Beach Water quality
Weekly Beach Grading in 2009
The beach has mostly achieved Grades 1 and 2 during a bathing season, while occasionally it hovers to Grade 3 and 4.
Behind the beach is the Tai Long Wan Village where a number of village houses are present. Due to the lack of sewerage system around the area, sewage from these domestic premises is treated by septic tanks and soak-away pits. During heavy rainfall, effluent may occasionally surcharge from these systems and increase the amount polluted surface-water runoff, thus it may lead to deterioration of the water quality of the beach.
All gazetted beaches opened to the public during the bathing season are regularly monitored by the EPD. Water samples are collected from each beach for analysing the bacterial level. Based on these results, beaches are classified according to a Grading System to inform the public of the recent bacteriological water quality status. Updated beach gradings are released during the bathing season through weekly press release before weekend, this website and a dedicated telephone hotline (2511-6666). The beach grades are also displayed at the beaches by the Leisure and Cultural Services Department. Beaches are classified into four grades by calculating the geometric mean E. coli level of the 5 most recent sampling occasions and the worst grade is also given to a beach when the last E. coli reading exceeds a high figure.
|2||Fair ||25 - 180||<= 10|
|3||Poor||181 - 610||11 - 15|
|4||Very Poor||> 610 or|
last reading> 1600
# Except where indicated, the E. coli level is the geometric mean E. coli level of the 5 most recent sampling occasions.
