1 March 28, 2017 Attn: Mr. Michael Lee Code Enforcement Officer Town of Denmark 62 East Main Street Denmark, Maine Subject: February 2017 Monthly Monitoring Report Poland Spring Bottling Company Cold Spring (Site): Denmark, Maine Dear Mr. Lee: In accordance with the Town of Denmark Permit for Water Extraction from Cold Spring in Denmark, Maine (the Permit), Amec Foster Wheeler Environment & Infrastructure, Inc. (Amec Foster Wheeler) has prepared the attached February 2017 Monthly Monitoring Report on behalf of the Poland Spring Bottling Company. Water withdrawal for bottling purposes began on June 1, 2010 at the Cold Spring site. This monthly report includes the following information required by the noted conditions of the Permit: Borehole #1 and # 2 monitoring data (Schedule A1); Groundwater levels from onsite monitoring wells, and PZ-01 (Schedule A2); Surface water levels from onsite staff gauges (Schedule A4); Stream flow from two locations along Beaver Brook (Schedule A5); Water levels and flow from onsite spring points (Schedule A6); Precipitation information (Schedule A7); Biological monitoring information (Schedule A8); and Action Levels and Responses (Schedule B). Unless otherwise noted, these field data were collected on February 28, BOREHOLE MONITORING In total, the volume of water withdrawn by Boreholes # 1 and # 2 between February 1 st and 28 th was 6,544,750 gallons. Weekly borehole production volumes for the February time period of January 29 through March 4, 2017 are presented in Appendix A. The aggregate pumping rate from Boreholes # 1 and # 2 for this period was less than the short term maximum rate of 300 gallons per minute (gpm) and less than the average weekly rate of 200 gpm. The weekly extraction rates are shown in Appendix A. Each tanker of water is tested for turbidity by Poland Spring personnel at the receiving bottling plants. Turbidity readings were below 0.5 Nephelometric Turbidity Units (NTU) for the month of February. Water samples were collected for odor analysis on August 5, 2009, February 16, 2010, February 15, 2011, January 12, 2012, January 31, 2013, January 8, 2014, February 18, 2015, and February 8, Odor was detected in the February 2011, January 2014, and February 2015 water samples collected from Borehole # 2, and the January 2012, January 2014, and February 2015 water samples collected from Borehole # 1. Odor was detected in these samples Correspondence: Amec Foster Wheeler 511 Congress Street, Suite 200 Portland, Maine Tel Page 1 of 6 Fax

Water quality monitoring was conducted in December 2009, March 2010, November 2010, June 2012, and June 2013; approximately four months prior to beginning water withdrawal, one month prior to beginning water withdrawal, 6 months after startup, two years after startup, and three years after startup respectively, as required by Schedule A, Section 3 of the Permit. Letters and analytical reports were sent to the property owners who have taken part in Poland Spring s domestic monitoring program. A copy of these materials was also sent to the Town Manager and the Town consultant. Based on monitoring to date, there have not been adverse impacts to domestic wells as a result of water withdrawal by Poland Spring. Page 2 of 6

The higher flow at the upstream location compared to the downstream Dam location is consistent with the bankfull conditions observed at the upstream location at the time of monitoring. In addition, above freezing average temperatures were recorded for six days prior to February 28, including four day time high temperatures above 50 degrees. It is also expected that some of the flow was stored within the stream banks along the approximate 1.5 mile length of Beaver Brook between the upstream and downstream Dam location. Subsequent to the February monitoring event, it has been measured in March that flow volumes downstream and upstream on Beaver Brook have since returned to typical conditions demonstrating higher flow downstream relative to upstream. The following graph summarizes the downstream gauging results at the Rocky Knoll Road Dam since February The naturally occurring fluctuations shown in the graph below are expected to continue during site operation.

WETLAND MONITORING (PLANT SPECIES) Stantec Consulting conducted biological monitoring during August This represents the seventh year of long-term wetland biomonitoring at the Cold Spring site. The results of the 2016 monitoring are included as Appendix C. Stantec Consulting concludes that the data collected to date continue to demonstrate that Poland Spring s operations have not had an adverse impact on wetland vegetation or hydrology. ACTION LEVELS AND RESPONSES Pumping Rates As summarized above, water withdrawal did not exceed the average and maximum pumping rates established for the site. Therefore, weekly monitoring and reporting was not required. Monitoring Wells The water level measured at MW-16 was ft amsl. This elevation is greater than the alert level of ft amsl and action level of ft amsl. No response actions were required. Spring Points Water levels were above the ground surface during this monitoring period. Spring point water elevations were greater than the alert level of one foot above the ground surface. Therefore, no response actions were required. Stream Flow The stream flow measured at the Rocky Knoll Road Dam was 9.84 cfs. This flow is greater than the alert level of 0.48 cfs and action level of 0.40 cfs. Therefore, no response actions were required. Domestic Wells No response actions were required. Page 5 of 6

