Navigating the Shifting Tides of US Water Policy: Regulatory Developments, Infrastructure Challenges, and Climate Impacts

  • Resumen

  • Across the United States, water policy and management have seen significant developments this past week. The Environmental Protection Agency and the Army Corps of Engineers began a series of nationwide listening sessions aimed at clarifying which water bodies receive federal protection under the Clean Water Act. This initiative seeks to align federal definitions with the U.S. Supreme Court’s 2023 Sackett decision, potentially narrowing the scope of protected waters and prompting input from stakeholders concerned about future regulation and conservation. At the federal level, Congress returned from recess to focus on major water-related issues. The House Energy and Commerce subcommittee held discussions on a package of energy bills that impact water use, including hydropower and transmission infrastructure. Simultaneously, the Senate Committee on Environment and Public Works addressed the critical topic of federal water infrastructure funding, with testimony from both state and local officials. These hearings underscore ongoing concerns about sustaining drinking water systems, upgrading aging infrastructure, and supporting rural and urban communities facing water challenges, as reported by Circle of Blue.

    One focal area is the Lower Missouri River, where the Army Corps of Engineers announced a comprehensive flood risk review covering 735 miles from Sioux City, Iowa, to St. Louis. This region has suffered three so-called 500-year floods in the past three decades, prompting collaboration among Iowa, Kansas, Missouri, and Nebraska to better understand and reduce risk in the face of increasingly frequent extreme weather.

    On the regulatory front, the Environmental Protection Agency’s new rule to limit per- and polyfluoroalkyl substances, called PFAS, in drinking water remains under legal scrutiny. Major trade associations and water utilities have filed suit, challenging both the rapid rulemaking process and its compliance costs. The EPA, under new leadership, requested and received a 30-day extension in court to further review the contested rule and consider potential changes. According to WaterWorld and other sources, this litigation highlights deep divisions regarding how quickly and stringently PFAS contamination should be addressed nationwide and what role states versus federal authorities should play.

    Meanwhile, localities like New Jersey are grappling with their own mix of climate-driven water supply challenges, including drought, infrastructure breakdowns, algal blooms, and persistent PFAS pollution. A draft statewide water supply plan emphasizes the need for stronger planning, resilient infrastructure, and rapid response to emerging contaminants, warning that climate variability and aging systems compound risks to both quantity and quality of water supplies.

    Internationally, the month saw major open water swimming competitions in the United States including the U.S. Open Water Nationals, marking the start of a busy season for aquatic sports and the spotlight on water quality in host regions. These diverse developments reflect a pattern of increasing regulatory attention, legal contestation, and climate-driven pressures in American water policy, with ripple effects for ecological protection, public health, and community resilience.
