Subject: Second Addendum To "Limited Pliase I Environmental Site Assessment and
Agricultural Chemical Residue Survey, Magnolia Gardens Development, City
ofCarlsbad, San Diego County, California," W.O. E2484-SC, dated March 15,
1999, by GeoSoils, Inc.
Dear Mr. Ferdig:
Pursuant to your request and authorization, GeoSoils, Inc. (GSI) is providing the following
second addendum to the above subject report on the Magnolia Gardens property in
Carlsbad (Establishment No. H 38418). The purpose of this addendum is provide
additional information as requested by the San Diego County Department of Environmental
Health (DEH)-Voluntary Assistance Program in an October 12,1999 DRAFT letter. The
data submitted herein is based upon verbal conversations with Ms. Apecechea (project
manager, DEH Site Assessment and Mitigation Program) in February and March, 2000, as
well as chemical test data collected from hand auger borings (HA-9, HA-10, and HA-11)
drilled on the Magnolia Gardens II parcel (APN 205-220-12) site on March 14, 2000. In
addition, chemical test data was also collected from hand auger borings (HA-8 and HA-12)
excavated through concrete slab core-holes in the two abandoned storage sheds on the
original Magnolia Gardens parcel. All conclusions and recommendations not revised
herein remain applicable, and should be adhered to during remedial earthwork.
SITE DESCRIPTION
Overall, the proposed Magnolia Gardens project (Magnolia Gardens I and II) is located on
the west side of Valley Street, between Magnolia Avenue and Chestnut Avenue in the city
of Carlsbad. Magnolia Gardens II, added to the proposed development after our initial
residue survey (GSI, 1999b), consists of a ±1.8-acre parcel (APN 205-220-12) situated
directly north of Magnolia Gardens I (Carlsbad Tract CT-98-12). The rectangular-shaped
land is relatively level, sloping gently to the west. Elevations onsite range from
approximately 175 feet Mean Sea Level (MSL) along Valley Street (east side of Lot 6), to
roughly 154 feet MSL along the western edge of Lot 1 (Plate 1). Active greenhouses
(containing flowers) currently exist onsite. Irrigation lines are present within the site, along
with storage facilities at the east end and temporary living quarters for workers and various
parked personal vehicles on the west end of the property.
PROPOSED DEVELOPMENT
Based upon the tentative map for Magnolia Gardens II (Ladwig Design, 2000), the
proposed development will consist of site preparation for the construction of six additional
single family residential lots (Lots 1 through 6) and street improvements. Street "B"
separates Magnolia Gardens I from II. It is our understanding that the proposed structures
would consist of one and/or two-story buildings, with continuous footings, and slabs-on-
grade, utilizing wood-frame construction. Typical public underground utilities are planned.
Cut and fill grading techniques are anticipated to be used to develop building sites for the
planned structures and roadways.
SCOPE OF WORK
As requested by DEH, GSI is providing the following information on the proposed Magnolia
Gardens i and II residential project, as it relates to the above referenced Limited Phase I
Environmental Site Assessment (ESA) and Agricultural Chemical Residue Survey by this
office (GSI, 1999b). This current phase of soil sampling and chemical testing was
completed within the Magnolia Gardens II property and in the two pesticide storage areas
within the initial Magnolia Gardens parcel.
The soil sampling and chemical testing completed for this phase of our evaluation within
the Magnolia Gardens property as a whole consisted of ten (10) additional soil samples
collected onsite on March 14,2000. The 1.8± acres which comprise Magnolia Gardens II
was divided into a three equal sections, with two (2) samples collected within each grid.
Soil samples HA-9, HA-10, and HA-11 were collected from a depth of Vz foot and V/2 feet
at a random location within each grid. Specifically, samples HA-9 and HA-10 were
collected within cultivated flowers beds. Sample HA-11 was collected from the vicinity of
a temporary, wooden chemical storage shed. Samples HA-8 and HA-12 were collected
from beneath the concrete slabs in the two abandoned chemical storage areas reported
previously. Core holes were drilled through the slabs on March 8, 2000.
Holes were excavated using a four (4) inch diameter hand auger. The stainless steel hand
auger was washed in a tri-sodium phosphate (TSP) solution and rinsed with clear water.
