The latest assesment of beach water quality by Hong Kong’s Environmental Protection Department shows a ‘good’ grading for 24 of 39 public beaches across the city.
In the Islands District, Tong Fuk, Upper and Lower Cheung Sha, and Pui O on Lantau Island, as well as Cheung Chau Tung Wan and Kwun Yam on Cheung Chau Island and Hung Shing Yeh and Lo So Shing on Lamma Island received good gradings, indicating an E. colo count of less than 24 parts per 100 ml.
Mui Wo and Discovery Bay were in contrast graded fair, on account of an E. coli reading between 25 and 180 parts per 100 ml, as well as a minor illness rate of less than 10 out of 1000 swimmers.
In other areas with open public beaches, the Tuen Mun District received 1 good versus 5 fair gradings, Tsuen Wan received 2 versus 5, Hong Kong’s Southern District received 8 versus 2, and Sai Kung received 5 versus 1.
No poor gradings were given.
Beach water quality can be monitored on www.beachwq.gov.hk, which posts results on its webpage in about 48 hours after sampling.
Since the bathing season opened in March, periods of rainy weather have been continuously forecast by the Hong Kong Observatory. Showers and thunderstorms are expected to take place across the territory between the 13th and 18th of April.
Heavy rain may affect water quality as pollutants seep into water. As some beaches are more prone, swimmers are advised to keep out of the water for up to 3 days following heavy rain. Hong Kong’s Leisure and Cultural Services Department typically provides warnings in affected beaches.
