1.0 Introduction and Site Background

This groundwater monitoring report (Report) was prepared by Apex Companies, LLC (Apex) on behalf of NuStar Pipeline Operating Partnership L.P. (NuStar) as part of the continuing response to a gasoline release from a NuStar refined-petroleum pipeline, which occurred in the Quail Crossing Neighborhood (the Neighborhood) of Andover, Kansas (the Site; Figure 1). The activities outlined herein were performed in accordance with the Consent Agreement and Final Order (CAFO) dated May 10, 2013 and in coordination with the Kansas Department of Health and Environment (KDHE) and the Quail Crossing Neighborhood Association. This report summarizes the groundwater monitoring activities conducted from January 1, 2019 through March 31, 2019.

1.1 Background

The pipeline release was discovered in June 2012 after separate-phase hydrocarbons (SPH) were detected in an irrigation well at 2006 N Colt Court. As shown on Figure 2, the NuStar pipeline release location was approximately 80 feet north of the affected irrigation well. Upon the discovery of SPH in the irrigation well, NuStar immediately mobilized to the Site and implemented initial response and abatement activities, including repairs to the pipeline, soil excavation, deactivation of the irrigation well at 2006 N Colt Court, and removal of SPH from the well. 1.2 Pipeline and Site History

Land use at the Site and surrounding areas is residential. As shown on Figure 2, a stormwater retention pond is located near the Site, approximately 250 feet south of the NuStar pipeline. The pipeline is constructed of 8-inch-diameter carbon steel and is used to transport liquefied petroleum products. The pipeline was installed to an approximate depth of 3 feet below ground surface (bgs) in agricultural land in 1959, and the pipeline remained in agricultural and/or undeveloped land until the late 1990s when the development of the Quail Crossing Neighborhood began. As part of the Neighborhood development, the pipeline depth was increased to approximately 6 feet bgs by re-excavating and backfilling with native material. A 100-foot-wide pipeline easement was created along the pipeline pathway for safety purposes during Neighborhood development. The pipeline easement limits development activities near the pipeline. The pipeline location and associated easement boundaries are shown on Figure 2. Residents in the Neighborhood use municipal water for domestic purposes. In addition to the municipal water supply, some residents in the Neighborhood have irrigation water wells that are used for outdoor irrigation and landscape purposes. The irrigation wells range in total depth from approximately 80 to 116 feet bgs. In most irrigation wells, the screened interval extends from approximately 40 feet bgs to the total well depth; gravel filter packs typically extend from approximately 25 feet bgs to the total well depth. Irrigation well locations are shown on Figure 2. 1.3 Activity Summary

Following the initial response activities, NuStar has performed interim remedial actions and investigations. These have included:

• A Comprehensive Investigation (CI) to determine the nature and extent of separate- and dissolved-phase hydrocarbons at the Site (Apex, 2014a);

• Implementation of a comprehensive groundwater monitoring and SPH removal program to evaluate separate- and dissolved-phase hydrocarbon trends;

• A soil vapor extraction (SVE) pilot test to evaluate this technology for addressing petroleum hydrocarbons in the vadose zone soil;

Page 7: First Quarter 2019 Groundwater Monitoring Report NuStar ... · NuStar implemented a soil investigation in the vicinity of the pipeline release in April 2014 to further define the

First Quarter 2019 Groundwater Monitoring Report Page 3 Quail Crossing Neighborhood – Andover, Kansas May 7, 2019 1641-16

• Additional soil characterization following the CI to better assess the lateral and vertical extent of impacted soil in support of soil excavation planning;

• A groundwater treatment pilot test to evaluate the use of an oxygen releasing compound (ORC) in order to address dissolved-phase petroleum hydrocarbons in groundwater;

• A soil excavation to remove petroleum-impacted soil; and

• An expanded groundwater treatment pilot test to further evaluate the use of ORC as a groundwater remedial technology (this expanded pilot test was initiated in July 2016 and data collection was completed in September 2017).

