Citation: Rimon, Y., O. Dahan, R. Nativ, and S. Geyer (2007), Water percolation through the deep vadose zone and groundwater recharge: Preliminary results based on a new vadose zone monitoring The experiment involves the combination of two techniques: the Vadose Zone Monitoring System (VMS) and cross-hole geophysics. The VMS allows continuous measurements of water content at different depths of the vadose zone (Dahan et al., 2009). In addition, it provides the possibility of pore water sampling at different depths.

Note 1: This guide may be used to decommission boreholes where no contamination is observed at a site (see Practice D420 for details); however, the primary use of the guide is to decommission Additional vadose zone monitoring (beyond what is currently described in the QAPP) for model development will not be conducted. The initial Task D model will be developed using Dr. Otis’s previous work in the WSA. After collection of field data, the model will incorporate the WERF project’s STUMOD model specific to Florida soils (i.e., vadose groundwater monitoring wells near the water below the SDA.

Continuous information on leaching and mineral production efficiency enables monitoring for potential leaks from the bottom of lagoons to the subsurface, as well as supervision of earthen dams’ safety. Therefore, monitoring of the vadose zone and appropriate management practices using vadose zone concepts is a prerequisite for understanding and successfully preventing groundwater contamination. Much of the Handbook of Vadose Zone Characterization and Monitoring is devoted to current and emerging techniques for vadose zone measurement and monitoring of chemical and microbial pollutants. The vadose zone, also termed the unsaturated zone, is the part of Earth between the land surface and the top of the phreatic zone, the position at which the groundwater is at atmospheric pressure. Hence, the vadose zone extends from the top of the ground surface to the water table.

A vadose zone monitoring station that was installed in a sand dune area enabled long-term continuous measurement of rainwater percolation across a 20-m-thick vadose zone. Continuous data on the temporal variations in the water content, along with variations in pore water chemical composition, were collected for more than 10 years (since 2003).

Water in the vadose zone has a pressure head less than atmospheric pressure, and is retained by a combination of adhesion, and capillary action. If the vadose zone envelops soil, the water contained strategy for vadose zone monitoring has not been developed. This report addresses the need to identify appropriate technologies and monitoring configurations for a DVZ monitoring strategy applicable to the Hanford Central Plateau. As monitoring development recommendations in this report are implemented, transport in the vadose zone. The field studies were also done to investigate advanced monitoring techniques for evaluating flow-and-transport mechanisms and delineating contaminant plumes in the vadose zone at the Hanford Site. The studies were conducted as part of the Groundwater/Vadose Zone Vadose zone characterization and monitoring are essential for: • Development of a complete and accurate assessment of the inven-tory, distribution, and movement of contaminants in unsaturated-saturated soils and rocks.

Vadose Zone monitoring has occurred for decades, and is still on-going. The Nebraska Vadose database standardizes collection, processing, analysis, and sharing of vadose zone monitoring data, including historic and new information. Currently, our oldest dataset is from the 1980s. We will digitize paper copies of . information available for everyone The vadose zone, also termed the unsaturated zone, is the part of Earth between the land surface and the top of the phreatic zone, the position at which the groundwater is at atmospheric pressure.
