Normally, the grain size distribution determines classification of the soil. The soil is defined according to major and minor constituents with the minor elements serving as modifiers of the major elements. For cohesive soils, the clay becomes the principal noun with the other major soil constituents used as modifier; i.e.· silty clay, when the clay particles are such that the clay dominates soil properties. Minor soil constituents may be added to the classification breakdown in accordance with the particle size proportion listed below; i.e. sandy silt w /some gravel, trace clay. no call~ 0-3% trace - 3 -12% some -13 -30% SOIL CONSISTENCY -CRIT.ERIA: Soil consistency as defined below and determined by normal field and laboratory methods applies only to non-frozen material. For these materials, the influence of such factors as soil structure, i.e. fissure systems, shrinkage cracks, slickensides, etc., must be taken into consideration jn making any correlation with the consistency values listed below. In permafrost zones, the consistency and strength of frozen soils may vary significantly and unexplainably with ice content, thermal regime and soil type.

In pervious unfrozen soils, the indicated elevations are considered to represent actual ground water conditions. In impervious and frozen soils, accu~ate determinations of ground water elevations cannot be obtained within a limited period of observation and other evidence on gr.ound water elevations and conditions are required.

Stratagraphic Column · The stratagraphic column or graph delineates the various lithologic rock types or units.: Variations · in percentages of the different lithologies is graphically presented directly to the left of the column. 2. Drilling Rate The drilling rates are calculated per coring run and are shown in feet per hour. The rate of drilling may be correlated to the resistive nature of the rock but other possible influences must be considered, i.e. weather conditions, partial circulation loss, fractures, potential blockages within the core barrel, bit condition, pull down pressure, and operator experience. 3. Rock Quality Designation (RQD) The Rock Quality Designation method of determing rock quality is as fol- lows: Count only those pieces of core which are four inches (10 em) in length or longer and which are hard and sound, sum up the total length of core recovered in each run. The sum is then represented as a percentage over the entire length of the run. If the core is broken by handling or by the drilling process, the fresh broken pieces are fitted together and counted as one piece provided that they form the requisite length of four inches (10 em).

B-2 .r:;;. - I I I I I M14/47 3 5. Joint and Fracture Spacing The following classification explains the codes used in the Joint and Fracture Spacing graph: 6. F-1 Vv'ide: fracture spacing greater than three feet. F-2 Moderately close: fracture spacing eight inches to three feet. F-3 Close: fracture spacing four inches to eight inches. F-4 Very close: fracture spacing two inches to four inches. F-5 Extremely close: fracture spacing less than two inches. Strength The following strength classification 1s used: very hard (VH) - hard (H) - moderately hard (MH) - Cannot be scratched with knife or sharp pick. Breaking of hand specimens requires several hard blows of geologist's pick. Can be scratched with only with difficulty. knife or pick Hard blow · of hammer required to detach hand speci- men. Can be scratched with knife or pick. Gouges or grooves to :!-inch deep can be excavated by hard blow of point of a geologist's pick. Hand specimens can be detached by moderate blow. B-3 ; i I, , f ·c .. , .--. M14/47 4 medium (M) - soft (S) - very soft (VS) - Can be grooved or gouged to 1/16 inch deep by firm pressure on knife or pick point. Can be excavated in small chips to pieces about 1 inch maximum size by hard blows of the point of a geologist's pick. Can be gouged or grooved readily with knife or pick point. Can be excavated in chips to pieces several inches in size by moderate blows of a pick point. Small thin pieces can be broken with finger pressure. Can be carved with knife. Can be excavated readily with point of pick. Pieces 1 inch or more in thickness can be broken with finger pressure. Can be scratched readily by fingernail. (American Society of Civil Engineers) 7. Core Recovery During the drilling process, the bit cuttings are removed by fluid circu- lation. The sample which passes up into the core barrel inay be classified into five categories: (a) Solid core greater than 4" in length; (b) Solid core less than 4" in length; ·· (c) Fragmental material not recovered as core; B-4 ' l r .' \ ·' ' I. M14/47 5 (d) Additional material which may have been lost from the previous core run. This may be the core stump left when the barrel was pulled or material .dropped from the core barrel during its withdrawal from the hole or cuttings which have settled when circulation of drilling fluid was stopped. In addition, core may have been lost by: (e) Erosion of soft or friable material, resulting in a reduction in diameter or length of the core or both. This eroded material may be entirely removed by the drilling fluid. The material which is placed iri the core box consists of items (aL (b), (c) . and (d) above and (omitting (e) from the subsequent discussion) is strictly defined as the total core recovery. If no material falls into class (e), then the total core recovery is 100 percent in that there is not loss of sample. The material which is recovered as solid core pieces at full diameter (a) and (b) above is strictly defined as the solid core 'recovery. It must be stresses that the total and. solid core recoveries are only equivalent when no fragmental material is recovered. This arises .either when the rock is solid or loss of sample is presented wholly by material carried away by the drilling fluid. It should be noted that core recovery is expressed as a percentage of the total run length.

