1 KW Cargill, P.A. Geotechnical/Environmental Consultant 6350 Riverside Drive Punta Gorda, Florida Tel: June 2018 Mr. Benjamin Hsu Compliance Assurance Program Florida Department of Environmental Protection, Southwest District North Telecom Parkway Temple Terrace, Florida Subject: May 2018 Semi Annual Groundwater Monitoring s Orange Blossom Disposal Facility, Permit No SO/22 WACS ID No , Polk County, Florida Dear Mr. Morris: This report of the May 2018 semi annual groundwater quality monitoring at the Orange Blossom Disposal Facility (OBDF) was prepared by KW Cargill, P.A. (KWC) and is submitted to the Florida Department of Environmental Protection (FDEP) on behalf of Omni Waste of Polk, LLC (Omni). The purpose of this report is to provide results of the current semi annual groundwater quality sampling at the OBDF in accordance with the subject permit. This report complies with the requirements of Specific Condition Appendix 3, paragraphs 4 and 10 of Permit No SO/22 (Permit) and in accordance with Rule (8) (c) and (d) of the Florida Administrative Code (FAC). The report contains the electronic data deliverable (EDD) compatible with the Florida automated data processing tool (ADaPT). The report has been saved in Adobe pdf format and delivered via electronic mail in accordance with permit instructions. The Water Quality Monitoring Certification (31), signed by Mr. Kris Creeden, President of Omni, is included as Appendix A of this report. Semi Annual Groundwater Sampling and Field Testing The semi annual groundwater quality samples for MW 02, MW 03, MW 06, and MW 08 were collected by Mr. Neil Stapley, of Geosyntec Consultants, Tampa, Florida, on 21 May 2018, in accordance with FDEP s standard operating procedures (SOPs), as mandated by GW Monitoring Report.docx 18 June 2017

2 May 2018 Groundwater Quality Monitoring Orange Blossom Disposal Facility Page 2 KW Cargill, P.A. Rule (Quality Assurance), FAC, and DEP SOP (31 March 2008). A summary of all monitoring well construction details and information on four piezometer wells, two previously submitted to FDEP and two additional piezometer wells (P 5 and P 6) recently installed, that were measured during this monitoring event, are included in Table 1 attached to this report for reference. As discussed in previous water quality monitoring reports, the dissolved oxygen (DO) in the groundwater at some wells on the site occurs naturally at higher than 20 percent of saturation (i.e., 1.5 to 2.0 mg/l, depending on water temperature). As a result of high DO measurements, the criteria for field measurements as provided in Section 3.1 of FS 2212 (DO less than 20 percent of saturation) could not be met. Therefore, the criteria for field measurements from Section 3.2 of FS 2212 were followed (i.e., the range between the highest and lowest values for the last three measurements cannot exceed the following criteria: ±0.2 o C for temperature; ± 0.2 standard units for ph; ± 5% of reading for specific conductance; ± 0.2 mg/l for dissolved oxygen; and ± 5 NTUs for turbidity). These criteria were met for MW 02, MW 03, MW 05, and MW 08 as shown on the sampling logs included as Appendix B to this report. Additional information required by Section 3.2 of FS 2212 when high DO is found in field measurements is provided in the table included below.

3 May 2018 Groundwater Quality Monitoring Orange Blossom Disposal Facility Page 3 KW Cargill, P.A. A decontaminated electric submersible pump was used to purge and sample the groundwater in monitoring wells MW 02, MW 03 and MW 08. A peristaltic pump was used to purge and sample MW 06. During the purging process, a YSI 556MPS, serial number 11G100864, water quality meter equipped with a flow through cell was used to monitor the following field parameters: ph; temperature; specific conductance; oxidation reduction potential (ORP); and DO. Turbidity levels were measured using a La Motte 2020we, serial number , turbidity meter. The water quality monitoring instruments were calibrated before sampling commenced and calibration was rechecked after the sampling event. The calibration form for these instruments is included as Appendix C to this report. Field parameters were recorded on groundwater sampling logs (Form FD ), which are included as Appendix B to this report. When the field parameters stabilized within the acceptable tolerances required by the FDEP SOP, well purging was considered complete and groundwater samples were collected from each well for laboratory testing. Filled sample bottles were placed in a cooler (Cooler ID: OBDF for MW 02/03/06/08) and packed with bagged ice for transport to the analytical laboratory. The field results also have been saved as an EDD using the ADaPT software and are included with the electronic report provided to FDEP. The sample coolers were delivered by Mr. Stapley to the representatives of the analytical laboratory as identified on the Chain of Custody (COC) forms attached to this report in Appendix D on the same day as the collection of samples. The sample coolers were received by the laboratory on 21 May Sample Analyses The groundwater samples were analyzed for constituents as required in the OBDF permit by. of Tampa, Florida (AEL) in accordance with the National Environmental Laboratory Accreditation Conference (NELAC) standards The branch laboratory performing the testing holds a certification from the Florida Department of Health (FDOH) for the analytical test methods used for this project and is certified in the State of Florida for analysis of environmental samples. AEL holds FDOH Certification No. E This sampling event analyses were performed in accordance with the routine sampling protocol of the 2015 revision to Chapter (8) (c), FAC. Therefore, the GW Monitoring Report.docx 18 June 2018

