Abstract

The Northwest Kilohana monitor well, located in the center of the Lihue basin on the northeast slope of Kilohana Volcano, was drilled in 1996 and tested to study the hydrology and geology in an area where no other well information is available. The well was drilled to a depth of 1,004 feet from a ground elevation of about 678 feet above sea level and penetrated mafic lava flows (which may include nepelinite, melilitite, basanite, and alkalic basalt) and alluvium characteristic of the Koloa Volcanics. A relatively thick section of unconsolidated sedimentary and clinker layers were penetrated between 33 and -67 feet elevation. Water levels decreased with depth during drilling from 576 feet above sea level when the hole bottom was at 431 feet elevation to 565 feet elevation when the hole bottom was at -144 feet elevation; 10 days after drilling stopped water levels were measured at 590 feet elevation.

Step-drawdown and 7 -day sustained-rate pumping tests were conducted to test aquifer properties in the vicinity of the well. The maximum draw down measured in the well during 7 days of sustained pumping at an average rate of 313 gallons per minute was 206 feet from an initial waterlevel elevation of 590 feet above sea level. Well loss, analyzed from the step-drawdown data, was estimated to be 56.32 feet. A marked decrease in the draw down at about 3,000 minutes into the sustained-rate test is apparent from the draw down data. Water pumped from the well during the aquifer

tests was noticeably warmer than the surrounding atmospheric temperature of 20.6 degrees Celsius. Water temperature was as high as 34 degrees Celsius at 25 minutes into the sustained-rate test but declined to 27 degrees Celsius after about 7 days of pumping.

INTRODUCTION

The Lihue basin is the center of population, government, and industry for Kauai. Recent popUlation growth in the basin has greatly increased the demand for water in the area. The economic setback caused by Hurricane Iniki in 1993 slowed growth on Kauai and may have kept the water supply from reaching a critical stage; however, an ample water supply is needed for the island's economic recovery. Pre-Iniki studies placed Lihue's supply at the highest priority in Kauai's water plans (Commission on Water Resources Management, 1990).

The Northwest Kilohana monitor well (State well 2-0126-01) is one of six monitor wells drilled in the period from April 1995 to April 1996 by the U.S. Geological Survey (USGS) in cooperation with the County of Kauai Department of Water to study the availability of ground water in the southern Lihue basin (fig. 1). The six monitor wells were sited in areas where no wells had been drilled and no subsurface information was available. Five of the six monitor wells were drilled in the central part of the southern Lihue basin. The sixth well was drilled at the southern edge of the basin. The Northwest Kilohana monitor well is more than 3 mi from the nearest pumping wells and provides data for defining the regional ground-water system of the Lihue basin. The Department of Water considers the northwest Kilo-

hana area as a potential site for future ground-water exploration and development.

The objectives of this study were met by analysis of data collected during and after the drilling operation. These data included (1) the driller's description of the drilling history and the well-construction details, (2) water levels monitored as the well was deepened, (3) a caliper log of the uncased well boring, (4) a description of the geology from rock chips (cuttings) brought to the surface during drilling, and (5) the step-drawdown and 7-day aquifer tests. This report documents the location, drilling history, construction details, geologic log, and aquifer-test results of the Northwest Kilohana monitor well.

Setting

The Northwest Kilohana monitor well (State well 2-0126-01) is located in the Lihue basin, a large depression bounded on the west by the high mountains of central Kauai, on the south by Haupu Ridge, and on the north by the Makaleha Mountains (fig. O. The area has undergone substantial stream erosion, weathering, and faulting followed by rejuvenated, sporadic, scattered volcanism. Two major stratigraphic units are found in the Lihue basin (fig. 2): (1) the Waimea Canyon Basalt of Pliocene and Miocene (?) age which was erupted during the main shield-volcano-building stage of Kauai and forms the bulk of the island, including the mountains surrounding the Lihue basin, and (2) the Koloa Volcanics of Pleistocene and Pliocene age which include the rejuvenated-stage volcanic lava flows and sedimentary units that partly cover and fill the floor of the basin (Hinds, 1930; Stearns, 1946; Macdonald and others, 1960). Both the Waimea Canyon Basalt and the Koloa Volcanics have been given formational rank (Langenheim and Clague, 1987).

