Comments on Technical guideline for Soil monitoring
Contents • Summary of technical guideline • Reviews • Recommendations
I Summary Objectives • To provide detailed technical guidelines for the procedure of monitoring of the • contaminated soil Scopes • Detailed technical steps for soil monitoring • Reporting monitoring data and results Classification of Land in view of chemical contamination 1 Land used for agricultural purposes 2 Land used for forestry purposes 3 Land used for residential and recreational purposes 4 Land used for commercial and service purposes 5 Land used for industrial purposes
I Summary Soil contaminants + 39 pesticides including Atrazine Classification of contaminated soil
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 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 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 1 Strengthen policy of Protection of public health and precaution 2 Establish rational foundation of soil management 3 Develop soil & groundwater technologies and human resources 4 Promote the soil environment industries for green growth Establish cooperative soil conservation system and international cooperation 5 Key Projects • Expand the nation’s role on soil remediation • Establish soil bank • Make a remediation fund, National Priority list • Manage soil & groundwater together • Run soil & groundwater monitoring network • Develop system and policy • Promote the soil environment industry • Research project to develop technologies • Establish and run a soil bank • Expand performing a risk assessment • Make a remediation level from the assessment • Develop the technologies for risk assessment
