Environmental Testing on Soil and Ground Water Samples

On January 11, 2005, Ms. Kathryn Sheridan, Project Scientist, and Mr. Joseph Levinson, 

Staff Scientist with Schnabel, performed three hand augers (EB-1 through EB-3) on the subject 

property. The approximate hand auger locations are provided on Figure 2. 

1.1 PID Screening

Soil samples obtained during the hand auger activities were screened with a 

Photoionization Detector (PID) by Ms. Sheridan. The PID is an instrument used to detect 

volatile organic compounds (VOCs). The screening was performed as a headspace analysis of 

soil samples retained in glass jars. No elevated PID measurements were obtained from the soil 

samples obtained from the hand augers. Note that a PID reading is a measure of the VOCs 

present in the sample and are not a direct measure of the quantity of total petroleum 

hydrocarbons (TPH) present in the soil sample. In addition, a PID may not detect older and 

heavier fuel patterns, as the volatiles in such substances may no longer be present due to the 

passage of time of the nature and/or composition of the fuel type. 

1.2 Analytical Soil Test Results

Selected soil samples from each hand auger location were submitted to an EPA-approved 

laboratory, Phase Separation Science, Inc., for chemical analysis for the analytical parameters 

listed below. The chain of custody forms and laboratory test results are attached. 

• Total Petroleum Hydrocarbons – diesel and gasoline range organics (TPH-DRO/GRO), 

• TPH-1664, which detects and measures heavier and older fuel patterns not detected 

within the DRO/GRO ranges, 

• Polychlorinated Biphenyls (PCBs), 

• Semi-volatile Organic Compounds (SVOCs), 

• Volatile Organic Compounds (VOCs); 

• Organochlorine Pesticides, and 

• Priority Pollutant Metals, which include antimony, arsenic, beryllium, cadmium, 

chromium, copper, lead, mercury, nickel, selenium, silver, thallium, and zinc. 

Based on the laboratory test results, all of the soil pesticides, PCBs, SVOCs, VOCs, and 

TPH test results were below their respective practical quantitation limits (PQLs), or below the 
Schnabel Engineering North, LLC

laboratory detection limits, with the exception of methylene chloride, which was detected in one 

sample from EB-1 at its PQL. Since methylene chloride was also detected in a laboratory blank 

sample, it is considered to be a laboratory contaminant that may be a residual chemical left in the 

testing equipment. 

For the priority pollutant metals tested, elevated test results (above PQLs) for arsenic, 

chromium, copper, lead, mercury, nickel, and zinc were obtained. Table 1 presents a summary 

of the priority pollutant metal results that were detected above laboratory PQLs. Note that the 

final column of Table 1 presents the Federal Environmental Protection Agency’s (EPA’s) RiskBased Concentrations (RBCs) for Region III industrial soils.

Zinc (mg/kg) 98 54 54 610,000 

mg/kg = milligrams per kilogram NE = not established ND = not detected 

Review of the metal test results obtained at the site indicates that the metal results are 

below established EPA’s RBC levels for industrial soils, with the exception of arsenic at all three 

hand auger locations. The EPA does not have established RBC levels for mercury or lead; 

however, the EPA recommends using an action level of 400 ppm (parts per million) for lead in 

soil. All lead test results were below this recommended action level for lead. 

It should also be noted that heavy metals, such as arsenic, lead, and mercury, are also 

naturally occurring elements. Table 2 presents a summary of the arsenic, lead, and mercury 

results, as well as the common ranges for these metals in soils in the eastern United States. 

Based on Table 2, the site’s arsenic, lead, and mercury levels are within their naturally occurring 

ranges.

Additionally, the Federal Register (1990) provides regulatory level concentrations for 

these three metals that are a standard, based on leaching capabilities, for which a substance is 

considered hazardous. The Federal Register’s regulatory levels for these metals are also 

included in Table 2. The regulatory levels are for soils that have been diluted to a ratio of one 

part soil to 20 parts water, as part of the leaching test procedure. Based on this, and assuming 

100 percent leaching of the samples tested (a conservative assumption), the metal test results for 

arsenic, lead, and mercury can be divided by a factor of 20 for direct comparison with the 

Federal Register’s levels. This analysis was performed on these three metals and indicated that, 

based on this method of comparison, none of the soil samples are considered hazardous for the 

metals indicated in Table 2. 

1.3 Analytical Water Test Results

One water sample from each hand auger location was submitted to the laboratory for 

chemical analysis for the analytical parameters listed below. The chain of custody forms and 

laboratory test results are attached. 

• TPH-DRO/GRO, 

• TPH-1664, 

• PCBs, 

• SVOCs, 

• VOCs; 

• Organochlorine Pesticides, and 

• Priority Pollutant Metals. 

Based on the laboratory test results, all of the water pesticides, PCB, SVOC, and TPH 

test results were below their respective PQLs, or laboratory detection limits. Note that an 

estimated level of the SVOC di-n-butyl phthalate of 2 ug/L was provided by the laboratory for 

the water sample from EB-1, but this value is still below the PQL. In addition, the water sample 
Schnabel Engineering North, LLC

from EB-2 had a chloroform level of 1 ug/L, which is just at the PQL. Table 3 compares this 

value to two regulatory limits, one of which the site’s result exceeds. However, the regulatory 

limit is based on ingestion risks, and the site is planned to be supplied with public water.

For the priority pollutant metals tested, elevated test results above PQLs for arsenic, 

chromium, copper, lead, nickel, and zinc were obtained. Table 4 presents a summary of the 

priority pollutant metal results that were detected above laboratory PQLs and related regulatory 

limits.

Review of the water metal test results obtained at the site indicates that the only arsenic 

and lead results were above established regulatory limits. The lead result for EB-3 is above the 

EPA’s Drinking Water Standard, and the arsenic levels at EB-1 and EB-3 exceeded the EPA’s 

RBC for tap water. In addition, the arsenic result for EB-1 also exceeded the EPA’s Drinking 

Water Standard. Again, the water tested at the site is not planned to be used for consumption 

purposes by humans, for which the regulatory limits exceeded were developed.
