Subject: Soil Sample Results for 16835 Baseline Avenue and Adjacent Parcels, Fontana
Dear Mr. Hosseinioun:
PlaceWorks, on behalf of Abolfath Hosseinioun (Client), submits this letter report to document the soil
sampling program implemented at the Baseline Parcels located at 16835 Baseline Avenue, Fontana, San
Bernardino County, California (Figures 1 and2). The project site consists of 6.59-acres (site) located to the
west of the intersection of Baseline Avenue and Sierra Avenue at 16835 Baseline Avenue in Fontana, San
Bernardino County.
The site is divided into two areas, Area A is approximately 1.12-acres and consists of Assessor Parcel
Number [APN] 0241-051-16 and has the address 16835 Baseline Avenue. Area B consists of the following
four adjacent parcels to Area A: APNS 0241-051-17, 0241-051-01, 0241-051-02, and 0241-051-32. Figure 3
shows the parcels and APNs labeled on Area A and B.
A Phase I Environmental Site Assessment was implemented for Area A in May 2018 that identified one
Recognized Environmental Condition (REC) for the Area A parcel. Area A was used as an orchard with a
residence from at least 1938 to approximately 1960 when the orchard was no longer present. The site
was an orchard during the time period when organochlorine pesticides were used to protect crops.
Limited soil sampling for organochlorine pesticides and arsenic was recommended. PlaceWorks was
requested to also assess Area B for potential residual pesticides due to the historic land use of Area B
which included an orchard, a chicken farm and residential.
Both Areas A and B are currently vacant undeveloped disturbed land with no structures located on the
site. The site is bounded by Baseline Avenue to the north, Sierra Avenue to the east, and Montgomery
Avenue to the south. Surrounding the site is a mixture of vacant land, residential and commercial office
uses. New houses are located to the north across Baseline Avenue, a senior citizen villa is located to the
northeast, an Arco Service Station is located to the east across Sierra Avenue, and adjacent land to the
south and west is vacant. The nearest school is Kathy Binks Elementary School, located approximately 0.5-
mile to the west off Baseline Avenue.
SUMMARY OF FIELD ACTIVITIES
Soil samples were collected following protocols described in the Department of Toxic Substances Control
(DTSC)’s PEA Guidance Manual (DTSC 2015).
Soil samples were collected on July 23, 2018 within the approximately 6.59 acre project area. Three soil
samples were collected from the soil surface at 0.5 feet below ground surface (bgs) in Area A and nine soil
samples were collected 0.5 feet bgs from Area B. Soil sample locations are shown on Figure 4. Soil
sampling was conducted using a hand auger. Soil from the hand auger barrel was emptied into a certified
pre-cleaned glass jar, then sealed and labeled. Observations pertaining to the soil type were described by
August 6, 2018 | Page 2
the field geologist. Each soil sample was labeled with the sample number, sample depth, and the date and
time the sample was collected. Samples were immediately placed in an ice-filled cooler and listed on a
chain-of-custody form. Any observation pertaining to potential soil contamination or soil source was
recorded. The chain-of-custody form is included as an attachment.
Area A
One composite soil sample and one discrete soil sample was analyzed for organochlorine pesticides by
EPA Method 8081A in Area A to assess historic use of pesticides related to the agricultural land use of the
site and also for residual termiticides from the historic structures.
Two surface soil samples were analyzed for arsenic to assess for potential residual arsenic based
pesticides and three surface samples were analyzed for lead to assess potential lead-based paint impacts
to soil from former structures by EPA Method 6010B. The soil samples were analyzed using A&R
Laboratories, a California State Certified Laboratory.
Area B
Four composite samples and one discrete soil sample was analyzed for organochlorine pesticides from
Area B to assess historic use of pesticides related to the agricultural land use of the site and also for
residual termiticides from the historic structures.
Five surface soil samples were analyzed for arsenic to assess the historical agricultural land use of Area B
and nine soil samples were analyzed for lead to assess historic structures. The laboratory analytical report
for Area A and B is included as an attachment.
FINDINGS
No odors or staining were observed by the field geologist. Groundwater was not encountered. Soils at the
site were gravelly sandy loam.
Pesticides
Area A
Two organochlorine pesticides were reported in the soil samples analyzed from Area A: 4,4`-DDE and 4,4`-
DDT. The concentrations were not elevated above health based screening levels for industrial land use
exposure and residential land use exposure scenarios. The concentrations were screened against
Department of Toxic Substances Control (DTSC) Screening Levels and EPA Region 9 Regional Screening
Levels for discrete soil samples and also adjusted for 2:1 composite samples. Table 1 is a summary table of
pesticide results at Area A.
