Fourteen illegal chrome miners were found dead and at least eight injured after a cave-in near an abandoned shaft by the Nkaneng informal settlement, close to Marikana in South Africa’s North West province, with the collapse estimated around 21:00 on Monday. Police have intensified action against illegal chrome operations in the province, seizing 20 trucks and 15 excavators over the past two years and arresting survivors on suspicion of illegal mining. The incident underlines ongoing geotechnical and safety risks where informal miners re-enter abandoned gold, platinum and chrome workings without ground support or regulated access control.

A worker at the Sellafield nuclear decommissioning site “died suddenly” during the week commencing 6 July, prompting an immediate review by the Office for Nuclear Regulation (ONR). ONR has confirmed the death was not work-related and that there was no radiological or conventional safety incident affecting the wider site. Routine regulatory oversight of Sellafield’s legacy waste facilities, spent fuel management and construction activities continues unchanged, with no impact reported on nuclear safety cases or site operations.

The British Geological Survey has launched a four‑year ground investigation of the River Tweed catchment to characterise groundwater behaviour and its interaction with river levels for improved flood forecasting. Work will include installing new monitoring boreholes, logging groundwater heads and flow paths, and integrating hydrogeological data with existing river‑gauge and rainfall records across the cross‑border catchment. Findings are expected to refine flood models used by local authorities and infrastructure owners, particularly for groundwater‑dominated flood events and prolonged saturation of transport and drainage assets.
