The Bladon Lysimeter: An Innovative Environmental Characterization Technology

Chemical analysis of groundwater samples is the baseline method of characterizing and monitoring groundwater contamination in the vadose (unsaturated) zone at most waste sites. Contamination moving from the surface to the water table passes through an unsaturated zone that can range in thickness from a few inches to hundreds of feet at a give site. Lysimeters are samplers that are designed to apply suction to the subsurface and are typically used to collect groundwater in the unsaturated zone
