New Citizen Science App To Make Water Quality Monitoring More Accessible

Communities across County Wexford are being encouraged to become citizen scientists and help monitor the health of local rivers and streams.

The River Basin Management Service has launched new guidance and a dedicated Citizen Science Stream Index app, aimed at making water quality monitoring more accessible to the public.

The initiative was launched to mark World Rivers Day 2026 and is open to families, schools, community groups and people of all ages.

Participants can assess the health of local waterways by identifying small aquatic animals known as macroinvertebrates, which can act as indicators of water quality.

The system focuses on six common groups. Stoneflies, flattened mayflies and green caddisflies are generally associated with cleaner water, while leeches, water lice and snails are more tolerant of pollution.

The app allows users to record and submit their findings, helping to build a wider picture of water quality across the country.

Small streams account for more than 75% of Irish rivers and provide important habitats for species including Atlantic salmon and brown trout.

The guidance also highlights ways communities can help protect waterways, including reducing pesticide use, planting riverbank vegetation, conserving rainwater and ensuring septic tanks are properly maintained.

People in County Wexford who want to get involved can contact local Community Water Officer Jennifer Cooney for advice, support and training opportunities.
