    Environmental Resources June 28, 2012 Management Mr. Mostafa Mehran 15810 Park Ten Place Senior Engineer, Hazardous Waste Division Suite 300 Houston, Texas 77084-5140 Arkansas Department of Environmental Quality (281) 600-1000 5301 Northshore Drive (281) 600-1001 (fax) North Little Rock, Arkansas 72118 Project No. 0159348 Subject: 2011/2012 Annual Ground Water Monitoring Report Whirlpool Corporation, Fort Smith, Arkansas Dear Mr. Mehran: Environmental Resources Management (ERM) is pleased to provide this 2011/2012 Annual Ground Water Monitoring Report for the Whirlpool Fort Smith site. For more than ten years, Whirlpool has implemented a regular sampling program to monitor the concentrations and distribution of affected ground water associated with a historical release of trichloroethylene (TCE) at the Whirlpool Fort Smith facility. Based on investigations conducted between 1999 and 2006, TCE and associated degradation products (primarily cis-1,2- dichloroethene) are present in shallow ground water at the Whirlpool facility and have migrated off-site into a residential area north of the facility. In an initial effort to remediate the off-site portion of the ground water plume, Whirlpool has conducted an Interim Measure (IM). This report incorporates sampling results from monitoring conducted to evaluate the effectiveness of the IM and semiannual sampling conducted between Fall 2011 and Spring 2012. Background As discussed in earlier IM Status Reports, the IM was conducted as a two- phased program. The initial phase included two In-situ chemical oxidation (ISCO) treatment events (conducted in April 2009 and July 2009) to evaluate the effectiveness of ISCO at treating the core of the off-site plume. The second phase was conducted between July 2010 and March 2011, and consisted of continued ground water monitoring and the pilot operation of a ground water pumping system. The objective of the pumping system was to test the ability to induce gradients and pull oxidant through the plume to treat the core of the plume. Observations through March 2011 indicated the in situ permanganate treatments applied in 2009 had reduced concentrations of 1,1,2- trichloroethylene (TCE) in the immediate vicinity of the treatment wells. However, the pilot ground water pumping operations did not create sufficient gradients across the core of the plume to pull the permanganate to areas beyond the treatment wells.

    June 28, 2012 Mr. Mostafa Mehran Page 2 Operational difficulties associated with the ground water pumping system and limited access to certain properties indicate that using a pumping system as part of a longer-term component of the IM program is not feasible. Whirlpool has continued the semi-annual sampling and performance monitoring to further assess the changes in ground water conditions after completion of the IM. Scope of Work The Fall 2011 semiannual ground water monitoring event for the Whirlpool Fort Smith facility was conducted October 24 through 27. The Spring 2012 semiannual event was conducted April 16 through 19. The scope of work for each semiannual event included: • Gauging of water levels in 66 wells in the Fall and 64 wells in the Spring; • Collection of ground water samples for analysis of VOCs, potassium, chloride, nitrate, and sulfate from 65 monitor wells during the Fall event and 39 monitor wells during the Spring event (during the Fall sampling event, several wells were added to the sampling program to provide more information on the nature of the ground water plume in areas that have not been regularly sampled in the past few years) ; and • Collection of natural attenuation geochemical data including pH, specific conductivity (SC), temperature, dissolved oxygen (DO) Oxidation-reduction potential (ORP) and iron from 65 monitor wells during the Fall event and 39 monitor wells during the Spring event. Sampling and Analyses Methods During each semiannual sampling event, water levels in each well were gauged prior to sampling. Water level measurements are provided in Table 1 (Attachment 1). Following gauging activities, low-flow ground water sampling was performed using a peristaltic pump and dedicated polyethylene tubing. The tubing intake was placed at a depth in each well corresponding to the approximate middle of the Transmissive Zone. During low-flow purging, the wells were pumped at a rate generally less than 0.1 L/min in order to limit drawdown in the wells. Flow rate was checked using a stopwatch and Pyrex® graduated measuring cup. The drawdown and flow rate were monitored continuously during sampling, except in small diameter wells, where only flow rate was monitored. Due to very slow recovery rates, low-flow sampling techniques were not followed at eight wells during the Fall 2011 sampling event (MW-50, MW-55, MW-56, MW-57, MW-60, MW-61, MW-62, and MW-63). These wells were purged dry once and then allowed to recover prior to sampling. Low-flow sampling techniques were successfully used on all 39 wells during the Spring 2012 sampling event. Water quality parameters were monitored using a Troll 9000 water quality probe and flow- thru cell. Readings were recorded approximately every three minutes until parameters stabilized over three successive readings. Stabilization parameters included:

