Early in the quarter the scope of the HSSR for uranium was expanded by the DOE to include the analysis of thorium and lithium in sediment and several other elements selected by the LASL in either sediment or water. Development of the LASL multielement capabilities in the x-ray fluorescence, spectrochemical, and neutron activation techniques was accelerated to achieve the required throughput rate of 200 samples per day by each method early in FY 78. The LASL will report data for 43 elements in sediment samples and 13 elements in water samples. During the quarter, uranium analyses were determined for 7360 sediment samples and 7100 water samples. The priorities and format for HSSR reconnaissance reports were changed to reflect the new DOE guidance received early in the quarter. Reconnaissance report boundaries will coincide with those of NTMS 1:250,000-scale topographic map sheets; existing data bases are being split and combined to conform to these boundaries. Computer output formats and headers for the multielement listings to be used in LASL HSSR reports were developed and are ready to be used on the first multielement report. One reconnaissance report was open filed through the DOE Grand Junction Office. Two NTMS quadrangles were sampled as part of pilot studies; 39 of the 66 quadrangles assigned to the LASL in the lower 48 states have been completely sampled, and bid quotations were requested for sampling all or the remaining parts of the other 27 quadrangles during FY 78. Sampling specifications to be released for bid next quarter were prepared for the 35 quadrangles to be sampled in Alaska in FY 78.
