Detailed Summary

A synthesis of well logs from Grand Marsh and immediate surrounding areas shows the following common stratigraphic sequence: a surficial blanket of fine to medium sand (sometimes interbedded with yellow or brown soil/loam), underlain by discontinuous clay layers (often grey or brown), followed by alternating units of medium and coarse sand and gravel. The coarser zones typically provide the principal aquifer for residential wells (with 10-15 GPM yields frequently noted). At greater depths, particularly in irrigation/commercial wells, a transition to sandstone bedrock is observed. Static water levels in residential wells are typically 18–28 feet below ground surface. High capacity wells are screened much deeper, corresponding with thick coarse sand and gravel or fractured sandstone aquifers. Construction is dominated by rotary or jetted mud circulation methods, with steel casing to the aquifer zone and grout/bentonite cement for sanitary sealing.
