The infomaation contained in the Plan <br /> =PCrCedes sections related to sampling anis analysis in the April 1989 Postclosure: Plan, <br /> Addendum #1 and Addendum #2. The 'diss6ussion of groundwater,samp4g methods and <br /> praced*w discussed in this appendix,Kleinfelder Field Activities Protocol,are an excerpt of the <br /> more comprehensive Sampling and Analysis Plan. <br /> GROUND WAS MONITOR[NG- <br /> Monitoring Wells <br /> Equipment . <br /> The groundwater monitoring wells at Forward are equipped with dedicated submerged ptunps for <br /> ping and eollcction groundwater samples.. The I.ield techniciatt <br /> performing the gmuaidwater <br /> monitoring will have a list of cart that-should Pm <br /> with which to c omplete-the <br /> j monitoring.' The necessmy equipmentis rimed below This list includes actual equ4=e nt used <br /> to purge and sample the wells in addition. to personal protective gear that must be_worn for <br /> protection and to reduce the potential for cross contamination of the wens and samples; Soule of <br /> thc ig.itipment used includes various b#rumcnts which require calibration. Cal�t'bration <br /> procedures are discussed below- <br /> Calibration Procedures <br /> Many of the meters that are used in the field must be calibrated to produce reliable results. The <br /> following discusses calibration rationale,procedures, : ency for the required dents; <br /> Eater Level Indicator <br /> Water level indicators <br /> must be calibrated regularly to assure that data is not being measured - <br /> mcorrectly due to the cable stretching. To calibrate the water level indicator the cable is run out <br /> W Its entire length and memund against a tape m 0 point is the point on the probe <br /> which completes the circuit when contacted by the water. 11is completed circuit carnes the <br /> 334838494011231OR32S A-1 J 14 2000 <br /> Copyftk 2Coo KkkuW4,e�1W * <br />
