Location and Background Information This report presents the results of a hydrogeologic assessment of the Colorado Landfill Inc. (CLI) , Eaton Landfill facility. The investigation was completed in accordance with the May 1, 1984 Professional Services Agreement between Warzyn Engineering Inc. (WEI) and CLI. The Eaton facility covers approximately 25 acres and is located about three miles northeast of Eaton in the SE 1/4 of Section 21, T7N, R65W, Weld County, Colorado. The Eaton Landfill handles non-hazardous municipal refuse from the Town of Eaton and the surrounding area. The site is bounded on the north, west and east by irrigated farmland and on the south by a county road. The northern two-thirds of the site has been brought to final grades, covered and is under cultivation. The south one-third of the site currently is being filled. FIELD INVESTIGATION A. Scope of Work The hydrogeologic field investigation at the Eaton Landfill consisted of the following activities: 1. Drilling and soil sampling at three monitoring well sites ; 2. Installation of 3 two-inch diameter, threaded PVC monitoring wells with sand pack, concrete surface seal and locking protective steel casing; WARZYN .wowatUr o INC 3. Performance of three short-term baildown permeability tests; 4. Establishment of three surface water monitoring points; 5. Groundwater and surface water sample collection and analysis; 6. Surveying of monitoring well and surface water monitoring point elevations; and 7. Water level monitoring at monitoring wells and surface water monitoring point. 1. Drilling and Soil Sampling The drilling and sampling of the three boreholes for the monitoring wells occurred on May 15, 1984. Logs of the boreholes are included in Appendix B of this report. The three boreholes were advanced using a truck-mounted CME 55 drill rig with hollow stem augers and a center plug bit. Drilling fluids were not used. The drill rig and drilling crew were provided by Drilling Engineers Inc. with technical supervision provided by Warzyn Engineering Inc. Borehole depths ranged from 15 to 25 feet. Split spoon samples were obtained at 2 1/2-foot intervals in the upper 10 feet of each borehole and at 5-foot intervals thereafter. The split spoon sampler was driven using a 140-pound hammer falling freely through a vertical drop of 30-inches in accordance with ASTM specifications. Blow counts were recorded for each 6-inch increment or until refusal (50 blows). Recovered samples were first classified as to texture by the drillers. The driller's classification was then reviewed in the laboratory by a soils engineer who examined each sample. Some general remarks on the subsurface investigation are presented in Appendix A. -2- WARZYN 2. Monitoring Well Installation The three monitoring wells, EMW-1, EMW-2 and EMW-3 (EMW-Eaton Monitoring Well ), were constructed of 2-inch diameter, flush joint, threaded PVC pipe and screen. Threaded end plugs were utilized at the bottom of each well screen. Each well string was threaded together and then installed into the borehole through the hollow stem augers to the desired depth. A temporary cap was placed on the top of each well to exclude foreign debris from entering the well as the augers were withdrawn from the borehole. The annular space around the well was backfilled with coarse sand from the bottom of the hole to a level at least 1 foot above the top of the screened interval . The annular space was then backfilled to approximately 2 feet below the ground surface with a mixture of spoil , powdered bentonite and coarse sand. Protective steel casings with locking caps were then placed around the above-ground PVC pipes and cemented in place. Construction specifications for each of the monitoring wells are included in Appendix C. 3. Permeability Tests Baildown permeability tests were conducted by WEI at each of the three Eaton Landfill monitoring wells on May 16, 1984. The test methodology consisted of drawing down the water level in each well by bailing, then recording the gradual recovery of the water level to approximately 98% of the original static water level . WARZVN IIMOINWINO INC -3- �I The test results were analyzed by a WEI computer program and checked by WEI personnel . The permeabilities calculated from the test results are presented in Appendix D and discussed in the RESULTS OF FIELD INVESTIGATION section of this report. 4. Surface Water Monitoring Points Two surface water sampling points (ESW-2 and ESW-3) (ESW-Eaton Surface Water) and one surface water level monitoring point (ESW-1) were established on Lone Tree Creek, east of the Eaton Landfill site. Sampling Point ESW-2 is located downstream from the landfill area v/nere Lone Tree Creek turns east along the county road, south of the landfill property line. Sampling Point ESW-3 is located upstream of the landfill . Monitoring Point ESW-1 was established at the top of the orange I-beam on the southwest end of the bridge over Lone Tree Creek east of the landfill . The level of the creek was measured relative to point ESW-1. Monitoring point locations are shown on Drawing C 400005-2. 