The water will probably be utilized for drinking and sanitary needs. It is currently envisioned that in order to meet peak flow demands for these water uses, a storage reservoir will be necessary for the water system. It is understood that a well capable of production of 100 gpm is desired for the construction camp source. The purpose of the pumping test was to attempt to define a suitable shallow aquifer in the vicinity of the lower camp. Upon determination as potentially suitable, the aquifer characteristics were then to be defined by a pumping test. This data could be useful in subsequent determination of the appropriate production well size to meet the anticipated water demands. Further, data from chemical tests including salt water intrusion and biological information were desired to verify water quality. E1. 2 Proposed Well and Test Location The location of the future well and the present test well was. selected by R&M. In addition to a conceptual understanding of areal geology, considerations of proximity to the proposed lower construction camp, the proposed sewage lagoon, and the proposed water system, entered into the test well location selection. It was also specified by the design engineer that a minimum separation distance of 300 feet be maintained between the well site and Battle Creek. E-1 ~-I 10 4 The Location Diagram Drawing E-01 shows the selected well site location relative to the lower construction camp and other project facilities. The Test Well Site Plan Drawing E-02 presents the layout of the test and observation wells utilized for the drawdown testing program. E2.0 TEST SETUP AND EXECUTION E2. 1 Test Well Installation The test and observation wells were drilled at essentially the same ground surface elevation, i.e. approximately elevation 30 feet (Project Datum). The pumping well was located and drilled 350 feet from Battle Creek. Observation wells were located on two radii from the pumping well; one radius toward the creek, the second radius rotated 120° clockwise from the first. Two observation wells were drilled on each radius, one at 15 feet from the pumping well (i.e. RM 252 and RM 253) and one at 45 feet (i.e. RM 251 and 254). Test holes RM 91 and RM 96 were also treated as observation wells during the pumping test. These holes are located at radial distances of 170 feet and 300 feet, respectively. E2.2 Pumping Well Details As outlined in Subsection 5.4.2 of Volume 1, the pumping well was installed by initially pre-drilling with an 8-inch hollow stem auger to displace any oversized materials. Samples were taken during this effort to provide visual classification of the potential groundwater aquifer. Subsequently, the 4-inch I. D. flush coupled HW casing was installed by. driving in 5 foot lengths in conjunction with jetting and tricone drilling, as required. A 4-inch casing size limitation was due to drilling equipment limitations. The casing was advanced to a total depth of 50 feet and was . cleaned out by jetting to the bottom. In the interest of time savings, the well screen was selected in advance of sampling of the test well soils. Due to the appearance of relative E-2 10 5 uniform subsurface conditions in the Battle Creek Camp soils, an "average" gradation was considered. Based on this average gradation, a Johnson screen of 0.040 inch slot opening was selected, pre-ordered and shipped to the site. The screen, a 10-foot-long 4-inch diameter. mild steel telescoping model with a Figure K packer, was placed to the bottom depth of the casing. The HW casing was then pulled up approximately 9t feet to expose the screen to the aquifer. The Figure K packer, a flexible neoprene ring at the upper end of the screen, forms a sand tight seal against the inside of the casing. A high flow rate, 4-inch, 3 hp, 8 stage 230 volt, single phase submersible Pioneer B70 pump was selected for use in the pump test. The pump came equipped with the electric motor below the intake screen. The outside dimension of the pump is 3-3/4-inches, leaving an anular space around the pump of 1/8-inch. Head loss due to this constriction was considered and found to be negligible. Pump performance data is presented in Drawing E-04. A schematic view of the pumping well and equipment is presented in Drawing E-03. Due to dimensional constraints on the well casing, screen, and pump, the pump intake was placed at a depth of about 36 feet below ground surface, and a net hydrostatic head of 21 feet at the intake ·level of the pump was established. A 2-inch polypipe was installed from the pump to immediately beneath the well seal. At the well seal, the polypipe was necked down to H-inch galvanized pipe. A H-inch ball valve was utilized to maintain a minimum head on the pump. Line pressures were gaged by a 0-100 psi Wika pressure gage. Flow was measured by a H-inch Trident totalizing flow meter. A 10 foot galvanized pipe was attached at the outfall of the meter to conduct water away from the vicinity of the well and observation wells. Power to the pump was supplied by a Lincoln 5 kw generator. Electrical controls between the pump and generator consisted of a circuit breaker for protection of the pump motor from excessive current surges. E-3 f I 10 6 E2.3 Drawdown Test Procedures Initial depth to water table readings were obtained after each borehole was drilled and in the standpipe piezometer immediately prior to turning on the pump. Observation well readings were obtained periodically throughout the pump test