All laboratory analyses were performed by Environmental Conservation Laboratories, Inc. of Orlando, Florida (NELAC: E83182). All samples were preserved, documented, and transported to Environmental Conservation Laboratories, Inc. (ENCO) in Orlando, Florida for analyses of the parameters specified in the permit. The laboratory results were also processed by ENCO using Florida DEP Automated Data Processing Tool (ADaPT) software which automates the review of the data for accuracy and consistency. ENCO also provided to NOVA Environmental Services, Inc. with the required ADaPT Electronic Data Deliverables (EDDs) consisting of a Portable Document Format (PDF) and comma separated text files (.csv format) for both laboratory and field data. Subsequent to the completion and submittal of this report, the EDDs were ed to the DEP by NOVA Environmental Services, Inc. to meet the ADaPT reporting requirements specified by DEP. The DEP uploads the electronic data into their Water Assurance and Compliance System (WACS) database which is also made available to the general public. The completed water quality monitoring certification page [DEP Form (31)] is presented as Attachment 1. A copy of the laboratory report, chain of custody documentation, and ground water sampling log are presented as Attachment WATER QUALITY MONITORING RESULTS 4.1 Ground Water Quality On April 25, 2011, one (1) representative ground water sample was collected each from background Monitoring Well MW-1R, compliance Monitoring Wells MW-2R, MW-3, and offsite assessment Monitoring Wells MW-4, MW-5, and MW-6 and submitted for laboratory NOVA Environmental Services, Inc.

5 Freeport C&D Disposal Facility Evaluation Monitoring Report June 30, 2011 Page 7 of 10 analyses for the required evaluation monitoring parameters. Prior to well purging and sampling, static ground water measurements were obtained from all monitoring wells. The total depths all monitoring wells of were measured subsequent to sampling. The monitoring well locations are shown on Figure 1. A summary of the parameters which exceeded the Ground Water Cleanup Target Levels (GTCLs) promulgated in Chapter Florida Administrative Code are summarized on Table 1. As shown on Table 1: Iron (total) in detection Monitoring Well MW-2R (24,900 µg/l) and assessment Monitoring Wells MW-4 (6,900 µg/l) exceeded the GTCL of 300 µg/l. Based on a review of historical data, Iron has been consistently detected above the GCTL in MW-2R since August 2003 and in MW-4 since January 2010 when first installed. The facility is continuing to implement site assessment activities to address the exceedences. As such, notification and confirmation monitoring specified by permit Condition No. s 26 and 29 is not required. Arsenic in detection Monitoring Well MW-2R (684 µg/l) and assessment Monitoring Well MW-4 (54.4 µg/l) exceeded the GTCL of 10 µg/l. Based on a review of historical data, Arsenic has been consistently detected above the GCTL in MW-2R since January 2007 and first shown to be elevated between August 2003 and July 2006 except for between August 2004 and August Arsenic in MW-4 has been consistently detected above the GCTL since January 2010 when initially installed. The facility is continuing to implement site assessment activities to address the exceedences. As such, notification and confirmation monitoring specified by permit Condition No. s 26 and 29 is not required. Sodium in detection Monitoring Well MW-2R (172 mg/l) exceeded the GCTL of 160 mg/l. Based on a review of historical data, Sodium was first detected above the GCTL in MW-2R in January 2009 and sporadically exceeded the GCTL between October 2009 and present. The facility is continuing to implement site assessment activities to the exceedences. As such, notification and confirmation monitoring specified by permit Condition No. s 26 and 29 is not required.

