A two-day hackathon event took place last week seeking solutions to the high pollution levels of the Afon Teifi.

Last year Dŵr Cymru/ Welsh Water admitted to illegally spilling millions of litres of raw sewage into rivers in Wales, with the river Teifi, spanning across Ceredigion and Carmarthenshire, being one of the worst hit.

Community groups, charities, and expert organisations came together to tackle issues contributing to the pollution including land use and agriculture adding to pollution levels through land runoff, as well as how enforcement and regulation can be improved.

The event also explored citizen science initiatives, a long-called-for idea from the resident-led grassroots group Save the Teifi to boost community collaboration and support water quality monitoring.
