During the tests the following sample sizes will be used:
1) Untreated water (control, T0 and T5): Sampling is conducted in-line, three times,
with sample volumes of 20 L (>50 µm), 10 L and 2x 1 L. The 10 L samples are
used to subsample for abiotic variables. The 1 L samples are used (1) to subsample
for phytoplankton, bacteria, as well as for phytoplankton <10 µm and (2)
microzooplankton (10≤µm<50). An additional 10 L sample is taken for an
incubation experiment (T0 only).
2) Treated water (intake, T0): Sampling is conducted in-line, three times, with sample
volumes of 1 m3 (>50 µm) using 3 IBCs of 1000 L each. Furthermore, in-line
sampling is conducted three times with a sample volume of 10 L and 2x 1 L. The
10 L samples are used to subsample for abiotic variables. The 1 L samples are used
(1) to subsample for phytoplankton, bacteria, as well as for phytoplankton <10 µm
and (2) microzooplankton (10≤µm<50). Additional samples of 10 L are taken for
incubation experiments.
3) Treated (discharge, ≥T5): Sampling is conducted in-line, three times, with sample
volumes of 1 m3 (>50 µm) using 3 IBCs of 1000 L each. Furthermore, in-line
sampling is conducted three times with a sample volume of 10 L and 2x 1 L. The
10 L samples are used to subsample for abiotic variables. The 1 L samples are used
(1) to subsample for phytoplankton, bacteria, as well as for phytoplankton <10 µm
and (2) microzooplankton (10≤µm<50). Additional samples of 10 L each are taken
for incubation experiments.
The (sub)-sample volumes taken from the in-line samples deviate from §2.3.32-33 (G8guideline): 10≤µm<50: 1 L for untreated water and 10 L for treated water; bacteria: 0.5
L. Note that G8 only specifies sample sizes, but not which volume of these samples should
actually be analysed. The reason for this deviation is that sample volumes of 10 L for
organisms 10≤µm<50 and 0.5 L for heterotrophic bacteria are impractical: much smaller
volumes will eventually be analysed without compromising the analytical accuracy. The
sample volumes for pathogenic bacteria are 300 and 600 mL.

Abiotic variables: sampling and storing

The measurement of the following abiotic (environmental) variables is required during
sampling (G8 § 2.3.25):
1) salinity,
2) temperature,
3) Particulate Organic Carbon (POC),
4) Total Suspended Solids (TSS),
