5.3.2 Composite Sampling
Composite sampling is for drawing water samples into one large container.
This is the simplest way of taking samples and typical for most situations
where a sampler is set up to measure effluent in one location. It is also
significantly less expensive than discrete sampling.

5.4 Sinker / Strainer
The intake hose includes either a lead sinker or stainless-steel sinker/strainer.
The sinker or sinker/strainer is intended to keep the sample line fully
submerged in the source liquid. The stainless-steel sinker/strainer should be
used in samples with material that may clog up a normal sinker, or where the
standard sinker could stir up bottom sediment.
