Ile infvrmatiox, contained in the Plan supercedes sections related to sampling and analysis in the April 1989 Postelosurc Play Addendum #1 and Addendum 92. The 'on of ground sarztplurg methods and Pmcedtuts discussed in this appendix,Kleinfelder Field Activities Protocol,are an excerpt of the more comprehensive Sampling and Analysis Plan. GROUND WATER,MONITORING- Monitoring Wells Equipment The groundwater monitoring wells at Forward are equipped with dedicated submerged pumps for purging and collection groundwater samples-- The field technician performing.the grouzidwater- - monitoring will have a list of equipment that-should available -with-which to complete-the monitoring.' The necessary egsripruent is listed below This list includes actualequipment used to purge and sample the wells in addition to personalpr6tective gear that In be_worn for protection and to reduce the potential for cross conlamination of the wells and sampler ;Some of the equipment used includes various in#ruments which requim calibradom Calibration- procedures are discussed below.