12 COLD SPRING 2016 LONG-TERM BIOLOGICAL MONITORING REPORT, DENMARK, MAINE Introduction 1.0 INTRODUCTION Nestle Waters North America Inc. (Poland Spring) has been authorized by the Town of Denmark and the Maine Department of Environmental Protection (MDEP) Order Number L GW-A-N to withdraw groundwater through two production boreholes at Cold Spring in Denmark, Maine (Figure 1). Poland Spring initiated groundwater withdrawals at Cold Spring in Cold Spring is located east of the intersection of Rocky Knoll Drive and Cold Spring Drive. The boreholes are associated with a freshwater wetland complex and Beaver Brook, which flows east to west through the wetland complex into Holts Mill Pond. In 2005, Woodlot Alternatives, Inc. (now Stantec Consulting Services Inc. [Stantec]) initiated biological monitoring (biomonitoring) to establish baseline ecological conditions within the wetlands at the Cold Spring site prior to Poland Spring s withdrawal of spring water. Through correspondence with the MDEP and Poland Spring, Stantec outlined biomonitoring methodology in the Nestle Waters North America Inc. Cold Spring, Denmark, Maine: Baseline and Long-term Biological Monitoring Plan (hereafter, biomonitoring plan). The purpose of the biomonitoring plan was to monitor for potential shifts in wetland structure and community composition relative to baseline conditions that might result from water withdrawal. This plan included the installation and annual monitoring of three plots within the wetland associated with the boreholes and three reference plots in a wetland beyond the influence of the boreholes. In 2008, Stantec finalized a biomonitoring plan for groundwater withdrawal at Cold Spring, which was approved by the MDEP as required by the Maine Natural Resources Protection Act permit. A copy of the biomonitoring plan was also sent to the Town of Denmark. Stantec completed baseline biomonitoring within the wetlands in 2005, 2006, 2007, and 2009, as well as long-term monitoring in 2010 through The results of these biomonitoring efforts have been previously reported to the Town of Denmark (Appendix A). Long-term biomonitoring was initiated in 2010 subsequent to the commencement of groundwater withdrawal operations and continued annually through This report presents the results of the seventh year of long-term biomonitoring activities that was completed in WETLAND BIOMONITORING METHODOLOGY In 2016, biomonitoring was conducted at the wetland communities associated with the Cold Spring site and at the reference locations. The biomonitoring was conducted in accordance with the methodology outlined in the biomonitoring plan and as required by Condition of Approval A6 of the Town of Denmark selectmen s permit issued to Poland Spring for its use of Cold Spring. On August 10, 2016, Stantec conducted biomonitoring within the three 5-meter by 5-meter monitoring plots in the forested wetland adjacent to the borehole locations. Stantec also 1

13 COLD SPRING 2016 LONG-TERM BIOLOGICAL MONITORING REPORT, DENMARK, MAINE 2016 Wetland Biomonitoring Results conducted biomonitoring at the three reference plots established in the forested wetland outside of the influence of the boreholes (Figure 2). Amec Foster Wheeler hydrogeologists measured groundwater levels in April through October at shallow piezometers associated with each biomonitoring plot WETLAND BIOMONITORING RESULTS The 2016 biomonitoring activities were completed subsequent to the initiation of groundwater withdrawal operations. Completed vegetation plot data forms are presented in Appendix B and provide information on plant species present, estimated areal cover, and the corresponding wetland rating according to the National List of Plant Species that Occur in Wetlands. 1,2 For each monitoring plot, total percent cover, total species, and percent of hydrophytes (i.e., wetland plants) were calculated. In addition, the data forms present hydrologic indicators. Piezometer data, including water levels and piezometer elevations for each monitoring plot, are presented in Appendix C. Appendix C also includes graphs showing monthly water level fluctuations for each wetland piezometer between April and October. Appendix D presents representative monitoring plot photographs. As reported during the 2009 biomonitoring, beaver (Castor canadensis) activity resulted in inundation and subsequent dieback of the forested wetland vegetation and increased canopy openings associated with the monitoring plots, particularly plot MP-2. Beaver inundation occurred in the vicinity of the monitoring plots in spring 2014 but was limited in duration and did not appear to cause dieback or additional declines or changes in wetland vegetation. The forested wetland community continues to regenerate and undergo natural changes in vegetation diversity and abundance, although species dominance is different from baseline conditions. Section 4.0 below further discusses the changes of the monitoring plots compared to previous monitoring years BIOMONITORING RESULTS COMPARISON WITH BASELINE DATA 4.1 VEGETATION MONITORING Appendix E includes a comparison of the vegetation data collected in 2016 to baseline data collected between 2005 and 2009, as well as long-term monitoring data collected in 2010 through As noted above, inundation of portions of the monitoring plots resulted in vegetation changes (e.g., dieback) in 2009 compared to biomonitoring from 2005 to In 1 Reed, P.

