Action 6.3

Support projects and programmes that complement regulation to address emerging or novel contaminants in the water environment, e.g. The One Health Breakthrough Partnership on pharmaceuticals and the water industry’s Chemical Investigation Programme.

Objective 1: Accelerate ecosystem restoration and regeneration

Priority Action 6. Enhance water and air quality. Undertake water management measures to enhance biodiversity

Status In progress

Target year for completion 2030

Ecological Contribution Scoring 2

Delivery Update May 2026

Work is underway through SEPA-led monitoring, research and industry collaboration to better understand and reduce environmental pressures, including through pilot projects and mitigation trials.

Current activity focuses on evidence gathering and testing of interventions rather than deployment of large-scale infrastructure upgrades or fully implemented treatment solutions. These programmes aim to inform future regulatory and operational approaches.

Ecological Contribution

SEPA and industry-led programmes are improving understanding of emerging contaminants, particularly through monitoring innovation and targeted pilot projects. These initiatives help identify risks from substances such as pharmaceuticals and test potential mitigation approaches, contributing to the evidence base needed for future regulatory action. However, activity is still largely at the research and trial stage, with limited evidence of widespread implementation or measurable reductions in contaminant levels in the environment. Scaling successful interventions into standard treatment processes and regulatory requirements could significantly reduce emerging contaminant pressures on freshwater ecosystems and improve long-term water quality.
