Nestle USA, Inc., Ripon, California August 11, 2009 Second Quarter 2009 Site Status Report water samples, and laboratory analysis of COCs. Exceptions to the reporting requirements or deviations from information listed in the MRP are noted below. oo This report refers to some well numbers differently than the well designations contained in the MRP. The designations in this report are based on analysis of geological information. The well designations listed below are consistent with Nestle's MRP revision request dated May, 2007. o M-28B/A(A) in the MRP is labeled as M-28A in this report, o M-28A(A/C) in the MRP is labeled as M-28C in this report, and o M-27A/C in the MRP is labeled as M-27C in this report. oo City wells MW-4 and MW-6 and Neenah Paper Company production wells PW-6, PW-7 and PW-8 were not gauged because those wells lack access ports necessary for water level sounders used for measuring water levels. oo Several private well owners have refused to provide access for monthly sampling. Please refer to Table 5 for additional information. 3.2 EXTRACTION AND TREATMENT SYSTEMS OPERATION AND MAINTENANCE ECM completed the following activities at the domestic wellhead and groundwater extraction and treatment systems during the Second quarter of 2009: oo ECM performed the operation and maintenance (O&M) for two domestic wells with wellhead carbon treatment systems at 5725 Hall Road and 7501 Kiernan Avenue. The systems were sampled twice per month for COCs using EPA method 524.2 and sampled once per month for nitrate. The system at 7501 Kiernan Avenue is also sampled quarterly for chloride and hardness. ECM submits the monthly performance monitoring reports containing the treatment system influent, mid point and effluent samples results to the RWQCB via e-mail on or before the 28th of each following month. Table 6.2 summarizes the analytical results for the months from January through June 2009. Copies of the monthly performance monitoring reports are presented in Appendix C. oo ECM performed weekly O&M checks for the groundwater extraction and treatment system for wells EU-3 and EU-4 at the On-Site extraction and treatment system (Industrial Avenue) and for wells E-2 and E-6 at the Off-Site extraction and treatment system (Stockton Avenue). oo The Off-Site extraction and treatment system was down for just over 1 hour on June 19 for planned maintenance. oo The Off-Site extraction and treatment system was down from June 23 through June 25 and part of June 26 for a total of 78.5 hours for a planned cleaning of the air stripper tower. oo The Off-Site treatment system was 96.25% operational during the Second quarter of 2009. 5
