The monitoring well system (system) is comprised of four monitoring wells and one piezometer installed by others and one new "leak -detection" device (MW -6) installed as directed at the Site. Generally, groundwater monitoring has been conducted for three of the four Site monitoring wells since as early as June 2011, and for one well: -1 since May 2004. Groundwater from MW -6 was sampled for the second time in November 2017. I A Facility Summary In 1974, Lambland Inc., doing business as Al Organics, began composting manure generated by the lamb feeding operation that existed at the Al Eaton, Colorado location. Over the next 20 years, Al's composting expanded to include operating other facilities and composting other organic materials such as paunch from foul meat packing plants, green waste, waste beer and brewers residuals, food waste, biosolids, water treatment plant residuals with Tier 1 designation, andvarious wood wastes The Eaton Organic Recycling Facility is defined in 6 CCR 1007-2, Part '1 (The Regulations) as a "compost facility" and is operating a Class 3 organic composting facility since 2015. An Engineering, Design and Operations Plan (EDGE') stamped May 6, 2014 was approved by the Director and Weld County. The compost facility is unrestricted and may produce any variety of compost throughout the facility boundary, but typically produces compost using yard waste, wood waste, and selected food - wastes. 1.2 Facility Location The Site is located in the eastern plains of the Front Range approximately one and a half miles west of Highway 85, and the town of Eaton, Colorado (Figures 1 and 2). The vicinity of the Site is predominately agriculture and scattered oil well sites (Figure 2). The Site slopes gently to the south and lies at an approximate elevation of 4,850 feet above mean sea level (Figure 3). Although not necessarily in a depression, properties to the north, east, west, and south are at greater elevation than the Site. Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO February 5, 2018 The Site lies within an historic agricultural area that has regional and proximate sources for agricultural/fertilizer constituents of concern that likely has significantly contributed to the overall degradation of water quality throughout the vicinity. The Site also appears to lie in an area designated as highly vulnerable to agricultural nitrate impacts as mapped by Ceplecha (Ceplecha, 2001). As reported by the Colorado Agricultural Chemicals and Groundwater Protection Program (Ag program), shallow groundwater in the Weld sub -region of the Lower South Platte River Basin is known to have elevated nitrate levels. Median nitrate results for the area are reported by the Ag program as 20 milligrams per liter (mg/L). 1.3 Site Assessment Background A limited site assessment was conducted by Terracon during May 2004. The assessment was limited to assessing the hydraulic conductivity of near surface soils in the production area and installation of monitoring well MW -II to assess groundwater quality. Based on Terracon's assessment, the shallow subsurface soils exhibited hydraulic conductivities of 51 x 10-6 and 2 10.7 centimeters per second (cm/s) and groundwater occurred at a depth of approximately 23 feet below ground surface (bgs) and exhibited elevated nitrate (26.9 mg/L), sulfate (1,985 mg/L), and total dissolved solids (3,428 mg/L) concentrations. Additional subsurface characterization was conducted in summer 2011 by R now known as Souder Miller & Associates (SMA). Shallow subsurface soils exhibited hydraulic conductivities ranging from 4.7 x 10-5 to 5.9 x 10-8 cm/s which are similar to data reported by Terracon. Subsurface soils were described by A as clays, silts, a n d sands with some water -bearing gravel occurring at variable depths. Bedrock was reportedly encountered at boring locations MW -2 (P1-2) and MW -5A at depths of 21 and 23 feet bgs, respectively. SMA installed two monitoring wells (MW -2 and MW -3) in June 2011 and two more monitoring wells (MW -4 and MW -5) in August 2012. A replacement well for MW -5 (MW -5A) was installed in June 2013. Additionally, several test pits were excavated and examined. Based on SMA's characterization, depth to groundwater varies across the Site, but shallow groundwater that suggests mounding1'2 was observed in the vicinity of neighboring unlined ponds and Graham Seep located near the southwest portion of the facility. SMA reports groundwater flowing to the southeast at gradients of approximately 0.011 ft/ft. SMA further reported3 elevated nitrate, sulfate, and specific conductivity concentrations that may be related to off -site proximate sources. "It should be noted that the relatively shallow depth to groundwater in Test Pit l suggests that there may be a groundwater mounding effect in the vicinity of the unlined ponds located along the west side of the property." EDOP, Hydrogeologic Report by KRW dated May 6, 2014, page 9. 