5. Water Sample Collection and Analysis Water samples were collected from each of the three monitoring wells on May 17, and June 19, 1984. The initial round of samples was collected by WEI personnel . The second round of samples was collected by CLI personnel . Samples were collected at surface water sampling points ESW-2 and ESW-3 by WEI on May 17 , 1984 only. Each of the samples was analyzed by Warzyn Analytical Laboratories in Madison, Wisconsin for the following constituents: alkalinity, COD, total hardness, nitrate-nitrogen, TOC, sulfate, ammonia nitrogen, calcium, magnesium, sodium WARZVN Malta Eww0 INC -4- and potassium. Conductivity and pH were measured in the field immediately after sampling. The results of the analyses are presented and discussed in the RESULTS OF FIELD INVESTIGATION section of this report. 6. Surveying A level survey was conducted at the Eaton Landfill on June 15, 1984 by McRae and Short, Inc. of Greeley, Colorado. The three monitoring wells were surveyed to the top of the PVC casing. Monitoring Point ESW-1 was surveyed at the top of the orange I-beam on the west side of the bridge over Lone Tree Creek, approximately 1,600 feet east of the southeast corner of the landfill . The survey results are presented in Table 1 of the RESULTS OF FIELD INVESTIGATION section of this report. 7. Water Level Monitoring Water levels were measured at the monitoring wells and surface water monitoring point during each sample collection round. The monitoring dates were May 17 and June 20, 1984 for each of the wells and May 17, 1984 for ESW-1. Water level data are presented in Table 1 and discussed in the RESULTS OF FIELD INVES- TIGATION section of this report. The measured water levels provided sufficient data to produce a contour map of the potentiometric surface or water table of the shallow aquifer. The map is discussed in the RESULTS OF FIELD INVESTIGATION section and is included on Drawing C 400005-2. WARZVN snow.___iwc -5- REGIONAL SETTING A. Regional Geology The Eaton Landfill is situated on the west flank of the structurally defined Denver basin. The geologic unit found within 25 feet of the surface at the Eaton Landfill is Quaternary-age eolium or windblown deposits. The eolium generally consists of windblown gravel , sand, silt and clay. B. Regional Topography The topography of the Colorado Piedmont is characterized by relatively flat uplands and broad valleys. The Eaton site is located in the flat floodplain of Lone Tree Creek. Ground surface elevations around the site range from Elevation 4,820 in the southeast corner of Section 21 to Elevation 4,840 northwest of the site. Surface water drainage is to the south-southeast via Lone Tree Creek. C. Regional Hydrogeology Hydrogeologic information for the area around the Eaton Landfill has not been documented. This assessment will provide the initial documentation of shallow groundwater flow directions , water quality and permeability data for the water- bearing Quaternary-age deposits in the Eaton Landfill area. RESULTS OF FIELD INVESTIGATION A. Geology The subsurface geology at the Eaton Landfill site consists primarily of Quater- nary-age wind and stream deposits of gravel , sand, silt and clay. Bedrock units were not encountered during the drilling program. Monitoring Well EMW-1 in the northwest corner of the site encountered 25 feet of sand with silt and gravel . Wells EMW-2 and EMW-3 were drilled to 15 feet and encountered sandy silt, sand, and gravel deposits. WARZVN .NOW... a -6- �I The Quaternary deposits consist of loose, brown, fine sandy silt to dense, pink coarse sand with little fine to coarse gravel . The soil classifications for the Quaternary deposits range from ML to SM to SP using the Unified Soil Classification System (USCS) . Refer to Appendix B for summary of USCS. B. Hydrogeology Based on the first two rounds of water level monitoring by WEI and CLI, the depth to groundwater at the Eaton Landfill ranges from 8 to 10 feet at Wells EMW-2 and EMW-3 respectively, to nearly 20 feet at Well EMW-1 in the northwest corner. Groundwater flow beneath the Eaton Landfill is to the southeast based on ground- water elevations measured on June 20, 1984 (Table 1) . The average horizontal hydraulic gradient across the site is approximately 0.005 ft./ft. between upgradient Well EMW-1 and downgradient Well EMW-3. The hydraulic gradient generally corresponds to the topographic gradient across the site. Water levels in Lone Tree Creek are significantly higher than levels in the monitoring wells directly west of the stream. This indicates that one of the following conditions may exist at the site: 1. Lone Tree Creek is recharging the Quaternary deposits adjacent to the stream; or 2. The stream channel is sufficiently impermeable to isolate the stream from shallow groundwater flow. At this time, the existing data are insufficient to determine which of the above conditions exists at the Eaton Landfill .

