Mr. Dante Rodriguez U.S. Environmental Protection Agency Region IX 75 Hawthorne Street, SFD-7-1 San Francisco, California 94105 Subject:Groundwater MonitoringReport, July throughDecember2012,Former Sola Optical U.S.A., Inc., Facility, 1500CaderLane, Petaluma, California Dear Mr. Rodriguez: This report presents the results ofgroundwater monitoringactivities conductedduring the period from July throughDecember2012at the Former Sola Optical U.S.A., Inc.,facilitylocated at 1500Cader LaneinPetaluma, California (“the Site”; Figure 1).ARCADISU.S., Inc. (ARCADIS)conducted theseactivities at the Site onbehalf ofCarl Zeiss Vision Inc.(purchaser of American Optical, Sola[formerly Sola Optical U.S.A., Inc.]). Work Performed During the Reporting Period Groundwater Monitoring Activities

ARCADISconductedsemiannualgroundwater monitoringactivities at the SiteinAugust 2012in accordance with thegroundwatermonitoring program for the Site.

OnJuly 25, 2012, ARCADISpersonnel measureddepth to groundwater in monitoring wellW-27 and former extraction wellsE-1 and E-2 (Figure 2)and collectedagroundwatersample from well W-27.The water level was not measured in f ormer extraction well E-4,becausea large vehicle
wasparked overthe well box

.Well W-27was purged using a clean, disposable polyvinylchloride (PVC) bailerprior to collection of a sample. Groundwater pH, temperature, specific conductance, and turbiditywere measuredfollowingthe purging of each well casing volume.Afterthreewell casing volumes of waterwere purged,sampleswere collected using a clean, disposable PVC bailer atthewell. Collected samples were decanted into 40

-millilitervolatile organic analysisvials (VOAs)preserved with hydrochloric acidandlabeled with the project number, well number, date, time, and analytical method

.Thelid of each VOA was thensecured with a chain

-of custody seal, and the VOAs werestored in an ice

-cooled chestandtransported under chain-of-custody protocol to the analytical laboratory. Groundwater samples were submitted to Curtis & Tompkins, Ltd.,a California

-certified laboratory, for analysis of volatile organic compounds (VOCs) by U.S.Environmental Protection AgencyMethod 8260B (usingan 8010analytelist).smr

## Groundwater Monitoring Results Depth to groundwater and calculated groundwater elevations are presented in Table 1.Table 1 also includes historical depth

-to

-water measurements and groundwater elevations collected since the groundwater extraction and treatment system was shut down on March 23, 1997.Historical groundwater elevations are presented in TableA-1(Appendix A). Table 2 presents selectanalytical results of groundwater samples collected from 1997 through the present, including the current sampling event.All historical analytical results for the Site are presented in TableA-2 (Appendix A).Thecertified laboratory analytical report and water-quality field sampling sheets are on file atARCADIS

.Finally, concentrations of 1,1-dichloroethene (1,1-DCE) and 1,1

-dichloroethane (1,1

-DCA; the only VOCs detected in groundwater at the Site inrecentmonitoring events) detected during theJulymonitoring event are presented on Figure3.
Groundwater Elevations Groundwater contours were not prepared for this sampling eventbecauseonly four wells remain and the spatial relationship of the wells istooclose to provide an accurate depictionof groundwater flow.Shallow groundwater flowat theSitehashistoricallybeentoward thesouthsouthwest, in the general direction of the Petaluma River,since environmental investigations began at the Site in 1986

. Concentrations of VOCs During the current monitoring event, onlyoneVOC (1,1

-DCA) wasdetectedin the groundwater sample collected from well W-27.
**1,1- DCA.** 1,1-DCA wasdetected in the samplescollected from well MW

-27at concentrations of 1.7micrograms per liter(μg/l)and 1.6μg/l(primary and duplicate samples) in August 2012

