<: Under detektionsgrænsen:
Total kulbrinter: < 5,0 µg/l
Benzen: < 0,20 µg/l
Toluen: < 0,20 µg/l
Xylener: < 0,20 µg/l
PAH'er: < 0,050 µg/l pr. enkeltkomponent
Phenoler: < 0,040 µg/l pr. enkeltkomponent
NSO-forbindelser: < 0,020 µg/l pr. enkeltkomponent, dog <1,0 µg/l for pyrrol.
1) Kvalitetskriterium for PAH'er er 0,2 µg/l for 6 MST-stoffer og 1 µg/l for naphthalen.
