The documentation to be presented in the Detailed
Evaluation Report of the soil quality must include:
| A. |
Sampling of soils,
waters and residues: |
 |
| |
Description of field work carried out.
Justification of the parameters analysed,
and also of the sampling methodology, location
and depth of the sampling points so as to guarantee
their representativeness.
Description of the procedures for sampling,
conservation of samples and methods of analysis
in order to ensure the reliability of the results
obtained.
Presentation of the analytical results in
table form.
Graphic representation of the field work
and results: plans showing the location of the
points sampled, lithological columns, maps of
isoconcentrations, pressure measurements (piezometry)
etc.
Appendix with the laboratory analysis bulletins. |
|
| B. |
Detailed investigation of the
physical environment: |
|
| |
Amplification of the geological description,
by means of geological cartography if necessary.
Hydrogeological study: identification of
aquifers, hydrogeological parameters, flow direction,
inventory of water points of the environment
(surface and underground) and map of isopiezes.
|
|
| C. |
Conceptual model of the affection
and migration of the pollution: |
|
| |
Precise delimitation of the focus and
extent of the pollution plume taking the different
vectors into account
Identification and parameterisation of the
transport mechanisms of the pollution that make
it possible to understand how a particular pollution
situation has been reached (characteristics
of the pollutants, characteristics of the unsaturated
area and hydraulic functioning of the underground
waters).
Maps showing the pollutants and their concentrations
and migration.
Graphic representation of the results: maps
of isoconcentrations, pressure measurements
(piezometry), lithological sections etc. |
|
| D. |
Risk analysis and evaluation
of the results: |
|
| |
The minimum items to be contained in the
evaluation of risks associated with polluted
soils are those set out in annex VIII of RD
9/2005.
Calculations to find whether or not the risk
for persons and the environment is acceptable
.
Evaluation of the analysis, conclusions and,
if appropriate, proposal for actions.
The description of the risk analysis methodology
must be detailed and must include all the parameters
used, scenarios considered, starting hypothesis,
transport models of and calculation equations.
Also the justification of the model used as
well as its limitations. |
|
| E. |
Conclusions |
|
| |
Evaluation of the results, conclusions
and, if appropriate, proposal for actions. |
