RE: Geoprobe and Soil Sampling Services Naval Submarine Base New London Fuel Farm

Groton, CT 06340 KEC Job #: 19(GP)104

Dear Ms. Silvestri, Kropp Environmental Contractors, Inc. (KEC) is pleased to present this letter report documenting Geoprobe and soil sampling services at the above referenced address in Groton Connecticut.

Summary of Field Investigations

On January 11, 2019, KEC advanced one (1) soil boring to 15.75 feet below ground surface (bgs) between the transformer and the oil-water separator (OWS) in the area referred to as the fuel farm, as directed by naval personnel, using a Geoprobe® model 7822DT direct push drill rig.

Two (2) soil samples were collected from the boring at depths of 4 feet bgs (Sample S-1) and 7.3 feet bgs (Sample S-2), respectively. The soil boring was converted into a 2-inch temporary groundwater monitoring well. Groundwater was encountered in the temporary well at around 7.3 feet bgs. KEC collected a grab groundwater sample from the well and submitted it, along with the two (2) soil samples, to Phoenix Environmental Laboratories, Inc. (Phoenix) in Manchester, Connecticut for analysis for extractable total petroleum hydrocarbons (ETPH) by the Connecticut ETPH Method. The groundwater sample was also analyzed for semi-volatile organic compounds (SVOCs) (polycyclic aromatic hydrocarbons [PAHs] only) via Environmental Protection Agency (EPA) Method 8270 and Soil Sample S-2 was also analyzed for PAHs and volatile organic compounds (VOCs) via EPA Method 8260.

No diesel fuel constituents were detected at concentrations above the laboratory method reporting limits (MRLs) in any of the samples. The analytical results are summarized in Table 1 and 2, and the laboratory report is presented in Attachment I.

SDG Comments 8270 Semi-volatile Organics CC28457, CC28458:

The client requested a short list for 8270 RCP Semivolatile. Only the PAH constituents are reported as requested on the chain-of-custody.

8270 Semi-volatile Organics by SIM CC28458:

Poor surrogate recovery was observed for one acid and/or one base surrogate. The other surrogates associated with this sample were within QA/QC criteria. No significant bias suspected.

ETPH Narration Were all QA/QC performance criteria specified in the Reasonable Confidence Protocol documents achieved? Yes.

QC Batch 463578 (Samples: CC28457): -----

The LCS/LCSD RPD exceeds the method criteria for one or more analytes, but these analytes were not reported in the sample(s) so no variability is suspected. (Benzo(a)pyrene, Benzo(b)fluoranthene, Benzo(ghi)perylene, Chrysene, Dibenz(a,h)anthracene, Indeno(1,2,3-cd)pyrene)

The LCS/LCSD RPD exceeds the method criteria for one or more surrogates, therefore there may be variability in the reported result. (% 2-Fluorobiphenyl, % Terphenyl-d14)
