Note:
µg/L approximates ppb.
NS = Not Specified in regulation.
NA = Not Applicable (non volatile contaminants).
(1) Two notification thresholds have been
established depending upon potential use of groundwater.
(2) Three generic cleanup standards have been
established depending upon potential groundwater use/exposure: A-
groundwater actual/potential drinking water supply; B- where groundwater
could be the source of vapor emissions to buildings; C- everywhere.
Alternative levels are permissible based upon a site-specific Risk
Characterization.
