Paragraph 4 I1

Northern Ireland Not yet in force

Changes not yet applied. Later legislation changes this provision in ways not yet written into the text below:

Sch. 3 para. 1 coming into force by Landfill 2003 reg. 1
Sch. 3 para. 2 coming into force by Landfill 2003 reg. 1
Sch. 3 para. 3 coming into force by Landfill 2003 reg. 1
Sch. 3 para. 4 coming into force by Landfill 2003 reg. 1
Sch. 3 para. 5 coming into force by Landfill 2003 reg. 1
Sch. 3 para. 4(4) words substituted by Landfill 2004 reg. 7
Sch. 3 para. 6 added by Landfill 2013 reg. 3(3) Sch. 3

(1)

The monitoring of groundwater shall be carried out in accordance with Table 2.

(2)

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.

(3)

In selecting the parameters for analysis, the mobility in the groundwater zone must be taken into account.

(4)

Parameters may include indicator parameters in order to ensure an early recognition of change in water quality (the recommended parameters are pH, TOC, phenols, heavy metals, fluoride, As, oil/hydrocarbons).

	Operational phase	After-care phase
Notes to Table 2 1. If there are fluctuating groundwater levels the frequency must be increased. 2. The frequency must be based on the possibility for remedial action 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 paragraph 5), verification is necessary by repeating the sampling. When the level has been confirmed, a contingency plan set out in the landfill permit conditions must be followed.
