“Reasons and Technology for Controlling Excessive Methanogenesis during Remedial Actions: Case Studies and Remedial Alternatives”At many groundwater remediation sites, excessive production of methane has been observed following the addition of organic hydrogen donors such as (emulsified) oils/lecithin, sugars and conventional ISCR reagents. This is because methanogens are commonly the most ubiquitous indigenous microbes in anoxic aquifer settings. And given that methanogens replicate in 1 to 2 hours (whereas Dehalococcoides spp. for example double in 24 to 48 hours), they often bloom and dominate following the addition of organic hydrogen donors, thereby liberating large amounts of methane gas. There are at least three important consequences of this response: Come learn the consequences of this response in addition to the answers to these questions: What is the problem with Methane? How can we control methanogens? and What are the cost/benefit analyses?