Kilohana Volcano, in the center of the southern Lihue basin, is a prominent edifice of the Koloa Volcanics. Macdonald and others (1960) described the Lihue basin as a subsidiary caldera that formed to the east of a central main caldera of the Kauai shield volcano. Steams (1946) described the basin as the result of advanced stream erosion and the coalescing of many amphitheater-headed valleys. Numerous subsequent geologic investigations include a gravity survey (Kivroy, and others, 1965), petrologic and geochemical analyses (Macdonald, 1968; Feigenson, 1984; Clague and Dalrymple, 1988; Maaloe and others, 1992), and

radiometric dating (Clague and Dalrymple, 1988). These studies have advanced the understanding of the geology of Kauai, yet the origin of the Lihue basin remains an enigma.

Ground-water exploration in the Lihue basin has been only moderately successful, owing in part to the basin's complex ground-water hydrology. Most of the ground water in the Lihue basin is developed from wells in the Koloa Volcanics, which cover almost the entire basin floor. The Koloa Volcanics are generally considered to have low to moderate permeabilities (Macdonald and others, 1960), but specific capacities of wells in this unit are highly variable. Water levels during drilling in many of these wells declined with depth in the aquifer, indicating substantial vertical head gradients. At the base of the Koloa Volcanics and resting unconformably on the underlying Waimea Canyon Basalt, are the weathered rocks and sedimentary deposits that formed during the period of erosion between the shield-volcano eruptions and the rejuvenated volcanism. These deposits probably have low permeabilities and may retard the flow of water between the Koloa Volcanics and the Waimea Canyon Basalt.

The Waimea Canyon Basalt in the Lihue basin is represented by the Napali Member, the thick accumulations of thin lava flows that formed on the flank of the Kauai shield volcano. In western Kauai, the Napali Member is extensive and forms the most permeable aquifers on Kauai, but in the Lihue basin, the Napali Member crops out only in the mountains encircling the basin. It is not certain whether any of the wells drilled thus far in the center of the basin have penetrated the Koloa Volcanics into the underlying Napali Member. Therefore, the thickness of the Koloa Volcanics and the hydrologic properties of the underlying N apali Member are unknown.

Location

The Northwest Kilohana monitor well (State well 2-0126-01) is located near the center of the southern half of the Lihue basin among sugarcane fields on the northwest slope of Kilohana Volcano. The site is on the western shoulder of a sugar plantation road, about 3 mi west of the intersection with Maalo Road. The well was assigned the well number 2-0126-01 by the State of Hawaii Commission on Water Resources Management using the State well numbering system (table 1).

The area within a 1 mi radius of the well is covered by a network of artificial and natural surface-water features. The south fork of the Wailua River is within 0.2 mi west of the well. The well is about 6.2 mi inland of the eastern coast of Kauai.

Acknowledgments

The construction, data collection, and testing of the Northwest Kilohana monitor well was made possible with the cooperation and assistance of Mr. Murl Nielsen, Manager and Chief Engineer, and the staff of the County of Kauai Department of Water . We are grateful to Mr. Michael Furukawa for permitting the construction of the well on Amfac/JMB Hawaii, Lihue Plantation land. Drilling, aquifer-test, and elevation information were drawn extensively from the notes of G. Wayne Heick of the U.S. Geological Survey.

DRILLING METHODS AND HISTORY

The well was bored by rotary drilling with a 9-7/8-in. diameter tungsten-carbide bit. Air and foam were injected down through the hollow drill stem and circulated back up the space between the stem and the well boring to remove cuttings from the hole. Greater lifting power was needed as the drilling penetrated deeper below the water table, thus the depth of drilling was limited by the capacity of the air compressor to provide the circulation. Drilling was halted at a total depth of 1,004 ft (bottom is at -326 ft elevation). A caliper tool was lowered down the hole to record the caliper-arm extension, an indication of the variation in hole diameter with depth. At 31 ft elevation a blockage was discovered; casing was installed through the blockage and the well

was completed. The elevation of the brass plate in the concrete pad at the well is 678.44 ft and the elevation of the measuring point is 679.06 ft. Flush-jointed 4-in. (outer diameter) steel casing, with perforations between the water table and the bottom, was installed and gravel was packed in the annular space between the casing and the well boring. Table 2 summarizes the construction history of the well and construction details of the finished well are shown in figure 3.

Water levels decreased as the well was deepened but returned to higher levels as the well recovered from the effects of drilling. The drillers reported a noticeable increase in water being circulated from the hole in the intervals between 446 and 441 ft elevation, 423 and 396 ft elevation, at 366 ft elevation, 353 to 349 ft elevation, 323 to 301 ft elevation, and possibly at -189 ft elevation .

