ACD: |
Allergic contact dermatitis |
AP-42: |
air model that generates particulate
emissions data
|
ARS: |
Alternative remediation standard
|
ASTM Method D3987-85: |
This is a water extraction procedure
that the Department is recommending to determine the
solubility of Cr+6 in a given soil or waste
and therefore assess its potential to elicit ACD.
|
Cr+3: |
Trivalent chromium
|
Cr+6: |
Hexavalent chromium
|
Fick's Law: |
a law of chemistry and physics: the
rate of diffusion of one substance in another is proportional
to the negative gradient of the concentration of the
first substance
|
Hexavalent Chromium Analysis: |
The Department strongly recommends
the use of the NJDEP Modified SW846 Methods 3060A
and 7196A for the analysis of soil for hexavalent
chromium. Where background interference is a problem,
the Department uses USEPA Method 218.6 (Ion Chromatography)
in place of NJDEP Modified SW846 Method 7196A.

|
Kd: |
solid-liquid partitioning coefficient
|
LSR: |
The ratio of the volume of extraction
liquid expressed in liters to the weight in kilograms
of soil sample being extracted utilizing American
Society of Testing and Materials Method D3987-85.
|
MET: |
Minimum elicitation threshold
|
Nonresidential land use scenario: |
This represents a typical adult worker
exposure at an industrial site and involves a 8 hour
working day, 250 working days per year over a 25 year
period. This scenario is equivalent to the Restricted
Use scenario in Public Law 1997, Chapter 278.
|
Residential land use scenario: |
This represents a typical child through
adult exposure at a single home location and involves
a 24 hour exposure time, 350 days per year over a
30 year period. This scenario is equivalent to the
Unrestricted Use scenario in Public Law 1997, Chapter
278.

Guidelines for Superfund, Part B.
|
SCC: |
Soil cleanup criteria or criterion
|
SSL: |
Soil screening level
|
Total Cr: |
Total chromium is the sum of the
hexavalent and trivalent chromium forms. Analytically,
it is determined by SW846 Methods 3050B and 6010B
or the USEPA equivalent Method 200.8
|
USEPA: |
United States Environmental Protection
Agency
|
USEPA 1312: |
An extraction procedure simulating the
effects of acid rainfall that is being recommended by
the Department to evaluate the potential impact of Cr+6
on ground water. |
