  • 1.0 INTRODUCTION

    The present program of water well construction and testing has been carried out at the request of the

    Glenmore-Ellison Improvement District (GEID) to develop a 12-inch production well, which will be used

    as a supplementary source of water for the District’s water supply system. As shown in Figure 1, the new

    well is located at the northwest end of the Kelowna Municipal Airport along Old Vernon Road. Verbal

    confirmation to proceed with the well completion program was provided in late September, 2000, by Mr.

    Mike Rojem, Manager of the Glenmore-Ellison Improvement District.

    Background information for the present well construction program, was provided by the results of a

    groundwater investigation (see report dated June 17*, 1999) conducted during April and May of 1999

    under the supervision of Kala Groundwater Consulting Ltd. (Kula). During the investigation, a six-inch

    testwell was completed with well screens set between 244 and 264 feet. Results of testing at this depth

    interval indicated that the water quality exceeded the aesthetic limits for iron and manganese. In August of 1999, the well screens were pulled from the original setting and re-set at I80 to 200 feet. The quality

    from the shallower zone was suitable and a potential yield of at least 750 USgpm was projected. It was

    recommended that a large diameter production well be constructed.

    The present program has involved the drilling of a 12-inch (305 mm) diameter production well,

    completed with 25 feet (7.6 metres) of 12-inch telescopic well screen. Upon completion of the well, a 24-

    hour pumping test was conducted and water samples collected for a chemical and bacteriological analysis.

    The following report outlines the nature of the drilling and testing program and provides a discussion of

    the results. In addition, recommendations are made with respect to a safe pumping rate, pump setting and

    water level monitoring to evaluate long-term performance of the well and aquifer. In the section which

    follows, a brief account of the existing conditions is provided. Detailed information including water

    quality, the driller’s litholog, sieve analysis and pump test data is attached to the Appendices. ,

  • 2.0 BACKGROUND

    2. I Site Description

    The drilling site selected for the present program is located at the nortanwest end o the Kelowna

    Municipal Airport along Old Vernon Road. The property consists of a small parcel of land situated

    between the CNR right-of-way and Highway 97 (see Figure 1 attached). With respect to topographic

    expression, the site is situated along the floor of a tributary valley system, which drains in a southward

    direction from Winfield into Okanagan Lake. The valley contains Wood and Ellison Lakes, plus the

    lower reaches of Kelowna Creek before it drains into Okanagan Lake at Kelowna. The Elevation of the

    study area is approximately 1450 feet (442 metres) AMSL, compared to an elevation of 1140 feet (347

    metres) AMSL for Okanagan Lake near the bridge crossing to Westbank.

    According to a report prepared by H. Nasmith (1962), the surficial deposits occurring along the valley

    bottom (study area) and towards the eastern valley wall, have been designated as alluvial fans, deltas and

    associated stream channels. These deposits are underlain by a thick sequence of fine sand and silt

    material. The latter formation consists primarily of valley fill deposits associated with the Kalamalka-

    Wood Lake Valley, which is a minor valley system running parallel to the main Okanagan valley.

    !

    Moving a little further west, the surficial deposits have been mapped as glacial fluvial, consisting of

    coarse sand and gravel, which is apparent at the gravel pit located on the Pier Mac property. According to

    the report prepared by H. Nasmith, the coarse gravel material is kettled outwash of glacial origin. The

    closed depressions evident throughout the general area are kettle holes formed by the melting out of

    blocks of glacial ice. It is Kala’s opinion that the drill site selected for the present program is located

    within a transitional zone between the two types of deposits previously djscussed in this section.

    1%

    2.2 Existing Water Wells

    Existing wells in the general area range from low capacity domestic wells to high yielding irrigation

    welIs, depending on location, method and depth of completion. Several flowing wells and springs are

    located along the valley bottom east of Highway 97, which discharge into Mill Creek. Logs of existing

    wells demonstrate considerable variation in lithology, extending across the valley bottom and towards the

    eastern slopes.

