Swedish National Guidance Manual on Chlorinated Solvent Remediation

Like other industrialized nations, groundwater supplies beneath many industrial sites in Sweden are contaminated with chlorinated solvents. Compared to countries in North America and other parts of Europe, however, chlorinated solvent impacts in Sweden have not attracted much attention until recently. In 2005, the Swedish Environmental Protection Agency (Naturvardsverket) recognized the need for national guidance on chlorinated solvent remediation. To meet this need, they commissioned a project for the development of a Technical Manual for Screening and Selecting Technologies for Remediation of Chlorinated Solvents in Soil and Groundwater and selected an international team of experts, consisting of SWECO VIAK (Sweden), Geosyntec Consultants (USA and Canada), and COWI A/S (Denmark) to write the Manual.

Bioaugmentation Pilot Test for Chlorinated Solvent Impacts in Sweden

High levels of the chlorinated solvents tetrachloroethene (PCE) and trichloroethene (TCE) occur in groundwater beneath a manufacturing facility in southern Sweden. Regulatory authorities have required groundwater remediation, but Swedish environmental consultants have little direct experience with certain in situ remediation technologies.

Development of National Guidance Manual on Bioavailability Assessment in Sweden

Risk assessment at contaminated sites in Sweden currently follows a methodology that includes the use of guideline values, which are not valid for a number of sites. As an alternative to the use of guideline values, the use of a detailed site-specific approach requires an understanding of the bioavailability in soil and sediment.
