Investigation
Reports for all water quality exceedances were completed by ET. Investigation
results revealed that the Contractor had properly implemented water quality mitigation
measures such as covering the expose area with tarpaulin sheet and provided
bunds align the watercourse. It
was concluded that the exceedances recorded at WM2A(a)
on 8 to 13 January 2018 and WM3x on 8 January 2018 were completed were related
to the impact of rainstorm and not caused by the works under the Project. For exceedances recorded atWM3x on 27 January
2018, it was concluded that the exceedances were related to the external source
of turbid water and not project related.
