Letter From The President - An Appreciation for Professional Skepticism
Circa July 2014, Provectus introduced to our industry the concept of controlling methanogenesis during
in situ remedial actions that employed conventional ERD or ISCR technologies. Since that time, we have effectively integrated our Provect-CH4
® antimethanogenic reagents (AMR) into ERD-CH4
®, Provect-IR
®, Provect-IRM
®, EZVI-CH4™, and AquaGate
®-CH4™ (multiple patents issued/pending) yielding improved (
i.e.,
safer, more efficient, more effective, and less expensive) remedial amendments. And we have successfully applied millions of pounds of these improved products at multiple sites throughout the USA, Europe and Ocean Asia.
Based on previous experience, we knew well that the introduction of an entirely new concept and associated technologies would generate discussion and debate. While critical, most of these interactions were professional, mutually respectful, and productive. Moreover, we knew that as recognized technologists and seasoned practitioners the industry would rightfully expect from us more rigorous documentation of efficacy and proof of performance than it would expect from others who might introduce a new flavor of a cloned technology.
As anticipated, there were three main perspectives on the potential safety and efficacy issues of excessive methane production and its control (see table below)
i.e.,
those who:
i) accepted/acknowledged the issues,
ii) denied/ignored them, and/or
iii) understood and appreciated potential issues, but maintained a position of neutrality
Initially, the "Professional Skeptic" category represented the majority of our colleagues. They generally accepted and acknowledged the importance of excessive methanogenesis but maintained a reserved position until further evidence convinced them that AMR chemistries and our associated remedial products are valid and effective.
In these Newsletters, we try to provide information to help in that transition.
To our readers who became valued clients and gave us the opportunity to demonstrate our technologies, we thank you for your leadership, forethought and confidence in us. These are the efforts that yield critical laboratory and field data that we can share with others to complete the modernization of conventional ERD and ISCR technologies.

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 dominant microbes in reduced environments,
in situ remedial actions employing conventional (
i.e., no active control of Archaea) ERD amendments such as [emulsified] oils/lecithins, lactates/sugars, simple hydrogen release compounds or conventional ISCR reagents such as EHC
®, Ferox-Plus
®, other redox substrates (EHS)
et cetera can generate excessive amounts of methane.
In 2014, the advent of Provectus' antimethanogenic reagents increased industry awareness of potential issues associated with excessive methanogenesis during
in situ remedial actions. Accordingly, two common questions were being asked by seasoned remedial practitioners when they began looking at methane production associated with the use of conventional ERD/ISCR/EHS reagents....and finding it!
Where is this excessive methane coming from?
Did the addition of my remedial amendment induce excessive methane production?

- WHAT'S IN THE BAG? -
Provect-IR
® Antimethanogenic ISCR Reagent
Various analyses have been made between Provect-IR and purportedly similar ISCR reagents. However, a straightforward comparative analysis of Provect-IR Antimethanogenic ISCR Reagent and other older, conventional (
e.g., no active control of excessive methanogenesis) ISCR materials yields a very compelling story (read full report
HERE).

Footnotes:
Calculations based on Provect-IR average ZVI "a" particle size of 17.5 microns.
Calculations based on Other average ZVI "b" particle size of 62.5 microns.
Our standard "Provect-IR15" product line material has 15% (weight basis) ZVI which is of premium grade, optimal particle size to balance reactivity and longevity, and very high in terms of purity and reactive surface area. Of course, customized formulations of Provectus products are always available based on site-specific needs. Comparing Provect-IR to seemingly similar ISCR reagents, it has:
- Natural antimethanogenic compounds
- Multiple hydrophilic, nutrient rich, complex organic carbon sources
- ZVI average particle size ca. 20 micron (varies based on product)
- Chemical oxygen scavengers
- Vitamin and mineral and nutrient sources
- US Patent protection (7,129,388; 7,531,709; 7,828,974; 8,147,694; 9,221,699).
Staff now at Provectus developed some of the original, conventional/older non-antimethanogenic ISCR reagents over 10 years ago so we know best that Provect-IR is simply a safer, better product. And it is very cost competitive!
In the immortal words of the former owner of Remington (Norelco) Razors - Mr. Victor Kermit Kiam II (1926-2001):
