The iconic Dyfi River and its tributaries, is under threat due to the contamination of freshwater with rock salt. Thanks to the local community we have traced the source of this contamination back to an uncovered pile of rock salt in Llanbrynymair, which has been leaching into the environment during rainfall through surface run off.

The excessive surface runoff carrying the dissolved rock salt is exacerbating an already critical issue. Llanbrynmair, experienced the highest recorded CSO release levels in 2022, endangering the river and its delicate ecosystem. This alarming evidence confirms that both sewage discharge and high surface runoff are directly harming river health.

Furthermore, the consequences of this contamination extend beyond water quality. The corrosive nature of rock salt poses a threat to infrastructure, further endangering the safety and stability of vital structures. Additionally, the freshwater habitats crucial for invertebrate and aquatic species are being adversely affected, potentially leading to a decline in populations.

Welsh rivers are facing a rapid decline in overall health, with the plight of the endangered salmon population serving as a dire warning. The latest NRW report showed that Welsh rivers are at risk of losing their salmon populations entirely. To prevent such an ecological catastrophe, immediate action is required from all stakeholders involved.

To address this urgent matter, the North Wales Rivers Trust has reached out to Powys Councils Road & Highways team, urging them to take immediate action. The Trust has requested a discussion to present their findings on water contamination and ensure the removal of the rock salt pile within the next 30 days, given the current climatic challenges of increased droughts and rainfall and high surface run off.

The preservation of Welsh rivers and the survival of endangered species, such as salmon and sea trout, depend on swift and decisive action. It is imperative that all stakeholders come together to protect and restore our precious freshwater ecosystems. By doing so, we can ensure a sustainable future for our rivers and the invaluable biodiversity they support.
