Urgent Call to Address Rising Phosphate Levels in Wales' Protected Rivers

Recent assessments have revealed alarming phosphate pollution levels in some of Wales’ most cherished river systems, putting ecological health and wildlife at risk. Two additional rivers, Afon Gwyrfai and Afon Eden, have failed to meet phosphate targets, raising the total to seven out of nine Special Areas of Conservation (SACs) that are now in violation. Environmental advocates are calling for immediate action to stem what they describe as ‘unacceptable’ pollution levels.

Natural Resources Wales (NRW) has highlighted the need for interventions in these rivers, citing a broader trend since 2021 when new phosphate pollution targets were implemented. Phosphates, which naturally occur in human and animal waste, can stimulate harmful algal growth and deplete oxygen in waterways, endangering aquatic life. To counteract this, NRW plans to impose development restrictions on the Afon Gwyrfai system.

Despite previous efforts to improve river health, the data shows a concerning trend, with 50% of the 122 water bodies assessed now meeting phosphorous compliance targets, a minor increase from 39% in 2021. Mary Lewis, NRW’s Head of Natural Resource Management, emphasized the collaborative effort required to tackle pollution and protect river ecosystems, while Tim Birch from Wildlife Trusts Wales lamented the deterioration of water quality in key conservation areas. With ecological integrity at stake, the urgency for action is more pronounced than ever.
