The property is located at the intersection of Golden State Highway and Union Avenue in Section 30, T.29S., R.28E., M.D.B.& M., Bakersfield, California. The triangular shaped property was the site of three 12.,000 gallon underground fuel storage tanks (see Figure 1). CONTAMINATION PROBLEM Subsequent to removal of the tanks, it was determined that significant hydrocarbon cOntamination of the subsurface had occurred. Three test holes were drilled on the property to delineate the vertical and horizontal extent and the level of contamination. Based on the chemical, analyses performed on soil samples collected from the test holes, plan and profile- maps of the extent and level of. contamination were plotted (see Figures 2 and 3). Figure 2 also shows the test hole locations. The contamination is not expected to pose a threat t° groundwater supplies. Groundwater-is in excess of-~-2'00-f-eet below the property PROF ! LE VI EW OF CONTAM!NAT ION EXTENT A 4~I J I / Lo0ati6n of profile A-A' is shown on Figure 2 T.H.=Test Hole. based upon. several water wells in the area operated by California Water Service Company. No shallow groundwater is known to exist in the general area. The Kern County Health Department required the extraction of vapors from the soil until an acceptable level of contamination is rg~ched. An acceptable~level is assumed to be 'the point at which the curve of contamination concentration'versus time levels out to a fairly constant value. VAPOR EXTRACTION SYSTEM Vapor EXtraction Wells Three extraction wells were emplaced in a triangular configuration centered over the area of highest contamination (see Figure 4). The wells were completed to a total depth of 45 feet using 2 inch P.V.C. casing in a 6 inch diameter hole. The casings were perforated from 15 feet to 45 feet utilizing 0.010 inch slots. The wells were gravel packed around the perforated intervals using 0.125 inch gravel. A bentonite seal was'emplaced from the surface to 15 feet deep (see Figure 4). Two inch P.VoC. casing was routed from each well ~o a central location for connection to the vapor extraction unit. V,A PO ~. EXTrACT/o~,/ WELL E.W.=Extraction Well Wells will be Capped until system is installed and ready to operate. Wells will be abondaned as per Health Department requirements upon completion of work. -ED.-4B Figure'4 Vapor Extraction Unit The vapor extraction unit consists of an air operated diaphram pump, air compressor, and activated carbon filter. The filter is composed of eight, l~engths~-0f 4 inch P.V.C. casing filled with activated carbon and interconnected sequentially so that .vapor flows lengthwise through all eight tubes. points are located on both the input and output hoses to the filter so that samples may be taken before and after the. vapor has passed through the filter medium. After passing through Vapor sampling the filter, the air is vented to the atmosphere. The vapor extraction unit is shown in Figure 5. ANALYSIS OF vApOR EXTRACTION System Operation Operation of the vapor extraction system began on February 25, 1987 and was performed discontinuously through June 23, 1987. Measurements of ~the hydrocarbon contamination levels during system-operation began on May 11, 1987 and continued through June 23, 1987. A summary, analysis, and projection based on these measurements is presented below. The system was operated discontinuously for 33 days during a 119 day period for a total of 204 hours of operation. Measurement of_~._the_inlet hydrocarbon.contamination levels began on May 11, ................. VAPOR EXTRACTION UNIT 4" PVC filter tubes containing activated carbon filter medium ,.... extraction connections air compressor air operated diaphram pump Figure 5 1987. A total of 12 days of operation were measured. Measurements were taken roughly every 30 minUtes with a GasTechtor Model 1314 Oxy/Surveyor. All values are reported in parts per million (ppm). Each contamination measurement was recorded along with the date and time of measurement. Raw ~Data Attachment A displays plots of the data on a daily basis. ~The abscissa shows the time of meaSurement (24-hour clock) and the ordinate shows the contamination level in ~pm. The date of each day's plot is also presented. No specific trends are apparent in these plots, however, there is a slight tendency for the first few values to be lower than the rest. In order to obtain a more meaningful representation of the day to day contamination levels present, the mean values of each day's readings were calculated. Attachment B displays the mean values for each day plotted in the corresponding day's location on calendars for May and June, 1987. Attachment B also includes a graph of these values. The abscissa shows the number of days of measurement with May 11 being Day 1 and June 23 being Day 44. The ordinate shows the daily average of the contamination levels in ppm. In general, this plot shows a significant decline in contamination levels. Unfortunately, there is a large data gap in the first 20 .days due to equipment failure of the vapor ext~a·ctiOh u~nit ............................... ;~ .............................................................................. 