The U.S. Bureau of Mines drilled five test holes 200 feet <br />south of the proposed tailings impoundment area, and monitored <br />the amount of ground water that flowed into these drill holes. <br />These tests established that the ground water level dropped <br />from 53 feet to 86 feet below the surface during the period <br />between September and December: Since it is situated 30 to 65 <br />feet higher than.the elevation of the U.S. Bureau of Mines' <br />test area, the ground.water level under the White Cloud and <br />Wynona mines, and the proposed millsite and tailings impound- <br />ment area, is somewhat lower than 53 feet below the surface. A <br />similar decline in the ground water level undoubtedly occurs <br />beneath these areas during these same months. <br /> <br />
