Why do we need fracking fluid tracers? The fossil fuel extraction industry and related corporations would say you don’t (need to see who polluted your water),…… they are perfect, they never make mistakes, trust them….
Gist reports “..boron and lithium — which both occur naturally in shale — mix with fracking fluid when it’s injected underground, altering the wastewater’s chemical makeup in ways different from other fossil fuel extraction methods”.
Duke University geochemist, Avner Vengosh, and Dartmouth’s Nathaniel Warner teamed up with French researchers to utilize tracers of boron and lithium that occur naturally in shale formations that unite with frac fluid and have “distinctive isotopic fingerprints that are different from other types of wastewater”.
A PNAS study that found methane six times higher in drinking water wells at homes in closer proximity to drilling used Helium as a tracer. “Helium is an inert noble gas with a radiogenic isotope, 4He, that is a major component of thermogenic natural gas. Similar to hydrocarbon components, the abundance and isotopic composition of helium can help distinguish between potential sources and/or residence times of fluids in the crust, including natural gases (15,16, 33)”
The article went on to say “The abundance and relative proportions of aliphatic hydrocarbons (i.e., propane and ethane) and methane in groundwater are also useful for comparing with production gases”
So there are ways to fingerprint groundwater without ADDING tracers.
Earlier attempts by Texas Senator Davis to add isotope tracers via Senate Bill 772 failed.
The industry itself has long used isotope tracers to see if they reached their “zone”, but inconveniently have NOT use tracers to see if they were causing water contamination.
This article talks more about Senator Davis senate bill and the industry’s use of isotopes and is HIGHLY RECOMMENDED reading…..
