.ISO-Soil Standards for sampling need to be re-drafted.

.Basic requirements for sampling should be given in the annex to the sludge directive.

.The sampling guidance for sludge (ISO 5667-13) requires redrafting.

.The standards for pH, organic matter and dry matter are acceptable.

.The Workshop agreed that the determination of pH in soil should be carried out in 0.01Mcalcium chloride solution..Neither the ISO nor the CEN Standards for the determination of nutrients fulfil therequirements of the draft sewage sludge directive..Additional research and basic standardisation work is necessary for the determination ofpathogens and micro-organisms..ISO Standard 5667, part 15: ’Water Quality Sampling: Guidance on Preservation andHandling of Sludge and Sediment Samples’ fulfils present analytical needs..ISO FDIS 14507: ’Pre-treatment of Samples for Organic Analysis in Soils’ fulfils presentanalytical needs for the determination of organic pollutants in soils..For additional requirements for pre-treatment (e.g. pathogens, physico-chemicalanalysis), harmonisation between Technical Committees: ISO/TC 190, CEN/TC 223, 292and 308 is considered necessary.

.For additional requirements for pre-treatment (e.g. pathogens, physico-chemicalanalysis), harmonisation between Technical Committees: ISO/TC 190, CEN/TC 223,292 and 308 is considered necessary..The present ISO-method for the extraction of heavy metals from soil material does nottake into account present laboratory practice (micro-wave digestion)..The Workshop mainly agreed with ’aqua regia’ for digestion..Analytical determination techniques have to be equivalent (AAS/ICP)..For the determination of nutrients (e.g. secondary nutrients, nitrogen) a horizontalapproach is required..There is a need for pathway-specific methods (leaching/weak extractant) for differentmaterials..The national methods of analysis should be used for organic contaminants indicated inthe table of the draft directive, in relation to the proposed limit values.
