* Risk-Based levels for MTBE are 45µg/L for residential and 715µg/L for industrial land use classifications.

** PCB Aroclor 1254 and 1260 detection limit must be 1.0µg/L

*** Metal scans must include: Barium, Cadmium, Chromium (total), Lead, Mercury, Nickel, and Zinc.

**** Risk-Based levels for MTBE are 45µg/L for residential and 715µg/L for industrial land use classifications.

Note: For Waste Oil, first run TPH, then if TPH >1000µg/L, run VOC(including MTBE), SVOC, PCB and Metals.

IDEM is currently developing risk-based corrective action guidance.