    June 28, 2012 Mr. Mostafa Mehran Page 3 • pH within 0.1 standard units; • Temp + 1° C; • SC + 3%; • Turbidity + 10%; • DO + 10%; and • ORP + 10 mV. The parameters met the stabilization criteria within 1 hour in all wells that were sampled using low-flow techniques. Purge water generated during sampling was placed in containers for proper disposal by Whirlpool. Ground water samples were collected in laboratory-supplied containers. Samples for VOC analysis were collected in three 40-ml glass vials preserved with hydrochloric acid.. Samples collected for sulfate and chloride analysis were collected in neat 750 ml plastic jars. Samples for potassium analysis were collected in 100 ml plastic jars and preserved with nitric acid. Samples for nitrate analysis were collected in 150 ml plastic jars preserved with sulfuric acid. Samples for iron analysis were collected in a Pyrex® beaker and tested in the field using a colorimeter and Hach Accuvac Ampules. Blind duplicate samples, field blank samples, and trip blank samples were collected during each of the semiannual events. All samples for VOC analysis were labeled, stored on ice, and shipped to Test America in Houston, Texas for analyses by SW-846 Method 8260B for trichloroethylene (TCE), related chlorinated solvents, and degradation products that have been identified in previous sampling events. Samples for analysis of natural attenuation parameters (potassium, chloride, nitrate and sulfate) were labeled, stored on ice in an on-site cooler, and picked up by Data Testing, Inc. in Fort Smith, Arkansas for analyses by EPA water/wastewater methods. Samples for ferrous iron analysis were analyzed in the field by Hach DR820 colorimeter Accuvac Ampule method 8146. Chain of custody procedures were established and followed from the time of sample collection until the analyses were complete. Ground Water Flow Evaluation Based on an evaluation of potentiometric surface maps over the last five years, it appears that there are two distinct ground water flow regimes at the Fort Smith site. As illustrated by the potentiometric surface maps for Fall 2011 and Spring 2012 (Figures 1 and 2 [Attachment 2]), there is a broad area generally east of Ferguson Street and north of Ingersol Avenue where ground water flows to the northeast. This area is referred to as the Northern Flow Regime. A Southern Flow Regime, covering the majority of the Whirlpool Facility and extends south of Ingersol Avenue, flows southwestward. The flow regimes are separated by a ground water divide that is consistently present along a zone roughly coincident with the Whirlpool North Parking Lot (Figure 3). Over the past few years, the ground water divide has become less well defined and more broad than in the past, forming a fairly flat area where there is very little flow.

    June 28, 2012 Mr. Mostafa Mehran Page 4 In the Northern Flow Regime, ground water flow is consistently toward the northeast with a gradient north of Jacobs St. that, for this reporting period, ranged from 0.014 to 0.0148 ft/ft from Fall to Spring. Ground water flow gradients in the Southern Flow Regime are generally much lower, ranging from 0.00057 to 0.00183 ft/ft, and also exhibit minor seasonal fluctuations. The prevailing flow direction historically exhibits seasonal shifts of as much as 90 degrees. Ground water appears to flow to the south/southwest during Fall (Figure 1), and to the southeast during Spring (Figure 2). Discussion of Sampling Results Analytical data from the Fall 2011 and Spring 2012 sampling activities are summarized in Tables 2 and 3. A total of 21 VOCs were reported in samples from on-site source area monitor wells. In most cases only TCE and cis, 1-2 DCE were detected in off-site wells. TCE and cis, 1-2 DCE concentration maps illustrating the Fall 2011 and Spring 2012 data are provided as Figures 4 and 5. To facilitate a review of the data over time, the monitor wells have been placed into several groups based on proximity to the source area; two groups of wells have been defined for the Northern Flow Regime and three groups of wells in the Southern Flow Regime. The following groupings are illustrated and identified on Figure 3, and graphs showing concentrations over time for key wells in each group are provided in Attachment 2. Northern Flow Regime: North Boundary Area Wells (Figure 6 [Attachment2]) Off-Site Area Wells (Figure 7 [Attachment 2]) Southern Flow Regime: Source Area Wells (Figure 8 [Attachment 2]) Pilot Study Area Wells (Figure 9 [Attachment 2]) Fringe Area Wells (Figure 10 [Attachment 2]) North Boundary Area Wells The North Boundary Area includes wells along Ingersoll Avenue (Figure 3). All North Boundary Area Wells are located on Whirlpool Property or on Ingersoll Avenue rights-of- way. Concentrations in most of the North Boundary Area wells appear stable with minor seasonal fluctuations (Figure 6). TCE and cis-1,2-DCE concentrations in MW-35 decreased significantly following the ISCO treatment events conducted in 2009. For example, TCE concentrations in MW-35 (situated at the southern end of the area where the ISCO treatment was applied as part of the IM) were typically near or slightly above 1 mg/L prior to treatment, but decreased to about 0.25 mg/L since the in situ treatment. However, TCE at MW-33 (located just south of Ingersol) has remained stable with TCE concentrations of 1 to 1.3 mg/L prior to and after treatment.