The following paragraphs describe each of these activities. Comprehensive Investigation. As part of the CI, soil and groundwater data were collected from 24 soil borings, 16 monitoring wells, and select irrigation wells. Information obtained during the CI indicated that residual gasoline constituents are present in soil and groundwater in the vicinity of the pipeline release location. Irrigation Well Deactivation. Since the release was discovered, NuStar has coordinated with property owners within the investigation area to deactivate irrigation wells (nine as of the date of this report) and to reconfigure the associated irrigation systems to receive municipal water; NuStar pays municipal water fees for those property owners. Irrigation wells were selected for deactivation based on their location within the investigation area, groundwater quality, the potential that pumping on the wells could influence groundwater conditions, and/or well owner concerns. Irrigation wells that have been deactivated are listed in Table 2 and locations are shown on Figure 2. The irrigation wells have not been permanently decommissioned; therefore, the well owners will have the option of reactivating the wells at a later date. Irrigation Well Monitoring Program. An irrigation well sampling program was initiated in the summer of 2013. In 2013, these irrigation well data were used to determine approximate locations of the proposed monitoring well network. The construction of irrigation wells in the Neighborhood is not conducive to the collection of depth-discrete samples (i.e. typical screen intervals and gravel pack intervals are approximately 75 and 90 feet in length, respectively). Accordingly, the data obtained from irrigation well samples are considered to be qualitative. After the installation of the monitoring wells, the quarterly sampling of irrigation wells has been continued to provide data to well owners. Analytical data from the ongoing groundwater sampling of the monitoring wells are utilized to define the nature and extent of dissolve-phase constituents in the groundwater. The current irrigation well sampling program includes the collection of samples from 10 irrigation wells annually and seven wells quarterly; as it was approved by the KDHE on January 22, 2018 (Apex, 2018a).

First Quarter 2019 Groundwater Monitoring Report Page 4 Quail Crossing Neighborhood – Andover, Kansas May 7, 2019 1641-16

Groundwater Monitoring Program. A quarterly comprehensive groundwater monitoring program was initiated in August 2013; and in 2017, the KDHE-approved quarterly groundwater monitoring program consisted of gauging water levels in wells MW-1 through MW-22 and SVE-1 through SVE-4, the collection and analysis of groundwater samples from wells MW-1 through MW-22 and SVE-2 through SVE-4, and the collection and analysis of groundwater samples from 17 irrigation wells. A proposal to abandon 10 monitoring and pilot test wells and to modify the groundwater monitoring program was presented in the First Quarter 2018 Groundwater Monitoring Report (Apex, 2018c); the KDHE approved that report on July 9, 2018 and wells were abandoned on September 11 and 12, 2018. The current KDHE-approved groundwater monitoring program is shown on Tables 1 and 2 and consists of gauging water levels and the collection of groundwater samples for laboratory analysis from wells MW-1 through MW-4, MW-6, MW-8 through MW-11, MW-13, MW-17 through MW-22, and the collection and analysis of groundwater samples from seven irrigation wells. In addition, samples from 10 irrigation wells are collected and analyzed annually during the third quarter in accordance with the modified Irrigation Well Sampling Program approved by KDHE in January 2018. SPH Removal. An SPH removal program was initiated in June 2013 to address SPH in the subsurface. The SPH program initially consisted of weekly SPH removal and gauging events. A vacuum truck was used to extract groundwater and SPH, if present, from the irrigation well at 2006 N Colt Court during the period June 2013 through January 7, 2015, and approximately 100 vacuum events were conducted over this time period. A modified SPH removal program was approved by the KDHE on January 9, 2015 and implementation began January 14, 2015. The modified SPH removal program is described in Section 2.2. SVE Pilot Test. To evaluate the feasibility of SVE technology for mitigating subsurface petroleum hydrocarbons, NuStar performed an SVE pilot test in December 2013 in accordance with the KDHE-approved Soil Vapor Extraction Pilot Test Work Plan (Apex, 2013). An evaluation of the SVE pilot test results indicated SVE to be a likely candidate for effective remedial technology on the Site. Accordingly, NuStar presented the results of the pilot test and a conceptual SVE system design at a Neighborhood meeting on February 17, 2014. Following the meeting, NuStar submitted the Soil Vapor Extraction Evaluation and Proposed Soil Investigation Report in March 2014 (Apex, 2014b). NuStar modified the conceptual design of the SVE system to reflect Neighborhood feedback. Despite proposed modifications to the conceptual SVE design, Neighborhood representatives cited several reasons for not accepting SVE as a viable mitigation option, including concerns about noise, emissions, and aesthetics. Soil Excavation and Enhanced Bioremediation Pilot Test. NuStar implemented a soil investigation in the vicinity of the pipeline release in April 2014 to further define the extent of gasoline in soil and to evaluate the potential for implementing other remedial alternatives that may be acceptable to the Neighborhood. Analytical data from that soil investigation were presented in the Soil Investigation Report and Proposed Soil Excavation Work Plan (Apex, 2014c), which was approved by the KDHE on August 8, 2014. The work plan portion of the report described proposed excavation methods along with a general excavation design for removing vadose zone soil affected by petroleum constituents. The KDHE approved the work plan and requested a detailed excavation construction plan to document specific methods and materials for the planned excavation. In

