A satellite analysis shows the Lincoln Memorial Reflecting Pool had its largest June algae bloom in at least five years, occurring days after a $14 million renovation, with EarthCam photos showing widespread growth and weather conditions likely contributing to the spike.
EWG’s 2021–2023 analysis of nearly 50,000 public water systems finds about 62 million Americans (roughly 1 in 5) may drink tap water with nitrate levels linked to health risks; millions exceed 3 mg/L and thousands exceed 5 mg/L, with some wells reaching much higher levels. Nitrates largely come from agricultural fertilizers and manure, and private wells aren’t covered by EPA rules. Mitigation includes home reverse-osmosis filters, but tighter regulations and consumer awareness are urged, as bottled water is not a guaranteed fix.
A persistent, mysterious algal bloom off South Australia’s coast has killed marine life and fouled beaches for over a year, upsetting communities and raising concerns about the health of the ocean.
A large US study linked Parkinson’s disease risk to where and how people get their drinking water. People drinking from carbonate aquifers had a 24% higher PD risk than those using other aquifers and a 62% higher risk than those drinking from glacial aquifers. Newer groundwater (past 75 years) in carbonate systems was tied to about 11% higher risk than older water. The study analyzed 12,370 people with PD and over 1.2 million without, all within 3 miles of groundwater sampling across 21 major US aquifers, and noted limitations like assuming uniform aquifer characteristics within radius. Carbonate aquifers are common in the Midwest, South, and Florida, while glacial aquifers are more in the Upper Midwest and Northeast. The findings suggest groundwater age and source may influence long-term neurological health, warranting further research.
DC Mayor Muriel Bowser declared the Potomac River sewage spill a public emergency and sought federal help to cover cleanup costs, as temporary pipes divert sewage into the C&O Canal to allow repair of the six‑foot Potomac Interceptor after January’s collapse.
President Donald Trump said the federal government will help respond to a major raw-sewage spill into the Potomac River, directing federal agencies to coordinate the cleanup after about 200 million gallons spilled, with barriers redirecting sewage and FEMA/EPA involvement.
A large sewer pipe collapse near I-495 and Clara Barton Parkway caused hundreds of millions of gallons of raw sewage to spill into the Potomac, leaving sewage remnants on land and in the water. DC Water says repairs will take about nine months, using bypasses to the C&O Canal and Potomac Interceptor, while state and local officials monitor water quality and public health risks across the District, Maryland, and Virginia.
A 12-year-old boy, Nico Antic, died from injuries after a shark bit him in Sydney Harbour last week as he and friends jumped into the water from a rock in Vaucluse. Heavy rains made the harbor water murky, which officials say is linked to increased shark activity. The incident follows several other shark encounters in the area, prompting beach closures and warnings to avoid swimming in harbor waters amid concerns over rising shark activity and changing migratory patterns.
The Transportation and Infrastructure Committee approved multiple bills, including the Aviation Funding Solvency Act to protect the air traffic control system during government shutdowns, and legislation to modernize aviation, improve water quality, and relocate the FBI headquarters, among other initiatives.
The Chicago River hosted its first organized open swim in nearly 100 years, celebrating its environmental recovery thanks to improved water quality and conservation efforts, with 263 swimmers participating and the event raising funds for ALS research.
Over 250 swimmers participated in the first open-river swim in nearly a century in Chicago, marking a milestone in the river's recovery from pollution, supported by water quality testing showing safe conditions and investments in environmental cleanup, symbolizing Chicago's commitment to making its waterways swimmable and recreational again.
A small dam in upstate New York was removed, leading to rapid ecological recovery within three years, including improved water quality, increased habitat diversity, and the return of fish and macroinvertebrates, demonstrating nature's resilience and the benefits of removing obsolete barriers to restore river health.
The Oklahoma City-County Health Department is investigating water quality concerns at OKANA Resort's waterpark after a failed inspection revealed zero chlorine levels, which was temporarily corrected. The resort emphasizes its commitment to safety, with frequent water testing and adherence to safety standards, while authorities assess the situation to ensure public health.
US beaches are under fecal contamination warnings ahead of Labor Day weekend due to high bacteria levels from pollution sources like runoff and sewer overflows, posing health risks to swimmers and prompting advisories and closures at popular destinations.
Many US beaches are under advisories due to unsafe levels of fecal contamination, caused by outdated sewage systems and severe weather, posing health risks to swimmers during the Labor Day weekend.
