Prior to installation of the moisture monitoring equipment <br />at the Forward Landfill Stage 1 A closure area, the existing <br />cover soils were removed down to the base of the 4 -foot thick <br />final cover (top left). A backhoe removed the majority of the <br />soils and manually the holes were cleaned up in preparation for the <br />installation of the Drain Gauge by Decagon Devices (top right). The <br />first step in the installation of the lysimeters was augering <br />of a 6 -inch hole deep enough to accommodate the base of the <br />Drain Gauge which houses the tipping mechanism (bottom). Two <br />Drain Gauges were installed side to side at each location, in case <br />one gauge should fail, the other would be serviceable and also for <br />comparisons of the data. <br />