[las-17-9] WARZYN UNO ISS INC• C -8- Permeability of the Quaternary deposits was calculated from baildown tests at wells EMW-1, EMW-2 and EMW-3. Calculated permeabilities ranged from 5 x 10-4 centimeters per second (cm/s) at EMW-3 to 1 x 10-2 cm/s at EMW-2. The permeability at Well EMW-1 was 7 x 10-3 cm/s. Test results are presented in Appendix D. C. Groundwater Quality -- Groundwater samples were collected from Wells EMW-1, EMW-2 and EMW-3 on May 17 and June 19, 1984. Based on the southeastward direction of groundwater flow at the Eaton Landfill , background water quality is represented by Well EMW-1. Well EMW-2 is located along the eastern edge of the site and is down gradient from the northeast corner of the site. Well EMW-3 is located along the south property line of the landfill and is downgradient from the site. The results of two rounds of water quality sampling at the Eaton Landfill monitoring wells are presented in Table 2. Well EMW-2, shows slightly elevated conductivity and concentrations of alka- linity, chloride, total hardness and sodium relative to the upgradient Well EMW-1 and the down gradient Well EMW-3. The chloride concentration at Well EMW-2 also increased 79 milligrams per liter (mg/1 ) between the first and second sampling rounds. These data indicate that the landfill may have an effect on Well EMW-2. The part of the landfill upgradient from EMW-2 contains the oldest refuse on the site. The second round of analyses indicated slight increases in nitrate-nitrogen and magnesium as well as an increase in conductivity of 680 to 930 micromhos per WARZYN •NOINS\MNO INC -9 TABLE 2 GROUNDWATER AND SURFACE WATER QUALITY DATA EATON LANDFILL MAY - JUNE, 1984 Samples Collected 5/17/84 Samples Collected 6/19/84 Constituent* EMW-1 EMW-2 EMW-3 ESW-2 ESW-3 EMW-1 EMW-2 EMW-3 pH 7.3 6.9 7.3 8.3 8.3 7.2 7.3 7.4 Conductivity 1890 2220 1940 720 705 2810 3150 2620 at 25° C Alkalinity 337 546 361 195 195 341 475 369 Chemical Oxygen Demand 50 32 < 10 < 10 < 10 54 46 31 Chloride 48 140 70 25 29 50 219 69 Total Hardness 856 1210 913 278 319 858 1030 907 Nitrate Nitrogen 10.2 2.07 13.8 1.33 1.09 14.1 5.76 16.2 Total Organic Carbon 10.0 9.6 6.3 11.7 12.2 9.0 11.6 8.9 Sulfate 696 643 685 163 137 627 527 615 Ammonia Nitrogen < 0.10 0.23 < 0.10 < 0.10 < 0.10 < 0.10 < 0.10 < 0.10 Calcium 230 250 242 71 71 215 248 243 Magnesium 83 102 83 26 26 98 117 101 Sodium 117 153 115 50 48 120 160 110 Potassium 8.46 12.6 13.4 13.0 12.5 6.23 9.15 9.78 Calculated Hardness 916 1044 946 284 284 941 1100 1020 * Concentration in milligrams per liter (mg/1 ) unless noted otherwise.

