Converse Consultants Orange County ( Ccmv:erse ), on behalf of Red Eagle Properties, is pleased to present this Suii1rllary Report for Additional Site Characteriz~tion activities at the referenced. property. This report doctnri~nts the general activities at the referenced property associ::1.ted with tetrachloroethene (PCB) contamination, discovered during the removal of the southern clarifier. For site vicinity, see Figure 1.

\

Background

Two clapfiers were d,iscovered during a previ9us Preliminary Site Assessment of the subject property conducted by Converse in 1992. ·The clarifiers were located in the northeast section of the property. The clarifiers were removed in September 1994 (see Converse report dated October 18, 1994 ). ··

Two soil sampl~s (NG-1 from the north clarifier and SG-1 from the south clarifier) were obtained from the bottom of the clarifier exQavations from depths of approximately 12 feet below ground surface (bgs) llD,der the direcifon of Mr. Mike McCall of the Orange County Health· Care Agency (OCHCA) and submitted to a state certified laboratory for analysis. The soil samples were analyzed in accorq~ce with United States E:p.vironmental Protection Agency (EPA) methods 801,0 (halogenated volatile organics) and 418.1 (total recoverable petroleum hydrocarbons [TRPH]), and California Code of Regulations Title 22 metals.

Sample NC-1 revealed 16 parts per million (ppm) 0£ TRPH. Trace amounts of several metals were detected, but all detected metals were below the regulatory action levels established in CCR Title 22 for persistent and bioaccumulative toxic substances. No target compounds of halogenated volatile organics were detected in NC-1.

Orange County Health Care Agency December 13; 1994 Page 2

Sample SC-1 revealed 27,000 ppb of PCB and 3,600 ppm of 1RPH in the soil. Trace amounts of several metals were detected, but all detected metals were below the regulatory action levels established in CCR Title 22 for persistent and bioaccumulative toxic substances. See Figure 2 for the site layout map.

Converse conducted a limited site characterization study on October 21, 1994·. The study consisteq of advancing one borifig to a depth of 40 feet below ground surface and obtaining soil samples at five foot intervals. Th~ soil samples were then analyzed for PCB in accordance with EPA method 8010 and TRPH in accordance with BP A method 418.1. Low levels of PCB and TRPH were found in the soil (see Converse report dated November 11, 1994). .

We were then advised by you that the Regional Water Quality Control Board verbally requested three additional borings be advanced to verify that contamination had not spread laterally.

Field Activities

On December 2, 1994, Converse advanced six (6) soil borings (BH-2 through BH-7) using a Geop:robe Systems sampling technique. lnjtial depths of 15 feet bgs were targeted for investigation. Soil samples were obtained from 15 feet bgs, and were field screened using an organic vapor analY?;er (OVA). Soil samples were then submitted to an on-site mobil laboratory for analysis. Borings from which the soil sample exhibited elevated levels of PCB were adva,nced further, and samples were obtained at five-foot intervals. Additional borings were located based on soil analytical results from previous borings. At the completion of the boring activities, the boreholes were backfilled with bentonite chips and hydrated with purified water. See Appendix A for field methodologies.

Soil Analytical Results

A total of 17 soil samples were submitted to tqe mobil laboratory for analysis. The samples were analyzed in accordance with EPA methods 8010 (PCB). The analytical results, along with the results from boring BH-1 (see Converse report dated November 11, 1994) are tabulated as follows:

Generally, the subsurface soil conditions consist primarily of clayey silts and silty clays encountered at approximately 15 feet bgs and extending to approximately 20 feet bgs. Some fine grained sand with silt was encountered at 20 feet bgs in BH-2 and BH-3, extending to approximately 40 feet bgs in BH-2, where more clayey silt was encountered. See Appendix C for the boring logs.

Ground water was not encountered in any borings, and is estimated at a depth of approximately 60 feet bgs in the area, based on information obtained from near-by monitoring wells. The gradient is believed to be towards the southwest.

Conclusions

Based on the findings from the additional characterization activities, it appears that contamination of the soil from PCB exists laterally to the west and northwest of the former clarifier. Concentrations of PCB detected during the characterization study ranged from not detected to 96,000 ppb (96 ppm). However, based on the nature of the soils (silts and clays) and the existence of c<>ncrete and asphalt barriers, we believe it is unlikely that the detected contamination will effect the occupants of the building on the property.

Limitations

The fi_p_dings presented herein are based on our evaluation of currently available data and were prepared in accordance with g~nerally accepted environmental principles common to the local area in which we practice. We make no other warranty, either expressed or implied.

Converse is not responsible for the accuracy of information provided by others. This report should not be regarded as a gu11rarttee that :no subsurface contamination is present at the' property b~yoncl wp.at has beeh diselos~d. 'Ipere may be subsurface conditions that cannot be reasonably predicted with the services pe{f ormed to-date.

FIELD METHODOLOGIES

Geoprobe Advancement

The exploration program for this study consisted of Geoprobe probe advancement and drive sampling for the collection of soil samples. The probe was advanced on December 2, 1994 by Pacific On-Site Services using a Geoprobe Systems probing machiile.

Probe advan,cement was conducted such that the locatic:>ns were open to the atmosphere (air.;.fillecl) during adv~cernent. No fluids, including clean water, or additives were used during probe advancement.

Drive soil S3.ID.ples were collected from the prqbe locations at spe.¢ified deptli iritervals (typica,lly 5-foot) .. Sqil satnpl~s were obtained by driving a 1-inch <liarneter st.eel driving,.mbe at tpe epd of a percussioµ drill steel. The sampling tube was equipped with ~ steel drive head which was withdra~ via the exte11ding rdd, at the upper limit of the desfredsampie intervai. 'Ibe tube was tbeu driven into die undisturbed. soifand an approximately 100 gtzjfr sample was collected over a 1-foot vertical interval; The sample was then brought to the, grourid surface by withdrawing the sections of drill steel.

After the sampler was removed from the probe location, the sc:>il sample for chemical analyses was inspected to verify that there was no head space in the sample. If gravel extended from the sample, or head space was observed in the soil sample, the sample was considered invalid and an additional attempt was made to collect a valicl sample. If the retrieved sample was considered valid, the brass sleeve was covered with teflon sheeting and tightly capped.

One~ at the ground surface, the soil sampling tube was capped, placed into a polyethylene bag, labeled, and immediately submitted to an on-site mobil laboratory for analaysis. Soil samples were collected, stored, transported and analyzed in accordance with JIPA Sample Collection Codes. A Chain-of-Custody record was niaintained throughout the operation. Anzjytical Laboratories. of Orange, California (State c~rtified laboratory) chemically analyzed selected samples in accordance with EPA Method 8010.

After a soil sample was collected, the sampling equipment was washed with alcanox and rinsed.

Chain-of-Custody Procedures \

Chain.;of-Custody pro~edures were maintained for all soil samples collected. This form was complet~d by the sample collector before releasing the samples to the laboratory. The chain-of-custody form was routed with the samples through transportation and analyses.

Cmnpleted c1J=1io-of-custody forms were returned to Converse along with the results from the a11alytical laboratory. These fornis are retaitied by Converse in the Central Project Files, and are included in Appendix B.
