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.
