The AOC required, in part, groundwater sampling at high and low groundwater elevations, with sampling continuing until two consecutive rounds demonstrate that groundwater meets DEQ-7 standards for PCBs and meets Tier I RBSLs for petroleum hydrocarbons. Groundwater Monitoring On December 22 and 23, 2014, static water levels (SWLs) and groundwater samples were collected from the following nine (9) monitoring wells: MW-10, MW-14, MW-15R, MW-18, MW-19, MW-20 and MW21. Monitoring well MW-11 was measured for light non-aqueous phase liquid (LNAPL) with a bailer to determine if groundwater sample collection was feasible for this well. The bailer displayed a thin (approximately 1/8 inch) layer of free product and was not sampled (Appendix A). Prior to monitoring well sampling, depth to groundwater was measured with a groundwater interface probe. Groundwater samples were collected with a variable rate, low-flow submersible pump. Sample collection was performed when pH readings stabilized to within 0.1 and temperature and conductivity stabilized to within 5% over three casing volumes. Groundwater chemistry was recorded on NewFields groundwater sampling forms. The water samples were collected and preserved with appropriate acid preservative. The samples were submitted under appropriate custody and seals to Energy Laboratory in Billings, Montana for extractable petroleum hydrocarbon screen (EPH-Screen) and polychlorinated biphenyls (PCBs – EPA Method 8082). Results of the water analyses are discussed in Section 3.0, below. Copies of groundwater sampling forms and field activity forms are included as Appendix B. 2.0 SOIL LABORATORY ANALY TICAL RE PORTS The laboratory analytical report for groundwater monitoring is included as Appendix C. 3.0 C ONC LU SIONS AND RECOM ME NDATIONS In December 2014, NewFields completed groundwater monitoring of nine (9) monitoring wells at the Former Stimson Lumber Millsite in Bonner, Montana. An additional monitoring well (MW-11) was measured for LNAPL to determine if groundwater sample collection was feasible for this well. Static water level measurements were collected from monitoring wells on December 22 and 23, 2014. SWL measurements, casing elevations, and groundwater elevations for the ten (10) monitoring wells are given below in Table 1.

LNAPL was present in MW-11 and was measured to be less than 0.01 feet thick using a disposable bailer. Photographs of the bailer containing free product are included as Appendix A.

None of the samples collected from any of the nine (9) wells sampled exceeded DEQ Tier 1 RBSL or WQB-7 standards for groundwater. These results represent the second consecutive round (one at seasonally high groundwater and one at seasonally low groundwater) in which groundwater meets DEQ-7 and Tier 1 RBSL standards. The next groundwater monitoring event is scheduled for June 2015. 4.0 RE FE RE NCE S PBS&J, 2009.

Yes No Not Applicable Standard Reporting Procedures: Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as pH, Dissolved Oxygen and Residual Chlorine, are qualified as being analyzed outside of recommended holding time. Solid/soil samples are reported on a wet weight basis (as received) unless specifically indicated. If moisture corrected, data units are typically noted as –dry. For agricultural and mining soil parameters/characteristics, all samples are dried and ground prior to sample analysis. Contact and Corrective Action Comments: Container temperature for Cooler 1 was 0.6°C, Cooler 2 was 2.2°C and Cooler 3 was 2.6°C. Samples for PCBs taken on 12/22/14 are past the EPA holding time of 7 days, continue with analysis per phone call with Tyler Etzel. Page 24 of 25 Page 25 of 25
