APPENDIX A <br /> • <br /> ELEINFgLDER.FIELD ACTIVIM PROTOCOL <br /> The Sampling and Analysis Plan (Kleinfelder, Novemberl, 1994) describes how Forward, Inc. <br /> conducts groundwater monitoring for. WMU A. The information contained in the Plan <br /> supemedes sections related to sampling and analysis in the April 1989 Postclosure Plan, <br /> Addendum #1 and Addendum #2- The discussion of groundwater sampling methods and <br /> procedures discussed in this appendix,Meinfelder Field Activities Protocol,are an excerpt of the <br /> more comprehensive Sampling and Analysis Plan. <br /> GROUNDWATER MONITORING. <br /> Monitoring Wells <br /> Equipment <br /> The groundwater monitoring wells at Forward are equipped with dedicated submerged pumps for <br /> purging and collection groundwater samples.. The field technician performing the grov,adwatcr <br /> i <br /> monitoring will have a list of equipment that-should be available with.which to complete the <br /> monitoring.' The necessary equipment is listed below. This list includes actual equipment q pment used <br /> to purge and sample the wells in addition, to personal protective gear that .must be worn for - <br /> protction and to reduce the potential for cross contamination of the wells and samples: Some of <br /> the equipment used includes various instruments which require cah-bration. Calt'bration' <br /> procedures are discussed below. <br /> Calibration Procedures <br /> Many of the meters that are used in the field must be cah`brated 6 produce reliable results. The <br /> following discusses calibration rationale,procedures, and frequency for the required instruments. <br /> Water Level Indicator <br /> Water level indicators must be calibrated regularly to assure that data is not being measured <br /> incorrectly due to the cable stretching. To calibrate the water level indicator the cable is run out <br /> to its entire length and measured against a tape measure. The 0 point is the point on the 'pro <br /> which completes the circuit when contacted by the water.