4 Statisticaol Analysis A statistical analysis of the data was performed on a Hewlett- packard HP-85 computer using a curve fitting program explained briefly in Attachment C. Attachment D shows statistical data and plots for the four curve ...... ~t~.m~hods described in Attachment C. ~The value of r2 is a measure of the quality of fit of the curve generated. The closer 'r2 is to one, the better the quality of fit 'and hence, the mole accurately the curve fits the data. From the values of r2, it can readily be seen that the linear regression and exponential curve fit methods are more accurate representations of the trend of the data than are the logarithmic and poWer curve fits. The difference between the r2 values of the linear and exponential curves is insignificant indicating no preference for one over the other. None of the curves fit the data particularly well. This is likely due to: (1) difficulty in maintaining consistent measurement conditions, (2) limited amount of data, and (3) the large, gap in data at the beginning of the measurement period. Attachment E shows projections backward and forWard in time based on the equations of the curves generated for the linear regression and exponential curve fits. On these plots, the o February 25, ~987, the first day of system operation, Day. 76 is the first day of measurement (May 11), Day 119 is the last day of operation and measurement (June 23), and Day 160 is the limit of the projected values. The ordinate shows the contamination level in ppm; the exponential plots scale is double that of the linear plots scale Based on these projections, the linear regression curve predicts, a value of 128.57 ppm for the first day of system operation. The exponential curve predicts a value of 238.28~ for the first day. The original test holes drilled in July, 1986 revealed hydrocarbon contamination levels of 300 to 800 ppm in the area that the. vapor, extraction system draws from. Based on these contamination levels, the exponential curve fit seems to be a better approximation of the contamination withdrawal rate. Projecting these curves forward, the linear regression plot shows the contamination level reaching zero at about 160 days and the exponential curve shows the contamination values.leveling off at about 20 ppm at 160 days. If the linear regression curve is a good approximation of the withdrawal rate, then significant further reduction in contamination levels can be achieved, if the exponential curve is the better approximation, then further reductions would not be very~significant. Intuitively, the linear regression-fit is not expected to be averylgood--approximation:~ ~a-steady decline to.zero ppm is ......................... 6 not likely~ The exponential curve does provide a good intuitive fit. It is likely that the rate of contamination reduction will decrease as the level of contamination decreases. Only further data collection can.verify this. CONCLUS I ON S Based on the results of this study, it is concluded as follows: It appears that a significant reduction'~n the subsurface hydrocarbon contamination has been achieved. Se Further reduction in the contamination level may be achieved through continued operation of the vapor extraction system. It is not known if this reduction would be significant. e More data Would increase the level of confidence of predictions about further vapor extraction. It is the opinion of these authors that an exponential decline in the rate of contamination reduction is the best model of the system. .. 5.

Exponential c'urves; y = aebx (a>0), 3. Logarithmic curves; y: a + blnx, 4. Power Curves; y: axb (a>0). The type of curve fit is specified after data is entered. Any curve can be specified by pressing the desired key. The data is entered initially from the keyboard, but can then be stored on the .tape for later use and updating. The program is designed for a maximum of 200 data pairs. The data which has been entered can then be edited and printed. Once. the curve fit has been selected, the regression values will be calculated. The coefficient ofdetemfination, r:. indicates the quality of fit achieved by the regression. Values orr: close to 1.00 indicate a better fit than values close to zero. The regression'coefficients, a and b, define the curve generated, according to the equations shown above. After the analysis of variance has been calculated and printed, you can plo~ the regression line over the data. Projec- tions can also be made based on the curve fit. You can either enter single values ofx or request that all values ofx in the data set be used to estimate values of)', .~. The analysis of variance which is printed for each regression type prints the following values: 1. Degrees of freedom 2i Sum of squares 3. Mean sum 4. F-ratio 5. 1-2 The value of the F-ratio is set to 999.9 if it is greater than 999.9. Therefore if the r: value is close or equal to 1, the value of the F-ratio will be printed as 999.9.

