Ordinance
on the Avoidance and the Disposal of Waste
(Waste Ordinance, ADWO)

¹ The pro­pri­et­ors of land­fills must ana­lyse the col­lec­ted leachate at least twice each year.

² They must ana­lyse the ground wa­ter at least twice each year if mon­it­or­ing is re­quired to pro­tect wa­ters as a res­ult of the hy­dro­geo­lo­gic­al con­di­tions. For Type A land­fills, ground­wa­ter mon­it­or­ing is only re­quired if they are loc­ated above ex­ploit­able un­der­ground wa­ters or in the ad­join­ing zones re­quired for their pro­tec­tion.

³ If mon­it­or­ing of the ground­wa­ter is re­quired in ac­cord­ance with para­graph 2, pro­pri­et­ors must en­sure that ground­wa­ter samples may be taken in the im­me­di­ate vi­cin­ity of the land­fill or the com­part­ment, and if pos­sible at three loc­a­tions in the down­stream area and one loc­a­tion in the up­stream area.

⁴ They must doc­u­ment the ana­lyses and sub­mit the res­ults to the au­thor­ity.
