borehole models SBL/SBH and SBA/SBB, which both contain sections with relatively low
equivalent-uranium concentrations. Model SBH/SBL has now been countersunk at the site so that
data were taken by suspending the probe downhole. Model SBA/SBB is still lying horizontally
above ground at the site, so data were logged as in previous calibrations at the Hanford Site by
pushing the probe into the hole and drawing it out with the logging equipment. A previous
correlation for relating observed count rate in before- and after-logging field calibrations to
equivalent-uranium concentrations was confirmed for field source Ra-20S-82. A computer-based
digital collection/recording system was used simultaneously on many of the procedures with the
original analog system so that the performance of the two collection systems could be correlated
and compared. The digital system was calibrated this year to confirm its linearity and to establish
correlation with the analog data (i.e., chart-recorder output).

for Hanford Site Facilities: Volume 3, Appendices C-G, Progress Report for the Period October
1 to December 31, 1986. PNL-6465, Vol. 3, Appendices C through G, Battelle Pacific North-
west Laboratories, Richland, Washington. ABSTRACT: This volume contains Appendices C
through G. Appendix C contains the geophysical logs for 12 new wells in the 100-H Area. Appen-
dix D contains the Statement of Work, which details the efforts needed to finish construction of the
deep monitoring and observation wells at the Nonradioactive Dangerous Waste Landfill. Appendix
E contains drilling logs, geologists' logs, and construction diagrams for the deep monitoring and
observation wells at the Nonradioactive Dangerous Waste Landfill. Appendix F contains informa-
tion on the hydrogeologic testing plan for new wells at the Nonradioactive Dangerous Waste
Landfill. Included are the text of a presentation concerning this plan and an account of the dis-
cussion that followed. Appendix G contains raw analytical data from a set of samples collected in
October 1986 from wells SM-1 through SM-5 at the Nonradioactive Dangerous Waste Landfill.
8.   Battelle Pacific Northwest Laboratories. 1987. Groundwater Monitoring Compliance Projects
for Hanford Site Facilities. PNL-6467 Vol. 3, Appendix C-I, Battelle Pacific Northwest Labo-
ratories, Richland, Washington. ABSTRACT: Appendix C contains the raw analytical data
collected from the groundwater monitoring networks for the 183-H Solar Evaporation Basins for
December 1986 through February 1987. Appendix D contains information on particle size analysis,
calcium carbonate determinations, soil moisture analysis, and low-permeability unit analysis for
samples from monitoring wells in the area of the NRDW Landfill. Appendix E contains lithologic
logs and well construction summaries for wells in the area of the NRDW Landfill. Appendix F
contains geophysical logs for the wells in the area of the NRDW Landfill. The logs, gamma,
neutron, and density are all plotted on graphs, one graph for each well. Appendix G provides
aquifer test data, including pumping and observation well completions and locations, pumping
rates, drawdown and recovery water-level data, and presentation and discussion of analyses.
Appendix H provides water-level data collected at the Nonradioactive Dangerous Waste Landfill
intended to provide information on the hydraulic gradients (horizontal and vertical) beneath the site.
Appendix I contains measurements and samples taken from the pumping well discharge during
aquifer tests and routine quarterly samples taken during the first two quarters of monitoring.