2 "Also, it should be noted that localized groundwater recharge provided by the unlined ponds just west of MW -2 creates a mounding effect in the vicinity of the ponds during irrigation season." EDOP, Hydrogeologic Report by KRW dated May 6 2014, page 1 3 "The presence of elevated nitrate and TLS concentrations in the uppermost alluvial water bearing zone may be related to the agricultural operations on and adjacent to the property." EDOP, Hydrogeologic Report by KRW dated May 6, 2014, pg, 14 Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO February 5, 2018 2.0 Geology and Hydrogeology 2.1 Geology The Site lies on the northeastflank of the Denver Basin which extends from Greeley in the north to Colorado Springs in the South and from the Front Range in the west to Limon in the east. The greater Denver Basin is a north -south trending asymmetrical down -warp involving as much as 13,000 feet of Sedimentary rock. The Denver Basin consists of Precambrian crystalline basement rock overlain by a thick section of pre -Cretaceous and Cretaceous sedimentary units. The formations beneath the upper -Cretaceous Pierre Shale are likely thicker than the 3,135 feet observed on the western flank of the basin (Weimer, 1973). The Pierre Shale is approximately 8,000 feet thick and consists of fossiliferous marine shale, silt, and clayey sandstone, containing numerous calcareous concretions (McWhorter and Ortiz, 1978). The Pierre Shale is the lowest geologic unit of interest and considered the base of the water yielding units in the Denver Basin (Robson, 1987). The Fox Hills Sandstone lies above the Pierre Shale and is composed of calcareous marine sandstone interbedded with dark -gray to black sandy shale and some massive white sandstone (McWhorter and Ortiz, 1978). The thickness of the Fox Hills Sandstone likely ranges from 60 to 300 feet (Weimer, 1973). The Laramie Formation overlies the Fox Hills Sandstone and is the uppermost bedrock unit in the vicinity of theSite. The Laramie Formation consists of yellow -brown and gray to blue -gray soft carbonaceous shale and clay -shale interbedded with sand and shaley sand (McWhorter and Ortiz, 1978). The Laramie contains cross -bedded gray to buff sandstone, which is slightly to well -cemented, and contains coal in the lower portion. Overlying the Laramie Formation are recent deposits of alluvium and eolian sand. The alluvial materials consist of silty, clayey, fine to coarse grained sands with occasional gravel. The eolian sand is generally of uniform thickness. The bedrock formations described above dip gently to the southwest toward the center of the basin. The upper limit of the competent bedrock beneath the Site is an erosional surface controlled by, and generally reflecting the northeast dipping surface topography. 2.2 Hydrogeology The Denver Basin comprises a portion of the Colorado Piedmont Section of the Great Plains physiographic province. Surface drainage in the basin is divided into a portion that flows to the South Platte River and a portion that forms part of the Arkansas River watershed. The major streams in the portion within the South Platte catchment include Plum Creek, Bear Creek, Cherry Creek, Clear Creek, Box Elder Creek and Bijou Creek. The South Platte River enters the basin a few miles southwest of Denver and flows in a Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO 3 February 57 2018 general northerly direction to Greeley where it turns eastward toward the High Plains region (McWhorter, 1984). The significant bedrock aquifers of the Denver Basin are, in descending order; the Dawson, Denver, and Arapahoe formations of the Dawson Group; the Laramie -Fox Hills formations; and the Dakota, Lyons, and Fountain formations. The Dawson Arkose is the uppermost of the aquifers in the Upper Cretaceous Dawson Group. It consists of interbedded sandstone, conglomerate, shale, and clay comprising a total thickness of as much as 1 100 ft. According to the Colorado Division of Water Resources (1976), the lower 400-500 ft. consists mainly of coarse, arkosic and micaceous sandstone and is the principal water bearing zone within the Dawson aquifer. Immediately below the Dawson Arkose, the Denver formation consists of a series of sandstones that thin toward the east and become interbedded with clays and shales. The lowest member of the Dawson Group is the Arapahoe formation which ranges in thickness from 500 to 600 ft. The lithology is dominated by sandstone and conglomerate. Some 300 ft. or more of sandstone is locally present and provides a reliable source of water of good quality. The Laramie -Fox Hills aquifer is the next significant aquifer below the Arapahoe. This aquifer includes the Milliken sandstone of the Fox Hills formation and the A and B sandstones of the overlying Laramie. The portion of the Laramie formation extending between the top of the B sandstone and the base of the Arapahoe is thought to be the confining stratum for the Laramie -Fox Hills aquifer. The average thickness of the Laramie -Fox Hills aquifer is 200 ft. but ranges upward to about 400 ft. Individual sandstone strata form the water bearing intervals and are often separated by 5-20 ft. of shale. Locally, 100-250 ft. of net sandstone thickness is available for water production. The Dakota aquifer consists of the upper 100 ft. of the South Platte and Lytle formations of the Dakota Group. Ground waters of usable quality are found in the Dakota only near the west boundary of the basin where