Local hygiene and sanitation inspectors found 21 of the city’s 282 public swimming pools failed to meet the water quality standard.
The pool operators were ordered to fix their problems immediately to ensure the health of swimmers. The city’s swimming pools are teeming with people since mid-July as the weather turned hot.
The inspectors collected 960 water samples from the 282 public pools and 40 from 21 pools failed the test. Their main problems include improper use of chlorine and excessive level of bacteria.
According to the national standard, swimming pool chlorine level should be around 0.4mg to 0.6mg per liter, compared with the International Swimming Federation’s standard of 0.2mg/L because there are usually more people in Chinese swimming pools.
“The Chinese standard can effectively prevent the spread of pinkeye, trachoma, tympanitis and other diseases in the pool,” said Xu Yibo, an expert from the Hangzhou Healthcare Supervision Office.
Hangzhou classifies public swimming pools into three hygiene levels from A to C. People are advised to use the Level A swimming pools. The level sign can be found at the entrance of each swimming pool.
