B4 graph created October 28, 2002

The PVC mat penetration device, Well B4, is located at Station B4 just beyond the Sta. B3 area of neke fern. Mixed wetland plants occur here, mostly para grass

The following legend applies to the graph above:
Vertical lines "I" and "II" mark changes in the water level measurement device: before I - two measurements of water or slurry thickness made at this station in April and June 2002 during augering and penetration device installation; I - first measuring tape device used (2 measurements); II - final tape device with modified weight used thereafter. Blue line is height of water above the "solid" bottom; green line represents "top of mat" calculated from tape reading from solid bottom to pipe lip; brown line represents "bottom of mat" calculated as "top of mat" minus mat thickness. Vertical line representing well is shown at selected point in time, plotted from the measurements solid bottom to pipe lip.
