Water Quality Monitoring

3.5.10    DO and water temperature should be measured in-situ by a DO/temperature meter. The instrument should be portable and weatherproof using a DC power source. It should have a membrane electrode with automatic temperature compensation complete with a cable. The equipment should be capable of measuring:

            DO level in the range of 0-20 mg/l and 0-200% saturation; and

            temperature of between 0 and 45 degree Celsius.

3.5.11    A portable pH meter capable of measuring a range between 0.0 and 14.0 should be provided to measure pH under the specified conditions accordingly to the APHA Standard Methods.

 

3.5.12    The instrument should be portable and weatherproof using a DC power source. It should have a photoelectric sensor capable of measuring turbidity between 0-1000 NTU.

 

3.5.13    A portable, battery-operated echo sounder or tape measure will be used for the determination of water depth at each designated monitoring station as appropriate.

 

3.5.14    A water sampler e.g. Kahlsico Water Sampler, which is a transparent PVC cylinder with capacity not less than 2 litres, will be used for water sampling if water depth over than 0.5m.   For sampling from very shallow water depths e.g. <0.5 m, water sample collection will be directly from water surface below 100mm use sampling plastic bottle to avoid inclusion of bottom sediment or humus.  Moreover, Teflon/stainless steel bailer or self-made sampling buckets maybe used for water sampling.  The equipment used for sampling will be depended the sampling location and depth situations.

 

3.5.15    Water samples for laboratory measurement of SS will be collected in high density polythene bottles, packed in ice (cooled to 4 ºC without being frozen), and delivered to the laboratory in the same day as the samples were collected.

 

3.5.16    Analysis of suspended solids should be carried out in a HOKLAS or other accredited laboratory. Water samples of about 1L should be collected at the monitoring stations for carrying out the laboratory suspended solids determination.  The SS determination work should start within 24 hours after collection of the water samples. The SS analyses should follow the APHA Standard Methods 2540D with Limit of Reporting of 2 mg/L.
