1 The sampling kit for discharge line sampling
should in minimum consist of:
- net or sieve to concentrate sample (with replacement material
of identical mesh size);
- at least two containers to measure water volume extracted from
discharge line. The container is further needed to collect sieved
water for rinsing sieve or net when sampling is completed;
- water appropriate for rinsing net or sieve;
- funnel to ease filling of sample container;
- sample containers including sterile containers for microbial analysis;
- all necessary forms including sample data reporting/chain of custody
forms;
- toolkit to enable net or sieve replacement, etc.;
- tape to seal the sample jar lid to the jar; and
- first aid kit.
2 The sampling kit for manhole sampling should
in minimum consist of:
- plankton net with an associated flow meter − scientific
trials have shown that plankton nets equipped with a cone shaped opening
and filtering cod-end provide the most accurate samples. Nets to be
lowered down into the tank should further not exceed 1 m in length
and 30 cm in diameter to reduce the risk to become entangled inside
the tank. A spare net including an extra cod end should be added to
the sampling kit in case damages occur. A weight (minimum 1 kg) should
be used to keep the wire vertical during the net haul;
- rope to lower down net (the rope should be metered to document
net haul depth);
- net or sieve to concentrate sample (with replacement material
of identical mesh size) spare sieves with identical mesh size should
be added to the sampling kit in case damages occur;
- collecting sieved water for rinsing sieve and plankton net when
sampling is completed;
- water bottle to rinse net or sieve;
- funnel to ease filling of sample container;
- sample containers including sterile containers for microbial analysis;
- all necessary forms including sample data reporting/chain of custody
forms;
- toolkit to enable net or sieve replacement, etc.;
- tape to seal the sample jar lid to the jar; and
- first aid kit.
3 The sampling kit for sounding or air pipe sampling
should in minimum consist of:
- pump (e.g., suction, power or air driven);
- hose (optional with weight to ease lowering down the hose);
- net or sieve to concentrate sample (with replacement material
of identical mesh size);
- at least two containers to measure water volume pumped on deck.
The container is further needed to collect sieved water for rinsing
sieve when sampling is completed and to rinse hose;
- water bottle to rinse net or sieve;
- funnel to ease filling of sample container;
- sample containers including sterile containers for microbial analysis;
- all necessary forms including sample data reporting/chain of custody
forms;
- toolkit to enable net or sieve replacement, opening of sounding
or air pipes, etc.;
- tape to seal the sample jar lid to the jar; and
- first aid kit.
