Class is the classification of
						  the chemical. "ca" indicates carcinogenic effects; "nc" indicates
						  non-carcinogenic effects. Chemicals that have both carcinogenic and
						  non-carcinogenic effects are classified "ca, nc".
* Indicates SRL is based on the
						  chemical-specific saturation level in soil for volatile organic chemicals only.
** Indicates SRL is based on a
						  100% saturation ceiling limit for non-volatile organic chemicals.
1Arsenic standards are not
						  risk-based standards, but based on background.
2Cyanide (free): Free cyanide
						  is a subset of total cyanides. If any ADHS approved method for total cyanide
						  reports a concentration exceeding this standard, further analyses to
						  differentiate free cyanide from other cyanide metal complexes is required.
3Cyanide (hydrogen): If the
						  cyanide concentrations using any method exceed the hydrogen cyanide standard,
						  then hydrogen cyanide vapor samples should be collected at the site.
4PCBs, low-risk mixture: Use if
						  laboratory analysis confirms that the total PCB concentration consists of 0.5
						  percent or less of congeners that contain five or more chlorines and that no
						  dioxin-like congeners are present.
5PCBs, high-risk mixture: Use
						  if only total PCB concentration is reported by any ADHS licensed analytical
						  method, or if laboratory analysis confirms that the total PCB concentration
						  consists of more than 0.5 percent congeners that contain five or more chlorines
						  or that dioxin-like congeners are present.
Bold indicates adequate
						  evidence to classify the chemical as a known human carcinogen.
CASRN is the Chemical Abstract
						  System Registry Number.
