Attention: Mr. Karl Kurka Environmental Program Manager City of Sacramento General Services 915 I Street, 2nd Floor Sacramento, CA 95814

Dear Mr. Kurka,

Reference: Interim Data Report, Mangan Neighborhood Remedial Investigation, City of Sacramento Mangan Pistol and Rifle Range, 2140 34th Avenue, Sacramento, CA

Stantec Consulting Services, Inc. (Stantec) has prepared this Interim Data Report presenting soil data collected from twelve properties in the Mangan Park residential neighborhood located north of the former Mangan Pistol and Rifle Range at 2140 34th Avenue in Sacramento, California (see Figure 1). The work described herein was completed in accordance with the Mangan Neighborhood Remedial Investigation Work Plan (RI Work Plan) prepared by Stantec and dated January 10, 2017, and approved by the County of Sacramento Environmental Management Department (Sacramento EMD) in correspondence dated January 17, 2017.

This report is an interim submittal to facilitate EMD review of the data prior to a scheduled meeting on March 8, 2017. These data will be formally presented with the Remedial Action Plan due to Sacramento EMD by March 20, 2017, as stipulated in the work plan approval letter.

Background

Stantec previously completed incremental soil sampling at 29 properties in the Mangan Park neighborhood, with the objective of identifying properties with elevated mean concentrations of lead that may be attributable to aerial releases from the former gun range. These properties are illustrated on Figure 2, with the exception of site 25, which subsequently opted out of the program (see discussion in following section). Thirteen of the 29 properties reported mean concentrations of total lead in soil (expressed as a 95 percent upper confidence limit on the mean) exceeding the residential soil screening level of 80 milligrams per kilogram (mg/kg). These 13 properties were selected for additional discrete soil sampling to evaluate the distribution of lead in surface soil across each property. At two of the properties (sites 18 and 26), discrete soil samples were collected during the previous round of incremental soil sampling. These data were initially reported in the RI Work Plan, and data from these sites are included in this submittal.

March 3, 2017 Mr. Karl Kurka of 5


Field Activities

The RI Work Plan described systematic grid-based soil sampling at 11 properties. One property owner (site 25, at 5668 Bradd Way) subsequently opted out of the sampling program; therefore, that property was not sampled. The remaining 10 properties were sampled between January 25 and February 2, 2017. Between 28 and 38 samples were collected from each property and analyzed by ESC Lab Sciences for total lead using EPA Method 6010B. Prior to analysis, each sample was sieved using a No. 60 mesh screen (corresponding to 0.250 millimeter [mm] sieve size). In addition, Stantec collected a limited number of bulk paint chip samples from properties where owners granted permission, and where the presence of potential lead-based paint was considered likely to influence the concentration of lead observed in co-located or nearby soil samples. Paint samples were submitted to EMSL Analytical, Inc. (EMSL) for analysis of lead content by flame atomic absorption spectrometry following the EPA SW 846-7000B/7420 analytical protocol. Property-specific sample locations are illustrated on Figures 3-1 through 3-10.

Results

Soil lead results are presented on Figures 3-1 through 3-10, and data from sites 18 and 26 (sampled in October 2016) are presented on Figures 4-1 and 4-2. Descriptive statistics from each property’s data set are summarized in Table 1, and discrete soil lead results and pertinent sampling notes are presented in Tables 2-1 through 2-12. Lead paint data are also depicted on Figures 3-1 through 3-10, and presented with soil data in Tables 2-1 through 2-12.

Preliminary Observations

Our preliminary observations regarding offsite soil data are presented below.

Each of the 12 properties sampled contain concentrations of lead in surface soil exceeding the residential soil screening level of 80 mg/kg. The maximum concentrations of lead observed at each property range from 190 mg/kg to 760 mg/kg.

Elevated concentrations of lead in surface soil generally appear to be distributed across each of the yards, with no discernable pattern of lead distribution across the study area.

Based on the limited number of paint samples collected, there does not appear to be a correlation between lead content in paint and lead concentrations in soil. One or more paint samples were collected from 8 houses, and 5 samples reported the presence of lead-based paint (defined as paint containing lead at 500 parts per million or more by weight). Two properties (sites 9 and 23) had one or more soil samples collected immediately adjacent to lead-based paint, and soil lead results at these locations do not appear to be materially different than concentrations observed elsewhere on the site.



As described in the RI Work Plan, Stantec collected samples from soil beneath rain gutter downspouts, in order to evaluate the presence of lead resulting from rooftop accumulation associated with the former gun range or other aerial sources such as leaded fuel combustion. Concentrations of lead at downspout locations do not appear to be materially different than lead concentrations reported elsewhere on the property, suggesting that significant accumulation of lead dust has not occurred on neighborhood rooftops. Downspout locations are illustrated with sample locations and lead soil data on Figures 3-1 through 3-10.

The AERMOD atmospheric model previously completed by Stantec predicted the highest deposition of lead originating from the gun range in the neighborhood immediately north of 34th Avenue, and that deposition would rapidly attenuate to the north. The lead data set collected to date, including the previous round of incremental sampling, does not correlate with this model, and does not appear to represent lead originating from a point source like the gun range. The distribution of lead likely includes sources not associated with the former gun range, such as aerial deposition from leaded fuel from vehicles and from air traffic associated with Sacramento Executive Airport. A figure depicting the flight paths for Sacramento Executive Airport air traffic is attached for reference.