These fluctuations have no apparent cause and are thus considered to be seasonal in nature. The increase in nitrate-nitrogen may be a result of fertilizing nearby irrigated fields. D. Surface Water Quality Water quality data from surface water sampling points ESW-2 and ESW-3 are presented in Table 2. Only one round (May 17, 1984) of surface water samples was collected from the Lone Tree Creek sites. The water quality at both sites was very similar, indicating no impacts on the stream from the landfill . By comparing the surface water quality of Lone Tree Creek with the groundwater quality of the monitoring wells, it appears that each is quite distinct. Concentrations of the majority of the constituents measured in the groundwater samples greatly exceed those of the surface water samples. The significant difference in water quality between the shallow aquifer and the creek further supports the idea that the two systems are hydraulically separated. SUMMARY 1. The CLI Eaton Landfill site covers an area of approximately 25 acres in the SE 1/4 of Section 21, T7N, R65W, Weld County, Colorado. 2. Subsurface geology at the Eaton Landfill consists of Quaternary-age deposits of gravel , sand, silt and clay that are at least 15- to 25-feet thick. WARZYN •NOINSSI INO INC -11 3. The depth to groundwater ranges from 8 to 20 feet below the ground surface. Groundwater flow is to the southeast at an average horizontal hydraulic gradient of 0.005 ft./ft. The permeability of the Quaternary deposits ranges from 5 x 10-4 cm/s to 1 x 10-2 cm/s. 4. As indicated by water level and water quality data, Lone Tree Creek and the three monitoring wells do not appear to be hydraulically connected. 5. Monitoring Well EMW-2 may be affected by past land filling activities, although only to a minor degree. Leachate has not affected downgradient Well EMW-3. 6. Surface water quality in Lone Tree Creek is consistent between upstream sampling point ESW-3 and downstream sampling point ESW-2. RECOMMENDATIONS Based on the information and conclusions developed during this Hydrogeology Assessment, WEI recommends : 1. Continued monitoring of the three existing monitoring wells on a quarterly basis. 2. Continued water level monitoring at surface water monitoring point ESW-1 on a quarterly basis. [las-17-8] WARZVN SwwNSU INO INC -12- �I APPENDIX "A" Subsurface Investigation GENERAL REMARKS We have endeavored to evaluate subsurface conditions and physical properties of the subsoil as revealed by the borings and laboratory testing. A problem inherent in this evaluation is the variability in engineering properties within soil strata involved, and specifically in any location variation in the soil which is located between borings. Due to natural or man-made causes, subsurface conditions may change with time. Conclusions drawn and recommendations given in this report are for a specific proposed use of this site. They are our opinions and are based upon conditions that existed at the boring locations and such para- meters as proposed site usage, soil loading, elevations, etc. Since subsurface conditions depend on seasonal moisture varia- tions, frost action, construction methods, and the inherent natural varia- tions, careful observations must be made during construction. These should be brought to our attention as it may be necessary to modify the conclusions and recommendations presented herein. -- J APPENDIX B LOGS OF TEST BORINGS • WARZYN [NOINEERINO INC r r LOG OF TEST BORING Symbols WGeneral Notes ` ..

APPENDIX D • BAILDOWN PERMEABILITY TEST RESULTS WARZVN ENGINEERING INC BAILDOWN PERMEABILITY TEST GENERAL PROCEDURES The purpose of a baildown test is to measure the in-situ permeability of subsurface materials. Baildown tests measure the water bearing properties of undisturbed, in-place aquifer material whereas laboratory tests require removal of material from its natural environment. During the collection of samples for laboratory testing, the material is disturbed and a laboratory permeability test may not be representative of actual in-field permeability. The general procedure for a baildown test is to instantaneously remove water from a well by bailing or pumping and measure the rate at which the water in the well returns to its static level . The rate of water level rise and the physical dimensions of the well (screen length and diameter) are directly related to the permeability of the aquifer material . The greater the permeability, the faster the water in the well will return to the static, pre-test level . DATA REDUCTION to The method of interpreting the water level vs. time data that arise from 0.s Na baildown test is that of Hvorslev (1951 )1 , also in NAVFAC (1971 )2. A plot of field 0.2 recovery data shows an exponential decline of recovery rate with time. If the recovery 0.1 • i i I i 0 2 4 6 8 10 is normalized to HTn (Figure b) and ratios 1 of unrecovered head differences are plotted (a) on a logarithmic scale, a straight line plot results (Figure a) . Faster recovery rates WARZYN are expressed as steeper slopes , implying -��•�-� .� Nw►Appr Warzyn Engineering has developed a computer method to efficiently reduce and analyze baildown test field data. Input field data are converted to values which can be used for graphical analysis. A statistical evaluation estimates the fit of data to a theoretical curve. With a screen shape L/R > 8, the expression for permeability K is: z l K = R In (R / liii 2L(t�t,) I I- �1II_ II I STATIC DT t=°° >- HTn H to o 0 W t=0 R—� �— (b) Where: R = Radius of well screen L = Length of well screen HTn = Unrecovered head difference at time tn STATIC = Measured depth to stabilized water level DT = Input data (measured depth to water at time tit) Time, input as hours, minutes and seconds , is converted to seconds of elapsed time. Measured depth to water at time tn (DT) is converted to a ratio of head differences (HT/HO) , or percent drawdown. These values can be plotted on semi-cycle log paper with time on the abscissa.

The correlation coefficient ranges from 0 to -1 . A correlation coefficient of -1 indicates a perfect correlation, or no scatter of points around the best fit curve. Permeability may be evaluated also for various intervals of the recovery data by inputting parametric values of any two selected points. The slope of the line between these points is used to calculate a permeability value. • 1 Hvorslev, M.J. 1951 , Time Lag and Soil Permeability in Groundwater Observations. U.S. Army Corps Engineers.