. Theseconcentrationsof 1,1

-DCAarebelow themaximum contaminant level (MCL)of 5μg/l. Agraph of 1,1

-DCA concentrations versus time for well W-27,presented onFigure4,illustrates an overalldecreasing trendsince October 2003

. **1,1- DCE.** 1,1-DCE wasnotdetectedabove the laboratory detection limit in the groundwater sample from W-27 duringthe reporting period. This is the first 1,1

-DCE concentration belowthe reporting limit in this well since November 2000. A graph of the 1,1

-DCE concentration versus time for W

-27 is presentedon Figure 5.As shown onFigure 5,the 1,1

-DCE concentrations have been below the MCL since April 2002. A field blank sample (W-27-FB) was also collected during the current monitoring event to demonstratethatthesampling equipmentwas not contributing any VOCs to the groundwater samples

.A laboratory

-provided trip blank was also included in the cooler containingthe groundwatersamplesto measure any environmental influences on the samplesduring storage andsmr

## transport.No VOCs were detected above their respective laboratory reporting limits in the field blank or trip blank during the current monitoring event.
1,1-DCAContaminant Trend Analysis and Request for Site Closure

An agreement was reachedwith the U.S. EnvironmentalProtection Agency (USEPA)that monitoring of well W

-27 would be conducted until the concentration of 1,1

-DCA (and other VOCs) in groundwater samples collected from that well remainedbelow MCLs for four consecutive semiannual sampling events,or a minimum of two years

.This closure criterion was determined during a meeting between LFR Inc. personnel andUSEPArepresentatives Herb Levine and Dante Rodriguezat EPA’s San Francisco office on January 31, 2006. This meeting was heldto address recommendations presented in theUSEPA report entitled “Second Five

-Year Report for the Sola Optical USA, Inc. Superfund Site, Sonoma County, California,” dated September 2005 (“the Second Five

-Year Report”). During a discussion related to Recommendation #1 in the Second Five

-Year Report,it was agreed that groundwater monitoring atwell W

-27 would be continued until it was demonstrated that the cleanup goal for 1,1

-DCA (i.e., the MCL [5 μg/l]) had been maintained for two years.
As shown in Table 2, 1,1

-DCA concentrations in well W

-27 have been below the MCL in three of the last four monitoring events, and have remained below the MCL since June 2010(greater than two years)

.In addition, the July 2012 1,1

-DCA concentration is the lowest ever detected in this well,indicating the continued attenuation of 1,1

-DCA. The1,1-DCEconcentration hasalso decreasedfrom the June 2010 concentration to below the laboratory reporting limit of 0.5μg/l. This is the first1,1-DCE concentration below the reporting limitin this wellsince November 2000.
The trend of 1,1

-DCA concentrations in well W

-27 was assessed using both the concentration

versus-time graph (Figure4) and a Mann

-Kendall trend analysis (Appendix B). The concentration trend graphpresents all 1,1

-DCA data collected at well W

-27 from 1987 through the present. The Mann

-Kendall analysis was conducted using 1,1

-DCA concentrations from 2003 through the present. This date range was selected because 2003 marked theimplementationof the monitored natural attenuationprogram at the Site

. As previously mentioned, the concentration-versus-time trend graph for 1,1

-DCA in W-27 illustrates a generallydecreasingtrend, especially from samples collected in 2003 to the present (Figure 4). This decreasing trend is furthersupported by the Mann

-Kendall trend analysisthat was conducted. As shown in Appendix B,a decreasing trend was calculatedwithhigh confidencefor the 1,1

-DCA concentrations in W-27.

Based on thetwo consecutive years of VOC concentrations below their respective MCLsand the decreasing concentration trend of 1,1

-DCAin well W-27,ARCADISbelieves the groundwater cleanup standards have been achieved andrecommendsthat monitoring well W

-27 and contingency wells E

-1, E

-2, and E

-4 be abandoned and sealed in accordance with Sonoma County Environmental Health guidelinesandthatthe Site beclosedby theUSEPA
