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