4,4`-DDE was detected with concentrations ranging from 0.012 milligram per kilogram (mg/kg) to 0.038
mg/kg. All concentrations of 4,4`-DDE were significantly below the EPA Region 9 Regional Screening levels
of 2 mg/kg for 4,4`-DDE and 2:1 composite screening level of 1 mg/kg.
4,4`-DDT was detected with concentrations ranging from 0.0025 mg/kg to 0.017 mg/kg. All concentrations
of 4,4`-DDT were significantly below the EPA Region 9 Regional Screening levels of 1.9 mg/kg for 4,4`-DDT
and 2:1 composite screening level of 0.95 mg/kg.
August 6, 2018 | Page 3
Area B
Four organochlorine pesticides were reported in the soil samples analyzed from Area B: chlordane, 4,4`-
DDE,4,4`-DDT and dieldrin. The concentrations were not elevated above health based screening levels for
industrial land use exposure and residential land use exposure scenarios. The concentrations were
screened against Department of Toxic Substances Control (DTSC) Screening Levels and EPA Region 9
Regional Screening Levels for discrete soil samples and also adjusted for 2:1 composite samples. Table 2 is
a summary table of pesticide results at Area B.
Chlordane was detected in one composite sample B-9, B-10 at 0.044 milligrams per kilogram (mg/kg),
which is below the DTSC Screening Level of 0.22 mg/kg for 2:1 composites for chlordane and below the
EPA Region 9 RSL of 0.85 mg/kg.
4,4`-DDE was detected in all soil samples with concentrations ranging from 0.0021mg/kg to 0.024 mg/kg.
All concentrations of 4,4`-DDE were significantly below the EPA Region 9 Regional Screening levels of 2
mg/kg for 4,4`-DDE and 2:1 composite screening level of 1 mg/kg.
4,4`-DDT was detected with concentrations ranging from 0.0096 mg/kg to 0.022 mg/kg. All concentrations
of 4,4`-DDT were significantly below the EPA Region 9 Regional Screening levels of 1.9 mg/kg for 4,4`-DDT
and 2:1 composite screening level of 0.95 mg/kg.
Dieldrin was detected in one composite sample B-9, B-10 at 0.013 mg/kg, which is below the EPA Region 9
Regional Screening levels of 0.017 mg/kg for 2:1 composite samples.
Arsenic
Area A
Arsenic was detected in two surface soil samples analyzed ranging in concentration from 2.64 mg/kg to
2.73 mg/kg. The arsenic concentrations are within background naturally occurring concentrations in
native soil and are below the DTSC’s screening level of 12 mg/kg for arsenic. Table 3 is a summary table
showing arsenic concentrations in soil in Area A.
Area B
Arsenic was detected in four surface soil samples analyzed ranging in concentration from 1.12 mg/kg to
3.03 mg/kg. The arsenic concentrations are within background naturally occurring concentrations in
native soil and are below the DTSC’s screening level of 12 mg/kg for arsenic. Table 4 is a summary table
showing arsenic concentrations in soil in Area B.
Lead
Area A
Lead was detected in the three surface soil samples analyzed from Area A ranging in concentrations from
19.4 mg/kg to 56.8 mg/kg. The lead concentrations are below DTSC Screening Levels for both residential
and industrial land use exposure scenarios. Table 3 includes lead results for soil samples collected from
Area A.
August 6, 2018 | Page 4
Area B
Lead was detected in nine surface samples collected in Area B ranging in concentration from 10.6 mg/kg
to 164 mg/kg. Two surface soil samples, B-7 and B-11, are above the DTSC’s health based screening level
of 80 mg/kg for lead for residential land use; however, the average lead concentration for the site was 48
mg/kg which is below the DTSC screening level for residential exposure. The DTSC screening level for
industrial exposure is 320 mg/kg which was not exceeded for the site. Table 4 includes lead results for soil
samples collected from Area B.
CONCLUSIONS AND RECOMMENDATIONS
Based on the analytical results for organochlorine pesticides, lead and arsenic; no potential health-based
risks were identified based on the historic land use at the site of agricultural use. PlaceWorks
recommends that no further soil analysis is needed to assess the impacts of the historic agricultural usage
of both Site A and Site B.
