Investigation
Reports for water quality exceedances have been conducted by ET
accordingly. 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 all exceedances recorded at WM1, WM2A(a) and WM4 as well as
the exceedances recorded at WM3x during 3 to 18 July 2018 were related to the rainstorm or external inflow of muddy water and unlikely caused by the
works under the Project. The investigation report for exceedances at WM3x on 30
July are still underway by ET and the investigation result will be presented in
next Monthly EM&A Report.
