B. Monitoring
The parameters to be analysed in the samples taken must be
derived from the expected composition of the leachate and the
groundwater quality in the area. In selecting the parameters for
analysis account should be taken of mobility in the groundwater zone.
Parameters could include indicator parameters in order to ensure an
early recognition of change in water quality <*>.
--------------------------------
<*> Recommended parameters: ph, TOC, phenols, heavy metals,
fluoride, AS, oil/hydrocarbons.

<1> If there are fluctuating groundwater levels, the frequency
must be increased.
<2> The frequency must be based on possibility for remedial
actions between two samplings if a trigger level is reached, i.e. the
frequency must be determined on the basis of knowledge and the
evaluation of the velocity of groundwater flow.
<3> When a trigger level is reached (see C), verification is
necessary by repeating the sampling. When the level has been
confirmed, a contingency plan (laid down in the permit) must be
followed.