the Dakota outcrops. Like the Dakota aquifer, the Fountain formation and the Lyons sandstone are useful aquifers only near the outcrop on the western side of the basin. These aquifers are Permian in age and are separated from the Dakota by Lykins, Ralston Creek, and Morrison formations. Except near the outcrop areas, all of the above aquifers are artesian. Confining beds are clay and shale strata, but are not believed to preclude vertical communication between the Dawson Arkose, the Denver, the Arapahoe, and the Laramie -Fox Hills. The piezometric head is generally greatest in the uppermost aquifer (i.e. the Dawson Arkose) and decreases with depth to the Laramie -Fox Hills, at least in the undisturbed, pre -development state. This downward gradient is thought to result in some small Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO 4 February 5, 2018 downward movement of water from aquifer to aquifer. The hydraulic properties of the aquifers vary substantially, both within individual aquifers and from aquifer -to -aquifer. 3.0 Monitoring Well System Summary There are four monitoring wells and one piezorneter installed by others within the system and one new "leak detection" device excluded from the system. The Director's leak detection device is specifically excluded from the system due to the device being uncertified as required by the Regulations. Generally, groundwater monitoring has been conducted for three of the four Site monitoring wells since June 2011 and for one well: N7 --I since May 2004. The well spacing ranges from approximately 500 feet to 1000 feet. The certified well locations and MW-6MW-6 are shown on Figure 4. Monitoring well MIN -1 Monitoring well MW -1 was installed by Terracon as described in Te rraco n's Limited Site Assessment dated May 27, 2004. Although not explicitly stated or stamped within the report,MW--1 appears to be certified by Dean R. Pearson P.E., of Terracon. MW --I is located on the east side of the facility within 20 feet of the neighboring property and an unlined irrigation ditch. MW --1 is considered down gradient of properties to the northwest, the production area, the septic leach field, and the stormwater pond. The well construction diagram does not show the complete construction details. Based on Al's experience and an inspection of MW --1 , the well is likely constructed of 2 -inch schedule 40 PVC. The diagram shows the well screen length is 15 feet placed from 10 to 25 feet bgs and likely 0.01 slot. The filter pack is placed two feet above the top of the screen with a bentonite and/or cement seal to the surface. Groundwater generally occurs within the screened interval. Sources for constituents of concern are the septic leach field, the stormwater retention pond, the compost production area, and irrigation through canals/water supply wells and application to neighboring crops. Groundwater recharge sources include up gradient (north/northwest) groundwater flow, discharge from the unlined ponds north and west of the well, and likely discharge of applied irrigation at the property east of the facility. Groundwater elevation in this well is strongly influenced by the pumping of water supply wells east of the facility. This well is appropriate for assessing impacts to groundwater from the general vicinity of the site. Had the well been considered representative of Al's operational impact, the results would suggest that since 2004, Al's operations have generally reduced nitrate concentrations and remediated historic agricultural impacts. Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO February 5, 2018 Piezometer PZ-2 Piezometer PZ-2 was originally installed as Monitoring well MW -2 by in June 2011 as described in SMA's Hydrogeological Report dated October 10, 2012 and revised May 2014. PZ-2 appears to be stamped certified by ichael Pretti P, E., of SMA. PZ-2 is located on the west side of the facility within close proximity to the neighboring unlined ponds, unlined seep, and Al's storm water pond. PZ-2 is considered down gradient of the neighboring unlined ponds and seep and associated groundwater mounding. Piezometer PZ-2 is constructed of 2 -inch schedule 40 PVC. The diagram shows the well screen length is 15 feet placed from 5 to 20 feet bgs and 0.01 slot. The filter pack is placed one foot above the top of the screen with a bentonite and/or cement seal to the surface. Groundwater generally occurs within the screened interval. Due to elevated ( > 4 feet) seasonal groundwater mounding in the proximate vicinity, the source for constituents of concern are chiefly the unlined neighboring ponds and recharge from the unlined Graham Seep. Notwithstanding, the Director's4 opinion, piezometer PZ-2 is solely appropriate for assessing impacts to groundwater from the neighboring unlined ponds and flow associated with Graham Seep. Monitoring well MW -3 Monitoring well MW-3MW-3 was installed by MA in June 2011 as described in SMA's Hydrogeological Report dated October 10, 2012 and revised May 2014. Well -3 appears to be stamped certified by Michael Pretti P.E., of SMA. MW -3 is located at the northeast corner of the facility► within 20 feet of the neighboring crops and an unlined irrigation ditch. MW -3 is considered down gradient of property and farming operations to the north and northwest of the compost facility. Well MW -3 is constructed of 2 -inch schedule 40 PVC. The diagram shows the well screen length is 15 feet placed from 19 to 34 feet bgs and 0.01 slot. The filter pack is placed two feet above the top of the screen with a bentonite and/or cement seal to the surface, Groundwater generally occurs within the screened interval. Sources for constituents of concern are the neighboring crops to the north and likely crops to the east as well. Groundwater recharge sources include up gradient (north) groundwater flow►, discharge from the ponds north of MW -3, and likely discharge of applied irrigation at the property east of the facility. Groundwater elevation in this well is strongly influenced by the pumping of water supply wells east of the facility. This well is appropriate for assessing impacts to groundwater from the general vicinity north of the site. "the physical proximity of monitoring well MW -2 to the Facility's leachate field, storm water detention basins, and adjacent ponds makes this a good monitoring well for these impoundments." CDPHE letter dated December 17, 2015 Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO + February 5, 2018 Monitoring e l l MW -4 Monitoring well MW -4 was installed by SMA in August 2012 as described in S MA's Hydrogeological Report dated October 10, 2012 and revised May 2014. Well MW -4 appears to be stamped certified by Michael Pretti RE., of SMA. MW -4 is located on the east side of the facility within 20 feet of the neighboring crops and an unlined irrigation ditch. MW -4 is considered down gradient of the production area, the septic leach field, the stormwater pond, Graham Seep, and the unlined ponds to the west. Well MW -4 is constructed of 2 -inch schedule 40 PVC. The diagram shows the well screen length is 20 feet placed from 10 to 30 feet bgs and 0.01 slot. The filter pack is placed at the top of the screen with a bentonite seal to the surface. Upon initial inspection of the well in August 2016, the completion at the surface did not maintain a seal. Subsequently and at l's demand, SMA reset the surface seal to preclude short circuiting of the welt Groundwater generally occurs within the screened interval. The longer screen interval (20 -feet of screen) at MW -4 likely accounts for the lower nitrate concentrations observed at MW -4 as compared to concentrations observed at MW -I (15 -feet of screen). Generally, in agricultural settings, younger and shallower groundwater bearing zones are more nutrient -impacted than older and deeper groundwater bearing zones. Longer well screen intervals allows for the mixing of upper and lower water bearing zones. Sources for constituents of concern are the unlined ponds, the septic leach field, the stormwater retention pond, the compost production area, Graham Seep, and neighboring crops. Groundwater recharge sources include up gradient (north/northwest) groundwater flow, discharge from the unlined ponds north and west of the well, and likely discharge of applied irrigation at the property east of the facility. Groundwater elevation in this well is strongly influenced by the pumping of water supply wells east of the facility. This well is appropriate for assessing impacts to groundwater from the general vicinity of the Site. Had the well been considered representative of ►l's operational impact, the results would suggest that since 2004, l's operations have generally reduced nitrate concentrations and remediated historic agricultural impacts. Monitoring well MW -5A Monitoring well MW -5A was installed as a replacement well for MW -5 by SMA in June 2013 as described in SMA's Hydrogeological Report dated October 10, 2012 and revised May 2014. Well MW -5 has since been plugged and sealed. Well MW -5A appears to be stamped certified by Michael Pretti P.E., of SMA. MW -5A is located on the north side of the facility within 150 feet of the neighboring property and 225 feet from the north unlined irrigation ditch and unlined pond with associated settling basins. MW -SA is considered down gradient of the unlined irrigation ditch and unlined pond/settling basins. Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO February 5, 2018 Well - A is constructed of 2 -inch schedule 40 PVC, The diagram shows the well screen length is 20 feet placed from 4Y2 to 24% feet bgs and 0,02 slot. The filter pack is placed to the top of the screen with a thin 9 -inch bentonite seal above the screen and then sand packed to the surface. Groundwater generally occurs within the screened interval. Due to groundwater mounding in the proximate vicinity during irrigation season, the source for constituents of concern are chiefly the unlined ditch and unlined ponds and upgradient historic nutrient impacts. However, due the lack of a proper annular seal, the shallow screen interval, and nativesands from the screen interval to the surface, this well has potential to short circuit during flood/storm events. Director's device MW -6 Director's device: MW -6 was installed as a 'leak detection" device for the stormwater pond. The Director, having assumed responsible charge of the