First Quarter 2019 Groundwater Monitoring Report Page 5 Quail Crossing Neighborhood – Andover, Kansas May 7, 2019 1641-16

addition to the standard permit requirement for this type of project, the City of Andover required preparation of detailed survey documents and engineering designs as a condition of permitting the planned excavation. Once the City of Andover regulatory process was completed and the design plan approved, the Soil Excavation Work Plan was submitted to and approved by the KDHE in August 2015 (Apex, 2015c). The Soil Excavation Work Plan was implemented during the fourth quarter of 2015; the soil excavation area is shown on Figure 2. On January 7, 2016, the Soil Excavation Results Report (Apex, 2016a), which provides a detailed description of the excavation activities, was submitted to the KDHE and it was approved by the KDHE on March 14, 2016. To evaluate a remedial technology that may be appropriate for treating groundwater at the Site, the Revised Groundwater Pilot Test Work Plan (Work Plan; Apex, 2015a) was developed and submitted to the KDHE in January 2015. After evaluating several groundwater technologies, the Work Plan proposed a pilot test to evaluate enhanced aerobic bioremediation using ORC via injection to the subsurface. The KDHE approved the Work Plan on January 26, 2015; ORC injections were performed, and pilot test monitoring wells were installed during the period of March 10 through 20, 2015. The bi-monthly groundwater monitoring of wells associated with the pilot test was performed during the period March 2015 through February 2016. The methods and interim results of the groundwater pilot test (through June 2015) were reported in the Revised Interim Groundwater Pilot Test Implementation Report (Apex, 2015b) which was approved by the KDHE on August 26, 2015. The results of the pilot test (through February 2016) as reported in the Revised Groundwater Pilot Test Report and Expanded Pilot Test Work Plan (Expanded Work Plan; Apex, 2016c) indicated that the introduction of ORC is an effective method of enhancing aerobic bioremediation. Accordingly, a larger-scale pilot test was proposed in the Expanded Work Plan, which was approved by the KDHE on May 31, 2016; the expanded pilot test was initiated in July 2016 and the data collection portion of the pilot test was completed with the third quarter 2017 groundwater monitoring event. In July 2016, three monitoring wells (MW-20 through MW-22) were installed at the locations shown on Figure 2; the wells were incorporated into the comprehensive quarterly groundwater monitoring program in September 2016. In addition, the monitoring wells were incorporated into the expanded groundwater pilot test. Results of the expanded Pilot Test were reported in the Expanded Groundwater Pilot Test Report, which was submitted to the KDHE on January 24, 2018 (Apex, 2018b), which was approved by the KDHE on February 5, 2018.

2.0 First Quarter 2019 Groundwater Monitoring

The current groundwater monitoring programs for monitoring/pilot test wells and irrigation wells are listed in Table 1 and Table 2, respectively. The irrigation well sampling program was modified in 2018 with the approval of KDHE. A proposal to abandon ten monitoring/pilot test wells and modify the monitoring well network and associated groundwater monitoring program was presented in the First Quarter 2018 Groundwater Monitoring Report (Apex, 2018c), and the monitoring/pilot test wells were abandoned in September 2018 following approval by KDHE. The abandoned monitoring wells are identified on Figure 3 and in Table 1. The current KDHE-approved quarterly groundwater monitoring program consists of gauging

First Quarter 2019 Groundwater Monitoring Report Page 6 Quail Crossing Neighborhood – Andover, Kansas May 7, 2019 1641-16

water levels and collecting groundwater samples for laboratory analysis from monitoring wells MW-1 through MW-4, MW-6, MW-8 through MW-11, MW-13, and MW-17 through MW-22 and the collection and analysis of groundwater samples from seven irrigation wells. The first quarter 2019 groundwater monitoring event was conducted on March 6 through March 8 and included the following activities:

• Gauged and collected samples from wells MW-1 through MW-4, MW-6, MW-8 through MW-11, MW-13, and MW-17 through MW-22.

