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.
Rainfall is a major factor affecting beach water quality. Heavy rain may flush pollutants from beach hinterlands into the water causing sudden deterioration of beach water quality. Beaches with inadequate provision of sewerage in the hinterlands are particularly vulnerable to the effect of rainfall. Heavy rainfall may affect the beach water quality for up to 3 days.
Bathers are advised to avoid swimming at beaches during and for up to 3 days after heavy rain. It is also advisable to check the notices at beaches for updated information before swimming.
Leisure and Cultural Services Department has also erected rainfall advisory signs at beaches to remind bathers.
