soils. Previous studies and investigations of storm water in the area will be identified
including studies directly related to the accident as well as other storm water
and drainage studies such as drainage master plans, non-point source investigations,
and storm water management modeling efforts. Based on the review of past work,
areas of particular concern will be identified and studies and evaluations will be
prepared to define the problem and facilitate design of remediation measures. Parameters
that need to be quantified include contamination sources to other media,
such as surface water and groundwater. Models to be used will include those previously
used for Chernobyl, as well as state-of-the-art models from other sources.
3.3.2.5 Water Remediation Technology Evaluation
This sub-project will provide an evaluation of the different methods for water remediation
applicable to this project. Information will be obtained on existing remediation
technologies and will be combined with the results of the site characterization,
fate and transport modeling, and storm water impact evaluation sub-projects.
The remediation technology information and the results will be used to identify
suitable technology alternatives to remediate unacceptable contamination conditions
for rivers, surface water, groundwater, and storm water. For the purpose of
evaluation, remediation technology performance criteria will be identified using
standards developed for cleanup. Viable technologies for remediation will be identified
and described. Remediation alternatives will be developed using the identified
technologies, and each alternative will be characterized and evaluated in terms of
the performance criteria. Alternatives will be ranked based on the results of the
evaluation, and remediation measures will be recommended. Included among these
measures may be re-routing or diversion of sources, settling and precipitation of
contaminants, restricted use planning, and treatment at the point of use.
3.3.2.6 Water Remediation
Following acceptance and approval of remediation options, the project team will
either implement each approved recommendation or assist MinChemobyl in its implementation.
This sub-project team will provide a remediation technology implementation
plan, identify and acquire resources, implement the selected options,
monitor and control performance of the implementation activities, and perform
post-remediation verification for effectiveness. Periodic progress reports will be provided,
and a post-remediation status report will be prepared.
3.3.2.7 Silt and Sediment Remediation Technology Evaluation
This sub-project will provide an evaluation of the different methods for silt and
sediment remediation. Based on the site characterization and past modeling work,
the areas where silt and sediments may need remediation will be identified. A preliminary
evaluation of these areas will be made to facilitate review of the available
technologies and will include estimates of volumes and generic location (i.e., wetland,
river, or reservoir). In postulating possible remediation options, available technologies
will be reviewed for applicability, environmental impacts, local capabilities,
and costs. Local availability of capabilities and resources will be significant factors
in technology evaluation. For the purpose of evaluation, remediation technology performance
criteria will be identified using standards developed for cleanup. Viable
technologies for remediation will be identified and described. Remediation alternatives
will be developed using the identified technologies, and each alternative will
be characterized and evaluated in terms of the performance criteria. Alternatives
will be ranked based on the results of the evaluation, and remediation measures
will be recommended. These measures may include dredging, capping, treatment,
and disposal.
3.3.2.8 Silt and Sediment Remediation
The result of the site characterization and the silt and sediment remediation technology
evaluation sub-projects will be a set of recommended alternatives for silt and
sediment remediation. This sub-project will provide a remediation technology implenientation
plan, identify and acquire resources, implement the selected options, provide
a performance monitoring and control function for the implementation activities,
and perform post-remediation verification for effectiveness. Periodic progress
reports will be provided, and a post-remediation status report will be prepared.

3.4.1 Biota
The biota of the contaminated area affect dosage to man in two ways: (1) by serving
as a mechanism or vector for the entry of radioactive contaminants into man's
food chain, and (2) by serving as a means of transport from one geographic area or
