# ] Dear Mr. Rodriguez: This report presents the results of groundwater monitoring activities conducted during the period from July through December 2009 at the Former Sola Optical U.S.A., Inc., facility located at 1500 Cader Lane in Petaluma, California ("the Site"; Figure 1). LFR Inc. an ARCADIS company (now fully integrated and known as ARCADIS) conducted these activities at the Site on behalf of Carl Zeiss Vision Inc. (purchaser of American Optical, Sola [formerly Sola Optical U.S.A., Inc.]). Work Performed During the Reporting Period 

## Groundwater Monitoring Activities ARCADIS conducted semiannual groundwater monitoring activities at the Site in December 2009 in accordance with the groundwater monitoring program for the Site. On December 30, 2009, ARCADIS personnel measured depth to groundwater in monitoring well W-27 and former extraction wells E-1, E-2, and E-4 (Figure 2) and collected a groundwater sample from well W-27. Well W-27 was purged using a clean, disposable polyvinyl chloride (PVC) bailer prior to collection of a sample. Groundwater pH, temperature, specific conductance, and turbidity were measured following the purging of each well casing volume. After purging two well casing volumes of water, MW-27 dewatered. The well was sampled after allowing the groundwater to recharge for approximately two hours. Samples were collected using a clean, disposable PVC bailer at the well. Collected samples were decanted into 40-milliliter volatile organic analysis vials (VOAs) preserved with hydrochloric acid and labeled with the project number, well number, date, time, and analytical method. The lid of each VOA was then secured with a chain-of custody seal, and the VOAs were stored in an ice-cooled chest and transported 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 Agency Method 8260B (using an 8010 analyte list). 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 (GWETS) was shut down on March 23, 1997. Historical groundwater elevations are presented in Table A-1 (Appendix A). Table 2 presents analytical results from this sampling event. Historical analytical results for the Site are presented in Table A-2 (Appendix A). The certified laboratory analytical report and waterquality field sampling sheets are on file at ARCADIS. 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) detected during the December m<?nitoring event are presented on Figure 3. 

## Groundwater Elevations Groundwater contours were not prepared for this sampling event as only four wells remain and the spatial relationship of the wells is too close to provide an accurate depiction of groundwater flow. Shallow groundwater flow at the Site has historically been toward the south-southwest, in the general direction of the Petaluma River, since environmental investigations began at the Site in 1986. 

## Concentrations of 

## VOCs Consistent with previous data, only two VOCs (1,1-DCE and 1,1-DCA) were detected in the groundwater sample collected from well W-27. 

## 1,1-DCE. The concentration of 1,1-DCE in groundwater in well W-27 was below the maximum contaminant level (MCL) of 6 micrograms per liter**(~-tg/1).** 

## As shown on Figure 4, the concentration of 1, 1-DCE in this well has been below the MCL since April2002
. 

## 1,1-DCA. The concentration of 1,1-DCA detected in the sample collected from well MW-27 was 6.5**~g/1** 

## in December 2009. This concentration of 1,1

-DCA was slightly above the MCL of 5**~g/1.** 

## The detected concentration of 1, 1-DCA in well W-27 has increased slightly since the May 2009 sampling event from 4. 7**~g/1** 

## to 6.5**~g/1.** 

## However, concentrations of 1, 1-DCA are still lower than the high concentration of 21**~g/1** 

## in a sample collected in 

## October 2003. A graph of 1, 1-DCA concentrations versus time for well W-27, presented on Figure 5, illustrates an overall decreasing trend since October 2003.

### Proposed Further Monitoring and Site Closure Criteria 

## Carl Zeiss Vision Inc. will continue semiannual groundwater monitoring activities at the Site in accordance with the site groundwater monitoring program. We understand that monitoring of well W-27 will be required until the concentration of 1,1-DCA (and other VOCs) in groundwater samples collected from that well remain below MCLs for four consecutive semiannual sampling events (i.e., two years). This closure criterion was determined during a January 31, 2006 meeting between LFR Inc. personnel and U.S. Environmental Protection Agency (EPA) representatives Herb Levine and Dante Rodriguez. LFR Inc. attended the January 31, 2006 meeting at the EPA's offices in San Francisco to address recommendations presented in the EPA 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 at well W-27 would be continued until it was demonstrated that the cleanup goal for 1,1-DCA (i.e., the MCL [6 JLg/1]) had been maintained for two years. After that two-year period, monitoring well W-27 and contingency wells E-1, E-2, and E-4 could be abandoned and sealed in accordance with Sonoma County Environmental Health guidelines, and the Site could be closed. Please call Scott Seyfried at (916) 786-0342 or Daren Roth at (510) 596-9558 with any questions or comments regarding this report. Sincerely,

J. Scott Seyfried, P.G., C.HG. Principal Hydrogeologist
