ДИРЕКТИВА СОВЕТА N 1999/31/ЕС ПО ПОЛИГОНАМ ЗАХОРОНЕНИЯ ОТХОДОВ. Директива. Европейский Союз. 26.04.99 1999/31/ЕС

C. Trigger levels

     Significant  adverse  environmental  effects,  as  referred to in
Articles  12  and  13  of this Directive, should be considered to have
occurred in the case of groundwater, when an analysis of a groundwater
sample  shows  a  significant change in water quality. A trigger level
must  be  determined  taking  account  of the specific hydrogeological
formations  in  the  location of the landfill and groundwater quality.
The trigger level must be laid down in the permit whenever possible.
     The  observations  must  be  evaluated by means of control charts
with  established control rules and levels for each downgradient well.
The  control  levels  must  be  determined  from  local  variations in
groundwater quality.
