RE: Semiannual Groundwater and Surface Water Sampling Report (March 2020) St. Marks Powder, Inc. St. Marks, Florida Facility ID FLD047096524, Permit 0066244/HO/008, Conditions IV-A, B, C, & D
Dear Merlin:
Semiannual (March 2020) groundwater and surface water samples for the Open Burn Unit (OBU) at the St. Marks Powder, Inc. (SMP) facility in St. Marks, Florida (Figure 1) were collected and analyzed, in compliance with the operating permit for the unit. This report is being submitted to fulfill the groundwater and surface water monitoring requirements of the permit for the OBU. As stated in the permit, groundwater and surface water sampling are to be conducted on a semiannual basis. This report covers the first semiannual sampling event for 2020.
FIELD SAMPLING PROGRAM
Surface and Groundwater Sampling
Groundwater and surface water samples were collected respectively on March 2 and 3, 2020. Samples were collected at the locations specified in the permit (Figure 2). TestAmerica Laboratories, Inc. (TestAmerica) completed laboratory analyses of the samples. The laboratory results are included in Attachment A. Sampling was conducted in accordance with the Sampling and Analysis Plan for St. Marks Powder dated November 2011, and the Florida Department of Environmental Protection (FDEP) Groundwater Sampling Standard Operating Procedure FS 2200. One field blank, designated "Field Blank," was collected during the March 2020 sampling event. The field blank was analyzed for all permit-specified analytes except volatile organic compounds. One equipment blank, designated "Equip. Blank," was collected during the March 2020 sampling event. The equipment blank was analyzed for volatile organic compounds.
Investigation-derived waste (IDW), which consisted of purge water from the monitoring wells, was contained in five-gallon buckets and discharged into a sump at the burn pad that drains to the on-site wastewater treatment plant.
OBU monitoring well total depths were measured on March 2, 2020. The well depths on this date were measured at slightly shallower depths (0.6 to 2.0% reduction) than the nominal depths that were recorded when the wells were installed, which may be evidence of the beginning of siltation within the wells. The current permit requires well depths to be measured in March of even-numbered

years, but measurements will be taken during each ensuing sampling event to monitor any further changes in well depth.
SEMIANNUAL SAMPLING RESULTS
Groundwater Flow
Groundwater and surface water levels were measured on March 2, 2020. A summary of water level measurements and the associated water table elevations for this sampling period are included in Table 1. Figure 3 depicts groundwater flow direction based on the March 2, 2020 groundwater levels using the three-point solution method. With some exceptions, water levels in the moat have historically been lower than groundwater levels, with the exception of OLI-3, resulting in groundwater flow toward the moat. On March 2, 2020, water levels in the moat were just below water levels in groundwater, with the exception of OLI-3.
A staff gauge at the West Bridge has been used to measure the surface water level in the moat since September 1999. Historical water level trends are presented in Table 2. Figure 4 shows the well and surface water hydrographs for the OBU for the past ten years.
The horizontal groundwater flow velocity in the vicinity of the OBU was calculated using the Darcy velocity equation:
V= KI/n
K = hydraulic conductivity
I = hydraulic gradient
n = effective porosity
The hydraulic gradient was calculated using water level data from March 2, 2020. Specifically, the hydraulic gradient from OLI-1 to OLI-3 (0.0032 ft/ft) was used. Assuming the effective porosity is 20 percent (a reasonable estimate for silty sand1), and using an average hydraulic conductivity of 0.5 feet per day (ft/day)2, a value of 0.008 ft/day (2.9 ft/year) is obtained for the rate of horizontal groundwater flow within the surficial water-bearing sediments beneath the site. Note that, given the uncertainties in slug test data and the assumed porosity, and the variation of the gradient laterally across the site, actual groundwater flow velocity also will vary laterally. In addition, this calculation does not account for the potential effect of surface water in the moat on the groundwater flow velocity at the monitoring wells.
The geologic interpretations stated within this report have been reviewed and approved by a Professional Engineer with an active license in the state of Florida. The signature and seal of the approving Professional Engineer is included in Attachment B.
Surface and Groundwater Quality Results
1 Walton, W.C., 1970. Groundwater Resource Evaluation. New York, New York: McGraw-Hill, Inc.
2 K value was taken from “Hazardous Waste Facility Construction and Operating Permit Application, Olin Ordnance, St. Marks, Florida”, prepared by ERM-South, Inc., dated September 1993 (Revised March 1996). K value was derived from slug test data in the vicinity of the OBU.
