This source
is the new king of screening levels. EPA got all Regions 3, 6 and 9 together
and, in 2009, came up with these. There are residential and industrial
screening levels for soil, air and tap water. EPA regions still have their
old screening levels on their websites but with notices to use these. The
site also contains a Screening Level Calculator to assist in calculating
site-specific screening levels and links to the California Human Health

Part B is the holy grail of screening levels. Simple document that gives the
general risk (intake) equations used in a quantitative risk assessment and
the general equations for screening levels termed PRGs (just a note: people
use the acronym PRGs for preliminary removal goals, preliminary remedial
goals AND preliminary remediation goals....generally we are talking about the
same thing). No actual soil levels but does have the original exposure
default values used in EPA risk assessments and general calculations of the
goals. Examines various pathways and media, though mostly for use with soil.
Some of the inhalation defaults have changed since this was written, but it
is still a must have for those attempting to determine their own screening
levels. |

Site", this is Appendix E – Soil Cleanup Level and Remediation Level
Calculations. These are for this site only but can provide an example for
project managers. |

West
Virginia: Risk-Based Concentrations (RBCs) |
|
Link Needed |
|
|
The
WV Voluntary Remediation and Redevelopment Act used to supply several tiers
of levels from a first tier of standard published values to determining
site-specific values. The Guidance Manual contained RBCs in Appendix C-1;
however, the link is no longer valid. If anyone has links to current WV
levels, please let us know. |

The
WI DNR has some regulations with actual remediation values in Chapter NR746.
For residual petroleum in soils, see Tables 1 and 2 of 746.06, available in
the full NR746 document in pdf form or in the online outline which seems to
have a couple more values listed. For generic soil levels, see
NR720.09(4). For groundwater standards, see Tables 1 and 2 of the NR140
document (pdf or outline). For guidance on conducting site-specific
standards, see NR720. |

This WY
Fact Sheet presents the soil cleanup levels for state's VRP. Industrial
levels are not included but can be obtained and/or determined if
considerations of local land restrictions are accepted by the program. WY
Fact Sheet #13 speaks on GW levels which are MCLs or WY calculated levels. |

known as the "ABC List" but now modified to the New Dutch List.
Here is the "Annex A: Target Values, Soil Remediation Intervention

The
Interdepartmental Committee on the Redevelopment of Contaminated Land (ICRCL)
published the Guidance Note 59/83 in 1983 and updated in 1987(2nd edition).
It set out a number of Trigger Values (threshold and action concentrations)
for contaminants in soil including ten metals, cyanides, sulphates, PAHs and
phenols. Outdated by the CLEA numbers now. |

We
can help. We are senior environmental professionals from government,
industry, and consulting. We started this site as a personal resource to be
used throughout our careers - not associated with any firm or agency - we do
not advertise or take money for this site. Recently, we have been getting
more and more questions to the site on international issues as companies are
expanding globally. We see the need
and do plan to build a streamlined resource for international guidance and
levels in the next year. In the interim, if you find yourself needing
assistance on an issue or site anywhere in the world and can't find it, send
us a confidential email (no company names or street address needed). We have
experience in investigating and remediating sites across the globe. From due
diligence to the newest remediation methods, from community relations to
cultural programs, from screening assessments to toxicity studies following
local, regional and national guidance. The most appropriate person will
contact you and see how they can help you. All is kept confidential. |
