Low-moisture foods (LMFs) have water activity at 25 °C (a w,25°C) <0.85 ( Food and Drug Administration (FDA), 2014a ). Under this condition, most bacteria cannot grow to cause illness, spoilage, or produce toxins ( Association, 2009, Scott, 1957 ). However, the inability of bacteria to reproduce at a low a w,25°C does not mean that they ...The lower velocities beneath the water table means that the depth scale is expanded. In addition, the resolution increases beneath the water table because the wavelength decreases at a lower velocity. The reflection that appears to be the water table on some GPR profiles can come from the top of the capillary fringe above the saturated zone.The water table is the level to which water will rise in a large-diameter pipe (e.g., a well) that goes down into the aquifer and is open to the atmosphere.