6 Freeport C&D Disposal Facility Evaluation Monitoring Report June 30, 2011 Page 8 of 10 Nitrogen Ammonia in detection Monitoring Well MW-2R (21 mg/l) exceeded the GCTL of 2.8 mg/l. Based on a review of historical data, Ammonia (as Nitrogen) has been consistently detected above the GCTL in MW-2R since January 2005 and first shown to be elevated between February 2002 and August The facility is continuing to implement site assessment activities to address the exceedences. As such, notification and confirmation monitoring specified by permit Condition No. s 26 and 29 is not required. Sulfate in detection Monitoring Well MW-2R (550 mg/l) exceeded the GCTL of 250 mg/l. Based on a review of historical data, Sulfate was first detected above the GCTL in MW-2R in February 2003 and sporadically exceeded the GCTL between February 2003 and present. The facility is continuing to implement site assessment activities to address the exceedences. As such, notification and confirmation monitoring specified by permit Condition No. s 26 and 29 is not required. Total Dissolved Solids (TDS) in detection Monitoring Well MW-2R (2,100 mg/l) and assessment Monitoring Wells MW-6 (520 mg/l) exceeded the GCTL of 500 mg/l. Based on a review of historical data, TDS has been consistently detected above the GCTL in MW-2R since February 2002 and sporadically exceeded the GCTL between February 2003 and present. TDS has been consistently detected above the GCTL in MW-4 since July 2010 after its initial installation in January The facility is continuing to implement site assessment activities to address the exceedences. As such, notification and confirmation monitoring specified by permit Condition No. s 26 and 29 is not required. Field ph in upgradient Background Monitoring Well MW-1R (5.9 Standard Units) and off-site assessment Monitoring Well MW-5 (6.2 Standard Units) exceeded the GCTL of between 6.5 to 8.5 Standard Units. Because the field ph exceedence occurred in the background monitoring well, further sampling/analyses prior to the next scheduled monitoring event is not warranted. The ph value is typical of shallow ground water conditions and G-II ground water classification. 4.2 Surface Water Quality NOVA Environmental Services, Inc.

7 Freeport C&D Disposal Facility Evaluation Monitoring Report June 30, 2011 Page 9 of 10 Representative surface water samples were collected from Surface Waters SW-1 and SW-3, but not SW-2 because it was dry at the time of the monitoring event. The surface water monitoring locations are shown on Figure 1. A summary of the parameters which exceeded the Surface Water Quality Standards (SWQSs) promulgated in Chapter Florida Administrative Code are summarized on Table 2. As shown on Table 2: Iron (total) in upgradient Surface Water Monitoring SW-1 (1,620 µg/l) and downgradient SW-2 (4,500 µg/l) exceeded the SWQS of 1,000 µg/l. The Iron exceedences at upgradient Surface Water SW-1 indicates Iron is naturally occurring. As such, notification and confirmation monitoring specified by permit Condition No. s 26 and 29 is not required. Nitrogen Ammonia in downgradient Surface Water SW-2 (0.42 mg/l) exceeded the SWQS of 0.02 mg/l. Based on a review of historical data, Ammonia has previously been detected in upgradient Surface Water SW-1 at concentrations ranging from and 0.17 mg/l (above the SWQS) indicating Ammonia is naturally occurring.

54 FLAGS/NOTES AND DEFINITIONS PQL B I J K L M N O Q T U V Y Z PQL: Practical Quantitation Limit. s are based upon membrane filter colony counts that are outside the method indicated ideal range. The reported value is between the laboratory method detection limit (MDL) and the practical quantitation limit (PQL). Estimated value. Off-scale low; Actual value is known to be less than the value given. Off-scale high; Actual value is known to be greater than value given. Presence of analyte is verified but not quantified; the actual value is less than the MRL but greater than the MDL. Presumptive evidence of presence of material. Sampled, but analysis lost or not performed. Sample exceeded the accepted holding time. Value reported is less than the laboratory method detection limit. The value is reported for informational purposes only and shall not be used in statistical analysis. Indicates that the compound was analyzed for but not detected. Indicates that the analyte was detected in both the sample and the associated method blank. The laboratory analysis was from an improperly preserved sample. The data may not be accurate. Too many colonies were present (TNTC); the numeric value represents the filtration volume.? Data are rejected and should not be used. Some or all of the quality control data for the analyte were outside criteria, and the presence or absence of the analyte cannot be determined from the data. * Not reported due to interference. E QM-02 QM-07 QM-08 QM-17 The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate (CLP E-flag). The and/or percent recovery for this QC spike sample cannot be accurately calculated due to the high concentration of analyte inherent in the sample. The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. Post-digestion spike did not meet method requirements due to confirmed matrix effects (dilution test). Matrix spike recovery was outside acceptance limits due to high concentrations of analyte in source sample. Page 35 of 36
