Sampling Equipment - <br /> Ioterirnas sampling - - - <br /> g p g probes were used to monitor su ce gases at the landfill <br /> petimcter. . . <br /> Each probe consists of a S-foat long, %-inch diameter stainless steel pipe, with %-utcb holes <br /> stanBred every 2 inches at the bottom 18 inches-to allow for gases-to nu a into the <br /> pointed tip was welded to the crud of the probe for better . probes. A <br /> . penetration. <br /> A ball naive and brass fitting.were irLstalled at the top of cacti probe to contain gas pressures and ; <br /> °#ate instrument hook-up to the probe.The valves were lel}closed <br /> except dming monitoring <br /> or Instrument reading.Each probe is tagged"with-a brass plate and identified as "GP-l" through <br /> "GP-10,% <br /> • t <br /> A trA-90 Landtec Infra-red•Gas Analyzer was used to monitor methane, carbon.dioxide.(Co.,), <br /> and oxygen(02)levels at each probe location.The analyzer was calibrated for methaue,Cps,and <br /> Qz prior to use in the field.,Calibration-logs are-included.in thisreport. <br /> Gas moinitoring <br /> Ambient air meastir6ments of me - <br /> thane, oxygen, carbon dioxide; and bammfAic•pressure-were <br /> taken at each gas probe location. Those readings was recorded and the <br /> eat was - , <br /> c:onnccrcd to-the probe. -The valve was opened and probe-gas pressure naeasuremeuts were taken._ <br /> The probe was them purged for_ twoprobe volumes. .Readings-were then collected at _! <br /> y 3.4- to nd intervals, .a stable reading was .obtained... These ' <br /> Mea=rCmenrS of meihane,oxygen, carbon dioxide,and ambient barometricF <br /> prexstare were theca <br /> recorded- Monirtoring was also conducted at various locations in three building sites for the <br /> Presence Of methane gas Monitoring was conducted at the office trailer at the entrance to the <br /> landM trailer boxes at the service shop, and trader boxes at the transfer building. These <br /> locations were monitored for any gas pockets at the:foundation and near arty opening from the <br /> floor such as piping holes,electrical conduits,or floor cracks- <br /> LYSIi<riET <br /> Lysimatars were sampled using the following staridard protocol: <br /> l. Prior to sampling lysimeters,the pressure-vacuum cqutpment is checked and ctcarted. <br /> 80-F0 t1231OR323 A•12 <br /> 2000 der.Gse hely 14,2000 <br />
