• Conclusion

3. Pollution and Contamination
• In short, there is very little difference between
Pollution and Contamination, especially in
environmental terms.
• Pollution can be considered to be something which
is not welcomed in the environment.
Contamination is more often used to refer to a
substance which has been introduced to another
substance, generally giving an adverse affect.
• Pollution clean-up / remediation of soils or water
would involve exactly the same actions
as Contamination clean-up / remediation.

4. Land Contamination
• Defined as the introduction of a substance into the
land so that its quality and function are adversely
affected.

6. Land Contamination
• In the context of land contamination, there are
three essential elements to any risk
• A contaminant
• A receptor
• A pathway

7. SELECTION AND PLANNING OF
REMEDIATION METHODS
The essential data to be collected as part of site
reconnaissance and site characterization.
Data Details Method of acquisition
1) Site history and land
use pattern
a) Population density within 3 km from the contaminated site
b) Ownership of the land
c) Extent of contamination
Field
2)Geologic and
hydrologic
a) Topography
b) Information on aquifer Field
3) Geotechnical a) Soil sampling and classification
c) Chemical characteristics of soil
d) Soil strength
Field
Lab
Lab
4) Waste a) Water quality
b) Identifying the type of contamination
c) Depth of contamination

8. Site Remediation Steps

9. REMEDIATION METHODS FOR SOIL
AND GROUNDWATER
Based on the toxic level of contaminants and the risk it pose
to the environment, a suitable remediation method is
selected.
• PHYSICO-CHEMICAL METHODS
• Removal and treatment of contaminated soil

10. REMEDIATION METHODS FOR SOIL
AND GROUNDWATER
Vacuum extraction

11. REMEDIATION METHODS FOR SOIL
AND GROUNDWATER
Chemical decontamination

12. REMEDIATION METHODS FOR SOIL
AND GROUNDWATER
Some of other methods are
• BIOLOGICAL METHODS

13. CONCLUSION
1.Despite the absence of a concise regulatory framework to deal with
polluted sites in India, PILs have given the judiciary enormous scope
for intervening in environmental matters and passing severe
penalties against companies that have been found guilty.
2. As for the technologies for remediation, they are expensive but need
to be done for the environmental health and safety.
3. There is a need of further research results with a short cycle of
transition into appliance,well trained execution authorities,
innovative consultants ,consecutive usage of synergy effects, and
cross national dissemination of experiences, research results,
reliable information.
