<br />I. <br />I <br />I <br />I <br /> <br />2.2 GROUND WATER SUPPLY <br /> <br />I <br /> <br />Water supply for the Swink water system comes wholly from ground water sources. <br />Swink currently has five water supply wells of varying ages, capacities, and <br />conditions. Pertinent data on each well and pump system as derived from the <br />limited data available is listed below. The wells are located as shown on <br />Plate I and all wells are located in the south half of Section 25, Township <br />23 South, Range 56 West of the 6th Principal Meridian. Two of the wells are <br />deep wells penetrating and deriving their water supply from the 1st and 2nd <br />. Dakota Sand formations. These wells are relatively low capacity wells (25 <br />and 65 gpm respectively) and are used as the potable water supply ("soft" <br />water) for the town. The other three wells are shallow wells, deriving <br />. their water supply from the Arkansas Valley Allivium. These wells are re- <br />latively high capacity wells (475, 175, and 125 gpm respectively) and are used <br />as the non-potable irrigation water supply ("hard" water) for the town. <br /> <br />I <br />I <br /> <br />Water supply for the Swink School District #33 is also derived from ground water <br />sources. The school district has two wells, (one "hard" water well and one <br />"soft" water well) located as shown on Plate I. Pertinent data on the school <br />district wells and pumps as derived from the limited data available is listed <br />below. <br /> <br />I <br />I <br /> <br />Well No.1. Well No. 1 is located in the northwest corner of Block 7 of the <br />original Town of Swink. The well was drilled in February, 1909. The original <br />log on the well is not available, however, a record of the formations en- <br />countered was found. Total depth of the well is 760 feet and penetrates 70 <br />feet of the Second Dakota Sand. It is reported that the casing size is 4 inch <br />diameter and no records were located as to the casing depth. The well is <br />equipped with a 5 Hp submersible pump set at approximately 450 feet depth <br />and produces approximately 25 gal. per minute. The well is not registered <br />with the State Engineer's office, however, the water rights in the quantity <br />of 65 gallons per minute on the well were adjudicated in October 1973. The <br />latest pump replacement reported was in May 1973 when a 25 gpm SUMO pump with <br />450 feet of 2-inch fiberglass column pipe was installed. <br /> <br />I <br /> <br />I <br />I <br />I <br />I <br /> <br />Well No.2. Well No. 2 is located in the northeast corner of Block 2 of the <br />RONILEE Subdivision. The original well was drilled in November 1921. The <br />well has been replaced or redrilled three times over the years. The latest <br />work on the well was completed in August 1975 when the well was deepened to <br />618 feet with 471 feet of new 7-inch casing and 150 feet of 6-inch on thin <br />wall casing was installed. The well is equipped with a 4-inch, 10 Hp, <br />Goulds submersible pump set at 460 feet depth. The well is registered with the <br />State Engineer's office and the water rights in the quantity of 25 gallons <br />per minute were adjudicated in October 1973. It is estimated that the well <br />is currently producing approximately 65 gallons per minute. <br /> <br />I <br />I <br />I <br />I <br />I <br /> <br />Well No.3. Well No. 3 is located in the northwest corner of Block 2 of the <br />POWER'S Subdivision. The well was drilled in November, 1965 and is 50 feet <br />deep. The well is equipped with a 25 Hp vertical turbine pump and produces <br />approximately 475 gallons per minute. The well is registered with the State <br />Engineer's office and the water rights in the quantity of 475 gallons per <br />minute were adjudicated in October 1973. <br /> <br />-11- <br />