    Kak9 Groundwater Consulting Ltd. Page 2

  • A high capacity well was drilled under the supervision of Kalu in 1992 for the Glenmore-Ellison

    Irrigation District on property located immediately east of the Quail Ridge Golf Course. Based on the

    drilling results, the subsurface material at this location was grouped into three units as follows:

    Depth Interval (in feet) Litholopic Description

    Geologic Classification

    0 - 59 Coarse sand with cobbly, bouldery, Kettled outwash gravel, brown

    59 - 99 Clay with sand and gravel Alluvium

    99 - 257 Fine to medium sand with gravel and some cobbles

    Glacial fluvial

    A 16-inch production well was completed in the sand material encountered between 195 and 257 feet

    (59.6 and 78.3 metres). The well was constructed with 62 feet of well screen and has a projected long-

    term yield of 2000 USgpm with a specific capacity of 6 1 USgpm/foot of drawdown.

    More recently, KaZa supervised the construction of an %inch production well at the request of CRC

    Construction Ltd. for the Phase I1 Quail Ridge Golf Course expansion. The new well is located approximately 1 km south of the present drill site on the west side of Highway 97. It is completed with

    42 feet (12.8 metres) of well screen to a total depth of 216 feet (65.8 metres). The safe long-term

    projected yield for this well is theoretically in excess of 1000 USgpm. Taking into account well design

    factors however, the well was rated at 650 USgpm. A partial water quality analysis for the well is

    included in this report.

    Other high capacity wells located in the immediate vicinity include the source wells supplying the airport,

    the wells providing irrigation water for the golf course located immediately south of the airport and the

    well located on the east side of the airport along Old Vernon Road, which supplies the Glenmore-Ellison

    Improvement District. Most of these wells have yields rated at upwards of 500 USgpm. Locations for

    some of these wells are shown in Figure 3 attached.

    2.3 Original Six-Inch Testwell At Airport

    During the completion of the 6-inch exploratory testhole, which was drilled by the cable tool method,

    saturated conditions were encountered at approximately 40 feet (1 2.2 metres) below surface. Material

    Page 3 Kak

    Groundwater Consulting Ltd.

  • above this depth consisted mainly of brown sandy clay with minor gravel. The subsurface material

    encountered within the zone of saturation between 40 and 208 feet (12.2 and 63.4 metres) consisted

    predominantly of coarse clean brown sand and gravel, with layers of fine sand containing varying

    amounts of silt. One of the intervals, 175 to 183 feet (53.3 and 55.8 metres) contained streaks of clay.

    There was a color change from brown to grey at 208 feet (63.4 metres) and the granular material was

    predominantly finer grained to the base of the testhole. A plot of the 40 percent grain size retained (well

    screen design size), as per sieve analysis versus depth is shown in Figure 4. It is interesting to note the

    extreme variation in screen size with depth, varying from a #90 slot (90 thousandths of an inch) near the

    top interval to a #20 slot at the bottom.

    As noted in the introductory section of this report, the test well was originally completed with screens set

    between 244 and 264 feet. Results of testing at this depth interval indicated that the water quality

    exceeded the aesthetic limits for iron and manganese. In August of 1999, the well screens were pulled

    from the original setting and re-set at 180 to 200 feet. The quality from the shallower zone was suitable

    and a potential yield of at least 750 USgpm was projected. It was recommended that a large diameter

    production well be constructed.

    In addition to the improvement in water quality, the aquifer at the shallower depth has a slightly higher

    coefficient of transmissivity. This is based on the results of a six hour pumping test which showed a total

    drawdown of 10.37 metres (34.02 feet) at the end of the test, pumping at a constant rate of 285 USgpm.

    This compares to a total drawdown of 12.41 metres (40.71 feet) after the same time interval, pumping at

    an average rate of 290 USgpm during the original pumping test (May 26", 1999).

  • 3.0 DESCRIPTION OF PRESENT PROGRAM

    3.1 Drilling and Well Completion

    Based on competitive price and availability, Dan-Gare Drilling Ltd. of Vernon, B.C. was selected for the

    drilling project. The production well was drilled with an air rotary drilling rig equipped with a casing

    hammer. With this type of drilling equipment, the casing is advanced as drilling proceeds, and the nature

    of the subsurface material is determined by examining drill cuttings lifted to surface with the drilling rig's

    air compressor. Preliminary estimates of well yield are made in a similar manner, by measuring the

    quantity of water lifted to surface with air. Because of the large diameter of the casing, a second auxiliary

    compressor was used to increase the volume of air.