• Collected groundwater samples from irrigation wells at seven properties.

Analytical data for well MW-10 exhibited anomalous results; therefore, an additional sample was collected from that well on March 22.

2.1 Groundwater and Stormwater Pond Elevations

On March 6, 2019, the water level was measured at each monitoring well location. Groundwater levels were measured to the nearest 0.01 foot using an electronic oil-water interface probe. Stormwater pond elevations are measured using a staff gauge permanently installed in the pond. Groundwater elevation and stormwater pond surface elevation data are listed in Table 3. The groundwater elevations measured on March 6, 2019 are shown in Table 3 and on Figure 3. Copies of field data sheets are included in Appendix A. Historical groundwater and stormwater retention pond elevations for the period August 2013 through March 2019 are tabulated in Appendix B. During the first quarter 2019 monitoring event, groundwater levels at the Site ranged between 20.22 and 30.35 feet bgs (equivalent to 1,332.68 and 1,324.23, respectively, feet above mean sea level [MSL]). Groundwater levels increased an average of 1.09 feet relative to the fourth quarter 2018 groundwater monitoring event conducted in December 2018. The elevation of the stormwater pond surface was 1344.50 feet MSL in March 2019; for comparison, the stormwater pond surface elevations from the last three quarterly monitoring events in 2018 ranged from 1343.50 to 1344.00 feet MSL. As shown on Figure 3, the groundwater elevations recorded during the first quarter 2019 event exhibited a pattern similar to previous monitoring events at the Site. That is, groundwater elevations were highest in the vicinity of the stormwater retention pond and decreased with distance from the pond. The observed pattern is likely the result of localized groundwater recharge from the stormwater retention pond. The localized recharge results in the radial flow of groundwater away from the pond. However, with increasing distance from the pond, groundwater exhibits a more easterly flow component and a flatter gradient, consistent with regional patterns (O’Connor et al., 1982).

2.2 SPH Occurrence

With the exception of the irrigation well at 2006 N Colt Court, SPH have not been observed at the Site. Consistent with the KDHE-approved Proposed SPH Removal Modification Plan, a SPH skimmer was installed in the irrigation well at 2006 N Colt Court on February 9, 2015. Gauging and SPH skimmer operations and maintenance (O&M) events were performed monthly from February 2015 through April 2016. Consistent with the proposed monitoring program modifications presented in the Revised Fourth Quarter 2015 Groundwater Monitoring Report (Apex, 2016b) and subsequent KDHE approval, SPH skimmer O&M are performed quarterly, concurrent with groundwater monitoring events. The irrigation well at 2006 N Colt Court was gauged for the presence of SPH and to measure depth to water on March 7, 2019. SPH were not detected during the gauging event. Accordingly, SPH removal activities were not necessary and a groundwater sample was collected from the irrigation well during the monitoring event. The SPH data shown in Table 4, and the historical data listed in Appendix B show that SPH were last observed in the passive skimmer in March 2015 and have not been observed in the well since that time. SPH have not been observed in any monitoring or pilot test wells at the Site, including well MW-20 (located approximately 15 feet from the release location) and MW-1 (located 30 feet from the irrigation well at 2006 N Colt Court). 2.3 Groundwater Sampling

Monitoring Wells. On March 6 through 8, a bladder pump was used to purge groundwater and collect groundwater samples from monitoring wells MW-1 through MW-4, MW-6, MW-8 through MW-11, MW-13, and MW-17 through MW-22 using low-flow sampling techniques. Prior to sampling, each well was purged while water quality parameters (pH, temperature, specific conductance, dissolved oxygen, and oxidation-reduction potential [ORP]) were recorded (Table 5). Analytical data for well MW-10 exhibited anomalous results; therefore, an additional sample was collected from that well on March 22. Irrigation Wells. Groundwater samples were collected from irrigation wells using disposable bailers. The samples from irrigation wells were collected by carefully lowering the bailer to approximately 30 feet below first encountered water (within the approximate screen interval) and retrieving the bailer. Samples were collected from eight irrigation wells (2001 N Colt Court, HOA-1, 2005 N Colt Court, 2006 N Colt Court, 2007 N Colt Court, 2019 N Ruger Circle, 2020 N Ruger Circle, and 2007 N Mountain Ct).

