Our workstream brings together a diverse community of specialists and practitioners passionate about citizen science for water quality. Citizen science plays a vital role in addressing data gaps and strengthening environmental stewardship. In many parts of the world, water quality data are sparse or nonexistent—yet these data are essential to understand pollution levels, assess health and ecosystem risks, and guide actions to restore and protect water bodies.

Our work focuses on Sustainable Development Goal (SDG) target 6.3, which aims to improve water quality, and its associated indicator 6.3.2, which tracks ambient water quality conditions in rivers, lakes, and aquifers. While countries officially report on this indicator through national agencies, our workstream explores the potential of integrating citizen-generated data with regulatory data to support SDG reporting. We are currently testing this approach in collaboration with partners across several countries.

Citizen monitoring efforts—ranging from water sampling to community-based observations—have been shown to enhance environmental awareness and lead to tangible improvements in water quality. Yet, there is currently no formal mechanism for citizen contributions to feed into SDG indicator 6.3.2 reporting. This workstream seeks to bridge that gap. We believe that citizen involvement is not only a valuable supplement to official data but also a powerful force in shaping more inclusive, locally grounded water management.

Each country’s context is unique, and there is no universal approach. Through shared learning and experience exchange, we aim to identify pathways for citizen engagement that align with local realities and priorities. Ultimately, our goal is to help foster stronger connections between national reporting authorities and the communities most affected by water pollution.

We invite you to contribute to this effort by sharing your own experiences through our survey, and to join our growing working group. Together, we can co-develop strategies that elevate the role of citizen science in achieving global water quality goals.
