Urgent: Nationwide Drinking Water Alert! Cybersecurity Threats Emerge

03 May, 2025

Are you drinking safe water? A nationwide drinking water warning issued by the Environmental Protection Agency (EPA) signals a critical moment for the United States, with potential implications for the health and safety of millions.

Published on May 20, 2024, at 4:48 PM EDT, and updated on May 24, 2024, at 10:49 AM EDT, this alert underscores the urgent need for action. The EPA's warnings are particularly focused on cybersecurity threats and vulnerabilities plaguing community drinking water systems, a situation that demands immediate attention.

Gabe Whisnant, a breaking news editor at Newsweek, based in North Carolina, has been following this developing story, providing crucial updates on the evolving situation. The EPA's enforcement alert outlines the steps community water systems must take to comply with the Safe Drinking Water Act, highlighting the seriousness of the potential risks. The agency's actions underscore a growing concern about the vulnerability of water infrastructure to cyberattacks.

The EPA's action is a direct response to the escalating frequency and severity of cyberattacks targeting water and wastewater systems. The agency's enforcement alert serves as a crucial reminder of the essential role cybersecurity plays in safeguarding the nation's water supply. This initiative follows an alarming report revealing that 70% of the nation's water systems inspected fail to meet the Safe Drinking Water Act's standards, primarily due to outdated cybersecurity practices. The consequences of these vulnerabilities can range from minor disruptions to widespread contamination, underscoring the urgency of the EPA's warning.

The Kansas Department of Health and Environment's issuance of a boil water advisory for the Cloud County Rural Water District 1 on Wednesday, following a waterline break that led to a loss in pressure, is a stark reminder of the fragility of water systems. This incident, while not directly related to cyberattacks, underscores the importance of maintaining the integrity of water infrastructure. The EPA's actions emphasize that vigilance is needed on multiple fronts.

The EPA's enforcement alert, issued the previous day, emphasizes the need for swift action to mitigate threats to the nation's drinking water. The agency plans to increase inspections to ensure compliance and is prepared to take further action if needed. The agency is determined to safeguard the safety and health of water in the US.

The Environmental Protection Agency (EPA) has issued a countrywide alert, urging immediate action from water utilities across the United States to protect drinking water from cyberattacks. The organization is requesting utility systems to take immediate action to protect the country's drinking water from cyberattacks. The EPA emphasizes the critical importance of proactive measures.

In June, the EPA also issued final advisories for limits in drinking water of GenX (a replacement for PFOA) and PFBs (a replacement for PFOS), setting limits of "less than 10 ppt and 2,000." This is also a step to protect the safety of water supplies in the country.

The EPA's announcement of an unprecedented drinking water warning nationwide reveals alarming vulnerabilities in America's water infrastructure. This critical alert follows the discovery of widespread cybersecurity gaps, potentially affecting millions of households across the United States. These gaps, often stemming from outdated technology and poor cybersecurity awareness, could compromise essential water supplies.

The EPA's Monday enforcement alert calls on water utility systems to take immediate actions to protect the nation's drinking water from cyberattacks. The agency has found that such attacks are becoming more severe and frequent, which can put drinking water at risk for Americans all over the country. Federal officials have found that some 70% of water systems nationwide have shortcomings that make them vulnerable to cyberattacks, some as simple as unchanged default passwords on computer control systems.

This funding complements $3.4 billion in funding going through the Drinking Water State Revolving Funds (SRFs) and $3.2 billion through the Clean Water SRFs, which can also be used to address PFAS (per- and polyfluoroalkyl substances) in water this year. Lifetime drinking water health advisories for four PFAS are being released by the agency in light of newly available information.

The White House has expressed concern that cyberattacks are hitting water and wastewater systems "throughout the United States," and state governments and water facilities must improve their defenses against the threat. The Safe Drinking Water Act (SDWA) authorizes the U.S. Environmental Protection Agency to issue health advisories for contaminants that are not subject to a national primary drinking water regulation (NPDWR) (42 U.S.C.). HA documents provide technical information on chemical and microbial contaminants that can cause human health effects.

New data reveals that 8,865 sites across 50 states, the District of Columbia, and four territories have PFAS contamination. The EPA has released the sixth round of public water system quarterly testing data for PFAS, as required by its fifth unregulated contaminant monitoring.

On May 20, 2024, the EPA warned that cyberattacks against water utilities across the country are becoming more frequent and more severe, as it issued an enforcement alert urging water systems to take immediate actions to protect the water supply. The agency is urging immediate upgrades to cybersecurity measures for water utilities after revealing significant vulnerabilities that could jeopardize the nation's drinking water supply.

The Biden administration is calling on states to bolster security for water and wastewater systems, warning that utilities nationwide are being targeted by "disabling cyberattacks." These measures are intended to ensure America's water infrastructure is secure.

Key areas being addressed include cybersecurity assessments for drinking water and wastewater systems, as well as the implementation of risk and resilience assessments and emergency response plans, as outlined in America's Water Infrastructure Act section 2013. The enforcement alert addresses select provisions of the Safe Drinking Water Act using plain language.

The situation highlights the necessity of proactive measures to protect the nation's water supply. The EPA's actions are a critical step in safeguarding public health and ensuring the resilience of critical infrastructure.
