Start with the official bathing-water service
In England, the Environment Agency service provides designated bathing-water classifications and pollution information. Scotland, Wales and Northern Ireland have their own environmental bodies. These records are location-specific and may not cover every beach or entry point.
Check current pollution and overflow information
Water-company event feeds can show reported storm-overflow activity, but coverage, update speed and interpretation vary. Heavy rain can also increase runoff and affect water quality even when a nearby feed shows no active report.
Understand incomplete data
A source may be delayed, unavailable or outside the area Seyva can match. When Seyva says a check is incomplete or unavailable, treat that as missing information—not as a clean result. Always open the named official provider where uncertainty matters.
Use your senses, but do not rely on them
Visible sewage debris, discoloured water, unusual odour, dead wildlife or warning signs are reasons not to enter. Clear-looking water can still contain contamination, so appearance alone cannot confirm quality.
- Check official advice as close as possible to the session.
- Consider recent rainfall and local runoff.
- Look for beach notices and temporary warnings.
- Avoid entering when the data is missing and local risk is unclear.
- Seek medical advice if you become unwell after contact with polluted water.
