The Effects Of Heterogeneity & Delivery Methods On Remediation

To begin his presentation, Rick discussed the current trends in groundwater remediation. Over the past decade, in situ methods have greatly increased in popularity. Although the use of these approaches is growing, Rick pointed out some limitations. Geological heterogeneity is a limitation to determining hydrogeological aspects of a contaminated site, and how a reagent will… Continue Reading »

Working To Quantify And Overcome Uncertainty

 The theme of this year’s Symposium was “Enhanced Monitoring and Remedial Methods for Contaminated Groundwater”. It became clear that enhancing monitoring and remedial approaches involves recognizing “uncertainty” as a factor in all contaminated site assessments. It was put forth that heterogeneity in the subsurface affects the level of uncertainty in any groundwater study – when… Continue Reading »
