Description: Das Projekt "Evaluation of Sampling Strategies for Cantonal Soil Monitoring Programs" wird/wurde ausgeführt durch: Eidgenössische Technische Hochschule Zürich (ETH), Institut für Terrestrische Ökologie, Arbeitsgruppe Bodenschutz.According to the Swiss law on environmental protection, the cantons have to survey soil fertility in case of indication for contamination. Since soil observation is extremely costly, the efficiency of a monitoring program is of primary importance. The design of such a program refers to the spatial and temporal sampling pattern as well as to the selection of the monitoring parameters, sampling procedures, and analytical methods. In this project, we analyzed and evaluated the results of a preliminary survey in the Canton of Zurich in which a large variety of physical, chemical, and biological parameters had been determined on fifteen different sites. Recommendations were made for the planning and implementation of a network of observation sites with respect to the choice of parameters, sampling strategy and quality control. It was found that standards for the assessment of biochemical and biological parameters were insuffient and that questions related to the spatial and temporal variability of monitoring parameters were in general not adequately addressed. Also the investments in terms of time and workforce required for quality control were found to be inadequate. The main problem however was identified to be that the objectives of the monitoring programme were not stated sufficiently precise.
