“…The transmissivity of a buried sand and gravel aquifer, estimated from an aquifer test west of Nett Lake Community ( fig. 1), was about 800 ft2/d (Norvitch, 1963). These estimated transmissivities are in the low part of the range (1,000 to 16,000 ft2/d) reported for other buried sand and gravel aquifers in western Minnesota (Delin, 1986).…”

“…Information about the ground-water resources of the Reservation is available from a report by Norvitch (1963) that describes the geologic setting and hydrogeologic characteristics of the aquifers and the quality of the ground water. Information about the hydrologic balance of Nett Lake is available from an engineering study of water-level control of Nett Lake (TKDA and Associates, Incorporated, written communication, 1988).…”

“…The buried sand and gravel aquifers are water-supply sources near Nett Lake Community. The report by Norvitch (1963) and results of test drilling for watersupply wells indicate that the buried sand and gravel aquifers are small and discontinuous. The productivity of the bedrock aquifers is limited by the density of fractures.…”

“…The productivity of the bedrock aquifers is limited by the density of fractures. Exposed surfaces of bedrock in the northeast part of the Reservation are not fractured (Norvitch, 1963).…”

The geologic and hydrologic terms pertinent to this report are defined as follows: Alkalinity: Capacity for neutralizing acid and commonly reported as an equivalent amount of calcium carbonate. This property is attributed mostly to bicarbonate if the pH of the water is less than 9.5. Aquifer: Geologic or stratigraphic unit that contains sufficient saturated, permeable material to yield usable quantities of water to wells or springs. Confined aquifer: An aquifer for which the saturated zone is bounded by confining beds such as clay layers; also referred to as a buried aquifer. Water levels in tightly cased wells completed in this type of aquifer rise above the top of the aquifer. Conglomerate: Coarse grained, sedimentary rock derived from fragments of other rock. Crystalline bedrock: Igneous or metamorphic bedrock, as opposed to sedimentary bedrock. Discharge: The volume of water that passes a through a given cross-sectional area at a fixed point within a given period of time. Dissolved solids: Total amount of mineral constituents dissolved in water. Granite: Very hard igneous rock composed primarily of quartz and feldspar.