    June 28, 2012 Mr. Mostafa Mehran Page 5 Two of the common daughter products (1,1-Dichloroethene [1,1-DCE] or vinyl chloride) have generally been reported at very low levels or as Not Detected in the North Boundary Area Wells. Off-Site Area Wells The Off-Site Area includes all the wells installed at off-site properties to the north and northeast of the North Boundary Area and includes the area that was the target of the IM activities. (Figure 3). TCE concentrations in the Off-Site Area in 2012 continue to exhibit generally stable trends, while cis1,2-DCE is generally decreasing. Sample results from MW-41, located in the center of the ISCO treatment area, illustrate response to the ISCO Treatment. Prior to ISCO treatment, the TCE concentrations ranged from about 1 mg/L to 0.8 mg/L. Since the ISCO treatment events in 2009, TCE concentrations have reduced. With the exception of May and November 2010, TCE concentrations are below 0.7 mg/L. (Concentrations at MW-42 and MW-43 have not been measured over the past two years because these wells were damaged and temporarily sealed in place pending formal plugging and abandonment..) Samples from wells located at the perimeter of the Off-Site Area continue to be reported as Not Detected or estimated (“J-flagged”). These include MW-50, MW-60, MW-61, MW-62, MW-66, and MW-67. Exceptions include MW-46R and MW-63 (located east beyond the influence of the ISCO treatment area along Jacobs Avenue) where concentrations have generally remained stable. Discussion of Southern Flow Regime Analytical Results Source Area Wells The Source Area includes wells immediately adjacent to the northwest corner of the Whirlpool Factory Building and located west of the former degreaser building, the suspected source of TCE at the site (Figure 3). The highest TCE concentrations have historically been reported at MW-25 (157 mg/l in September 2002). Other Source Area Wells typically range up to about 20 mg/L. The concentration of daughter products (cis 1,2-DCE, 1,1-DCE, and vinyl chloride) are also highest in the source area wells. During the first several years following the permanganate injection pilot test, cis-1,2-DCE and vinyl chloride concentrations at MW-25 increased slightly relative to TCE concentrations. This trend is consistent with reductive dechlorination in an anaerobic environment. Since 2010, the concentrations of both TCE and cis-1,2-DCE appear to have stabilized indicating the rate of reductive dechlorination may have decreased. Pilot Study Area Wells The Pilot Study Area Wells includes wells that are located northeast of the Source Area Wells (Figure 3) in the zone of influence of an in-situ chemical oxidation (ISCO) Pilot Study Texas Registered Engineering Firm F-2393 G:\2012\0159348\17766H ltrpt.doc

