October 2015 Activities - Continued
Site Security and O&M Activities - Continued • Fawcett Engineering was on Site on October 7-8 to assist with the start-up of select FMS pumps
and the installation of a flow meter at FMS Evaporation Pond C.
Site Characterization Activities • Site-wide monthly groundwater elevation measurements were obtained October 26-27 for all
wells. • A Pit Lake water elevation of 4234.00 feet amsl was recorded on October 26, 2015 from the
pressure transducer, an increase of 0.07 feet since September 26, 2015. The pit lake elevation has risen 2.16 feet since October 26, 2014.
• Changes to the Domestic Well Program in October included new owners at DW-30, DW-54, DW-63, DW-136, DW-160, DW-169 and DW-203.
• One new residence (DW-18) was added to the Bottled Water Program and bottled water delivery was re-started to another residence (DW-107) in October 2015.

(GMR), and initiated the compilation of data for the 30 2015 GMR and 30 2015 Domestic Well Monitoring Report (DWMR).
• Performed the 40 2015 groundwater monitoring event October 5-20, which included sampling the six new wells at the B/W-63 well cluster. Samples were collected from the new wells for hydrologic tracer analyses: B34S and B180 in dissolved sulfate, and 234U, 235U and 238U.
• Continued work on the revised Geochemical Characterization Data Summary Report (DSR). • Continued to compile information for inclusion in the OU-1 RI Report, and initiated the
development of a technical memorandum titled Draft Initial Screening of Remedial Alternatives. • Continued to compile information for inclusion in the Bedrock Groundwater Assessment. • Transmitted the Draft Phase 1 Field Sampling and Analysis Plan (FSAP) for OU-7 on October 7. • Routine database management activities in support of Site investigations and monitoring.
Planned November/December 2015 Activities
