Table 3.4        Water Quality Monitoring Parameters and Frequency

 

Parameters, unit

Depth

Frequency

In-situ Parameters:

·         Temperature

·         pH

·         Water depth

·         DO, mg/L

·         DO Saturation, %

·         Salinity, ppt

·         Turbidity, NTU

·      3 water depths: 1m below water surface, mid-depth and 1m above sea bed.

·      If the water depth is less than 3m, mid-depth sampling only.

·      If the water depth is between 3-6m, omit mid-depth sampling.

·      Baseline monitoring: once per month for 3 consecutive  months

Laboratory Testing Parameters:

 

·         E. coli, cfu/100ml