The auger was final rinsed with distilled water prior to each test hole. Soils encountered
in our holes consisted of dry to moist, loose to medium dense, red brown to brown silty
sands and clayey sands. Samples were collected, stored and transported to a California
Department of Health Services (DHS) certified laboratory the same day, following proper

protocol procedures. A Chain-of-Custody document, recorded with the laboratory, is
included in Appendix B. Sample locations are provided on Plate 1.
Based upon the County of San Diego DEH protocol, the chemical laboratory conducted
discrete chemical analysis of the samples. Chemical testing included the following
substances:
• Soil samples tested for Chlorinated Pesticides and PCB's, utilizing EPA test method
8080.
• Soil samples tested for Organophosphorous Pesticides, utilizing EPA test method
8140.
Soil samples tested for Chlorinated Herbicides, utilizing EPA test method 8150.
GSI requested the chemical laboratory to test all samples collected from the Vz-foot interval
individually for the three suites of chemical tests presented above. Initially, samples
collected from the IVa-foot interval would be tested for contaminants by EPA test method
8080 only. These samples were archived for additional discrete testing in the event the Va-
foot interval samples detect "high" concentrations of contaminants from the other two
suites of test methods (i.e., EPA test methods 8140 and 8150). This testing format typically
allows for detection of individual contaminants, eliminating needless repetition. Based
upon laboratory test results, further testing was completed on the 1 Vz-foot interval by EPA
test method 8080 only.
CHEMICAL TEST RESULTS
Based upon the laboratory test results, there were no chemical constituents detected in
the EPA 8140 test method suite. From the EPA 8080 test method suite, concentrations of
DDT/DDD/DDE (i.e., DDTfr^^tai)) were detected in nine (9) ofthe ten (10) samples collected,
and Heptachlor Epoxide was detected in one (1) sample. Concentrations of DDTfj^otai) were
reported to range from "less than detection limits" to 0.6125 milligrams per kilogram (i.e.,
mg/kg). For comparison purposes, regulatory action levels for hazardous waste criteria
(i.e.. Total Limit Threshold Concentration) for DDT(Totai) is 1.0 mg/kg. All sample
concentrations decreased with depth. Heptachlor Epoxide was detected at a
concentration of 0.0005 mg/kg in sample HA-8 at Vz a foot.
From the EPA 8150 test method suite, 2,4,5-T was detected in three (3) samples and 2,4-
DB was detected in one (1) sample. Concentrations of 2,4,5-T was reported to range from
"less than detection limits" to 0.0064 mg/kg. 2,4-DB was detected at a concentration of
0.0089 mg/kg.

Residue concentrations of DDTgoja,, Heptachlor Epoxide, 2,4,5-T, and 2,4-DB detected in
soil samples were compared to the Preliminary Remedial Goals (PRGs) for residential soil
concentrations (Smucker, 1999). PRG tables combine existing USEPA toxicity values with
generally accepted exposure factors to estimate concentrations in soil that do not
represent a cancer risk to humans greater than one-in-one million (i.e., 1 x 10"^). Exposure
pathways considered include ingestion, inhalation and dermal absorption. Chemical
concentrations presented in the PRG tables, therefore, can be directly compared to the
residue concentrations detected in soils within the property. The PRG tables may be used
initially in lieu of a health based risk assessment to determine the need for further
evaluation of sites with concentrations of known cancer-causing contaminants (i.e., site
screening).
Provided below (Table 1) are test results, as well as criteria limits for the preliminary
estimate of risk to human health (i.e.. Preliminary Remedial Goals). Test results are
provided in Appendix B.

It should be noted that human health based risk concentration levels, which are typically
lower than hazardous waste criteria concentrations, will likely be the default factor
regarding the depth and amount of remedial grading needed to mitigate concentrations
of pesticide residues detected onsite. Remedial grading may include (but not limited to)
removal and burial of impacted earth materials at locations and depths with which will
effectively eliminate future human contact, as well as eliminate potential impacts to surface
water and groundwater. Guidelines for remedial earthwork are discussed in detail in the
referenced reports.