    June 28, 2012 Mr. Mostafa Mehran Page 6 conducted in 2001. Effects of the ISCO pilot study included a sharp decrease in TCE followed by rebound as affected water moved back into the area. Observed changes also included production of daughter products evidenced by an increase in cis-1,2-DCE concentrations followed by an increase in vinyl chloride concentrations. More recently, concentrations in the Pilot Study Area Wells appear to be generally stable to slightly increasing; the one exception being MW-37 (Figure 9). , TCE has increased in MW-37 from less than 1 mg/L to over 50 mg/L, but in the past three years the concentration appears to have stabilized between about 30 mg/L and 55 mg/L. It appears that affected ground water not influenced by the pilot study has migrated into the pilot study area resulting in the anomalous increase in concentrations at MW-37. Fringe Area Wells The Fringe Area Wells are located on both the Northeast and Southwest sides of the Source Area. Concentration trends in Fringe Area Wells appear to be generally stable (Figure 9). Data Usability Based on data, a limited quality review conducted in general accordance with the United States Environmental Protection Agency’s (EPA’s) National Functional Guidelines for Organic Data Review (EPA540/R-99/008, October 1999). The laboratory data were determined to be generally usable for the purpose of this study. Data validation reports are provided in Attachment 3. Evaluation of Natural Attenuation Data Observed trends in the ground water data for many source area wells are consistent with changes associated with active reductive dechlorination (Table 2 and 3 [Attachment 1]). As described above, data collected from many of the wells north and south of the ground water divide are decreasing or stable, indicating that the ground water plume is generally stable or shrinking. Additional evidence of active reductive dechlorination processes in the source area include: • Elevated chloride concentrations in areas not impacted by the pilot study (ITMW-17, ITMW-19, ITMW-21, MW-23, MW-24, and MW-25; and • Depleted sulfate concentrations in the vicinity of the on-site and off-site TCE plumes (ITMW-17, ITMW-19, ITMW-21, MW-25, and MW-30; and MW-40, MW-46, MW-70, MW- 71, and IW-74, respectively). These data indicate that natural attenuation processes are active in the Source Area. Outside of these areas where the aquifer is more consistently aerobic, there does not appear to be evidence of significant degradation of the TCE or cis-1,2-DCE by natural attenuation.

    Environmental Resources June 28, 2012 Management Mr. Mostafa Mehran Page 7 Summary A review of water level data from on-site andoff-site wells continue to indicate there are two ground waterflow regimes across the Site. The Northern Flow Regime and Southern Flow Regime are separated by a ground waterdivide that is generally situated in a zone south of Ingersol Avenue. The divide appears to be more broad thanin the past, forminga flat area wherethere is verylittle flow. : In the Northern Flow Regime,wells that are in and directly adjacent to the area wherethe ISCO treatment IM was conducted in 2009 exhibit lower concentrations than priorto the IM. Some TCE concentrations are reboundingslightly (e.g., MW-41). Other wells that are outside the influence of the IM appear to have stable orslightly decreasing trends. In the Southern Flow Regime, the ground water plumealso appearsto be stable, however, concentrations in the Source Area continue to exhibit seasonal fluctuations and remain at historically high levels (in the range of 15 to 30 mg/L and as high as 120 mg/L at MW-25). The overall affect of the off-site ISCO treatment appears to have reduced concentrations near the centerof the IM area by abouthalf. However, dueto the very low ground watergradients in the area, TCEin the core of the off-site part of the plume remain from 0.5 to 1 mg/L. Weappreciate the opportunity to continue to assist Whirlpool with this importantproject.

    Data Validation Report Attachment 3 Whirlpool Corporation Fort Smith, Arkansas Introduction Environmental Resources Management (ERM) reviewed the following laboratory sample delivery groups (SDG) from TestAmerica Laboratories, Inc. of Houston, Texas for ground water samples collected at the Whirlpool Corporation facility in Fort Smith, Arkansas: • 600-45228-1 – October 24 - 27, 2011, and • 600-53847-1 – April 17 – 19, 2012 Analysis requested was limited to SW-846 8260B – Volatile Organic Compounds (VOCs) by Gas Chromatography/Mass Spectrometry (GC/MS). Data were reviewed and validated in accordance with the United States Environmental Protection Agency’s (EPA’s) National Functional Guidelines for Organic Data Review (EPA540/R- 99/008, October 1999). The following laboratory submittals were evaluated: • Sample Preservation and Holding Times, • GC/MS Instrument Performance Check, • Initial Calibration, • Continuing Calibration, • Blanks, • System Monitoring Compounds, • Internal Standards, • Laboratory Control Samples, • Matrix Spike/Matrix Spike Duplicates, • Field Precision, and • Overall Assessment of Data. Data Review / Validation Results Analytical Results One hundred and five (105) ground water samples, six blind ground water field duplicates, five field blanks, and four trip blanks were submitted to the laboratory and analyzed for VOCs. In addition, ground water samples were collected at six locations (MW-25, ITMW-17, ITMW-16, ITMW-10, MW-26, and ITMW-14) and submitted to the laboratory for the matrix spike/matrix spike duplicate (MS/MSD) analysis. The following table lists the sample identifications by SDG. A3-1 G:\2012\0159348\17766H(Att3).docx

