Notes:

1. The values are calculated and presented in depth-average, except for DO

3. NA refers to “Not Applicable” as monitoring is not applicable for that water level

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.)