14 COLD SPRING 2016 LONG-TERM BIOLOGICAL MONITORING REPORT, DENMARK, MAINE 2016 Biomonitoring Results Comparison with Baseline Data 2016, each wetland plot was dominated by hydrophytes. The species diversity and abundance within each monitoring and reference plot in 2016 was similar to the data collected in 2009 through Overall, the dominant species, including three-seeded sedge (Carex tripserma), cinnamon fern (Osmunda cinnamomea), and tussock sedge (Carex stricta), were similar in abundance in 2016 compared to data collected in 2010 through One notable change was the decrease in abundance of three-seeded sedge in plot MP-2, which has declined in abundance from 30% cover in 2011 to 3% cover in This decline is attributed to the colonization of tussock sedge within the wetland plot and surrounding area. Tussock sedge is an obligate wetland plant 3 and will form dense, extensive colonies in open wetland areas. The dieback of trees within the wetland as a result of beaver inundation has fostered the colonization of tussock sedge throughout the wetland. In 2016, the vegetation diversity and abundance within the reference plots was consistent and very similar to previous monitoring years. Three-seeded sedge has also fluctuated widely in abundance between 7% and 40% and in RP-2 and RP-3 over the course of wetland monitoring since In summary, the dominance of wetland plants within each monitoring plot and the similarity of the vegetation diversity and abundance in 2016 compared to the reference plots, as well as baseline data collected in 2009 and long-term monitoring data collected from 2010 through 2015 indicate that water withdrawal operations have not had an adverse impact on the wetland community. 4.2 HYDROLOGIC MONITORING Piezometer measurements were recorded monthly at each monitoring and reference location during the growing season between April and October. Appendix F includes graphs illustrating the monthly piezometer water levels between 2006 and As seen in the Appendix F graphs, water levels in MP-1 and MP-3 were generally lower compared with previous monitoring years. Water levels were similarly lower in all the reference plots compared with previous monitoring years. Water levels in MP-2 were within the range of past monitoring including baseline conditions. A comparison of the precipitation data from 2016 indicates that only 6.56 inches of precipitation occurred during the low-flow summer months (i.e., July through September), which is notably lower than previous monitoring years (Table 1). As expected, water levels within the monitoring and reference plots reflected the reduced seasonal precipitation amounts. Water levels within the monitoring plots continue to fluctuate naturally in response to precipitation and evapotranspiration rates. Data collected to-date indicates that water withdrawal operations have not adversely affected wetland hydrology. The continued dominance of hydrophytic vegetation within the monitoring plots similarly support conclusions that wetland hydrology has not been adversely affected by water withdrawal operations. 3 By definition (Reed 1988), obligate wetland plants occur almost always (estimated probability >99%) under natural conditions in wetlands. 3

15 COLD SPRING 2016 LONG-TERM BIOLOGICAL MONITORING REPORT, DENMARK, MAINE Conclusions Table 1. Monthly Precipitation (inches) During Low-Flow Months (July September) Jul Aug Sep Total Appendix G contains a graph comparing the monthly precipitation amounts from the East Hiram National Oceanic and Atmospheric Administration Station # between 2005 and June In July 2009, the East Hiram station discontinued data collection. Therefore, precipitation data collected from the Fryeburg Eastern Slopes Airport weather station (KIZG) were used until March 2010 when a rain gauge was installed at Cold Spring 4. As expected, monthly precipitation data has varied since CONCLUSIONS The biomonitoring conducted in 2016 represents the seventh year of long-term wetland biomonitoring at Cold Spring. The data collected in 2016 continue to indicate that water withdrawal operations have not had an adverse effect on the wetland vegetation or hydrology. The hydrological data and plant species diversity and abundance data collected in 2016 remain comparable to baseline data collected in 2009, as well as long-term monitoring data from 2010 through 2015 and reference plot data. 4 In October 2014, the on-site rain gauge malfunctioned; therefore, precipitation data was obtained from KIZG for October