utilizing a Soiltest water level sensor. The pumping rate was maximized by reducing the pressure head on the pump to a minimum while .still maintaining pump suction in the well. Repeated attempts to surge well flows to maximize production met with limited success and increased flow from 16 gpm to an apparent maximum of 22 gpm. Pumping continued for a total of 22 hours 49 minutes at 22 gpm, except for a period of about 1 hour when the power was interrupted. Water quality samples were obtained after pumping for approximately 1100 minutes. The sampling effort required some system dismantling and momentary shutdown of the flow. The consequence of the shutdown was a short term turbidity increase which unfortunately was reflected in the sample obtained for quality tests. ·This anomaly went unnoticed due to relative darkness at the time of sampling. At completion of the pumping test, recharge measurements were made for a short period of time. E3. 0 RESULTS OF DRAWDOWN TEST E3. 1 Subsurface Conditions All borings drilled in the vicinity of thE:! water well site encountered sandy gravel with trace amounts of silt. At the pumping well a 4 foot lens of silty sand was encountered at a depth of 23 feet. This lens appears to grade to sand within a 15 foot distance on the two observation well radii. E-4 10 7 Based on penetration resistance blow counts, the sandy gravel material is of medium dense to dense consistency. Seismic profiling done in the vicinity of the lower construction camp was used to estimate the depth to bedrock as between 80 and 120 feet. No boreholes in the lower camp area were drilled beyond a depth of 50 feet during this or any other program, hence the character of the deposits below 50 feet and above bedrock elevations are unknown. It has been assumed herein for purposes of pump test analysis that an unconsolidated aquifer extends to a total depth of 80 feet at the test well site. Laboratory testing of combined samples from a depth of 30 to 40 feet in boreholes RM 94 through RM 97 and from 35 to 50 feet in boreholes RM 250 and RM 251 are reported in Appendix G. Permeabilities thus obtained ranged from 8.6 x 10-3 em/sec (24.5 feet/day) for the RM 94 through -4 . RM 97 series to 4.0 x 10 em/sec (1. 1 feet/day) for the RM 250 and RM 251 combination sample. E3.2 Drawdown Observations Data collected during the drawdown test pumping and recharge periods are presented in Table E-1. A cross-section demonstrating observations of groundwater elevation and subsurface stratiography is presented in Drawing E-05. These data are discussed in detail in the following paragraphs. E3.2.1 Pumping Rate and Pressure The maximum water pumping rate which could be developed with the well-p.ump configuration during the test period was 22 gpm. This rate was sustained for the entire test and represents the flow at which the pump capability exceeds the capability of the well to recharge. A maximum gage pressure of 19 psi (44 feet H20) was held on the line in order to prevent cavitation of the pump. E-5 ' 10 8 Frictional losses in the pipe fittings, and flow meter account for approximately 58 feet of head. Further, a net lift of 16 feet brings the total maximum pressure head against which the pump was acting to 118 feet. According to the composite capacity curves presented in Drawing E-04, the pump. should be capable of a production of 77 gpm. It could be concluded then, that pump limitations did not control the well output. E3.2.2 Drawdown vs. Time and Distance from the Pumping Well Drawdown vs. log of time ·and log of distance plots are presented herein as Drawings E-06 and E-07, respectively. Perusal of the drawdown records and plots yields the observations that: l. Drawdowns measured in all observation wells were very small, i.e. less than 0.5 feet. 2. Drawdown measurements vs. time results in an irregular plot, i.e. not a smooth curve. 3. Drawdown vs. log distance from the pumping well results in an irregular plot, which theoretically should be linear. Drawdown corrections for ·variation of atmospheric pressure were factored into the data reduction. The nearest weather station to the site with readily available records is at Homer Airport. Hourly barometric pressure readings were obtained for the pump test monitoring period and were assumed to be equivalent for the test site. Barometric pressure was found to have varied during the test period within the bounds of 30.25 and 30.31 inches of mercury (0.07 feet of water range). Adjustments of actual drawdown measured for atmospheric pressure variation did not result in smoothing the drawdown data, consequently, drawdowns thus corrected are not reported. E-6 10 9 Considering the irregularities and small drawdown magnitude one must utilize the drawdown vs. time data cautiously. The small magnitude of drawdown can be explained only by the relatively low flow of water from the aquifer. Aquifer recharge which must also be occurring could result in small magnitude drawdowns and/or stable non-changing drawdown readings. Recharge measurements were taken in observation well RM 252 for a period of 40 minutes following stopping of the pumping operation. Recharge is plotted in Drawing E-06. It was observed that recharge occurs relatively rapidly in both the well casing and in observation well RM 252. E3.3 Computed Aquifer Characteristics -Well pumping tests are useful tools for determination of the ability of an aquifer to supply wells· of varying size and depth. Transmissibility and