GEOLOGIC LOG

The geologic log of the Northwest Kilohana monitor well was compiled from examination of cuttings brought to the surface by the air and foam circulated through the well bore. Samples were collected at 5-ft depth intervals and air dried before being examined macroscopically. The complete lithologic descriptions appear in appendix 1; the geologic log is shown in figure4.

The Northwest Kilohana monitor well penetrated a 1,004-ft section of mafic lava flows and alluvium (the term "mafic rock" in this report includes nepelinite, melilitite, basanite, and alkalic basalt, all of which are dark, fine-grained, igneous rocks but have specific compositions that are not distinguishable in hand specimen). The uppermost part of the section consists of a 5-ft layer of surface soil and 70 ft of mafic lava flows which are deeply weathered. Below the weathered lava flows is a 190-ft section of vesicular lava flows and clinker underlain by 15 ft of highly weathered mafic rocks. Beneath that is a 385-ft-thick layer of dense aa lava flows and clinker underlain by a l00-ft-thick layer of alluvium. The remaining section consists of 120 ft of aa lava flows and 140 ft of alternating layers of residual soil and partially weathered lava flows.

The caliper log of the Northwest Kilohana monitor well (fig. 4) shows intervals where the hole is larger than the drill-bit diameter. Rock layers that are unconsolidated or thin tend to crumble and cave to produce enlargements in the well boring. In contrast, rocks that

are hard, massive, and thick tend to hold the shape of the boring, and thus give a smoother, unvarying log. Below the surface casing (surface casing shows as the smooth upper 200 ft of the caliper log), the log shows prominent enlargements between 418 and 358 ft elevation that correspond with the clinker and saprolite noted in the drill cuttings between 418 and 353 ft elevation. Between 350 and 28 ft elevation, the caliper log is smoother, indicating the rocks are hard and dense and the wall of the well boring is smooth. This interval corresponds with a thick section of dense mafic lava flows in the geologic log. The small enlargements shown by the caliper log probably correspond to individual clinker zones in the aa lava flows. The caliper log extends down to a depth of only 650 ft because of a blockage below that point. The blockage may have been caused by caving from one or more of the residual soil or alluvial layers in the lower intervals of the hole.

AQUIFER TESTS

Two aquifer tests were performed at the Northwest Kilohana monitor well (State well 2-0126-01); a stepdrawdown test to determine the well efficiency and a

sustained-rate test which can be used to estimate aquifer properties in the vicinity of the well. The aquifer tests were conducted using a 50-horsepower, 6-in. diameter submersible pump with the intake elevation set at 214 ft elevation. Measurements of the depth to water in the pumping well were made using an electric tape. The flow rate was measured using a totalizing flow meter.

The step-drawdown test, conducted on January 23, 1996 consisted of four 60-min steps at average rates of 64,164,219, and 325 gal/min followed by 1,190 min of recovery monitoring (fig. 5 and appendix 2). The elevation of static water level at the start of the test was 590.30 ft. The data were analyzed to estimate the two components of drawdown in the pumped well: (1) the hydraulic head loss in the aquifer, and (2) the hydraulic head losses from water entering the well. Estimates of the aquifer loss and well loss shown in table 3 were obtained using the methods of Hantush and Bierschenk and of Eden and Hazel (in Kruseman and de Ridder, 1994).

Values of drawdown measured in the pumped well during the sustained test were corrected by subtracting the estimated well loss at the measured pumping rate

from the observed drawdown. Well loss at a specific pumping rate is calculated using:

S = CQ2 w '

(1)

where:

Sw = well loss, in feet; C = coefficient of well loss, in minutes squared per

feet raised to the fifth power; and

Q = pumping rate, in feet cubed per minute. For an average pumping rate bf 313 gaVmin (41.84 ft3 fmin), the estimated well loss from equation 1 is 56.32 ft.

The sustained-rate aquifer test was done during January 24-31, 1996 for 10,080 min (about 7 days) at an average rate of 313 gaVmin; recovery was monitored for 10,080 min at the end of the test (appendix 3). The elevation of static water level at the start of the test was 590.30 ft. Flow rates during the test fluctuated between 345 and 292 gaVmin with the higher flow rates occurring in the first 60 min of the test. The maximum drawdown measured in the pumped well was 206.22 ft after 10,080 min into the test. After a correction for well loss, the drawdown in the aquifer was calculated to be 157.62 ft. The pumped water was discharged over a steep valley wall about 300 ft west of the well which lies above the south fork of the Wailua River about 1,000 ft away from the pumping well.

