RIVM Report 711701048
Soils contaminated with volatile substances can affect the air quality in buildings located in the vicinity of these substances. This guidance describes measurement techniques and the corresponding risk assessment of volatile substances in air caused by soil pollution. The results form the basis for soil decision-making on remediation by the local authorities. The guidance describes in seven steps how health risks from volatile substances in contaminated soil can be assessed using air measurements in and around the house. Possible areas for taking measurements are the living room, the area under the ground floor and in the soil itself. For this, an effective study strategy is important. Before risk assessors begin measuring, they need to first determine whether it is worthwhile. Subsequently, they need to determine target and pre-condition prior to proceeding with measurement. This method is more effective than first measuring and subsequently adjusting target and pre-conditions. The report provides general instructions for the interpretation of obtained data. This guidance is not meant as a rigid protocol but as an aid for all who have to carry out the measurements and interpret results. Furthermore, the guidance can help those who have to decide about taking remedial measures based on risk assessment.