Ruettgers 1801 21st Street, Suite 4 Bakersfield, California 93301 Dea~ Mr. Ruettgers: .,~ The following is my proposal for Phase III of the Union Avenue Job No. 626. Results .from analyses of all.test holes have been received. It would appear, based upon these results, that contamination extends from 15 feet to 45 feet below the surface, with very slight contamination from 45 feet to 70 feet. The horizontal extent of the plume is about 60 feet in a north-south direction (see Attachments A and B).. Based upon the sediments encountered below the property, movement in an east-west direction should be very similar to that in the north- south direction. Chemical analyses of the samples from the three test holes are shown in Attachment C. Bill Bergmann of Kaman Tempo has conCluded that the vertical and horizontal extent of the plume has basically been defined. After analyses of Test Hole Nos. 2 and 3, Kaman Tempo recommended that we verify that no shallow groundwater exists in the area, install subsurface pore liquid migration detection instruments to monitor movement, and install in situ vapor monitoring wells. Groundwater is in excess of 200'feet below the property based upon several water wells in the area operated by California Water Service Company. No shallow groundwater is known to exist in the general area. Based upon our meeting with Kern County Health Department personnel, migration monitoring and in situ vapor monitoring wells were deemed unnecessary since the Health Depar.tment is requiring that.vapors be .extracted ~from the~highest ..... contaminated zone until an acceptable level is reached. The Mr. Ronald F ~'Ruettgers Decembers5, 1986 Page 2 acceptable level of contamination should be when the concentration level versus time curve levels out 'at a more or less constant value. Based upon the data gathered during Phase I and Phase II, I recommend the drilling of three vapor extraction wells, completed through that portion of the plume which showed the highest concentra%ions. These wells would form a triangle with sides of about 20 feet in length. ~They'would be completed to a depth of 45 feet. A bentonite seal would be placed from 15 feet to the surface. Attachment D shows the well construction and the Well locations. These wells will then be connected to the vapor extraction system. They would be vacuumed and vented in a number of combinations to find the most effective way to move the vapor. The vacuum extraction system will be comprised of an air operated diaphram pump, compressor, and activated carb~ filter. All ~ piping will be 2-inch P.V.C. and vapor sampling extraction~ points will be located on both sides of the filter. This will enable me to verify the effectiveness of the filter. Once filtered, the vapor will be vented to the atmosphere. Analysis of the vapor will be conducted on a regular time schedule which will be worked out once the system is installed and initially samples are analyzed. All analyses will be quantitative. The time to complete the vapor extraction to acceptable limits is not known at this time. We should be able to estimate the total time needed to extract the plume after the system has been in operation a short time. Sampling and sample management of vapor samples will be in accord with th~ sampling, planning, methodology, and equipment, and the sample processing, documentation, and custody procedures specified by the Environmental Protection Agency.

The samples were collected by Duane smith of EPC using hollow stem auger equipment. The sample containers used differ from those normally used by Kaman Tempo. The samples were collected in 100 ml plastic wide-mouth beakers with plastic snap caps. The beakers were in turn wrapped 'in plastic bags sealed by a rubberband. The samples were then placed with ice in an ice chest and shipped to Kaman Tempo via Greyhound. During shipment, the ~ ~ and 35 foot samples became saturated with wateE produced by melting ice. We suggest that any subsequent samples be collected in contaTners which are more water tight, preferably with screw-on tops. The soil samples were analyzed on July 3 and July 5, 1986 by Kaman Tempo, using a Photovac ~lO~3~togra~ equipped with a photoionzation detector. Each sample '~as analYzed by drawing 25 microliters of gas from the headspace.in each container and injecting it onto the GC column. Headspace from a benzene, toluene, xylene (BTX) - water solution was run on the GC prior to running the samples. The chromatogram from the BTX standard is shown in enclosure 1. No Total Hydrocarbon or EDB analyses were run. The chromatograms of the sample analyses are given in enclosure 2. Prior to each sample collec- tion, a blank was run to determine the background concentration in the syringe to be used in the sample injection. The background chromatogram appears above each sample chromatogram in enclosure 2.. The three compounds were identified by their relative elution times and their concentrations determined by visual estimation on a relative scale of trace to very high. The results of the analyzes are summarized in Table 1. Above 15 feet, no BTX or other compounds were detected by the Photovac GC. Significant concen- trations of 'BTX were detected between depths of 15 and 45 feet. Benzene concentration seems to $ncrease with depth from moderate at 15 feet to very high at 40 and 45 feet. Toluene concentrations appear to be high throughout this interval. Xylene concentration decreased within this interval. At a depth of 50 feet, BTX concentrations drop sharply, remaining low to .a_dept~_~ Mr. Duane Smith-' 7 July 1986 Page 2 65 feet. Only trace amounts .of BTX are found in the 70 foot sample. It should be noted that the 30 and 35.foot samples were totally saturated with water on ...... arrival -in Santa Barbara and were not analyzed becau'~ of the lack 'of soil vapor in the container. · WRB:sl Enclosures Sincerely, KAMAN TEMPO William R.