storage coefficients as well as specific capacity and permeability values may be computed from drawdown vs. time and distance plots. Similarily, such values may be computed using recharge curves from the same test. Drawdown and recharge values should be the same from both methods of calculation. The computed coefficients may then be useful in prediction of aquifer drawdown at various times and distances from the pumped production well or well field. Assumptions . in the various formulae for aquifer coefficients are steady state flow conditions; full penetration of the aquifer's thickness by the well and a non-recharging aquifer. Non-equilibrium formulae do exist for fully penetrating, non-recharging well-aquifer relationships. Due to strict non-conformance with all assumptions contained in the well formula derivations as well as the data irregularities, it would appear that analysis of aquifer coefficients should be limited to the more elementary concepts of permeability and transmissibility. E-7 I I I I 10 10 In order to compute the effective permeability and transmissibility for the non-standard well-aquifer configuration, a two-dimensional flow-net approach offers a reasonable basis for consideration (Cedergren, 1977). Assumptions are required for this ·analysis. They are: 1. Aquifer thickness -based on seismic survey data obtained in this investigation in the vicinity of the water well, it is estimated that the total thickness of the aquifer is about 80 feet. 2. Flow to the well is radially uniform. Drawdown measurements on the radii with observation wells were similar hence, this assumption seems reasonable. 3. Flow from the well was at maximum production and was controlled only by the permeability of the aquifer. This assumption was not verified in the pumping test. All efforts were made, however, to ascertain that the well was fully developed prior to commencement of the pump test, which would diminish the likelihood of violation of the assumption. 4. The drawdown pattern observed and represented in Drawing E-05 is a ' steady-state condition. Based on observations plotted against log of time, conformity to this condition is questionable. It may be noted, however, that the final two readings of drawdown recorded in all four observation wells were within 0.01 foot of one another, although separated by 2 hours pumping time. Drawing E-08 presents a two-dimensional flow net analysis for the well pumping test. Note that the aquifer thickness was assumed to be a total of 65 feet (saturated) overlying bedrock. Further, the radius of influence of the pumping well was assumed to be 65 feet. E-8 I , 10 11 E3.4 Comparison of Field and Laboratory Test Data Disregarding violations in assumptions of the various computational procedures, values for permeability and transmissibility are tabulated in Table E-2 for comparison among the three methods discussed herein. It may be observed in Table E-2 that the two field derived values differ substantially, varying by a factor of 16 whereas the laboratory value for samples from RM 94 through RM 97 compare well with the time vs. drawdown method and the laboratory value from RM 250 through RM 252 compares well with the 2-D flow net analysis. E3. 5 Water Quality Tests Water quality tests (results presented in Table E-3 and compared with State of Alaska D.E.C. standards in Table E-4) performed on samples pumped from the well showed satisfactory coliform and inorganic chemicals tests with the exception of turbidity and color. As discussed in Section E2.3, it is believed that this turbidity value is non-representative of the actual well production during steady state pumping. Rather, due to temporary shutdown of the pumping effort, the turbidity and color were temporarily effected. Treatment for removal of excess iron and manganese and reduction of the corrosive nature of the groundwater (Langlier Index) may be required. E4.0 CONCLUSIONS The well pumping test demonstrated that a substantial quantity of water of relatively good quality may be produced from the groundwater aquifer near the lower construction camp. -Based on the aquifer transmissibility values computed it is felt that to produce the desired 100 gpm production rate the lower camp site, a well or multiple wells of a minimum 10-inch diameter should be drilled to the depth· of bedrock, estimated to be about 80 feet. E-9 10 12 Because of the probability of continuous aquifer recharge from Battle Creek, accurate estimates of the radius of influence of the well cannot be made. Continuing the assumption of previous computations, i.e., radius of influence equal to the saturated thickness of the aquifer, the capacity of a well in a watertable aquifer may be made by the equation: where: Q =.1rk (H 2 -h 2 ) 2.3 log 10 (R/r) Q = flow rate, cubic feet per day k = permeability coefficient, feet per day H = original height of watertable above bedrock, feet h = height of watertable above pump at maximum d rawdown, feet R = radius of influence, feet r = well radius, feet For the range of permeability values derived from our pumping well test, a single 12-inch well of 80 feet depth in the presumeably uniform aquifer should produce between 6,130 and 98,600 cfd (i.e. 32 to 510 gpm). It is believed that a well properly constructed in this aquifer should produce water at a rate sufficient to meet the projected construction camp requirements. Further, the effect of drawdown on the level of Battle Creek is likely to be minimal.