Laboratory reports and chain-of-custody forms are included in Attachment A. Well sampling records providing well stabilization parameters also are included in Attachment A. A summary of surface and groundwater sampling results for the permit analytes detected are included in Tables 3 and 4, respectively. No constituents analyzed during the sampling event were detected over FDEP Groundwater Cleanup Target Levels (GCTLs) or Surface Water Cleanup Target Levels (SWCTLs), with the exception of N-Nitrosodiphenylamine (N-NDPA) in monitoring well MW-2.
Analysis of the sample collected from background well MW-2 in March 2020 indicated an N-NDPA concentration of 10 micrograms per liter (ug/L), which exceeds the FDEP GCTL of 7.1 ug/L. N-NDPA was detected in OLI-2 and OLI-3, but at concentrations below the GCTL.
GCTL exceedances of N-NDPA were observed in monitoring wells OLI-3 and MW-2 also during the September 2019 sampling event, but subsequent resampling conducted at OLI-3 in November 2019 yielded an N-NDPA concentration below the FDEP GCTL.
The detections of N-NDPA during recent groundwater sampling events at wells OLI-3 and MW-2 are believed to be attributable to the migration of N-NDPA-affected groundwater associated with SMP Solid Waste Management Units (SWMUs) 21 and 23, approximately 700 feet northeast of the OBU. Groundwater elevation data indicates the OBU is downgradient from N-NDPA and Diphenylamine (DPA) impacts at the SWMUs. Groundwater monitoring at the SWMUs is conducted quarterly and is reported to FDEP annually in accordance with the Resource Conservation and Recovery Act (RCRA) Operating/Post-Closure/Corrective Action Permit No. 0066244-HO-008.
It is ERM’s understanding that SMP has recently installed additional monitoring wells to better delineate N-NDPA and DPA in groundwater at the SWMUs. Based on existing information, elevated N-NDPA concentrations detected at monitoring well OLI-3 and background well MW-2 are not considered to be related to activities associated with the SMP OBU; however, ERM will continue to review groundwater sampling results from SWMUs 21 and 23 as they relate to future groundwater monitoring events at the SMP OBU.
Quality Assurance/Quality Control
Analytical results for the field blank suggest that adequate quality assurance/quality control procedures were maintained in the field. In their job narratives, the laboratory noted several quality control issues, including insufficient sample volume available to perform matrix spikes/matrix spike duplicates for methods 3520C/8081 and 3535/8330. Additionally, matrix spike recovery was outside of the control limits for method 353.2, and surrogate recovery was outside acceptable control limits for methods 8260B and 8091. Re-analysis was performed outside of holding time with acceptable results for method 8091 on the sample collected at OSW-3. However, these issues are not considered significant, and the laboratory data are considered to be adequate for their intended use. SMP has made arrangements with the laboratory to provide extra glassware for future events to ensure that sufficient sample volume is available for laboratory quality assurance/quality control purposes.
CONCLUSIONS
Results of the March 2020 sampling of surface and groundwater at the OBU indicate permit levels were not exceeded in surface or groundwater samples, with the exception of N-NDPA in background well MW-2. Since concentrations of N-NDPA in MW-2 are not considered to be related to activities associated with the SMP OBU, the March 2020 sampling results indicate that the OBU, as constructed and operated, is meeting the performance goals of the permit.
Please contact us if you or your staff have any questions about the results and conclusions provided in this sampling report.
Sincerely,
Prasad Shetty Partner

Narrative
Receipt
The samples were received on 3/28/2020 9:30 AM; the samples arrived in good condition, properly preserved and, where required, on ice.
The temperature of the cooler at receipt was 3.9º C.
GC/MS VOA Method 8260B: The following volatile sample was analyzed with significant headspace in the sample container: Trip Blank
(660-101220-2). Significant headspace is defined as a bubble greater than 6 mm in diameter. Batch 223231.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
GC/MS Semi VOA
No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
Metals No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
General Chemistry
Method 353.2: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 660-223221 were outside control limits. Sample matrix interference is suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits.
Organic Prep Method 3520C: Insufficient sample volume was available to perform a matrix spike/matrix spike duplicate (MS/MSD) associated with preparation batch 400-484633.
