3. EMISSION DATA: WATER, LEACHATE AND GAS CONTROL
Sampling of leachate and surface water if present must be
collected at representative points. Sampling and measuring (volume and
composition) of leachate must be performed separately at each point at
which leachate is discharged from the site. Reference: general
guidelines on sampling technology, ISO 5667-2 (1991).
Monitoring of surface water is present shall be carried out at
not less than two points, one upstream from the landfill and one
downstream.
Gas monitoring must be representative for each section of the
landfill. The frequency of sampling and analysis is listed in the
following table. For leachate and water, a sample, representative of
the average composition, shall be taken for monitoring.
The frequency of sampling could be adapted on the basis of the
morphology of the landfill waste (in tumulus, buried, etc). This has
to be specified in the permit.

<1> The frequency of sampling could be adapted on the basis of
the morphology of the landfill waste (in tumulus, buried, etc.). This
has to be specified in the permit.
<2> The parameters to be measured and the substances to be
analysed vary according to the composition of the waste deposited;
they must be laid down in the permit document and reflect the leaching
characteristics of the wastes.
<3> If the evaluation of data indicates that longer intervals are
equally effective, they may be adapted. For leachates, conductivity
must always be measured at least once a year.
<4> These measurements are related mainly to the content of
organic material in the waste.
<5> CH , CO , O , regularly, other gases as required, according
4 2 2
to the composition of the waste deposited, with a view to reflecting
its leaching properties.
<6> Efficiency of the gas extraction system must be checked
regularly.
<7> On the basis of the characteristics of the landfill site, the
competent authority may determine that these measurements are not
required, and will report accordingly in the way laid down in Article
15 of the Directive.
2.1 and 2.2 apply only where leachate collection takes place (see
Annex I (2)).
