Neenah Paper,Inc. <br /> _First-Quarter 2008 Groundwater-Monitoring Report April 30,2008 <br /> Page 6 Of 9 <br /> Pump set up to 20 feet below the surface of the groundwater. Prior to sampling, each well was <br /> • purged of three casing volumes of water or until field parameters stabilized. Purged water from <br /> wells TH-7 through TH-10 and wells M-7-A, M-11-A, M-I 1-C, and M-19-C were transported <br /> to Nestles' Stockton Avenue groundwater-treatment system in Ripon for disposal because TCE <br /> or various TCE daughter products have been detected in these wells. Purged water from all <br /> other wells was disposed by direct discharge to the ground surface and allowed to <br /> infiltrate/evaporate. <br /> Sample collection <br /> Groundwater samples were collected directly from the discharge pipe from the submersible <br /> pump. The samples were stored on ice in a cooler, and delivered under chain-of-custody to BC <br /> Laboratories, Inc. in Bakersfield, California for analyses. <br /> Field analyses <br /> Field analyses for temperature, conductivity, and pH were performed on groundwater samples <br /> using a Cole-Parmer portable pH/conductivity meter(model number 19825-00). Turbidity <br /> measurements were performed on groundwater samples using a Cole-Partner turbidimeter <br /> (model number A391-50; Table 2). <br /> Laboratory analyses <br /> Groundwater samples submitted to BC Laboratories, Inc. were analyzed for pH, conductivity, <br /> TDS, sodium, sulfate, chloride, and nitrate (Table 3). <br /> Summary tables of field and laboratory parameters are presented in Attachment A; time-series <br /> • graphs of field and laboratory parameters are presented in Attachment B; laboratory data sheets <br /> and chain-of-custody forms are presented in Attachment C; and L&A field notes are presented <br /> in Attachment D. <br /> • <br /> 005194.01 Task 8 <br /> W.•IClientslFoxRiver-NeenahlQuartertyMonitoring12008llstquarterllstQ2008reparLdoe Lawrence&Associates <br />