CONCLUSIONS and RECOMMENDATIONS
Conclusions
Based upon the information obtained during the course ofthis study, as well as information
provided in the referenced texts, GSI presents the following summary of findings,
conclusions, and recommendations:
Agricultural chemical residues detected within near-surface earth materials on the
Magnolia Gardens project are consistent with our experience with similar farmlands
in San Diego County, in that the majority of contaminants detected fall within the
Chlorinated Pesticides suite (EPA test method 8080). This suite of contaminants are
known for their persistence in nature.
Except for DDT, DDD, DDE (i.e., DDT^^) and Heptachlor Epoxide, no constituents
of the Chlorinated Pesticides and PCB's suite were reported above the laboratory
detection limits (i.e., non-detect). Concentrations of 007^^^^,^ (0.004 mg/kg to
0.6125 mg/kg) were detected in nine (9) of the ten (10) samples collected.
Heptachlor Eoxide was detected in only one sample (HA-8) collected from the Vz-
foot interval, at a concentration of 0.005 mg/kg. Data collected Indicate that
concentrations of pesticides detected decrease with depth. Chemical laboratory
test results are presented in Appendix B.
There were no constituents detected above the laboratory test reporting limits for
Organphosphorous Pesticides suite (EPA test method 8140) in sample collected
from the Va-foot Interval. Based upon these results, samples from the IVa-foot
interval were not tested. Chemical laboratory test results are presented in
Appendix B.
Based upon test results from the Chlorinated Herbicides suite (EPA test method
8150), 2,4,5-T was detected in three (3) ofthe five (5) samples collected from the
y2-foot interval on the subject site, at concentrations ranging from 0.0034 mg/kg to
0.0064 mg/kg. 2,4-DB was detected in one (1) of the five (5) samples collected
from the Vs-foot interval, at a concentration of 0.0089 mg/kg. Based upon the

limited nature of the reported test results, samples from the 1 Va-foot interval were
not tested. Chemical laboratory test results are presented in Appendix B.
• Where applicable, GSI has used existing regulatory data as a screening tool for the
detected concentrations of pesticides and other contaminants within the property.
Specifically, GSI utilized Preliminary Remedial Goals (PRGs), which combine
existing USEPA and CALEPA (where available) toxicity values with generally
accepted exposure factors to estimate concentrations in residential-use soil that do
not represent a cancer risk to humans greater than one-in-one million (i.e., 1 x lO"^).
• Preliminary Remedial Goals, which combine existing USEPA toxicity values with
generally accepted exposure factors to estimate concentrations in residential soil
that do not represent a cancer risk to humans greater than one-in-one million (i.e.,
1 X 10'^), are 1.7 mg/kg for DDT, 0.053 mg/kg for Heptachlor Epoxide, 490 mg/kg
for 2,4-DB, and 610 mg/kg for 2,4,5-T.
• The regulatory action levels for hazardous waste criteria (Total Threshold Limit
Concentration-TTLC), the Preliminary Remediation Goals (PRGs) for chemical
residues (detected and non-detected onsite), and the chemical laboratory detection
limits (presented in Appendix B) were compared. In summary, detection limits
utilized by the testing laboratory were overall at least an order of magnitude (i.e.,
lOx) below PRG levels for all constituents except PCBs, which were at least 4x
below the TTLC and PRG levels. It should be noted that TTLC levels were not
readily available for all analyses tested; however, based upon the majority of readily
available regulatory levels, it appears likely that detection limits utilized by the
laboratory are suitable for agricultural-use chemicals.
• Based upon the relatively low concentrations of agricultural chemical residues
reported herein, it appears that agricultural operations on the property have not
generated significant agricultural chemical residues on the subject property. It is
our opinion, therefore, that the initial survey report recommendations remain
applicable. The Client should understand that this report will be reviewed by the
San Diego County Department of Environmental Health Services. Typically, action
levels for soil are based upon site specific regulatory agency guidance, which is
known to vary from site to site based upon actual site conditions. Actual mitigation
requirements (if any) will be based upon their review comments.
Recommendations
Data submitted herein is consistent with conclusions and recommendations provided in
the initial report. Based upon the information collected by GSI during this environmental
evaluation, further studies or action, other than the recommendations provided in the initial
survey report (dated March 15,1999), are not proposed from an environmental viewpoint,
at this time.