A marked decrease in drawdown at about 3,000 min into the sustained-rate test (fig. 6) is apparent in the plot. The record of pumping rate shows that the measured rate dropped about 8 gaVmin over this time period. This decrease in pumping of 2.7 percent of the total pumping rate is probably not large enough to account for the flatness of the drawdown curve.

Water pumped from the well during the aquifer tests was noticeably warmer than the surrounding atmo-

spheric temperature of 20.6°e. At 60 min into the test, the water temperature was 32.4°C; by the end of the test, the temperature had dropped to 27.0°e. The specific conductance of the pumped water also decreased throughout the sustained-rate test. At 25 min, the specific conductance was 1,044 !lSfcm and near the end of the test at 9,120 min, the specific conductance had declined to 566 !lSfcm.

SUMMARY

The Northwest Kilohana monitor well (State well 2-0126-01) is located near the center of the southern half of the Lihue basin between sugarcane fields on the northwest slope of Kilohana Volcano. The well was constructed during the period from December 4, 1995 to February 7, 1996 to study the hydrology and geology in an area where no other well information is available. The ground elevation at the well is 678.44 feet and the well is 1,004 feet deep (bottom is at -326 feet elevation) and has a boring diameter of 10 inches. Flush-jointed 4-inch (outer diameter) steel casing, with perforations between the water table and the bottom, was installed in the hole.

During drilling, water levels decreased with depth from 576 feet elevation when the hole bottom was at 431 feet elevation to 464 feet elevation when the hole bottom was at -326 feet elevation; measurements of the water level prior to the aquifer tests 11 days after drilling were at 590 feet elevation. The drillers reported a noticeable increase in water being circulated from the hole in the intervals between 446 and 441 feet elevation, 423 and 396 feet elevation, at 366 feet elevation, 353 to 349 feet elevation, 323 to 301 feet elevation, and at -189 feet elevation.

The Northwest Kilohana monitor well penetrated a 1,004-foot section of mafic lava flows and alluvium. A

relatively thick section of unconsolidated sedimentary and clinker layers occurs between 33 and -67 feet elevation. Thinner sections containing sedimentary layers are between -192 and -292 feet elevation. These unconsolidated sections partially caved into the well bore before casing was installed and may have contributed to blockages found during caliper logging of the boring.

Step-drawdown and 7-day sustained-pumping-rate tests were conducted to test aquifer properties. The maximum drawdown measured in the pumped well was 206.22 feet (initial water-level elevation was 590.30 feet) during 7 days of sustained pumping at an average rate of 313 gallons per minute. Well loss, analyzed from the step-drawdown data was estimated to be 56.32 feet for an average pumping rate of 313 gallons per minute.

Water pumped from the well during the aquifer tests was noticeably warmer than the surrounding atmospheric temperature of 20.6°C. Measured water temperature rose as high as 32°e at 60 minutes into the sustained-rate test but declined to 27°e as the test progressed.

Dear Ms. Loui:

t ,

We are actively drilling and testing the first three of seven monitor wells in Lihue, Kauai in accordance with well permits issued by the Water Commission in March of this year. Because the wells are deep and we are testing aquifer properties, progress is slower than anticipated and the 6-month period of the well permits will expire before we are able to begin construction of the remaining four wells. We hereby request extensions of construction permits for monitor wells 5626-01 (Puakukui Springs), 5728-01 (Kauhuula Hill), 5722-01 (Puali), and 0126-01 (N.W. Kilohana). We plan to begin construction of the Puakukui Springs Monitor Well on or about September 30, 1995 If you have any questions, please feel free to call me at 522-8292.

Thank you for your consideration of this request. If you have any questions, please feel free to call me or Scot Izuka at 522-8292.

Dear Ms. Loui:

Please find enclosed three well-construction permits for the upcoming joint U.S. Geological Survey/Kauai County Department of Water exploratory drilling program. These applications, for sites on Lihue Plantation land, are in addition to the three applications sent on March 7, 1995 for sites on Grove Farm land. As you are aware, the wells are exploratory in nature and will be used for aquifer test and monitoring purposes only. the wells will be finished with a 4-inch steel casing.

We plan to begin drilling at the first site on or about April 15, 1995 but the order in which the wells will be drilled has not yet been determined as it will depend on coordination with the land owners. If you have any questions, please feel free to call me at 522-8292.
