water (water depth under 150mm)
(^) 24-hour TSP monitoring at AM1b has been temporary suspended since 27
April 2018 as rented land was demolished
and returned to the landlord. Alterative
location to replaced AM1b is being seeking by ET for IEC and EPD approval.

Investigation
Report for all water quality exceedances was completed by ET. Investigation results revealed that the
Contractor had properly implemented water quality mitigation measures such as
well-maintained the wastewater treatment facility and covered the expose area
with impervious sheet. It was concluded that the exceedances were related to the
unknown source of muddy water contributed from outside the project area and not
caused by the works under the Project. Nevertheless, the Contractor was reminded
to fully implement the water
quality mitigation measure
throughout the constriction phase as far as practicable.
