Stabilization/Solidification Processes
for Mixed Wastes
RPD is working in partnership with DOE's Office of Environmen-
tal Restoration (EM-40) and EPA's Superfund Program to investi-
gate technical issues related to treatment processes for low-level
radioactive and mixed wastes. This project is evaluating the
applicability of various stabilization/solidification technologies for
specific types of waste and assessing their performance in terms of
present and projected regulatory requirements. As part of this
project. RPD is validating methodologies and protocols for
evaluating the leachability of radionuclides and organic waste, and
the long-term durability of stabilization solidification. Information
about our publications is listed on the back of this brochure.

In Situ Uranium Chemical Barrier
Demonstration Project
Potable ground-water supplies worldwide are contaminated or
threatened by advancing plumes containing radionuclides and
metals. Drainage from abandoned and inactive mines has con-
taminated ground water with uranium, radium, molybdenum.
arsenic, selenium, chromium, and vanadium, as well as other
radionuclides and metals. RPD is working with the USGS, DOE,
and the Bureau  of Land Management to conduct a field demon-
stration ol chemical barrier technologies for abandoned mine
lands that has the potential to significantly reduce remedial cost
and increase treatment efficiency.


Containment Technology Project
RPD is part of a working group of industry, government, and
academic representatives working to assess the scientific state
and application of containment and related barrier or control
technology systems. The focus is on identifying and evaluating
technologies (such as walls, barriers, floors, and caps) for
containment of pollutants, and on using verification and moni-
toring techniques to demonstrate their effectiveness.
    Technology Transfer
Technology Screening Guide for Sites
Contaminated with Radiation
RPD is developing the guide Technology Screening (hiidc for
Radiooctively Contaminated Sites, to provide site managers with
easy access to critical information on radioactive contamination
cleanup technologies for soil, surface water, and ground water.  The
guide serves site managers as a user-friendly tool for applying
technical information to management decisions.

Radiation Exposure and Risk Assessment
Manual (RERAN!)
RERAM describes the methodology developed by ORIA to
derive ingestion. inhalation, and external exposure radionuclide
cancer slope factors for use in a radiation risk assessment at a
Superfund site. Potential users of RE-RAM are those involved in
the remedy selection and implementation process, including risk
assessors, risk assessment reviewers, remedial project managers.
and other decision-makers.

Technical Support
RPD staff provides technical support and expertise in radiological
contamination to the Superfund Program, private companies, and
states. The Division  supports Superfund remedial technology
projects, participates in interagency workgroups, conducts peer
review of documents, and designs and develops technical informa-
tion products for those involved in cleanup.

   • EPA Badging (Dosimetry) Program
   • Radiation Safety Information Management

 Radiological Emergency Preparedness and Response
 RPD serves as EPA's focal point for radiological emergency
 preparedness and planning.

   • Supports On-Scene Coordinators through the National
     Contingency Plan.

   • Sets Protective Action Guidelines (PAGs) to protect the
     public in the event of a radiological emergency that may
     require evacuation or relocation of citizens.

   * Monitors and assesses radioactivity in the environment.
     Three radiological laboratories maintain the personnel
     and equipment to respond to an emergency through two
     Radiological Emergency Response Teams (RERT).

  Sandia's Environmental Decision
  Support System ISEDSS)
  The SEDSS system is being designed to provide a technically
  sound environmental decision-making framework for federal and
  private environmental restoration and waste management
  problems. EPA, DOE, and NRC are working together to develop
  this system which will provide environmental pathways for both
  radionuclide and hazardous contaminants, and will be integrated
  with site characterization tools.

  Selection of K  Values in Contaminant
  Transport anu Remediation
  RPD is working to provide a documented discussion of the key
  geochemical processes affecting sorption and the use of
  partition coefficients (Revalues) in calculations regarding the
  fate and transport of radionuclide and hazardous metal con-
  taminants. The emphasis is on evaluating the best methods for
  choosing Kd values and providing a resource document for EPA,
  DOE, and NRC technical staff.

  Joint EPA/DOE/NRG Modeling Cuidance
  The Interagency Environmental Pathway Modeling Working
  Group (EPA/RPD. EPA/OSWER, NRC, DOE) has developed a
  series of consensus documents as part of an  overall joint program
  concerned with the selection and use of models that simulate
  the environmental behavior and impacts of radionuclides. See
  the back of this brochure for information on obtaining
  these documents.
