1. Executive Summary
Dudek was contracted by the City of Carlsbad to determine if the contractor's soil
removal action had adequately removed lead-impacted soil from the former shooting
range to the extent necessary.
The former shooting range is located off of Faraday Avenue in Carlsbad, California in an
area to be developed as the Carlsbad Municipal Golf Course. Prior to Dudek's
involvement, the backstop of the shooting range was removed, along with the concrete
and gravel floor (Appendix A, Photograph 1). Approximately 8 feet of soil was removed
from behind the former backstop and some soil was removed from the side berms of the
former shooting range (Appendix A, Photograph 2). The soil was piled in six piles on the
dirt floor of the former shooting range following removal of the original concrete and
gravel floor. The piles were separated by the contractor into areas believed to either
contain high concentrations of lead or possibly contain only low levels of lead based on
visual observation (Appendix A, Photograph 3).
Dudek analyzed soil from behind the former backstop, from the side berms and floor of
the former shooting range, and from the soil stockpiles. A Niton XLP303A x-ray
fluorescence (XRF) meter was used to measure the approximate concentrations of lead in
the shallow soil. The sampling indicated that the majority of the remaining back wall and
side berms contained lead at concentrations less than 500 milligrams per kilogram
(mg/kg). The majority of the floor; however, contained high concentrations of lead. As
the majority of the floor of the shooting range was previously covered in concrete, it is
likely that the soil in the floor area was inadvertently contaminated during removal of the
soil behind the backstop (the contamination was spread out on the floor). Dudek
recommended that the top layer of soil on the floor be scraped and removed.
After the floor had been-scraped by the contractor, Dudek collected confirmation soil
samples from the floor and some additional soil samples from a soil pile and from the
walls. The samples were analyzed by Del Mar Analytical for total lead and for leaching
characteristics of lead using the synthetic precipitation leaching procedure (SPLP).
Evaluation of the soil sample results indicated that additional soil needed to be removed
from the floor area. The results of the leaching study were that lead does not leach from
the soil at concentrations that would impact fresh water aquatic life based on the Regional
Water Quality Control Board (RWQCB) 2003 Water Quality Goals.
In order to address the elevated concentrations of lead in the soil in the floor area, the
contractor removed approximately four inches of soil from the floor and placed the
material directly into bins to be removed from the site. Dudek collected confirmation soil
samples from the floor of the former shooting range. The concentration of lead in the
samples was generally less than 500 mg/kg.

Based on the sampling conducted, the soil remaining at the site was determined to have
lead concentrations low enough to not create a risk to human health or the environment.
The results of the variotis rounds of sampling indicated that the soil remaining at the site
would not create an unacceptable risk to human health under the industrial use scenario
(concentrations of total lead were less than the US Environmental Protection Agency
[EPA] preliminary remediation goal [PRG] for the industrial/commercial scenario of 800
mg/kg).
2. Introduction^
2.1. Scope of Investigation
Some soil at the former shooting range was conta;minated due to spent lead
ammunition. The majority of lead-contaminated soil was located behind and
near the former backstop of the shooting range. The majority of this soil was
stockpiled on the site and subsequently removed from the site and disposed of
off-site. The scope of this environmental investigation consisted of an initial
soil screening event for lead, a soil sampling event for total lead and leaching
characteristics, and confirmation sampling events to determine if the soil
remaining at the site could be left in place.
Based on the site plans, the former shooting range is to be covered with
approximately 10 to 15 feet of fill and is to be redeveloped as part of the
Carlsbad Municipal Golf Course.
2.2 Qualifications of Environmental Professionals
The soil screening was conducted by Nicole Peacock, a professional engineer
certified by Niton to use XRF meters for lead testing. The soil sampling was
conducted by Ms. Peacock, Trey DriscoU, and Kayvan flkhanipour; engineers
and geologists with proper OSHA hazardous materials training (HAZWOPER
training) and at least 5 years of relevant experience. Del Mar Analytical, the
laboratory that analyzed the soil samples, maintains National Environmental
Laboratory Accreditations (NELAC/NELAP) and appropriate California
certifications for lead analysis by EPA Method 601 OB.
3. Site Location
The former shooting range is an approximately 100 foot by 200 foot area in the canyon
south of Faraday Avenue between Canon Road and Camino Hills Drive in Carlsbad,
California (Figure 1). The site includes the berms on the east and west sides of the
former shooting range and the wall on the south edge. The site is within parcel
2120101500.
