FIELD SCREENING AND SOIL-GROUNDWATER PATH ASSESSMENT ACCORDING TO THE ORDINANCE ON SOIL PROTECTION AND CONTAMINATED SITES (BUNDES-BODENSCHUTZ- UND ALTLASTENVERORDNUNG, BBODSCHV)

摘要

Screening methods permissible under BBodSchV represent a suitable, fast and cost-effective contribution to 1. determining the type of contamination (substances, concentration levels), 2. localising the contamination source, 3. determining the extent of horizontal and vertical contamination spread. Screening methods are therefore also suitable for determining sampling points and depths for objective seepage forecasting. Because of this they can be designated for risk assessment of the soil-groundwater pathway and reduce the need to us the more precise laboratory analysis. In this way, an important contribution to a strategically meaningful and efficient assessment of contaminated sites can be achieved.