device, had ample opportunity to certify the device; however, the device has not been certified as required by Appendix B of the regulations and the approved Groundwater Monitoring Plans within the EDOP. As such, Al considers all analytical data collected from the device objectionable, since no one is willing or capable of verifying the Director's device is appropriate. The device is located south of the stormwater pond and within 525 feet of the neighboring unlined ponds and Graham Seep to the west. The device is considered down gradient of the unlined neighboring pond, the septic leach field, Graham Seep, and the stormwater pond. The device is constructed of 2 -inch schedule 40 PVC. The device screen length is 10 feet placed from 9 to 19 feet bgs and 0.02 slot. The filter pack is placed one foot above the screen with a bentonite seal above the filter pack to the surface. Groundwater generally occurs near the top of the screened interval. Due to groundwater mounding in the proximate vicinity, the multiple sources for nutrient constituents of concern, the inconsistent construction of the pond liner, and other technical reasons6, the device is incapablee of quantifying a volume/rate of seepage from the storm water pond with any degree of certainty. The device is inappropriate for 5 "Modifications to the plan will be made as appropriate and in compliance with CDPHE requirements based on these evaluations. The number, spacing, and depths of groundwater monitoring systems will be certified by a qualified groundwater scientist." EDOP, Appendix H, page 5 6 "The empirical data developed by CVDRMP P illustrate that monitoring wells are an unreliable tool for detecting impacts of lagoon seepage on groundwater even under relatively favorable hydrogeologic conditions. In most cases, seepage remains either not evident or inconclusive based on groundwater testing." Evaluation of Earthen Liquid Dairy Manure Lagoons, t ...; LSCE 2017 7 "More fundamentally, groundwater constituent concentrations do not yield information on the concentration of the lagoon seepage, the seepage rate, overall subsurface mass loading rate, or the duration of the loading. Although groundwater monitoring generates quantitative information, this information can only be used qualitatively with respect to lagoon seepage, i.e., supporting a statement such as, "groundwater chemistry is (or is not) indicative of lagoon seepage". Since guidelines, standards, and laws for the construction of existing earthen lagoons were intended to control seepage but not to stop it, seepage is to be expected and a data collection effort (e.g., groundwater sampling via monitoring wells or other means) that supports a qualitative statement of whether a lagoon seeps or not has limited utility for devising a path to subsurface N -emission reductions on a dairy farm scale." Evaluation of Earthen Liquid Dairy Manure Lagoons,.....; LSCE 2017 Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO February 5, 2018 assessing groundwater conditions with respect to the storm water pond liner performance. Monitoring Well System Summary There are effectively two monitored units at the Site: the compost production area and the storm water retention pond. Neither of which significantly contributes to groundwater recharge beneath the Site as compared to the orders of magnitude greater recharge volumes from proximate off -site seasonal sources comprised of similar constituents of concern. In the absence of a unique identifier (specific constituent linked to a specific on -site source), interpretation of groundwater quality data is most successful with consideration of the well's source area. Monitoring wells positioned down gradient of monitored units are typically intended to intercept groundwater which originates under the monitored unit only. However, it must be recognized that this is not possible when seepage from the storm water pond approaches zero and neighboring unlined pond's/ditch's seepage is significant, such as is the case here. As pond seepage decreases, the source area of a down gradient monitoring welt will extend beyond the footprint of the monitored unit (pond). Further, recharge or groundwater mounding associated with the proximate unlined ponds/ditches and Graham Seep during irrigation season already extends well beyond the storm water retention pond. Under these circumstances, groundwater chemical characteristics cannot be unambiguously attributed to the pond liner performance or site operations notwithstanding the statistical analysis. One of the most basis premises of groundwater monitoring is that the monitoring well must provide a representative hydraulic connection to the monitored unit. Without this representative hydraulic connection, the groundwater analytical data cannot be interpreted in relation to the flow system dynamics or the transport of constituents of concern in the monitored unit. Groundwater monitoring has limitations, particularly in agricultural settings where the flow of monitored constituents of concern are present at significantly greater volumes and mass in upgradient and proximate locations in comparison to Site sources. To put it simply, groundwater impacts from agricultural operations in the vicinity of the Site are more than likely masking impacts that may originate at the composting facility. 