Site Investigation/Confirmation Sampling 4810-4
Former Shooting Range, Faraday Avenue Dudek & Associates, Inc.

The site is surrounded by land currently being graded for development as a golf course.
The site is located near a creek that discharges to Agua Hedionda Lagoon.
4. Site Investigation and Confirmation Sampling
The investigation consisted of an initial soil screening event for lead and a soil sampling
event for total lead and leaching characteristics. Several rounds of confirmation sampling
were also conducted.
Small arms firing ranges are not regulated unless the spent ammunition is abandoned and
left to accumulate for a long period of time or unless the range poses an imrhinent danger
to human health or the environment (US EPA 2003). Therefore, the site was not
regulated by any agency. The US EPA preliminary remediation goals (PRGs) were used
for the site in order to determine if the soil to remain at the site would pose a risk to
hurnan health. The PRG for industrial/commercial use is 800 mg/kg. Additionally, the
National Ambient Water Quality Criteria (NAWQC) for fresh water aquatic life were
used to evaluate the potential impact of soils left at the site on the environment. The
NAWQC for lead is 0.48 milligrams per liter (mg/1), based on a surface water hardness of
1,100 mg/1 as CaCOa, which was the hardness of a sample collected from the surface
water from the near-by creek on October 13, 2005 (Appendix B).
4.1 Initial Soil Screening
On September 30, 2005, Dudek screened the site for elevated concentrations
of lead in the soil. Dudek used a Niton XLP303A XRF meter to screen the
soil in the backstop, the side berms, the stockpiled soil, and the floor for
concentrations of lead. The Niton XRF meter can be used in two ways; as a
screening tool to measure approximate concentrations of in-place soil or as a
sample analysis tool to analyze the concentration of a prepared soil sample. Li
order to evaluate approximate lead concentrations in as many areas as possible
throughout the site, Dudek used the XRF meter as a screening tool. As a
screening tool, the measurements involve a moderate amount of error, which
is reported as milligrams per kilograms along with the measured lead
concentrations on Table 1. Regardless of the error, the meter is an effective
. tool in screening out elevated lead concentrations.
Approximately 220 measurements were taken in situ (on the ground or wall
surface, without sample preparation; Appendix A, Photograph 4).
Measurements were taken at 10 foot intervals along the back wall from each
of three different heights along the back wall (approximately 2, 4.5, and 7.5
feet above the ground surface; Appendix A, Photograph 5). Additional
measurements were taken in areas with elevated lead concentrations. For
example, six additional samples were collected from the back wall near
Reading No. 300. The six additional samples (No. 314-319) indicated that
the elevated lead concentrations were in a small area around Reading No. 300..
Site Investigation/Confirmation Sampling 4810-4
Former Shooting Range, Faraday Avenue Dudek & Associates, Inc.
Carlsbad, California .3 4/5/2006
Based on this data, a small amount of soil near Reading No. 300 was removed
and placed in the stockpile awaiting off-site disposal. A few yards of soil
were also removed from the left corner of the wall near Reading No. 393 due
to elevated lead concentrations.
Fifty-one measurements were taken from the back wall, 43 measurements
were taken from the corners and side berms, and 87 measurements were taken
from the floor. Six to eight rrieasurements were taken from each of the small
stockpiles (Stockpiles No. 1 and 3) and 22 measurements v^ere taken from the
large stockpile (Stockpile No. 2). These areas are shown on Figure 2.
Concentrations ranged from less than 50 milligrams per kilogram (mg/kg) to
6,581 mg/kg (Table 1). Concentrations in the wall and berms that were
greater than approximately 700 (plus or minus the specified error) were
removed and stockpiled as discussed above. Based on this screening, the
remaining soil in the back wall and side berms could remain in place, although
soil samples were collected and analyzed by a laboratory at a later date to
confirm that the soil could remain in place. This additional sampling is
discussed in the subsequent sections.
The concentrations of lead in the two small stockpiles (Stockpiles No. 1 and
3) were generally less than 100 mg/kg. Based on this data, this soil does not
need to be removed from the site. However, the screening of the larger
stockpile (Stockpile No. 2) indicated that the pile contained moderate
concentrations of lead. Therefore, Dudek recommended collecting soil
samples from the stockpile for analysis by a laboratory. This was done in the
October 13, 2005 sampling event discussed in the next section.
