Abstract An interlaboratory study was conducted to determine the precision and accuracy measurements of USEPA Method 200.7 for the analysis of twenty seven trace metals in water and wastewater. USEPA Method 200.7 is entitled 'Inductively Coupled Plasma-Atomic Emission Spectrometric Method for Trace Element Analysis of Water and Waste'. The interlaboratory study design was based upon Youden's non-replicate plan for collaborative tests of analytical methods. Each of six water types was spiked with three youden pairs of the twenty seven trace metals and analyzed by twelve laboratories using both a hard and soft digestion procedure. The tests water included reagent, drinking, ambient and three industrial wastewaters. The resulting data were analyzed using a USEPA computer program routine entitled IMVS and provided regression equations accuracy, single-analyst precision, and overall precision for each water type/trace metal/digestion procedure.
