Notes:
1.
The values are calculated and presented in depth-average, except for DO;
2. Monitoring
level: S&M – Surface and Middle; B – Bottom
(* For M1, M2, M3, E2a, E3a, DB1 and SP1 the water depth is less than 3m, only
value at the middle was taken in the baseline monitoring; ** For E1 the water
depth is between 3m to 6m, only value at Surface was taken in the baseline
monitoring.)
3.
NA refers to “Not Applicable” as monitoring is not applicable for that water
level;
a. Four (4) mg/L will be adopted as the
Limit Level (LL) of DO (S&M) at E3a and DB1 since the 1%-ile of baseline data for surface and middle layer is
greater than 4 mg/L;
b. Two (2) mg/L will be adopted as the
Limit Level (LL) of DO (B) at E1, E5a and KT1 since the 1%-ile
of baseline data for bottom layer is greater than 2 mg/L.
