I Summary
Technical guidelines
1 Basic survey
- Determine possibility of contamination
- Review data, Interview and site visit, etc.
2 General condition survey
- Find contaminants, overall contamination extent at subject area
- Determine sampling points and analysis items depending on land uses
3 Precise survey
- Delineate extent and volume of contamination based on general condition survey
- Determine sampling points, depth and analysis items depending on land uses
II. Review
II Review
Framework of soil environment management of Korea
1 Soil monitoring
Soil measuring network (MOE) :
- To monitor(identify) soil condition of whole nation
- Monitoring points(fixed) are selected and soil condition is checked in every year
Actual state soil survey (local government) :
- To detect soil contamination of concerned area in early stage
- Select concerned area (not fixed points, area) and conduct survey in every year
- industrial area, mine area, waste dumping area, etc.
Leakage test and soil contamination test (owner of specific facilities)
- To detect soil contamination of specific facilities in early stage
- Duty of owners of the facilities
II Review
Framework of soil environment management of Korea
2 Soil survey (investigation)
Detailed soil survey (Responsible party) :
- To delineate extent and volume of contaminated area
- Area which is identified contamination from soil measuring network, actual state of
soil contamination survey, and where accidents take place
Soil environment assessment :
- To examine soil contamination when the site installed the specific facilities is
transferred(taken over), rented(taken on lease)
- Not compulsory
Risk assessment :
- For the area owned by nation and naturally contaminated area
- Determine extent and period of remediation considering the results of risk
assessment
- Establish committee to verify results of risk assessment
II Review
Framework of soil environment management of Korea
3 Verification of soil remediation and monitoring soil condition after remediation
Verification of soil remediation :
- To verify remediation process and remediation results
- Determine number of sampling and analysis items depending on contaminated
extent and remediation methods
Monitoring after remediation :
- For the remediated site which was or has been installed specific facilities
- Check soil condition for 2 years after remediation
II Review
Comments on the technical guidelines
1 Objectives
“to identify areas at risk of contamination or already considered as contamination ones,
and to be included in the monitoring programs”
▷ To identify areas at risk of contamination, Soil monitoring is needed
such as soil measuring network and actual state survey of Korea
▷ To identify areas already considered as contamination ones,
Detailed soil survey is needed (delineate the extent of contamination)
2 Monitoring area
“areas which have high potential of contamination, including factories and industries,
waste landfills or incineration, metal mining, including areas where accidents and public
grievances take place frequently”.
▷ Needed to select proper monitoring area depending on its objective
II Review
Comments on the technical guidelines
3 Technical guidelines
▷ Similar to detailed soil survey of Korea
▷ Guideline to delineate the extent of soil contamination after identifying the
contamination
4 Others
▷ Monitoring frequency
▷ Monitoring agencies that performs sampling and analysis
▷ Criterion on management of documents
5 Following steps
▷ In case that contaminated area (Heavily, Medially, or Mildly) is identified,
What is next step? How to manage the contaminated land?
III. Recommendation
III Recommendations
- Phase-in of the soil management policy is needed.
ex) from soil monitoring of nationwide & actual state survey on the risk area
- Considering land uses and its area, periodically check the soil condition at the
selected points
★ Useful for basic data to make policies by determining the background level
of Vietnamese soil and contamination level for soil management.
- This guideline can be applicable to delineate the extent of contamination
- Soil contaminants
Considering Vietnamese industries, more items related with oil(TPH, BTEX, etc.)
and hazardous chemicals(CN, Phenol, TCE, PCE, etc.) are going to be introduced
III Recommendations
A master plan of soil conservation in Korea (2010 ~ 2019)
Vision
Make healthy soil environment to achieve a green society
5 Projects
