🚰🥬 Did you know that sediment in irrigation water can increase E. coli contamination, putting fresh produce—and human health—at risk? A study by Jennifer Guohong Duan, Erfan Tousi, Patricia M. Gundy, Kelly Bright, and Charles P. Gerba uses machine learning to unveil this hidden threat. Explore their dataset and article at doi.org/10.25422/azu.data.2109 and doi.org/10.1016/j.scitotenv.20.

Way to go, SF.gov. 🙄

When Sam Alito is on your side, you know you're doing something wrong.

The EPA issued San Francisco a permit allowing it to discharge pollutants from its combined sewer system into the Pacific Ocean. The permit’s conditions include prohibitions on discharges that contribute to a violation of applicable water quality standards. The permit included generic prohibitions on the impacts to water quality, as part of the EPA’s efforts to halt San Francisco’s releases of raw sewage into the Pacific Ocean during rainstorms.

San Francisco challenged these conditions, arguing that EPA lacks statutory authority to impose them. The US Court of Appeals for the ninth circuit in July 2023 upheld EPA’s authority to issue generic limits on discharges under the Clean Water Act. San Francisco took the case to the supreme court.

Sewage scandal: The dirty secret polluting England and Wales.

Since Brexit, the UK is no longer subject to EU water quality standards. In England and Wales, floods of untreated wastewater have been discharged into rivers and seas, harming the health of residents and destroying ecosystems. FRANCE 24's Down to Earth team reports.

#PétrusseValley to undergo second phase of #rewilding

The Pétrusse rewilding project and redesign of the adjoining park aim to be finished for the 2027 school year

10/02/2025

"The second phase of the rewilding of the Pétrusse valley, extending from the #BourbonLock to #RuedAnvers in #Luxembourg City, is set to begin in spring.

"The valley has already been #rewilded along a section extending from Rue St. Ulric to the Bourbon lock during the first phase of the larger project, which began in 2020.

"The City of Luxembourg, in collaboration with the Ministry of the #Environment, #Climate, and #Biodiversity, held a press conference on Monday outlining the details of the second phase, which includes the installation of stands and balconies along the route and a new multi-purpose sports field.

"'The rewilding of the Pétrusse valley represents an exceptional project for the City of Luxembourg, aiming to enrich our environment while improving the quality of the citizens’ lives,' Mayor Lydie Polfer said.

"The rewilding initiative came just days after a European Commission report on water quality showed rapidly declining results in Luxembourg.

"The first report, in 2009, indicated that 7% of the country’s surface waters were in good ecological condition, before falling to 3% in 2015 and finally reaching 0% in 2021. The ecological status is influenced by water quality such as #pollution and #habitat #degradation. It is used to define the overall status of water bodies.

"The #EuropeanUnion wants all surface waters to be in good condition by 2027. Under the #EuropeanWaterFrameworkDirective (#WFD) – which sets markers for water quality, the country has to see its standards improve.

"'#Restorations are perfect measures to adapt to the increasing challenges of #ClimateChange while contributing to the improvement of #biodiversity, #WaterQuality and increasing the quality of life of our citizens,' Environment Minister Serges Wilmes said."
