bills that exceed affordability thresholds by &lt;i&gt;$5.1–$8.8 billion per year&lt;/i&gt; cumulatively, demonstrating a substantial affor","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"117 7","pages":""},"PeriodicalIF":0.4,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://awwa.onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2480","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144833131","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}