4.O Groundwater Data Summary 4.1 Sources for constituents of Concern There are significant historical sources for nutrients (constituents of concern) in the vicinity of the Site. Most notably are the surrounding adjacent parcels and the significant historical duration and mass of fertilizer/manure application to crops. Additionally, irrigation water flowing in the unlined ditches north and east of the Site may collect nutrients from crop application and tail water return. Locally, the septic leach Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, C February 5, 2018 field lies directly between the upgradient Graham Seep and the down gradient storm water retention pond. Cultivation of crops requires applied irrigation and nutrients to penetrate the soil surface and leach through to the root zone. It is likely that surrounding cultivated parcels have historically applied over 150 pounds (Ibs) of nitrogen per acre as fertilizer annually. Technical reports from exhaustive studies conducted in the Central Valley of California suggest a proportional relationship of 1000:18 between subsurface nitrogen -emissions from fertilized and irrigated cropland and from earthen -lined water retention features in similar agricultural land use settings. Estimates of annual applied irrigation and surrounding fertilizer application at neighboring agricultural facilities comprising approximately 150 acres are 100 million gallons of water and 15,000 lbs of nitrogen. Als estimate of annual precipitation over the production area is approximately 325,000 gallons. 4.2 Groundwater Recharge Sources There are several significant sources for groundwater recharge in the vicinity of the Site. Most notably are the surrounding adjacent parcels and the application of irrigation of unknown quality to crops. Locally, there are several unlined surface water retention features in close proximity to the Site.Other notable sources are the unlined irrigation ditch that borders the Site to the east, another unlined irrigation ditch on the north side of County Road 76, and the likely leaking drain that connects the irrigation ditch to the north and Graham Seep. Groundwater recharge features are shown on Figure 5. Based on previous assessments of surface and near surface soils within the production area of the Site, the Site soils are likely to preclude significant infiltration of precipitation that comes in contact with compost and feedstocks. Infiltration within the production area and discharge from the storm water pond are not significant sources of groundwater recharge when compared to the orders of magnitude significant irrigation - related recharge volumes of off -site proximate and upgradient sources for nutrient constituents of concern. 4.3 Ground ater Monitoring Groundwater from the wells and MW-6MW-6 was measured in the field during purging for specific conductance (EC), temperature, pH, oxidation-reduction potential or redox (ORP) and dissolved oxygen. Well and device locations are provided as Figure 4. Measured field water quality parameters are summarized in Table I . Groundwater from Site wells and MW-6MW-6 was collected on November 29, 2017 and submitted to Colorado Analytical Laboratory. The groundwater samples were analyzed for the constituents described in the approved EDOP with the exception of volatile organic compounds and semi -volatile organic compounds which will resume testing in May 2019. $ "This compares well to Addressing Nitrate in California's Drinking Water (Harter, Lund et al. 2012).

LSCE 2017 Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO 10 February 5, 2018 4.4 Groundwater Elevations Depth -to -groundwater and total well depth measurements were gauged in wells: MW -1, FEZ -2, MW -3, MW -it; MW -5A, and the Director's MW -6. Groundwater elevations are calculated by subtracting depth -to -groundwater measurements from surveyed top -of - casing elevation at each location. During the November 2017 groundwater monitoring event, depth -to -groundwater measurements ranged from approximately 5% to 9 feet bgs for wells on the west boundary and from approximately 15 to 18% feet bgs for wells on the east boundary. Table 2 summarizes depth to water measurements and groundwater elevations for Site wells and devices. Groundwater elevations across the site are significantly affected by major storm water events, seasonal irrigation, and the pumping of water supply wells during the growing season. Data from the Site hydrographs show declines in groundwater elevations for wells at the west property boundary of greater than four feet when irrigation is not flowing (September through March). During the same period, wells on the east boundary show rising groundwater elevations (well recovery) when water supply wells are shutdown. During the irrigation season, the opposite holds true. Groundwater elevations at wells along the west property boundary rise due to massive recharge/mounding and elevations at the wells along the east property boundary decline due to water supply well pumping east of the Site. During May 2017, the first major storm event showed an immediate rise of groundwater of about 2 feet for wells (MW -5A and F2-2) at the west property boundary. However, during subsequent large storm events, only PZ-2 showed groundwater elevation rises of greater than one foot (1.41', 1.0 1, and 1. 