    The drilling was conducted with 12 inch casing and after penetrating the target water-bearing zone (1 85 to

    21 1 feet), a well screen assembly was installed to the bottom. The casing was then pulled back to expose

    the screens and the well was developed by surging and jetting with compressed air.

    3.2 Aquijer Testing

    In order to evaluate the safe yield of the new well, a 24-hour pumping test was conducted starting on

    January 17", 2001. Pump testing services were provided by Aqua Tech Services of Kelowna, B.C.,

    working under the supervision of Kulu.

    During the test, water pumped from the new 12-inch test well was conveyed through solid 4-inch PVC

    pipe and discharged to waste into a drainage ditch, which conducted the flow of water southward from the

    site. The discharge rate was monitored using a conventional circular orifice meter and water levels in the production well and original 6-inch test well were measured with an electric well sounder. Near the end

    of the pumping interval, water samples were obtained and forwarded to Car0 Environmental Services for

    a water quality analysis. Upon cessation of pumping, recovery was measured in the production well for a

    one hour period.

    4.0 PROGRAM FINDINGS

    4.1 Drilling

    Based on the results of the original explora ory test drilling and the present production well drilling

    program, a summary of findings regarding the surficial geology and hydrogeological conditions is

    outlined as follows:

    0 The original exploratory testhole at the Kelowna Airport was drilled to a total depth of 270 feet (82.3

    metres) with the cable tool method and approximately 220 feet (67.1 metres) of water-bearing sand

    material was encountered;

    0 The gain size of the water-bearing material was variable and ranged from a coarse sand with gravel to

    layers of fine sand with some silt. The 40 percent retained on the sieves (well screen design size)

    ranged from a #20 slot to a maximum of #90 slot;

    0 The formation material turns from a brown to grey color at 208 feet. The material above the 183 foot

    depth interval contains dirty sand with clay streaks between 158 and 183 feet. Above the 158-foot

    interval the material is excellent (coarse grained), but it was decided that screening in this interval

    will limit the total available drawdown in the well.

    During the construction of the new 12-inch production well, some water samples were obtained while

    drilling through the 135 to 160 foot zone to establish iron and manganese concentrations for hture

    reference. Results of these tests are discussed in Section 4.4 on water quality.

    1. 4.2 Well Completion

    Following completion of the 12-inch drilling to the base of the upper aquifer (183 to 210 feet), a

    production well was completed with 25 feet (7.6 metres) of 12-inch (305 mm) telescopic well screen set

    from 185 to 21 1 feet (56.4 to 64.3 metres) below surface as shown in Figure 2. In addition a 2- foot riser

    and “Figure K” packer is attached to the top of the well screens, bringing the top of the assembly to 182.7

    feet (55.7 metres) below ground level. The well screens used in the new well are high flow construction,

    designed to provide more open area per foot of screen and consequently higher production. Based on

    Page 6 Kak

    Groundwater Consulting Ltd. .

  • results-of the sieve analyses, the screen slot size selected consists of #20 slot (20 thousandths of an inch openings) set from 185.0 to 200.7 feet and #18 slot set from 200.7 to 21 1.0 feet below surface. Following

    instgllation of the well screen assembly, the well was developed by surging and jetting with compressed

    air until a sandsilt free condition was achieved.

    4.3 Results of Pumping Test

    Results of the pumping and recovery tests have been plotted on semi-log and log-log graphs of drawdown

    versus time (residual drawdown versus time for recovery) and an interpretation of the aquifer parameters

    and sustainable yield made on this basis. Detailed pumping test data and plots are included in Appendix

    B of this report.

    While pumping at a constant rate of 500 USgpm, the total drawdown observed in the new 12-inch

    production well was 24.60 feet (7.50 metres) after 24 hours. This represents only 18 percent of the total

    available drawdown in the well. It was also noted that the drawdown occurred at a steady rate of 0.7 feet

    (0.21 metres) per log cycle.

