2 November 24, 2014 Burt Fleischer Environmental Director Hilmar Cheese Company 9001 N. Lander Avenue Hilmar, CA Subject: 2014 Annual Supply Well Sampling Data Transmittal Hilmar Cheese Company, Hilmar, California Mr. Fleischer: At the request of Hilmar Cheese Company (HCC), Jacobson James & Associates, Inc. (JJ&A) has prepared this 2014 Annual Supply Well Sampling Data Transmittal to provide the results from supply well sampling conducted at, and in the vicinity of, the HCC facility, located in Hilmar, California, as shown on Figure 1 (the Site). The annual supply well sampling was conducted on August 25 and August 26, 2014, in accordance with JJ&A s Annual Supply Well Sampling Work Plan 1 (the Work Plan); the Regional Water Quality Control Board s (RWQCB) response letters dated November 18, 2010, June 25, 2013, and July 16, In addition, the 2014 annual supply well sampling has been conducted in accord with JJ&A s 2010 through 2013 Annual Supply Well Sampling Data Transmittals 2,3,4,5. The following sections describe the tasks conducted during the 2014 annual supply well sampling event and discusses the results ANNUAL SUPPLY WELL SAMPLING SCOPE OF WORK AND RESULTS A total of nineteen (19) private supply wells were sampled during the 2014 annual sampling event. A list of the subject supply wells and their construction details is provided in Table 1. Figure 2 provides the location of the supply wells. The groundwater samples collected from the supply wells were analyzed for the following constituents using the identified analytical methods: Anions: sulfate (SO 4 ), chloride (Cl), and nitrate nitrogen (NO 3 N) by United States Environmental Protection Agency (USEPA) Method 300.0; Cations: calcium (Ca), magnesium (Mg), manganese (Mn), sodium (Na), and potassium (K) by USEPA Method 200.7; 1 JJ&A, Annual Supply Well Sampling Work Plan, Hilmar Cheese Company, Hilmar, Merced County.

Each of the supply wells was purged until water quality parameters stabilized, as summarized in the field monitoring forms provided in Attachment 1. The final set of water quality measurements (obtained during purging activities) correlate to the aquifer conditions and are representative of the samples collected and submitted to the laboratory; these field parameters (i.e., ph, temperature, ORP, turbidity, DO and EC) are summarized in Table 2. Field measurements and groundwater samples were obtained for each supply well at the closest accessible point relative to the well head. The groundwater samples were transferred directly into the sample containers supplied by the laboratory. Samples were labeled and immediately placed on ice (water based) in an insulated cooler and submitted under chain of custody control to a California State certified laboratory. Prior to being preserved, samples to be analyzed for dissolved metals were filtered in the field using disposable 0.45 micron filters. The analytical results are presented in Table 3. Laboratory reports with chain of custody forms are provided in Attachment 2. A summary of historical analytical results for the supply wells is included in Attachment 3. Trend graphs, including historical and current data, for TDS, Cl, and Na are presented in Attachment 4. Quality Control Sampling The quality assurance/quality control (QA/QC) program for HCC includes steps to evaluate the precision and accuracy of the laboratory analytical results and assess the integrity of the field procedures, sample handling, and laboratory procedures. Field QC Samples Field QC samples, including field duplicate and matrix spike/matrix spike duplicate (MS/MSD) samples, were collected during the groundwater sampling event. Two field duplicate samples were collected from supply wells DW 29 and IW 21. A duplicate summary evaluation is provided as Table 4. MS/MSD

4 2014 Annual Supply Well Sampling Data Transmittal, Hilmar Cheese Company, Hilmar, California November 24, 2014 Page 3 of 5 samples were completed on the following supply well samples: IW 17, IW 21, DW 58, DW 27A, and DW 69. The field and laboratory QC samples were included in the data validation. Data Validation Data validation evaluated the precision and accuracy of the analytical results. The procedures used for validating the data are consistent with those referenced in the January 2010 National Functional Guidelines for Inorganic Data Review prepared by the USEPA, with guidance from Region 9 Data Quality Indicator Tables for USEPA Methods 160.1, 200.7, 200.8, 300.0, and and from the Region 9 Data Quality Indicator Tables for Standard Method Data collected were checked for the following: Data completeness; Holding times and proper preservation; Cleanliness of laboratory blanks; Accuracy and precision of laboratory quality control check samples; and, Precision of field duplicate samples. Detailed data validation results are documented in a memorandum corresponding to the specific laboratory reports reviewed during the validation process. The validation memorandum is included as Attachment 5. Where validation results indicated bias or poor quality, data qualifiers were assigned to the respective analytical data. These data qualifiers are appended to the respective data contained within the project database. Data validation flags, assigned during the data validation process, are defined in the Data Validation Report (Attachment 5). Data validation flags indicate when results are considered anomalous, estimated, or rejected. The results from data validation indicate that all the data results are considered usable and did not require any qualification. No data required qualification nor were any data rejected. SUMMARY The water quality data collected during the 2014 Annual Supply Well Sampling event is generally consistent with historical data. It is noted that although the data are variable, most of the wells report stable constituent trends with the following exceptions. DW 29A: Located west (down gradient) of HCC s former primary lands exhibited a continuing increased trend for concentrations of TDS, Na, and Cl (i.e., 1290 milligrams per liter [mg/l], 124 mg/l, and 205 mg/l, respectively). A chart depicting the time versus concentration for key constituents in this well is provided in Attachment 4; and, DW 53: Located north and east (up gradient) of HCC s former primary lands exhibited continuing decreased concentrations of TDS, Cl and Na (i.e., 665 mg/l and 28.5 mg/l, 54.7 mg/l, respectively). A chart depicting the time versus concentration for key constituents is provided in Attachment 4. The trends observed at DW 29A and DW 53 does not indicate that HCC operations are the cause of these trends.
