Water quality at South Korea's four biggest water parks is below an international standard set by the World Health Organization (WHO).
The Korea Consumer Agency said this week it had checked water quality at Caribbean Bay, Ocean World, Woongjin Playdoci and Lotte Water Park and found it did not meet the WHO standard. But it did meet the government-set domestic standard.
Data showed water at the recreational facilities had higher combined available residual chlorine than the WHO standard of 0.2mg per liter of water ― 0.64㎎/L for Lotte Water Park, 0.56㎎/L for Caribbean Bay, 0.39㎎/L for Woongjin Playdoci and 0.32㎎/L for Ocean World. This substance is not on the domestic standard's checklist.
Combined available residual chlorine is a toxic cocktail of chlorine (used as a disinfectant) and sweat and urine (from users). This causes eye and skin problems.
No E. coli was found.