    The total drawdown interference noted in the 6-inch observation well, located 42.5 feet (12.95 metres) to

    the northeast was 2.46 feet (0.75 metres) at the end of the 24-hour pumping interval. The rate of

    drawdown in the observation well was approximately one-half of that noted in the production well and

    amounted to 0.4 feet per log cycle. Based on the results, a transmissivity determination for the aquifer,

    using the Theis match curve method of analysis, is 3.2 x lo5 USgpdft.

    Following cessation of pumping the 12-inch well recovered to within 98.5 percent of f i l l recovery in 60

    minutes. A determination and discussion of safe sustainable yield for the 12-inch production well is

    included in Section 5.0 of this report.

    4.4 Water Quality

    A copy of the certificate of analysis for water quality is attached to the Appendix C of this report. Based

    on the results, the water quality for all parameters tested meets the “Guidelines for Canadian Drinking

    Water Qualiw” with respect to health related parameters. As in the case of the six-inch test well (shallow

    aquifer) the concentration of manganese at 0.057 mg/L exceeds the aesthetic objective of 0.05 m g L by a very minor amount and the nitrate level is slightly elevated, which we have no explanation for.

  • 5.0 DISCUSSION OF RESULTS

    i 5.1 Sustainable Safe Yield of I2-Inch Production Well

    The long term yield of a production well is dependent upon a number of factors, the most important being

    the hydraulic properties of the aquifer (transmissivity and storativity), availability of recharge to the

    aquifer and the number of, distance between and pump rate of other wells in the same aquifer.

    The long term yield of the new 12-inch production well at the Kelowna Airport over a 20 year period

    assuming no interference from other wells and 70 percent consumption of available drawdown may be

    expressed by the following:

    I

    Qto = 0.70 x Sa(Q)/(Sloo +5AS) Where :

    QZO = 20 year continuous pumping rate

    Sa = total available drawdown (138 feet)

    Q = aquifer test rate (500 USgpm)

    Slm = drawdown in pumped well at t=100 minutes (23.80 feet)

    AS = drawdown over one log cycle (0.7 feet)

    Applying this formula QZO = 1770 USgpm. __ -~

    With a projected yield of this magnitude, Kala anticipates the question, then why was the test conducted

    at only 500 USgpm? The answers to this question are as follows:

    a) Quotations for a large volume test (1000 to 1200 USgpm) were cost prohibitive; and

    b) It is currently planned to install a variable speed submersible pump in this well, meaning that if our yield projections are out by a small amount, alterations to the discharge rate can be easily made.

    c) The well screen as installed is designed to transmit 750 Usgpm at an entrance velocity of 0.1 feet per

    second.

    Because of the excellent water quality, the entrance velocity of 0.1 feet/sec can be exceeded, and

    therefore Kula is recommending that a pump capable of delivery somewhere between 750 and 1100

    USgpm be installed in the new 12-inch production. I f it is decided to go with the higher pumping rates, it

    Groundwater Consulting Ltd. Page 9

  • is recommended that during initial start-up drawdown measurements should be taken in both the

    production and observation well to confirm projected drawdowns and safe well yield.

    5.2 Pumping Level Projections

    In order to aid in pump design and selection, gala provides a series of pumping level projections in Table

    2 which follows. These projections are all based on continuous pumping for a seven day period.

    At the time of preparing this report the top of casing was 2.0 feet above ground level at the site of the new

    12-inch production well.

    It is currently recommended that a pump setting for the new well be 175 to 180 feet below the top of

    casing. All depths including the top of the screen assembly should be confirmed by the pump contractor

    prior to installation.

  • 6.0 SUMM4R Y AND CONCLUSIONS

    Based on the results of the present groundwater exploration and evaluation program, Kufu provides the

    following conclusions for the Clients consideration.

    The present program has been carried out at the request of the Glenmore-Ellison Improvement

    District to construct a 12-inch production well and to assess safe sustainable yield and water quality at

    a site located near the north end of the Kelowna Airport. Background information for the well

    completion program was provided by a preliminary groundwater investigation involving the

    completion of a six-inch test well during the summer of 1999.