Several measurements taken on the floor (ground surface of the former
shooting range) contained elevated concentrations of lead; therefore, Dudek
recommended that the majority of the floor be scraped to remove a few inches
of soil. As the majority of the floor of the shooting range was previously
covered in concrete, it is likely that the floor was inadvertently contaminated
during remediation of the backstop (the contamination was spread out on the
floor).
The XRF meter self-calibrates when it is turned on. The self-calibration
readings are noted in Table 1 as SHUTTER CAL. fti addition to those basic
calibrations, the meter was checked against blank (0 mg/kg), low (18.9 +/- 0.5
mg/kg), medium (1162 +/- 31 mg/kg), and high (5532 +/- 80 mg/kg) standards
throughout the day. The standards checks, conducted eight times during the
day, were within these ranges.

4.2 Soil Sampling
On October 13, 2005, Dudek conducted soil sampling of the floor, the berms,
the backstop, and one remaining soil pile (Stockpile No. 2). The stockpile,
which contained .borderline concentrations of lead (several hundred mg/kg)
based on the lead screening, was sampled to determine if the pile needed to be
disposed of as hazardous waste. According to the California Code of
Regulations, waste soil is hazardous if the concentrations of lead exceed the
total threshold.concentration limit (TTLC) of 1,000 mg/kg. The soil samples
were collected in 4 ounce glass jars and sent to Del Mar Analytical for
analysis. The results for four samples from the stockpile were between 1,800
and 32,000 nig/kg (Figure 3). Dudek informed the City of Carlsbad and the
contractor of these results and stated that the pile should be removed and
disposed of as hazardous waste (Appendix C). A discussion of the waste
disposal activities is presented in Section 5.
Four soil samples were collected from the back wall and side berms to
confirm the conclusion from the soil screening that the remaining soil could
be left in place (Figure 3). The samples were collected at approximately eye
level. The samples, also analyzed by Del Mar Analytical, contained
concentrations of lead ranging from. 38 to 280 mg/kg. This sampling
confirmed that the soil remaining in the berms and the back wall could be left
in place without creating a risk to human health (the lead concentrations were
less than the PRG of 800 mg/kg).
Dudek collected soil samples from the surface of the floor, as the contractor
had stated that the floor had been scraped at least three times. Dudek
collected 18 samples from the floor, including 2 from underneath the
Stockpile No. 2 and 2 from underneath the concrete pile (Figure 3). The
sample results indicated that the floor had not been adequately scraped as
elevated concentrations remained. The samples collected from under the piles
indicated that the soil under the piles had not been contaminated in the same
way as the rest of the floor. This finding enforces the theory that the majority
of the floor had been inadvertently contaminated during remediation of the
backstop. As scraping the floor had not adequately remediated the lead
contamination, Dudek recommended digging down three to four inches to
remove the soil. Dudek recommended that the work start near the back wall
and work its way back through the former shooting range, with the backhoe
• . ' staying on contaminated soil so as not to contaminate clean soil.
In addition to collecting and analyzing soil samples for total lead
concentrations and comparing them to the PRGs, soil samples were also
collected and analyzed for leaching characteristics of lead from the soil. More
than half of the 26 soil samples collected during this sampling event were
analyzed for.leaching characteristics using the synthetic precipitation leaching

I procedure. SPLP sample preparation uses deionized water, adjusted to a pH
of 5.0, to simulate leaching that may occur at the site due to rain. This
procedure is more appropriate for this site than the toxicity characteristic
leaching procedure, which uses acetic acid to simulate landfill leachate. The
concentrations of lead in the SPLP leachate ranged from less than the
detection limit of 0.10 mg/1 to 0.14 mg/1. These concentrations are less than
the NAWQC of 0.48 mg/1; therefore, the lead concentrations in the soil are not
likely to significantiy impact the freshwater aquatic life in the near-by creek
through leachate.
Four background soil samples were collected from another area of the
proposed golf course to determine the background level of lead in the area.
The background samples were sent to Del Mar Analytical and were handled in
a similar fashion as the site samples. The concentrations of lead in the
background samples ranged from 3.6 to 8.7 mg/kg.
The information presented in this section was reported to the City in a
memorandum dated October 18, 2005 (Appendix C). The laboratory
analytical report for this sampling event is presented in Appendix D.
4.3 Confirmation Soil Sampling
In order to ensure that removal of 4 inches of soil from the floor would be
sufficient to remediate the site, the contractor dug 10 test pits to depths of 4
inches (Appendix A, Photograph 6). Three of the 10 test pits were excavated
to two different depths; half of the pit. was excavated to 4 inches, while the
other half was excavated to 6 inches. Dudek sampled the test pits on October
19, 2005. The samples were analyzed by Del Mar Analytical for total lead.
