plume due to natural fluctuation of shallow water was observed;
4) Adverse
water quality outside the site boundary was observed while no pollution source
from this Contract was observed and no construction vessel for this Contract
was travelling nearby. Dispersion of sediment plume to the monitoring stations
from the area outside the site boundary (i.e. works area not under and related
to HY/2011/09) was also observed.
