Abstract [sv]

This report is a survey of present guideline values and limit values for materials like earth, polluted earth, soil improvers, sewage sludge, compost etc. The survey covers most of the west European countries and USA, Canada and New Zeeland. The background to the survey is a need from the soil producing companies in Sweden to define what is meant with “soil of good quality”. In the present situation there is no recommendation available which defines a suitable level of nutrients, a maximum level of metals, a maximum level of undesired objects etc. Another reason for the project is that soil producers recent years have been offered different types of rest materials which should be good for soil production, according to the owner of the materials. An explanation to this development is that from the year of 2002 no combustible waste is allowed for landfill and from 2005 organic waste will not be allowed for landfill. Five organisations in Sweden (The Swedish Environmental Protection Agency, The Swedish Water & Wastewater Association, Stockholm Vatten, Swedish Waste Management, and Swedish Peat Producers Association) funded the Swedish Test and Research Institute to develop quality criteria for soil supposed to be used in civil engineering. The quality criteria are supposed to be used for soil of large quantities, not for small consumers as single households. The work to develop quality criteria was divided in two parts. The first part is an international survey of the existing limit- and guideline values for soil and similar materials. This report is the result of that part. The second part is a consensus process were the reference group in the project will suggest a set of criteria to control the content of nutrients, the content of pollutants (organic and inorganic), physical parameters as grain size distribution, and also different quality classes of the soil depending on the end use. The goal is to achieve national widely accepted soil quality criteria for both producers and end users of the material. The results in this report are: · A set of quality criteria, like the aim in this project, was not found anywhere in the survey. As supposed, most regulations aim at controlling unwanted substances in the soil. The only recommendation values about nutrition and some structural parameters were found in a national guideline document for municipalities. · The extent of national limit values for polluted soil was large in the studied countries. The limit values differed a lot between the countries and also the approach to the problem of soil pollution differed. Some countries used a risk-based approach while the others used a set of different quality classes for the soil. · Regarding metals, the selection is quite similar between the countries, but are not so similar for organic substances. Sweden has some substances on the Swedish list that are lacking on the lists of other countries, for example dibromchlormethane, bromdichlormethane, tetrachlormethane and 2,4-dinitrotoluende. The opposite is valid for mineral oil, 1,2-dichlorethane, vinylchloride and DDT etc. · Most of the studied countries have limit values for sewage sludge to be spread on agricultural soil, and also limit values for soil on which the sewage sludge is to be spread. · Many of the studies countries have guideline values for compost. The development in the compost sector differs a lot between the studied countries. Two non-compulsory system have been studied, the EU-flower and KRAV (a Swedish organisation for organic cultivation). The regulation of metals for the EU-flower corresponds completely with the third-party-certification system for compost in Sweden. KRAV has a set of limits for the metal content in soil improvers.