1'), while MWW- A showed groundwater elevation rises no greater than 0.19 feet from the same storm events. The data suggests significant groundwater mounding beneath the storm water pond during irrigation season from storm events and irrigation flow. Groundwater elevation summaries and hydrographs of groundwater elevations with time are provided in Appendix . 4.5 Groundwater Flow Direction The natural topography suggests that groundwater would chiefly flow from higher ground surface elevations at the northeast corner of the Site towards areas of lower elevation to the southwest. However; Site groundwater data supports groundwater flowing from northwest to southeast of the Site at a gentle gradient of 0.009 ft/ft. The shift from anticipated groundwater flow is attributed to the significant groundwater recharge along the west property boundary and the pumping of water supply wells east of the property boundary that directs Site groundwater eastward during the irrigation season, Figure 6 shows groundwater elevation contours for Site monitoring conducted on November 9, 2017. Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, Co 11 February 5, 2018 4.6 Water Quality The Site lies within an historic area where neighboring agricultural operations within the vicinity have contributed to the overall degradation of water quality. Shallow groundwater in the vicinity of the Site is known to be impaired with regards to nitrates. As reported by the Colorado Agricultural Chemicals and Groundwater Protection Program (Ag program), shallow groundwater in the Weld sub -region of the Lower South Platte River Basin is known to have elevated nitrate levels. Median nitrate as nitrogen results for the area are reported by the Ag program as 20 milligrams per liter (mg/L). Analysis of groundwater from site wells indicates nitrate and sulfate concentrations exceed standards. Tables 3 and 4 summarize the analytical results of groundwater samples collected from the on -site monitoring wells and MW -6. Table 3 summarizes results of pH, salinity, and the major cations and anions. Table 4 summarizes additional inorganic metals analyses. Laboratory reports with Chain -of -Custody documentation are provided in Appendix B. Since 2004, nitrates and other nutrient -constituents have generally decreased. Nitrate concentrations reported for Site wells in November 2017 show less variability than previous monitoring events. Particularly, nitrate concentrations across the Site narrowly range from 10.45 mg/L (MWa3) to 14.53 rng/L (MW -I). 4.7 Statistical Analysis Statistical evaluation of groundwater monitoring results is provided by Al's third party engineer. It should be noted that MA's statistical findings are solely under the responsible charge of A's qualified groundwater scientist. Al's findings for the groundwater monitoring program are separate and under the responsible charge of Al Organics' qualified groundwater professional. Essential excerpts from M.'s statistical evaluation are provided as Appendix C. SMA s complete statistical analysis is provided within the enclosed compact disc. 5.0 Findings Similar to the Central Valley of California, historic and current agricultural operations in the vicinity of the Site are most likely responsible for the nutrient (nitrate, sulfate, and total dissolved solids) concentrations observed in Site monitoring wells. During 2017, groundwater monitoring was conducted within two distinct and separate groundwater flow regimes. During the May 2017 groundwater monitoring event, groundwater was affected by a major storm event where a significant rise in groundwater elevations was exhibited across all wells in the system. Concentrations for constituents of concern were reported for the May 2017 event as significantly elevated in most wells, Groundwater Monitoring Report Eaton Organic Recycling Facility Weld County, CO 12 February 5, 2018 Curing the November 2017 groundwater monitoring event, groundwater elevations suggest that groundwater flow was equilibrating in the absence of seasonal significant recharge and adjacent water supply welt pumping. Under this groundwater flow regime, concentrations for constituents of concern were reported as significantly decreased in most wells as compared to the May 017 groundwater monitoring event. These results further suggest that seasonal upgrad lent agricultural nutrient applications, associated irrigation, and major storm water events are responsible for the elevated nutrient concentrations observed in Site monitoring wells. As a point of clarification regarding Al's May 2017 Groundwater Monitoring Report: all clay -lined water retention ponds leak to a certain degree. In Al's May 2017 Groundwater Report, the statement that "Al finds the storm water pond is definitely leaking" was intended to acknowledge that fact only. There is not currently, nor has there been presented any verifiable evidence demonstrating or supporting that a representative hydraulic connection9 with the uppermost aquifer beneath the facility exists as was inferred by the comment presented in the CDPHE correspondence dated September 20, 2017. 6.0 Limitations Al has prepared this Report based on available information consistent with the standards of care and skill ordinarily► exercised by members of the profession practicing under similar conditions in the geographic vicinity and at the time the monitoring was performed.

