An environmental campaign group says chemical makers are ramping up output of PFAS, the persistent "forever chemicals", to meet demand tied to AI data centres. The warning comes amid growing regulatory scrutiny of the substances over health and environmental concerns. Manufacturers have not commented on the claim.
Former Environmental Protection Agency officials say the Trump administration is relaxing pollution rules to accelerate construction of AI data centers. In a new report and briefing, they argue the rollback puts Americans' health at risk and are pressing the president to reverse course. The group's appeal is seen as unlikely to change the administration's approach.
A revised arXiv preprint proposes a method for learning intrinsic water-quality dynamics that incorporates rainfall as an environmental driver. Rainfall affects water quality through runoff, pollutant transport, dilution and resuspension, processes that mechanistic models describe explicitly but which are hard to capture in purely data-driven approaches. The work aims to combine these perspectives for improved forecasting.
