Author: R.I. Crane
Document Type: Monograph
The Environment Agency and the Scottish Environment Protection Agency are the competent bodies required to implement the UK legislation designed to complete transposition of the EC Groundwater Directive (80/68/EEC). Included in the implementation is the classification of substances likely to be discharged to or to otherwise pollute groundwaters. The Groundwater Directive National Advisory Group (GDNAG) was set up to produce a suitable classification system. The system is required to classify substances as either List I (discharge to groundwater unacceptable) or List II (discharge to be controlled to prevent pollution). The classification procedure includes the selection of relevant substances for consideration and then the assessment of whether a substance is a carcinogen, mutagen or teratogen and its aquatic and mammalian toxicity, persistence (in groundwater and soil) and bioaccumulation properties Lists of priority substances were produced, by the group and also suggestions for substance property criteria for classification of which the aquatic and mammalian toxicity criteria were agreed. The aquatic toxicity criterion was that a substance falling within the List I Families/Groups with stringent, robust test data indicating an LC50 or equivalent data of less than 10 mg/l should remain on List I.