First Quarter 2019 Groundwater Monitoring Report Page 8 Quail Crossing Neighborhood – Andover, Kansas May 7, 2019 1641-16

2.4 Groundwater Analytical Program

Groundwater samples collected during the March 6 through 8 and March 22 events were submitted to TestAmerica in Nashville, Tennessee, a Kansas-accredited analytical laboratory, for the following analyses: low-range hydrocarbons (LRH; carbon range ≥C5 to <C9) by Method KS LRH; middle-range hydrocarbons (MRH; carbon range ≥C9 to <C19) by Method KS MRH/HRH; and volatile organic compounds (VOCs) by EPA Method 8260C. The LRH and MRH analyses are consistent with KDHE Policy #BER-041 Total Petroleum Hydrocarbons (TPH) and Light Non-Aqueous Phase Liquid (LNAPL) Characterization, Remediation and Management (September 2015). 2.5 Monitoring Well Results

Table 6 presents dissolved-phase petroleum hydrocarbon constituent data for groundwater samples collected from monitoring wells between August 2013 and March 2019. Figures 4 and 5 present analytical data for the first quarter 2019 monitoring event. Copies of the laboratory reports and a quality assurance/quality control (QA/QC) results summary are included in Appendix C. The monitoring and pilot test well groundwater data are discussed below. Groundwater monitoring conducted since 2013 supports that the extent of dissolved-phase hydrocarbons exceeding KDHE Tier 2 risk-based screening values (RBSVs) is stable to decreasing. The approximate extent of groundwater with concentrations of dissolved-phase LRH, MRH, benzene, and naphthalene are shown on Figures 6 through 9, respectively. Petroleum constituents were not detected or were detected at concentrations lower than KDHE Tier 2 RBSVs in nine of the sixteen monitoring wells sampled this quarter (MW-2, MW-4, MW-6, MW-8, MW-9, MW-10 (3/22/2019), MW-11, MW-13, and MW-21). Petroleum constituents were detected at concentrations above KDHE Tier 2 RBSVs in seven of the sixteen monitoring wells sampled (MW-1, MW-3, MW-17, MW-18, MW-19, MW-20 and MW-22; those wells are within the NuStar pipeline easement boundary). As previously noted, analytical data from well MW-10 sampled on March 6 exhibited anomalous results, and as such, this well was resampled on March 22, 2019. Analysis of the March 22 groundwater sample indicated that petroleum constituents were not detected above the laboratory reporting limits, which is consistent with historical data for this well. Results from the March 6 and March 22 sampling events are presented in Table 6 and Figures 4 and 5.

The approximate extent of dissolved-phase constituents in groundwater above KDHE Tier 2 RBSVs is shown on Figures 6 through 9 (for well MW-10, the March 22 data were used for contouring). As represented by benzene, the approximate extent of dissolved-phase constituents in groundwater above the corresponding KDHE Tier 2 RBSV decreased by approximately 90 percent between August/September 2013 and December 2017; and that approximate extent has been stable since December 2017.

2.6 Analytical Results – Irrigation Wells

As shown in Table 2, the KDHE-approved groundwater monitoring program includes the collection of samples from seven irrigation wells during the first quarter. Irrigation well analytical data for the first quarter 2019 monitoring event are listed in Table 7 and shown on Figures 4 and 5. The construction of Site monitoring wells (shorter screen and sand pack intervals) is conducive to the collection of groundwater samples that are representative of dissolved-phase conditions at the Site. In contrast, the irrigation wells were not constructed for the purpose of environmental investigation (i.e. long screen and gravel pack intervals). As a result, analytical results from irrigation wells should be considered qualitative, at best. Copies of the laboratory reports are included in Appendix C. The irrigation well groundwater data are discussed below:

• During the first quarter 2019 groundwater monitoring event, dissolved-phase hydrocarbon constituents were not detected or were present at concentrations less than the corresponding KDHE Tier 2 RBSV in six of seven irrigation wells sampled (2001 N Colt Court, HOA-1, 2005 N Colt Ct, 2007 N Colt Court, 2019 N Ruger Circle, and 2020 N Ruger Circle).