Additional information associated with the following statistical evaluations and related discussions are supported by the Unified Guidance (EPA, 2009). Non-VOC constituent concentrations and, when applicable, SanitasT , statistical analysis results for wells MW -1, MW -3, MW -4, MW -5A, and Mw -6 may be found in Appendix C. Background ranges are included in Appendix C. All statistical analyses were performed in accordance to the approved Engineering Design and Operations Plan (Pretti, 2016). Laboratory analyses for VOCs and SVOCs were not conducted during the November 2017 monitoring event for any samples collected at any wells in the monitoring well network. VOCs and SVOCs will be monitored beginning in May 2019. MW -1 (Down -Gradient) No constituent concentrations exceeded the Shewhart-CUSUM Control Chart/Prediction Limit during the November 2017 monitoring event at well MW -1. The Mann -Kendall trend analysis indicated no statistically significant increasing trends during the most recent monitoring event. Arsenic, calcium, chloride, chromium, magnesium, nickel, and nitrate concentrations exhibited statistically significant decreasing trends during the November 2017 monitoring event. The detected concentrations of nitrate and sulfate at MW -1 were 14.53 mg/I and 1411 mg,fl, respectively, during the November 2017 monitoring event, which exceed the Basic Standards for Groundwater (BSGW) of 10 mg/l and 250 mg/I, respectively. No other constituent concentrations exceeded the BSGW at well MW -1. MW -3 (Side -Gradient) No constituent concentrations exceeded the Shewhart-CUSUM Control Chart/Prediction Limit during the November 2017 monitoring event at well Mw -3. The Mann -Kendall trend analysis indicated no statistically significant increasing trends during the most recent monitoring event. Arsenic, beryllium, cadmium/ cobalt, lead, nickel, vanadium concentrations exhibited statistically significant decreasing trends during the November 2017 monitoring event. The detected concentrations of nitrate and sulfate at MW -3 were 10.45 and 1513 mg/I, respectively, during the November 2017 monitoring event, which exceed the BSGW of 10 mg/1 and 250 mg/1, respectively. No other constituent concentrations exceeded the BSGW at well MW -3. MW -4 (Down Gradient) No constituent concentrations exceeded the 5hewhart-CU LM Control Chart/Prediction Limit during the November 2017 monitoring event at well MW -4, with the exception of nitrite. The non -parametric prediction limit for nitrite concentrations at well MW -4 is 0.15 mg/1, and during the November 2017 sampling event, nitrite was detected at a concentration of 0.29 mg/I. November 2017 was the first nitrate concentration prediction limit exceedance at well Mw -4. It should be noted, the CUSUM for calcium, magnesium, sodium, and sulfate exhibited control chart limit a .ceedances, while detected concentrations were less than control chart limits, The Mann -Kendall trend analysis indicated no statistically significant increasing trends during the most recent monitoring event. Arsenic, barium, cadmium, chromium, cobalt, copper, lead, nickel, selenium, vanadium, and zinc concentrations exhibited statistically significant decreasing trends during the November 2017 monitoring event. The detected concentrations of nitrate and sulfate at MW -4 were 11,97 and 1478 mg 'I, respectively, during the November 2017 monitoring event, which exceed the BSGW of 10 mg/I and 250 mg/I. No other constituent concentrations exceeded the BSGW at well W-4. MW -SA (Up -Gradient) No constituent concentrations exceeded the Shewhart-CUSUM US U M Control Chart/Prediction limit during the November 2017 monitoring event at well MW -SA. The Mann -Kendall trend analysis indicated no statistically significant increasing trends during the most recent monitoring event. Beryllium, nickel, selenium, and zinc concentrations exhibited statistically significant decreasing trends during the November 2017 monitoring event. The detected concentrations of nitrate and sulfate at MW -SA were 11,43 and 1471 mg'"i, respectively, during the November 2017 monitoring event, which exceed the SS W of 10 mei and 250 mg, 1. No other constituent concentrations exceeded the BSGW at wellMW-5A. MW -6 (Down -Gradient) Monitoring well MW -6 was sampled for the second time during the November 2017 sampling event. Statistical analysis for constituent concentrations will begin once an adequate number of sampling events have occurred to populate the background set. The detected concentrations of nitrate and sulfate at MW -6 were 11.68 and 1360 mg `I, respectively, during the November 2017 monitoring event, which exceed the BSGW of 10 mill and 250 mg,'1. No other constituent concentrations exceeded the BSGW at well MW -6.
