Subject: Groundwater Monitoring Report, July through December 2012, Former Sola Optical 

U.S.A., Inc., Facility, 1500 Cader Lane, Petaluma, California

Dear Mr. Rodriguez:

This report presents the results of groundwater monitoring activities conducted during the period 

from July through December 2012 at the Former Sola Optical U.S.A., Inc., facility located at

1500 Cader Lane in Petaluma, California (“the Site”; Figure 1). ARCADIS U.S., Inc. 

(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 August 2012 in 

accordance with the groundwater monitoring program for the Site.

On July 25, 2012, ARCADIS personnel measured depth to groundwater in monitoring well W-27 

and former extraction wells E-1 and E-2 (Figure 2) and collected a groundwater sample from well

W-27. The water level was not measured in former extraction well E-4, because a large vehicle 

was parked over the well box. 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 three well 

casing volumes of water were purged, 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 was shut down on March 23, 1997. Historical 

groundwater elevations are presented in Table A-1 (Appendix A).

Table 2 presents select analytical 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 Table A-2 (Appendix A). The certified laboratory analytical report and water-quality 

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

in recent monitoring events) detected during the July monitoring event are presented on Figure 3. 

Groundwater Elevations

Groundwater contours were not prepared for this sampling event because 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 southsouthwest, 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, only one VOC (1,1-DCA) was detected in the groundwater 

sample collected from well W-27. 

1,1-DCA. 1,1-DCA was detected in the samples collected from well MW-27 at concentrations of 

1.7 micrograms per liter (μg/l) and 1.6 μg/l (primary and duplicate samples) in August 2012. 

These concentrations of 1,1-DCA are below the maximum contaminant level (MCL) of 5 μg/l. 

A graph of 1,1-DCA concentrations versus time for well W-27, presented on Figure 4, illustrates

an overall decreasing trend since October 2003. 

1,1-DCE. 1,1-DCE was not detected above the laboratory detection limit in the groundwater 

sample from W-27 during the reporting period. This is the first 1,1-DCE concentration below the 

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

time for W-27 is presented on Figure 5. As shown on Figure 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 

demonstrate that the sampling equipment was not contributing any VOCs to the groundwater 

samples. A laboratory-provided trip blank was also included in the cooler containing the 

groundwater samples to measure any environmental influences on the samples during storage and 
smr-Sola-Aug2012-EM001954 3

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-DCA Contaminant Trend Analysis and Request for Site Closure

An agreement was reached with the U.S. Environmental Protection 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 remained below 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 and USEPA representatives Herb 

Levine and Dante Rodriguez at EPA’s San Francisco office on January 31, 2006. This meeting 

was held to address recommendations presented in the USEPA 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 [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. The 1,1-DCE concentration has also 

decreased from the June 2010 concentration to below the laboratory reporting limit of 0.5 μg/l. 

This is the first 1,1-DCE concentration below the reporting limit in this well since November 

2000. 

The trend of 1,1-DCA concentrations in well W-27 was assessed using both the concentrationversus-time graph (Figure 4) and a Mann-Kendall trend analysis (Appendix B). The concentration 

trend graph presents 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 the implementation of the monitored 

natural attenuation program at the Site. 

As previously mentioned, the concentration-versus-time trend graph for 1,1-DCA in W-27 

illustrates a generally decreasing trend, especially from samples collected in 2003 to the present 

(Figure 4). This decreasing trend is further supported by the Mann-Kendall trend analysis that was 

conducted. As shown in Appendix B, a decreasing trend was calculated with high confidence for 

the 1,1-DCA concentrations in W-27. 

Based on the two consecutive years of VOC concentrations below their respective MCLs and the 

decreasing concentration trend of 1,1-DCA in well W-27, ARCADIS believes the groundwater 

cleanup standards have been achieved and recommends that 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 guidelines and that the Site be closed by the USEPA.

Groundwater Elevation Data

(1997 to Present)

Former Sola Optical U.S.A., Inc., Facility

All elevations in feet above mean sea level

Well Number Date Well Elevation DTW GWE

Petaluma, California

Notes:

DTW = Depth to water

GWE = Groundwater elevation

--- = Not measured

* = Well destroyed

(1) = The stovepipe well box was replaced with a flush-mounted well box. The well casing was then 

cut and finished several inches below grade.
