| Value-Added Investigation Techniques for Chemical, Geochemical, and Microbiological Constituents in the Subsurface | |||
| The expense of penetrating the subsurface may be off set by the value of the information gained from investigation borings and monitoring wells. Innovative sampling and analysis techniques are playing increasingly important roles in the elucidation of subsurface conditions related to anthropogenic contamination, remediation, hydrogeology, and water quality. This session will focus on new methods of sample collection and/or analysis that improve the quality, quantity, or types of information gained during subsurface investigations. Topics are anticipated to include emerging applications for passive diffusion sampling for dissolved and gaseous constituents, multilevel monitoring well technologies, sampling and analysis for ground water age dating, stable isotope analysis for evaluation of chemical and biological reactions, microbiological sample collection and analysis, and other innovative techniques that provide an extra value through cost reduction, broader suite of data, or improved data quality. | |||