4 May 2018 Groundwater Quality Monitoring Orange Blossom Disposal Facility Page 4 KW Cargill, P.A. groundwater samples were analyzed for total ammonia as nitrogen (N), chlorides, nitrate, sulfate, total dissolved solids (TDS), xylene, aluminum, arsenic, cadmium, chromium, iron, lead, mercury, sodium, and those parameters listed in EPA Methods 601 and 602. Other required parameters (i.e., ph; turbidity; temperature; specific conductivity; and dissolved oxygen) were measured by Mr. Stapley in the field during collection of the groundwater samples. The static water level relative to the top of the well casing before purging, as well as any colors or sheens were also recorded by Mr. Stapley. Analytical Testing s The analytical laboratory test results prepared by AEL for the May 2018 semi annual groundwater monitoring for MW 02, MW 03, MW 06, and MW 08 are attached to this report as Appendix E. AEL has also prepared and saved the laboratory results as an EDD using the ADaPT software and those files are included with the electronic report provided to FDEP. The constituents specifically noted for the routine testing protocol in the permit or with detections above the method detection limits for each of the monitoring well samples are summarized in Table 2 attached to this report. Any parameters exceeding the groundwater maximum contaminant levels (MCL) or secondary maximum contaminant levels (SMCL) are highlighted in the table. Those constituents exceeding MCL/SMCL limits are discussed below. ph A low ph in all wells has been typical throughout the site s history and results again are below the SMCL of 6.5 to 8.5 (standard units) in the background well, MW 02 (ph=4.55), and the detection wells, MW 03 (ph=4.20), MW 06 (ph=4.32), and MW 08 (ph=4.47). These measurements are lower than the previous sample measurements in MW 02, MW 03, and MW 06 and higher in MW 08. The low ph appears to be naturally occurring at the site, and has been routinely measured in all wells at the site in all previous monitoring events. The naturally low ph is probably due to the rapid infiltration of rainfall and a lack of buffering through the very clean, silica sands at the site. Aluminum The SMCL for Aluminum (200 μg/l) was again exceeded in all detection wells in this event including in in the background well. The exceedances are no doubt due to the relatively low ph in the wells at this site. The background well, MW 02, was measured at 210 μg/l, which is higher than the previously measured GW Monitoring Report.docx 18 June 2018

5 May 2018 Groundwater Quality Monitoring Orange Blossom Disposal Facility Page 5 KW Cargill, P.A. concentration of 160 μg/l. The SMCL was also exceeded in detection wells, MW 03 (850 μg/l), MW 06 (750 μg/l), and MW 08 (1200 μg/l). These results represent an increase in MW 02, MW 03, and MW 06 and a decrease in MW 08. Elevated Aluminum concentrations have been previously found in all wells, including the background well (MW 02), above the SMCL. The high levels in the wells correspond to the very low ph in the wells, and the source is most likely the Aluminum contained in the silica sands at the site. Nitrate The MCL for Nitrate (10 mg/l) again was exceeded in the routine testing for MW 08, (15 mg/l) for this event. There have been previous exceedances of Nitrate in all wells, both background and detection, thought to be due to influences from the citrus grove to the west of the site. Fertilizer used on the landscape buffer at the OBDF may also be a source of the Nitrate. The sandy soils native to the site offer very little to no buffering of rainfall infiltrating directly to the surficial aquifer. Conclusions and Recommendations The analytical results of this sampling event have been very similar to all previous analytical results. The primary exceedance of criteria continues to be confined to ph and Aluminum, and Nitrate. The detection well most directly affected by the waste pile, MW 06, continues to exhibit very low concentrations of constituents of concern as was the case for former wells, MW 04 and MW 05, which were also located immediately downstream from the major portion of the waste. KWC recommends that semi annual groundwater sampling continue. Groundwater Potentiometric Surface During each groundwater monitoring event, groundwater elevations are measured at each monitoring well and at each piezometer maintained at the OBDF as required by the permit. (It is noted that two additional piezometers have been installed at the site and will be incorporated into the record of potentiometric surface.) A record of these groundwater elevations is presented in Table 3 of this report. The data presented in Table 3 represent only those measurements made since Omni became the facility operator in Historical groundwater elevations prior to 2008 can be found in the Groundwater Monitoring Technical Evaluation Reports previously submitted to FDEP. The water level data from the 21 May 2018 measurements were used in plotting the groundwater potentiometric surface indicated in Figure 1 of this report. All groundwater GW Monitoring Report.docx 18 June 2018

6 May 2018 Groundwater Quality Monitoring Orange Blossom Disposal Facility Page 6 KW Cargill, P.A. level measurements were made within an approximate 4 hour period. The potentiometric surface indicates that groundwater flow is generally from the southwest to the northeast across the disposal facility site. The northeasterly direction is consistent with the direction of groundwater flow measured and reported for previous monitoring events and also those summarized in the previous Groundwater Monitoring Technical Evaluation Reports. Closure This report of semi annual groundwater quality results for MW 02, MW 03, MW 06, and MW 08 at the OBDF is intended to comply with the requirements of the permit. If additional information is needed, or if questions regarding the information presented in this report arise, please do not hesitate to contact the undersigned at or by at kwcargill@earthlink.net.