    Based on the results of the exploratory and 12-inch drilling program, the subsurface material

    encountered within the zone of saturation between 40 and 208 feet (12.2 and 63.4 metres) consisted

    predominantly of coarse clean brown sand and gravel, with layers of fine sand containing varying

    amounts of silt. One of the intervals, 175 to 183 feet (53.3 and 55.8 metres) contained streaks of clay.

    Following completion of the l2-inch drilling to the base of the upper aquifer (183 to 210 feet), a

    production well was completed with 25 feet (7.6 metres) of 12-inch (305 mm) telescopic well screen

    set from 185 to 21 1 feet (56.4 to 64.3 metres) below surface as shown in Figure 2. In addition a 2-

    foot riser and “Figure K” packer is attached to the top of the well screens, bringing the top of the

    assembly to 182.7 feet (55.7 metres) below ground level.

    During the pumping test, while pumping at a constant rate of 500 USgpm, the total drawdown

    observed in the new 12-inch production well was 24.60 feet (7.50 metres) after 24 hours. This

    represents only 18 percent of the total available drawdown in the well. It was also noted that the

    drawdown occurred at a steady rate of 0.7 feet (0.21 metres) per log cycle. The total drawdown

    interference noted in the 6-inch observation well, located 42.5 feet (12.95 metres) to the northeast was

    2.46 feet (0.75 metres) at the end of the 24-hour pumping interval.

    ,.

    Based on the test results, a transmissivity determination for the aquifer, using the Theis match curve

    method of analysis, is 3.2 x IO5 USgpd/ft.

    Kaka Groundwater Consulting Ltd. Page 11

  • 0 The new well has a theoretical safe yield of 1770 USgpm. The well screen however is designed to

    transmit 750 USgpm at an entrance velocity of 0.1 feet per second.

    0 A copy of the certificate of analysis for water quality is attached to the Appendices of this report.

    Based on the results, the water quality for all parameters tested meets the “Guidelines for Canadian Drinking Water Quality” with respect to health related parameters. As in the case of the six-inch test

    well (shallow aquifer) the concentration of manganese at 0.057 mg/ exceeds the aesthetic objective of 0.05 mg/L by a very minor amount and the nitrate level is slightly elevated, which we have no

    explanation for.

    Kata Groundwater Consulting Ltd. Page 12

  • 7.0 RECOMMENDAUONS

    The following recommendations regarding the new 12-inch production well are made for the Clients

    consideration.

    0 Kala is recommending that a pump capable of delivery somewhere between 750 and 1100 USgpm be

    installed in the new 12-inch production. If it is decided to go with the higher pumping rates, during

    initial start-up drawdown measurements should be taken in both the production and observation well

    to confirm projected drawdowns and safe well yield.

    0 It is currently recommended that a pump setting for the new well be 175 to 180 feet below the top of

    casing. A11 depths including the top of the screen assembly should be confirmed by the pump

    contractor prior to installation.

    0 In order to aid in pump design and selection, K Q ~ U provides a series of pumping level projections in Table 2 which follows. These projections are all based on continuous pumping for a seven day

    period.

    0 At no time should the new well be backwashed (allowing a sudden surge of water back through the

    drop pipe and pump). This is because of the fine sand component comprising the aquifer and

    consequently it is recommended that a check valve be installed above the pump;

    The aquifer is protected from surface contamination by layers of silty fine sand and silty clay, but we

    do recommend that a well head protection plan be adopted. Owners of land located within the well

    capture zone should be informed, and they should be encouraged to take all measures necessary to

    contain any large volumes of potential contaminants;

    Groundwater Consulting Ltd. Page 13

  • 0 Finally with respect to the new production well, provision should be made to include a water meter

    for measuring production and also allowance should be made for measuring pumping and non-

    pumping water levels in the well. The adjacent 6-inch test well could be used as an observation well

    to monitor water levels in the aquifer, and a water level recorder or data logger could be used for this purpose.