The concentrations of lead in the test pit samples ranged from 5.4 mg/kg to 42
mg/kg. The concentrations of lead in the four inch test pits were not always
higher than the concentrations in the six inch test pits. Therefore, Dudek
recommended removal of the floor (except for the area under the Stockpile
No. 2 and the concrete pile) to a depth of four inches.
The excavation of the floor was completed in December 2005 and Dudek
conducted confirmation sampling on December 13, 2005 (Appendix A,
Photograph 7). Eight samples were collected from the floor and placed in 4
ounce glass jars (Appendix A, Photograph 8). The samples were analyzed by
Del Mar Analytical for total lead. The sample concentrations ranged from 6
to 510 mg/kg, with the majority of the sample concentrations being less than
200 mg/kg. As these sample concentrations and those from the test pits are
less than the PRG of 800 mg/kg, the remaining lead concentrations do not
pose an unacceptable risk to human heahh and therefore, may remain in place.

The sample locations and results are shown on Figure 4. The laboratory
analytical reports for these confirmation samples are presented in Appendix E.
4.4 Soil Sampling Quality Assurance/Quality Control
Laboratory quality assurance/quality control (QA/QC) samples were analyzed
to evaluate the precision of the data. Del Mar Analytical analyzed three sets
of QA/QC data for the soil samples collected on October 13, 2005, one set of
QA/QC data for the test pit confirmation samples collected on October 19,
2005, and one set of QA/QC data for the confirmation samples collected on
December 13, 2005 (Appendix D and E).
Each set of QA/QC data included a blank analysis, analysis of a laboratory
control spike, and analysis of a spiked sample from the site. All spiked
samples were spiked with 50 mg/kg of lead. The laboratory blanks for each of
the five QA/QC sets did not contain detectable concentrations of lead. The
percent recovery of the spiked laboratory control spikes ranged from 90% to
107%, which is within the limits of 80% to 120%. The percent recoveries of 3
of the 5 rriatrix spike/matrix spike duplicates (MS/MSDs) ranged from 94%) to
106%). These three site samples had source concentrations of less than 20
mg/kg. The two MS/MSDs with percent recoveries out of the range of 75%) to
125%) had source concentrations greater than 100 mg/kg. The laboratory
reported that samples with high levels of analyte in the. sample do not provide
useful spike recovery information and that the blank spike should be used to
evaluate spike recovery. The relative percent difference between the matrix
spike and the matrix spike duplicate for the samples with source results less
than 20 mg/kg ranged from 0% to 9%o. These QA/QC data indicate that the
sample data is usable.
5. Disposal of Contaminated Soil
Contaminated soil from the site was placed in roll-off bins and removed from the site.
The contractor, SEMA Construction, contracted with Waste Management to remove the
lead-contaminated soil froin the site and transport it to a site that accepts such material
(Appendix F). Waste Management hauled the soil to Moody's El Corazon Reclamation
in Bonsall, California (Appendix F). The contractor, SEMA Construction, informed
Waste Management that the soil was contaminated with lead (Appendix F).
6. Conclusions
Dudek conducted a soil screening and soil sampling to determine the concentrations of
lead remaining in the soil at the former firing range and to determine the concentrations
of lead in leachate at the site. Based on the initial screening and initial soil sampling,
some additional soil was removed from the comer of the back wall and the majority of
the floor was removed. Confirmation soil sampling indicated that the remaining soil
Site Investigation/Confirmation Sampling 4810-4
Former Shooting Range, Faraday Avenue Dudek & Associates, Inc.

contained lead at concentrations less than the US EPA PRGs for the industrial/
commercial scenario of 800 mg/kg. Additionally, based on SPLP tests of the site soil,
leachate from the site would not significantly impact freshwater aquatic life in the near-
by creek (the leachate concentrations were less than the NAWQC limits for freshwater
aquatic life of 0.48 mg/1). Based on the comparison of site concentrations to these two
remediation goals, the remaining soil at the site can remain at the site. The remaining soil
is to be covered with 10 to 15 feet of fill soil during redevelopment of the site as a golf
course.
7. Limitations
The findings and conclusions presented in this report are based solely upon the indicated
data described in this report, the visual observations of the site, and a review of SEMA's
affidavit. Dudek did not coordinate or provide oversight for the soil removal activities or
the off-site disposal or recycling of the contaminated soil.
