[en] The control status observation on the water and sediment batch control charts are presented. LLL shows positive bias in their delayed neutron counting analyses of sediments R1, S1, and T1. LASL is showing a downtrend in their fluorometric analyses of water B3. The interlaboratory comparisons of water A3 and water B3 show all laboratories are in good agreement with one another. The comparisons of sediment R1 and S1 show that LLL results are significantly different from other laboratories. The status of interlaboratory comparisons can be found in Table II
