Dissolved Oxygen and Temperature Measurement

3.5.12    The dissolved oxygen (DO) measuring instruments should be portable and weatherproof. The equipment should also complete with cable and sensor, and DC power source. It should be capable of measuring:

       A DO level in the range of 0 – 20 mg/L and 0 – 200% saturation; and

       A temperature of 0 – 45 degree Celsius.

 

3.5.13    The equipment should have a membrane electrode with automatic temperature compensation complete with a cable.

 

3.5.14    Should salinity compensation not be built-in to the DO equipment, in-situ salinity should be measured to calibrate the DO measuring instruments prior to each measurement.

 

Turbidity Measurement

3.5.15    The turbidity measuring instruments should be a portable and weatherproof with DC power source.  It should have a photoelectric sensor capable of measuring turbidity level between 0–1000 NTU (for example, Hach model 2100Q or an approved similar instrument).

pH Measurement

3.5.17    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.

 

Water Depth Measurement

3.5.18    A portable, battery-operated echo sounder or an approved similar instrument should be used for water depths determination at each designated monitoring station.

 

Stream Flow Velocity Equipment

3.5.19    Since the EM&A Manuals do not specified instrument to use stream flow velocity measurement, the monitoring of stream flow velocity is therefore proposed to be conducted by using a flow probe which is a digital water velocity meter.

 

Water Sampling Equipment

3.5.20    A water sampler is required for suspended solid (SS) monitoring.  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.

 

3.5.21    For sampling from very shallow water depths e.g. <0.5 m, water sample will be collected from water surface below 100mm using 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.

 

 

Sample Containers and Storage

3.5.22    Water samples for suspended solid should be stored in high density polythene bottles with no preservative added, packed in ice (cooled to 4°C without being frozen) and delivered to the laboratory within 24 hours of collection and be analyzed as soon as possible after collection.

 

3.5.23    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.
