Subject: Investigation of Subsurface and Stockpiled Soil Conditions at the
Agua Hedionda Sewage Pump Station, Carlsbad, California
Introduction
Leighton and Associates, Inc. is pleased to submit this report which includes a
discussion of the results of the investigation of soil conditions at the subject
site. The objective of this investigation was to determine the likelihood of
petroleum hydrocarbon contamination of the soil beneath former onsite underground
diesel fuel tank, and stockpile of soil produced by excavation of the tank.
The scope of work for the subject investigation included collection of soil
samples from the tank excavation and soil stockpile, laboratory analyses of
13 soil samples, and preparation of this report. The following report includes
a map showing the location of the soil samples, the results of the field
investigation, a discussion of the laboratory results, and conclusions and
recommendations.

Site Description and Background
The site Is a sewage pump station that Is part of a sewage pipeline system that
boosts sewage up to a topographically higher level so that it can be routed to
a nearby treatment plant. The site is located near the south side of the Agua
Hedionda lagoon, east of the railroad tracks and 2,500 feet northeast of the San
Diego Gas and Electric (SDG&E) Encina Power Plant on Carlsbad Boulevard (Figure
1). The site can be accessed via a dirt road which runs parallel with the
railroad tracks and immediately east of the tracks. The dirt road can be
accessed from Cannon Road 1/4 mile west of Interstate 5, and north of Cannon
Road.
In addition to being powered by electricity, the pump housed at the site has an
emergency generator which is fueled by an underground diesel fuel storage tank.
The emergency generator is used to operate the pump station facility during
interruptions in San Diego Gas and Electric (SDG&E) electrical power service.
According to City of Carlsbad representatives, the fuel tank was installed in
1977, and is 1,000 gallons in capacity and made of reinforced fiberglass.
The City of Carlsbad had indicated to Leighton and Associates that a release had
occurred from a pipe fitting in the fuel supply line from the tank to the
generator. The release was discovered subsequent to removal of the tank and
associated piping on July 25, 1990. Subsequently, the city contracted Leighton
and Associates to collect soil samples from the pipeline and tank excavation for
analysis to evaluate which areas of soil had been contaminated by the release.
Field Investigation
On July 25, 1990, Leighton and Associates collected two soil samples from the
diesel fuel tank excavation (1-N-ll and l-S-10.5) at depths of 11 and 10.5 feet
below land surface (bis), and two soil samples from the pipeline excavation
(P-10'-2 and P-21'-2) at a depth of 2 feet bis at the locations shown in
Figure 2. The soil samples were collected using a hand-trowel that was cleaned
in a solution of trisodium phosphate (TSP) and water, and rinsed with deionized
water prior to collection of each sample. After collection, each sample was
placed in a laboratory supplied glass jar with a Teflon-lined cap and placed in
an ice-cooled container awaiting delivery to a Department of Health Services
certified laboratory, Analytical Technologies, Inc. (ATI) for analysis. Each
sample was analyzed by the laboratory for fuel hydrocarbons by Modified EPA
Method 8015/CDOHS.
- 2 -
4901121-02
The results of these analyses (Appendix B) are summarized in Table 1 and indicate
that fuel hydrocarbons were not detected above the laboratory detection limit in
soil samples 1-N-ll.O', l-S-10.5, and P-10'-2. However, fuel hydrocarbons were
detected in soil sample P-2T-2 at a concentration of 4,100 milligrams/kilogram
(mg/kg).
As a result of the above data, the City of Carlsbad excavated the soil in the
area of soil sample P-2T-2 to a greater depth in an effort to remove hydrocarbon
containing soil at a concentration above 100 mg/kg. On August 9, 1990, Leighton
and Associates collected an additional soil sample (T-l-4) from the excavation
in this area, and four soil samples (SP-1 through SP-4) from the stockpile
produced by tank excavation. The soil samples were collected in accordance to
the County of San Diego Hazardous Materials Management Guidelines. The soil
samples were collected as previously discussed, delivered to ATI for analysis for
fuel hydrocarbons and organic lead by EPA Method 6010. Soil samples T-l-4' and
SP-4 were also analyzed by EPA Method 8020 for benzene, toluene, ethyl benzene and
total xylenes (BTEX).