• As discussed in Section 2.2, SPH had been observed in the irrigation well at 2006 N Colt Court until February 2015. SPH have not been observed since that time and were not observed in March 2019; therefore, a water sample was collected for analysis. As shown in Table 7, the sample collected in March 2019 contained dissolved-phase concentrations of LRH, MRH, benzene, 1,2,4-trimethylbenzene, and naphthalene above the corresponding KDHE Tier 2 RBSVs. Concentrations of dissolved-phase constituents in the sample were on the lower end of the historical range observed from that well.

o This irrigation well was deactivated in 2012 and the irrigation system was reconfigured to receive municipal water.

2.7 Data Quality Evaluation

Field duplicate samples were collected from monitoring wells MW-2, MW-13, and the irrigation well at 2007 N Colt Ct. The relative percent difference values were within the 30% control limit. A quality assurance/quality control (QA/QC) results summary is provided in Appendix C; the QA/QC review indicates that the QA objectives have been met and the data are of sufficient quality for use in this project.

Notes:1. GRO = Gasoline-range organics analyzed by U.S. Environmental Protection Agency (EPA) Method 8015D. During the March 2016 event KDHE analyzed GRO by 8260.2. LRH = Low-range hydrocarbons by KDHE Method KS LRH. LRH was first analyzed during the March 2016 event by EPA Method 8015. KDHE analyzed LRH in March 2016 by EPA Method 8260. 3. MRH = Middle-range hydrocarbons by KDHE Method KS MRH/HRH. MRH was first analyzed during the March 2016 event by EPA Method 8015M. 4. Volatile organic compounds by EPA Method 8260 (low level VOCs). 5. mg/L (ppm) = Milligrams per liter (parts per million).6. Bold indicates detected concentration above the KDHE screening value.7. < = Not detected above the method reporting limit (MRL).8. -- = Not analyzed. 9. j = Relative percent difference was > 30%.

11. NE = A KDHE Tier 2 Risk Based Screening Value has not been established. 12. KDHE Tier 2 Screening Values from the Risk-Based Standards for Kansas, 5th Edition , October 2010. 13. Well locations are shown on Figure 2. 14. NS = No sample collected. 15. KDHE Split = Sample at time of collection was split with KDHE and analyzed independently.16. KDHE 2005 N Colt Ct U = This sample was collected with a bailer from first encountered water. 17. Duplicate = Field duplicate sample.18. J = Result is estimated. 19. H = Results for this analyte were obtained outside of the method holding time due to lab error. 20. B = Analyte was found in the method blank and sample. Concentration may be biased high.21. UJ = The not detected value is estimated based on data quality.

10. The samples collected from 12 irrigation wells (2001 N Colt Court, 2002 N Colt Court, 2004 N Colt Court, 2005 N Colt Court, 2007 N Colt Court, 2019 N Ruger Circle, 2020 N Ruger Circle, 2032 N Ruger Circle, 2007 N Mountain Court, 2009 N Mountain Court, 1211 W Quail Crossing Court, and 1009 W Mountain) during the week of June 20, 2016 were delayed due to a FedEx shipping error; those samples were received by the analytical lab out of hold time and were not analyzed. The wells were resampled on July 22, 2016.

2.1 Data Qualifiers

Any data that is found to have possible bias or error were qualified and flagged. The flags used in the data table are below.

J Result is an estimated value.

3.0 Analytical Methods

Chemical analyses of water samples consisted of the following:

• Low-range hydrocarbons (LRH) by KDHE Method KS LRH;

• Mid-range hydrocarbons (MRH) by KDHE Method KS MRH/HRH; and

• 1,2,4-Trimethylbenzene, 1,2-dichloroethane, 1,3,5-trimethylbenzene, 2-butanone, cyclohexane, isopropylbenzene, methylcyclohexane, BTEX (benzene, toluene, ethylbenzene, total xylenes), naphthalene, n-butylbenzene, and n-propylbenzene by U.S. Environmental Protection Agency (EPA) SW-846 test method 8260C.

