This quarterly newsletter emphasizes full-scale case studies for treatment of problematic contaminant combinations in groundwater, and ISCR's related ability to provide safe, rapid and complete remediation (i.e., without dead-end accumulation of potentially problematic catabolites). It also explores issues surrounding longevity of treatment using EHC®; the original injectable ISCR reagent for groundwater applications, and a trenchant clarification of the latest disinformation campaign propagated by sales agents of simple polylactates.

If it doesn't ring true, there's no way you will make a prospective customer believe it. In marketing, hope conquers nothing...
The famous Italian natural philosopher and mathematician, Galileo Galilei (1564-1642) wrote in his diary that "All truths are easy to understand once they are discovered; the point is to discover them." Oftentimes, in the science of environmental remediation it can be difficult to navigate the best path forward in a noisy environment of competing technological claims...
Lead Consultant, Burns & McDonnell successfully integrates blended potassium permanganate for source area treatment followed by an EHC® PRB for plume control, resulting in significant overall reduction of chlorinated ethene concentrations throughout the groundwater PCL Exceedance zone...
In evaluating the longevity of EHC, several consumption mechanisms of the reactive components need to be considered: 1) ZVI oxidation and carbon fermentation due to consumption of terminal electron acceptors (TEAs), such as dissolved oxygen (DO), nitrate and sulfate; 2) Anaerobic corrosion of ZVI; 3) Organic contaminant reduction; and 4) Trace metal reduction and precipitation...
