Virtual Seminar: Methods of Sampling and Analyzing Soil Pore Solution
Methods of Sampling and Analyzing Soil Pore Solution
Sampling solute and contaminant movement through the vadose zone before it reaches the groundwater can be a powerful tool in research and remediation.Methods of quantifying and sampling solute (e.g. nutrient, pesticide, pathogen) movement and concentrations in the vadose zone can be a complex and difficult task. The appropriate method of sampling for a given project depends on the solutes of interest, location in soil profile, and water availability.
The presentation will discuss various methods and tools available for extracting soil pore water solution, continuous or discontinuous extraction, tensiometer controlled suction, proper sample storage, and proper pore water sampler material selection depending on chemical suitability. The presentation will also cover different methods of analyzing the solute, their advantages and disadvantages, and what to look for. Download the lecture slides here.