4.0 Quality Assurance Objectives and Review

The general QA objectives for this project were to develop and implement procedures for obtaining, evaluating, and confirming the usability of data of a specified quality for monitoring groundwater quality trends at the Site. To collect such information, analytical data must have an appropriate degree of accuracy and reproducibility, samples collected must be representative of actual field conditions, and samples must be collected and analyzed using unbroken chain-of-custody procedures. Reporting limits and analytical results were compared to action levels for each parameter in the matrix of concern. Precision, accuracy, representativeness, completeness, and comparability parameters used to indicate data quality are defined as follows.

4.1 Holding Times and Sample Receipt

Holding times are the length of time a sample can be stored after collection and prior to analysis or extraction without significantly affecting the analytical results. Holding times vary by analyte, sample matrix, and analytical methodology. The groundwater samples included in this QA/QC review were analyzed within the

Appendix C — Laboratory Analytical Reports and Quality Assurance/Quality Control Results Summary

method recommended holding time. Below is a table outlining sample holding times based on sampling preservation and matrix.

Method Matrix Analyte Preservative Hold Time

EPA 8260C Water Volatile Organic Compounds Hydrochloric Acid (HCl) to pH<2; No headspace; glass VOA container 14 days

KS LRH Water Low-Range Hydrocarbons Hydrochloric Acid (HCl) to pH<2; No headspace; glass VOA container 14 days

KS MRH/HRH Water Mid-Range Hydrocarbons Hydrochloric Acid (HCl) to pH<2;

glass container 14 days

Samples were received on ice by the analytical laboratory. Sampling containers arrived intact and unbroken to the laboratory. Groundwater samples to be analyzed for VOCs were received without headspace in VOA sampling containers. Chain of custody documents were appropriately relinquished by the Apex Companies sampler and received by TestAmerica. They were filled out with the correct sample ID, sampling date, sampling time, and analyses requested. There were no discrepancies found between container labels and the chain of custodies received. 4.2 Reporting Limits

Reporting limits are the lowest concentration an instrument is capable of accurately detecting an analyte. They are determined by the laboratory and are based on instrumentation capabilities, the matrix of field samples, sample preparation procedures and suggested reporting limits by the EPA or the KDHE. In some cases, the reporting limits may be raised due to high concentrations of analytes or matrix interferences. Reporting limits were consistent with industry standards and were below KDHE Tier 2 Risk-Based Screening Values, with the exception of 1,2-dichloroethane for well MW-20. 4.3 Method Blanks

A method – or laboratory – blank is a quality control sample prepared by the laboratory from an analyte-free matrix and analyzed in an analytical batch along with environmental and other QC samples. It is used to assess laboratory contamination or background interferences. Analytical batch method blank samples were not detected for target analytes. 4.4 Trip Blanks

A trip blank is an analyte-free matrix that is taken from the laboratory to the sampling site and transported back to the laboratory unopened. Trip blanks assess contamination introduced during shipping and field handling activities. Two trip blanks were analyzed for the sampling event for VOCs by EPA Method 8260C and no compounds were detected.

4.5 Accuracy

Accuracy compares the accepted reference concentration of an analyte to the concentration determined analytically. Accuracy is measured as a percent recovery. This recovery must be within a certain range – or control limit – for the data in an analytical batch to be considered acceptable. The analytical laboratory provides quality control samples and surrogates to help determine the accuracy and acceptability of the data reported. These quality control samples and surrogates are discussed below. 4.5.1 Laboratory Control Samples

Laboratory control samples (LCS) and laboratory control sample duplicates (LCSD) were analyzed by the laboratory to assess the accuracy of the analytical methods. One set of LCS and LCSDs were analyzed per analytical batch. The LCS and LCSDs are prepared from an analyte-free matrix that is spiked with known levels of compounds of concern. The concentrations are measured and compared to the known spiked levels; expressed as a percent recovery. The benzene and cyclohexane recoveries were above the upper control limit for analytical batch 583625; however, the associated sample (collected from well MW-10) was not detected for benzene or cyclohexane. Results are acceptable for use and not flagged. 4.5.2 Matrix Samples