The scope of this investigation was limited to evaluating the potential impacts on human
health and the environment of the former firing range activities and site remediation
activities within the approximately 100 by 200 foot former firing range and providing
recommendations for remediation of the lead contamination at the former firing range as
discussed in this report. The investigation did not extend outside of the approximately
100 by 200 foot former firing range.

RE: Carlsbad Former Shooting Range Lead Concentrations
The following is a quick synopsis of the soil sampling that was done, the results, and
disposal recommendations.
Lead Screening - 9/30/05
On September 30, 2005, Dudek screened the site for elevated concentrations of lead in
the soil. Dudek used a Niton XLP303A to screen the soil in the backstop, the berms, the
stockpiled soil, and the floor for concentrations of lead. Approximately 250
measurements were taken in situ (on the ground surface, without sample preparation).
Concentrations ranged from less than 50 milligrams per kilogram (mg/kg) to 6,581
mg/kg. The measurement results were used as a screening tool and Dudek recommended
removing small areas of the berm and backstop, in order to remove elevated
concentrations (greater than -500 mg/kg) of lead. The soil in these areas was removed,
as confirmed by additional measurements. Several measurements of the floor contained
elevated concentrations; therefore, Dudek recommended that the majority of the floor be
scraped (to remove a few inches of soil). As the majority of the floor of the shooting
range was previously covered in concrete, it is likely that the floor was inadvertently
contaminated during remediation of the backstop (the contamination was spread out on
the floor).
Soil Sampling -10/13/05
On October 13, 2005, Dudek conducted soil sampling of the floor, the berm, the
backstop, and one remaining soil pile. The soil pile, which contained borderiine
concentrations of lead based on the lead screening, was sampled to determine if the pile
needed to be disposed of as hazardous waste. Dudek collected confirmation soil samples
from the surface of the floor, as the contractor had scraped the floor at least three times.
Additionally, Dudek collected confirmation samples from the backstop and berm, which,
based on the lead screening, did not contain elevated lead concentrations. The samples
collected from the backstop and berm were collected at approximately eye level.
Soil Sampling Results - Total Lead
Dudek collected 18 samples from the floor to be analyzed for total lead by EPA Method
601 OB. Four samples from the stockpile and four from the berm/backstop were also
analyzed for total lead. The 26 samples contained lead at concentrations ranging from 15
mg/kg to 32,000 mg/kg (Figure 1). Four background samples were collected along the
dirt road between the shooting range and Faraday Avenue. The concentration of lead
reported in the background samples was between 3.6 and 8.7 mg/kg.
Soil Sampling Results - SPLP '
In order to determine if the lead in the soil might leach from the soil and contaminate the
groundwater and near-by surface water, Dudek analyzed more than half of the soil
samples for leaching characteristics. The Synthetic Precipitation Leaching Procedure
(SPLP) uses deionized water, adjusted to a pH of 5.0, to simulate leaching that may occur
at the site due to rain. Two of the 17 soil samples contained a detectable concentration of
lead in the leachate (the detection limit was 0.10 milligrams per liter (mg/1). The
concentration of lead in Samples S-10 and S-12 were 0.13 and 0.14 mg/1.
Evaluation of the Results/Recommendations
Based on the sampling results for total lead, the stockpiled soil shown on Figure 1 should
be removed and disposed of as hazardous waste (>1000 mg/kg). Similarly, the majority
of the floor of the shooting range contained concentrations of lead greater than 1000
mg/kg. Dudek recommends that approximately 3 inches of soil be removed from the
floor and disposed of off-site as hazardous waste. The soil should be removed in a way
so as not to contaminate additional portions of the site.
The soil in the backstop and berm and the soil beneath the soil and concrete piles does
not need to be removed. The soil did not contain elevated concentrations of total lead.
Additionally, based on the leaching characteristics, it is unlikely that the lead in the soil
will impact the groundwater and surface water (the concentrations of lead in the leachate
were less than 150 micrograms per liter (ug/1), which is less than the criteria to protect
freshwater aquatic life [Based on the Regional Water Quality Control Board 2003 Water
Quality Goals, a surface water hardness of 1,100 milligrams per liter as CaC03 yields a
lead water quality criteria of over 500 ug/1]).
Based on the previous soil screening, the two small piles near the backstop do not need to
be removed from the site.
