Re: Groundwater Monitoring Report, January 27, 2024

Dear Mr. Gasser:

As requested by DERR, Rockwell Solutions collected groundwater samples at the above-referenced
site on January 27, 2024. Groundwater measurements and samples were collected from monitoring
wells MW-1, MW-3, MW-5, MW-6, MW-7, and MW-8. The wells were sampled using standard
measuring, purging, and sampling procedures.

Groundwater samples were collected from each monitoring well using a disposable bailer. Each
groundwater sample was immediately placed on ice and retained under chain-of-custody
documentation until relinquished to the laboratory. Samples were submitted for analysis of MTBE,
benzene, toluene, ethylbenzene, total xylenes, naphthalene (MBTEXN) and total petroleum
hydrocarbons (TPH) - gasoline range organics (GRO) using EPA Method 8260 and TPH-diesel
range organics (DRO) using EPA Method 8015. Some samples were also analyzed for fractionation
of TPH-GRO and TPH-DRO. Chemtech-Ford conducted the laboratory analyses. Laboratory
reports are attached.

A summary of historical groundwater monitoring data including groundwater elevation and
laboratory analytical data is presented in Table 1 and a groundwater elevation map is presented as
Figure 1. Groundwater elevations decreased an average of 0.88 feet since the last sampling event in
October 2023. Groundwater flow was to the southwest on January 27, 2024.

TPH-GRO and TPH-DRO concentrations exceed Tier 1 levels at MW-5. All other concentrations
in MW-5 and all other monitoring well samples are less than Initial Screening Levels. The
contaminant plume appears to be limited to the area immediately around MW-5.

Rockwell Solutions recommends that release OFV be evaluated for closure based on the limited
extent of contamination and the TPH-GRO and TPH-DRO fractionation results.

Report Footnotes
Abbreviations
ND = Not detected at the corresponding Minimum Reporting Limit (MRL).
1 mg/L = one milligram per liter or 1 mg/kg = one milligram per kilogram = 1 part per million.
1 ug/L = one microgram per liter or 1 ug/kg = one microgram per kilogram = 1 part per billion.
1 ng/L = one nanogram per liter or 1 ng/kg = one nanogram per kilogram = 1 part per trillion.
On calculated parameters, there may be a slight difference between summing the rounded values shown on the report
vs the unrounded values used in the calculation.