Laboratory Results
The results of analytical analyses are summarized in Table 1 and presented in
Appendix B, Chain-of-Custody forms and QA/QC data is also included in Appendix B.
The data indicates that fuel hydrocarbons and BTEX were not detected above the
laboratory detection limit in soil samples T-l-4' and SP-2. Organic lead was not
detected in any of the samples. However, fuel hydrocarbons were detected in 3 of
the 4 soil samples from the stockpile, i.e., soil sample SP-1 at a concentration
of 300 mg/kg, soil sample SP-3 at 330 mg/kg, and soil sample SP-4 at 140 mg/kg.
Based on the results of the above data, the city reported to Leighton and
Associates that they would be leaving the stockpiled soil on site so that natural
bioremediation would occur in hope of lowering the concentration of hydrocarbons.
Subsequently, the city informed Leighton and Associates that the stockpile had
been relocated and that they needed additional soil samples collected and
analyzed to evaluate the effectiveness of natural biodegradation of the
hydrocarbons in the soil. Therefore, on January 18, 1991 four more stockpile
samples were collected (SP-5 through SP-8) from the relocated stockpile. The
location of the sample collection points are shown on Figure 2. The stockpile
samples were collected in accordance with the HMMD sampling guidelines
(Appendix A, Reference 1). The samples were collected in the manner previously
described, and then delivered to ATI for analysis by Modified EPA Method 8015 for
fuel hydrocarbons. The soil samples with the highest fuel hydrocarbon
concentration (SP-6) was also analyzed by EPA Method 8020 for BTEX, EPA Method
6010 for organic lead, and EPA Method 1010 for flash point.
- 3 -
4901121-02
The results of analysis (Appendix B) are summarized in Table 1 and indicate that
fuel hydrocarbons were detected in soil samples SP-5, SP-6, SP-7 at
concentrations of 49, 120, and 62 mg/kg, but not above the detection limit in
soil sample SP-8. BTEX were not detected in soil sample SP-6, and the flash
point was greater than 180 degrees Fahrenheit.

CONCLUSIONS AND RECOMMENDATIONS
Based on the results of this field investigation, the following conclusions and
recommendations are presented.
• Based upon the laboratory results of soil sample P-21-2', the trench
excavation was deepened to remove the contaminated soil. A second sample was
then collected (T-l-4') below the point where sample P-21-2' was collected.
This sample was submitted for analyses of fuel hydrocarbons. No such
compounds were identified. Therefore, it appears that the contaminated soil
in the area of sample P-21-2 has been removed.
• The results of analysis of soil stockpile samples indicated fuel hydrocarbon
concentrations ranging from nondetection to 120 mg/kg.
• Following the determination that 4,100 mg/kg (as diesel) of fuel hydrocarbons
were detected in soil sample P-21-2, the excavation in the area of this
sample was deepened to 4 feet. A soil sample was collected from the base of
the trench and below the point where soil sample T-l-4 was collected. Fuel
hydrocarbons were not detected in this sample. Therefore, it is our opinion
that the petroleum hydrocarbon affected soil was removed from this area of
the excavation
• The four samples collected from the stockpile showed that the fuel
hydrocarbon contamination levels ranged from below the laboratory detection
limit and 120 mg/kg, and an average concentration of 58 mg/kg. Based upon
this analysis, it appears that the fuel hydrocarbons levels in the stockpile
have been reduced significantly.
Based upon the results of this investigation, we recommend no further action at
this time.
This recommendation must be approved by the County of San Diego-Hazardous
Materials Management Division (HMMD). Upon approval, a determination can then
be made regarding further usage of the soil i.e. for use on site or placement in
a Class III landfill. This determination must be made in conjunction and
agreement with the HMMD and Regional Water Quality Control Board (RWQCB).