Ground water analytical results are reported in ug/L. Not Detected results are reported as less than the value of the practical quantitation limit (PQL). Preservation and Holding Times The samples were evaluated for agreement with the chain-of-custody. The samples were received by the laboratory in the appropriate containers and in good condition. Sample receipt temperatures of 4.9, 4.3, 1.1, and 1.3 degrees Celsius were within the acceptance criteria of 4 ± 2 degrees Celsius for SDGs 600-53847-1 and 600-45228-1, respectively. Samples IW-75 (600-53847- 1 and 600-45228-1), IW-79, IW-74, IW-73, IW-76 (600-53847-1 and 600-45228-1), and IW-80 were preserved with 5 grams of lab-grade ascorbic acid for residual permanganate quenching methods; however, they were not preserved in the field with HCl to bring the pH below 2. Because the samples were received within the temperature acceptance criteria and were analyzed within 7 days, results were not qualified. The remaining samples were preserved in the field as specified by the method and were prepared and analyzed within holding times. GC/MS Instrument Performance Check GC/MS instrument performance checks are performed to ensure mass resolution, identification, and sensitivity. The appropriate compound, bromofluorobenzene (BFB) for volatile analysis, was used for instrument tuning. GC/MS tunes were performed at the appropriate frequency (once every 12 hours). BFB ion abundance met criteria specified by the method. No analytical data were qualified based on the results of the GC/MS instrument performance check. Initial Calibration Initial calibration demonstrates that the instrument is capable of acceptable performance at the start of an analytical run and producing a linear calibration curve. Six standards (5, 10, 20, 50, 100, and 200) were used for the initial calibration. The initial calibration relative response factors (RRFs) were greater than 0.05 for all VOCs and system monitoring compounds. The A3-2 G:\2012\0159348\17766H(Att3).docx

    percent relative standard deviation (%RSD) was less than 30% for all relative VOCs and system monitoring compounds. No analytical data were qualified based on the results of the initial calibration. Continuing Calibration Continuing calibration establishes the 12-hour relative response factors on which quantitations are based and checks satisfactory instrument performance on a day-to-day basis. The continuing calibration RRFs were greater than 0.05 for all VOCs and system monitoring compounds. The percent difference (%D) between the initial calibration and continuing calibration RRFs were less than 30% for all VOCs and system monitoring compounds, except as detailed below. Constituent results associated with the CCV exceedance were qualified as estimated (J or UJ).

    System Monitoring Compounds System monitoring compounds are added to all samples prior to purging to evaluate the laboratory performance on individual samples. Four volatile surrogates (dibromofluoromethane, 1,2-dichloroethane-d4, toluene-d8, and bromofluorobenzene) were added to each sample. Percent recoveries (%R) for all volatile surrogates in all samples were within the method acceptance limits of 70%-130%. No analytical data were qualified based on the results of the system monitoring compounds. Internal Standards Internal standards indicate whether GC/MS sensitivity and response were stable during each analysis. Four internal standards (pentafluorobenzene, 1,4-difluorobenzene, chlorobenzene-d5, and 1,4-dichlorobenzene-d4) were added to each sample prior to volatile analysis. All internal standard area counts were within the method-required QC limits of -50% to +100% of the internal standard area counts for the associated 12-hour calibration standard. The retention times for all internal standards did not vary more than the method-specified QC limit of ±30 seconds from the retention time of the associated 12-hour calibration standard. No analytical data were qualified based on the results of the internal standards. Laboratory Control Samples The laboratory control sample (LCS) provides information on the accuracy of the analytical method and on the laboratory performance. The following table summarizes the LCS results that were outside the acceptance limits of 60% to 140% and any associated qualifications.