A matrix spike QC sample is used to assess the performance of the analytical method by determining potential matrix interferences. Matrix spike (MS) and matrix spike duplicate (MSD) analyses are performed on one environmental sample per analytical batch. A matrix spike sample uses an environmental sample that is spiked with known concentrations of analytes of interest. The matrix spike is then prepared and analyzed with the same analytical procedures as environmental samples in the analytical batch. The resulting concentration of the matrix spike is then compared to the known – or true – values added to the non-spiked environmental sample concentration. This comparison is expressed as a percent recovery. The recovery of MSD analytes for batch 580165 were below the lower control limits for ethylbenzene, toluene, 1,2,4-trimethylbenzene, and total xylenes. These analytes are present in the original sample (monitoring well MW-20) at concentrations greater than four times the matrix spike concentration; therefore, control limits are not applicable. Additionally, cyclohexane was recovered below the lower control limit for the MSD; however, the MS recovery for cyclohexane was within control limits. The well MW-20 results for cyclohexane is estimated and ‘J’ flagged due to variability in the recovery of this analyte.

Appendix C — Laboratory Analytical Reports and Quality Assurance/Quality Control Results Summary

First Quarter 2019 Groundwater Monitoring Report Page C-5 Quail Crossing Neighborhood – Andover, Kansas May 7, 2019 1641-16

4.5.3 Surrogates

Surrogates are organic compounds that are similar in chemical composition to the analytes of interest but are not likely to be found in the environment. They are spiked at a known concentration into environmental and batch QC samples prior to sample preparation and analysis. Surrogate recoveries for environmental samples are used to evaluate matrix interference, sample preparation efficiency, and analysis performance on a sample-specific basis. Surrogate recoveries were within control limits. 4.6 Precision

Precision is measured by how close values of duplicate analyses are to each other. These duplicate analyses are prepared from separate aliquots of the same sample and are analyzed at the same (or similar) time. Precision in the field ensures that samples taken are representative of field concentrations; this is demonstrated by field duplicates. Analytical precision is the ability of the laboratory to reproduce results that are similar to each other; this is measured through the duplicate analysis of environmental and batch QC samples. Precision is estimated by the relative percent difference (RPD) between the original analysis and the duplicate analysis. 4.6.1 Laboratory Control Sample Duplicates

The analytical batch LCS concentration of an analyte is compared to the LCSD concentration of the same analyte. The RPD is calculated from these two concentrations; which must be below a certain percentage to be considered acceptable. RPD values for analytical batch LCS/LCSDs were within control limits. 4.6.2 Matrix Spike Duplicates

Similar to the LCS/LCSD, the analytical batch MS/MSD analyte concentrations are also compared to each other and expressed as an RPD. The RPD cyclohexane and methylcyclohexane from analytical batch 580165 exceeded the control limit. The source of the MS and MSD for batch 580165 was collected from well MW-20. Due to the RPD exceedance, the result for cyclohexane from well MW-20 is estimated and ‘J’ flagged. The methylcyclohexane result is considered acceptable for use since methylcyclohexane was not detected in the sample collected from well MW-20. 4.6.3 Field Duplicate

A field duplicate is a second field sample collected from a selected sample location. Field duplicate samples serve as a check on laboratory precision and sampling quality, as well as potential variability of the sample matrix. The field duplicate is analyzed and compared to the original sample to assess precision. This

Appendix C — Laboratory Analytical Reports and Quality Assurance/Quality Control Results Summary

First Quarter 2019 Groundwater Monitoring Report Page C-6 Quail Crossing Neighborhood – Andover, Kansas May 7, 2019 1641-16

comparison can be expressed by the RPD between the original and duplicate samples. Only detections greater than the reporting limit are controlled and used for quality control purposes. Field duplicate samples were collected from monitoring wells MW-2, MW-13, and the irrigation well at 2007 N Colt Ct. RPD values were within the 30% control limit.

5.0 Conclusion

In conclusion, the QA objectives have been met and the data are of sufficient quality for use in this project.
