ISCO and/or ISCR – How to Decide in 2017?
ISCO AND/OR ISCR – HOW TO DECIDE IN 2017? This presentation is an update of the paper by Mueller and Brown (2008). The objectives are to: i) review general and advanced examples of in situ chemical oxidation (ISCO), in situ chemical reduction (ISCR), and related technologies, then ii) summarize initial screening criteria and guidelines to […]
Potential Consequences of Excessive Methane Production Following ERD and Conventional ISCR Treatment: Case Studies and Remedial Alternatives
Potential Consequences of Excessive Methane Production Following ERD and Conventional ISCR Treatment: Case Studies and Remedial Alternatives MSECA – October 21-22, 2016 At some 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 […]

Where Is All This Methane Coming From?
Stable-carbon (δ13C) and naturally occurring radiocarbon (14C) analyses can conclusively identify methane sources in soil gasses, groundwater, vadose soils and ambient/indoor air. Methane in ecosystems can originate thermogenically from regions of petroleum formation deep within the earth and/or via microbial fermentation of organic carbon and microbial reduction of carbon dioxide. Because methanogens/Archaea are often the […]