CALIFORNIA 93301 TELEPHONE (805) 327-9681 July 8, 1986 J JUL Mr. Ronald F. Ruettgers 1801"21st Street, Suite 4 Bakersfield, California 93301 ....... _Dear Mr. Ruettgers: The following is our proposal for Phase II of the Union Avenue Job No. 626. Results from analyses of samples from Test Hole No. 1 have been received. It would appear, based on these results, that contamination extends.from 15 feet to 45 feet below the surface with slight contamination from 45 to 60 feet. Samples at 65 feet and 70 feet did not register on the HNU meter and Kaman Tempo found only very slight contamination (p.p.b.) at these depths. Bill Bergman of Kaman Tempo concluded that the zone between 15 feet and 45 feet represents the vertical thickness of the plume of contamination below the tanks. Based on this data we recommend the drilling of two additional test holes to plot the horizontal migration of the plume. These two test holes should be drilled approximately 90 feet from Test Hole No. 1 (see Attachment). This is twice the vertical distance of migration and we expect these additional holes to intersect the edge of the plume. If no contamination' is encountered in the first test hole then the second test hole will be moved closer to Test Hole No. 1. Samples will be collected at 5 foot intervals beginning at E feet. Samples wil be checked with the HNU meter in the field. Kaman Tempo will analyze'samples with B. C. Laboratories analyzing selected samples fOr quantitative values. It should be noted that gas stations were present in the past at both the northwest and southwest corners of 21st Street and Union Avenue. We have been somewhat conservative in the placement of Test Hole Nos. 2 and 3 so as not to encounter possible contamination by these sources. If the plume is penetrated by Test Hole Nos. 2 and 3 the shape corresponding to vertical and horizontal migration cab be shown in cross-sections. .............

Investigation of contamination at Union Avenue and Golden State Avenue/Aramco Property. Dear Mr. Canas: Pursuant to recent conversations, this is to outline the status of our proposed investigation and plan of action concerning the above reference. After reviewing the proposal by IT Corporation, we solicited a proposal from EPC on a slightly different approach. A copy of their proposal is attached. At this time EPC propOses to utilize Mr. Duane Smith, Registered Geologist, to conduct the drilling, sampling and logging operations. They proposed to begin the drilling operation utilizing Lane-western. Per our previous conversation with Ms. Ann Boyce, of your department, we are proposinz ~o utilize your staff and HNu meter to det- ermine presence of contamination durin~ drillinK Opernti~n~. This cost would be compensa~d directly or through some sort of credit service transfer. The first hole would be at the point of greatest contamination previously found and we would, hope- fully, determine the lower limit in the first drilling operation. A decision would be made at that time for the best location on the perimeter to continue drilling operations. Contaminated materials would be tested by BC Laboratories. Kaman Tempo-of Santa Barbara, would be available to analyze the results and recommend a course of action for reveiw by your department. We have discussed the proceedure with City and County staff and the Greater Bakersfield Separation of Grade District. Under the Joint Exercise of Powers Agreement, the District has authorized an initial maximum alloCation of $20,000.00 to begin this work. continued At. this time, our schedule is to begin drilling on Thursday, June 19, 1986. ~Please contact me, should ~ou have any questions.

At the top of each casing, a 90° ell was attached so that pipes could be routed underground to a central location for connection of the filter unit to the extraction wells (see Attachment). Abandonment consisted of uncovering the wells to a depth of about 2 1/2 feet, removing the ells, and filling the well casing with concrete from top to bottom (see Attachment). 'The standpipes used for connecting the filter unit were removed below the surface. All excavations'were filled with dirt and replanted to minimize-disruption of the landscaping efforts.
