What this verdict means
Safe to swim is the strongest verdict this map gives: a favourable regulator classification, a recent sample, and no discharge signal arguing against it. It is still a snapshot, not a guarantee — water quality changes faster than monitoring does, especially after heavy rain.
Every verdict here is computed from regulator classifications, sample dates, pollution-risk forecasts, and water-company discharge reports — it is not a water test. Absence of a negative signal is not positive confirmation of safety, and conditions on the day (rainfall, currents, cold) matter as much as water quality. Read how statuses are decided.
