Water Quality

The Group Copley World Triathlon is governed by the highest swimming water quality standards of World Triathlon, the international triathlon federation. These have been established in accordance with World Health Organization (WHO) and European public health standards. And good news! Alexandra Basin's water meets all these requirements with flying colors.
