Rutland Marsh 

Five dedicated groundwater monitoring wells were drilled at Rutland Marsh near Rutland in Humboldt County. Rutland Marsh 1 is 20 feet deep and is monitoring the water table in the Quaternary till above the bedrock aquifer. The next deepest well (Rutland Marsh 2) is 80 feet deep and allows us to monitor an upper aquifer zone (Gilmore City Formation) in the Mississippian aquifer. Rutland Marsh 3 is 150 feet deep and taps water from the lower portion of the Gilmore City Formation. Rutland Marsh 4 is 200 feet deep and is monitoring the upper portion of the Mississippian Maynes Creek Formation. The deepest well (Rutland Marsh 5) is 280 feet deep and taps water in the lower part of the Maynes Creek Formation.

Core descriptions (quaternary and bedrock)  have been prepared for the well nest site.

Pump tests were performed on all five wells to determine the water level response when the wells were pumped. During the well drilling, isolated intervals were selected for water quality analysis. These intervals were isolated using a packer (an inflatable device) and then water samples were taken.

Water quality analyses were performed on the five completed wells in July 2002 and April 2003 (click here for water quality results). These wells will continue to be sampled to monitor the water quality in these aquifers..
