This general increase in water levels over <br />the past three years may indicate the development of a spoils aquifer in the area. It may also display some <br />effects of the reclamation activities currently being conducted at the Marr Surface Mine which this well is <br />located approximately 500 (eel south (downgradient) of the pit. Water levels over the past 10 years are <br />presented below. Total depth of the well is 110 feet. <br />1984 Dry 1989 101.50 <br />1985 100.67 1990 103.50 <br />1986 102.04 1991 102.25 <br />1987 102.25 1992 101.94 <br />1988 9'1.25 1993 101.58 <br />Also attached are the four quarterly pond inspections for your tile.
