Soil samples were taken from the constructed mitigation wetland near Rt. 7, next to Parente's Restaurant.. Percent moisture and grain size were analyzed and the results are presented on the following tables:

Percent Moisture

The % moisture is a measure of the wetness of the soil, and is dependent on the composition of the soil particles (grain size).  Wetlands soils are usually characterized by having a greater proportion of clay particles, and are therefore capable of holding a greater amount of water,

Grain Size Analysis

The grain size analysis reveals whether a the wetland soil is made up of a significant percentage of clay. Clay is essential in wetland soil because it absorbs the moisture and has a high water-holding capacity. The particles are so tiny that water can seep in between them (in the pore space) and be held there. The soil also contains silt and sand particles that cannot hold as much water. This may limit the wetland�s water-retaining capacity, and if the area gets an excessive amount of precipitation, flooding may occur. Conversely, if the soil is too porous, the wetland may dry out and plant species may not be able to survive.  This is an important factor in designing mitigation wetlands, particularly along newly constructed highways.

Soil Profile Photos
During each sampling period, soil samples are evaluated (numbered from 1 to 5).  Photographs of soil samples help to provide a visual record of soils at different sampling periods.
