|PROGRESS IN MANAGEMENT OF
The term ‘contaminated site’ refers to a well-delimited area where the presence of soil contamination has been confirmed and the severity of possible impacts to ecosystems and human health are such that remediation is needed, specifically in relation to the current or planned use of the site. The remediation or clean-up of contaminated sites can result in a full elimination or in a reduction of these impacts.
The term ‘potentially contaminated site’ includes any site where soil contamination is suspected but not verified and further investigations need to be carried out.
Theprogressinthemanagementofcontaminatedsiteshasbeendesignedto show reduction and elimination of negative effects to ecosystems and human health where environment degradation has been confirmed.
The management of contaminated sites starts with investigation that can further lead to rehabilitation or treatment of contaminated site, measures for its conservation and maintenance and revitalization of contaminated sites.
The indicator shows progress in five main steps:
1) site identification/ preliminary study;
2) preliminary investigation;
3) main site investigation;
4) implementation of remediation measures;
- Number of sites managed up to a certain step out of the five main steps of the indicator.
- Share of economic activities in soil contamination as percentage of sites where the activity is present compared to the total number of sites.
What progress has been made in contaminated sites management and what is the share of economic activities contributing to soil contamination?
The management of contaminated sites in the period from 2005 to 2011 showed progress with regard to the main site investigation, as well as implementation of remediation measures. With regard to completion of remediation measures, no progress has been recorded, i.e. completion of remediation measures has not been recorded in none of the identified hot-spots.
With regard to economic activities contributing to soil contamination expressed in percentage, the highest share belongs to mining and metallurgy with 31.25%, and oil refining and leather manufacturing industry with 6.25%.

In the Republic of Macedonia, identification and preliminary investigations have been carried out with 16 sites, where soil contamination has been detected and those sites have been marked as hot-spots. Main investigations have been carried out with eight sites. Remediation measures have been implemented with three sites, while completion of measures has not been recorded with none of the sites.
With regard to economic activities contributing to soil contamination expressed in percentage, the highest share belongs to mining and metallurgy with 31.25%, followed by organic chemical industry with 12.5% and oil refining and leather manufacturing industry with 6.25%.
- Methodology for the indicator calculation
Data for the indicator calculation was taken from the National Waste Management Plan of the Republic of Macedonia or Special Study Е, and from CARDS 2006 Project concerning development of remediation plans with financial requirements for elimination of industrial hot-spots, as well as Feasibility assessment and development of main technical design for water protection measures in the mine Buchim – UNDP Macedonia.
The estimated shares of economic activities contributing to soil contamination are calculated as e.g. [number of mines contributing to soil contamination]/[total number of sites or sites where soil contamination has been confirmed] х 100.
- Source of applied methodology
According to European Environmental Agency.
- Methodological uncertainty
Although there is a definition of contaminated site, because of the lack of limit values for the concentration of certain toxic chemicals in the soil, it is difficult to determine the exact number of sites where soil contamination has been confirmed.
The assessment of contaminated site depends to a great extent on the individual expert assessment.
All sites where certain industrial/economic activity is performed have not been accounted as sites with determined contamination, although such activities generate chemical substances.
List of relevant policy documents
The Second National Environmental Action Plan of the Republic of Macedonia.
Our country lacks legally prescribed limit values for concentrations of certain contaminating substances in soil and standards for their detection in soil. Generally, the existing legislation is intended to prevent new contaminations.
Soil protection is regulated by several laws, including those concerning environment, nature protection, agricultural land, etc., but there is no soil specific law, with clearly defined institutional responsibilities.
Remediation of tailings, stabilization and re-cultivation of industrial landfills.
