What is
Frac Sand Mining?
Frac sand mining is
the extraction of valuable frac sand, a specific type of quartz, that is used
in the process of hydraulic fracturing. To understand the importance of frac
sand and the mining of it one must understand hydraulic fracturing. Hydraulic
fracturing, sometimes referred to as “fracking” is the process of gas and oil
shale extraction from newly reachable depths. By fracturing the Earth’s crust
at large depths openings are created for instruments to extract the shale. Frac
sand, along with a mixture of other solutions such as water and carbon, is used
as the main proppant within the fractures. Therefore, the importance of frac
sand mining stems from the heavy reliance on oil and gas throughout the world.
Frac Sand
Mining in Wisconsin
In
2014, the United States lead the world in frac sand extraction with over 54
million metric tons of frac sand (D. Bleiwas, 2015). Nearly half of this came
from the state of Wisconsin. Located in the central and western part of the
state, Wisconsin contains over 135 active frac sand mines, processing plants,
and transportation railways (Figure 1)(Walters et al., 2015). The process of
frac sand mining takes place on sandstone formations from the Cambrian and
Ordovician periods in the Paleozoic era. Formations from this period located in
Wisconsin include the Jordan, Wonewoc, St. Peter, and the Mt. Simon formations
(WDNR, p. 4). The biggest frac sand producing counties of Wisconsin are Chippewa,
Trempealeau, Jackson, and Monroe. However, frac sand mining reaches as far
north as Burnett county, as far west as Pierce County, and as far west
as Waupaca County. Figure 1 show the dominant presence of frac sand
mining throughout the state of Wisconsin.
Impacts of Frac Sand Mining
There are several
negative consequences that result from frac sand mining operations. According
to the Wisconsin Department of Natural Resources, there are various
environmental impacts that frac sanding can lead to if proper precautions are
not followed. The process of frac sand mining can have harmful effects on air.
Dust from mining and handling of the sand and pollution from the heavy
machinery can decrease the quality of the air. Frac sand mining also impacts
the water resources in the areas near the mining sites. If located near a water
system, the air pollutants can travel and settle in these open sources, runoff
from the site, or pollutants may seep into the underground sources. The vulnerability
of freshwater sources during the mining process can also have a negative effect
on fisheries. Poisoned or polluted water can harm the biological life within
these systems. Warm water runoff could increase water temperatures creating an
unusual habitat for these animals.
This may lead to negative economic impacts
as well due to the large presence fishing has in the state of Wisconsin. Because of frac sand mining, there is concern that there will be a burden
put onto recreational lands. The frac sand mining operation comes with noise,
air quality issues, dust, light during the night, and heavy traffic. Traffic and other transportation impacts are a
large concern for citizens of the area. The heavy loads of trucks for hours out
of the day will lower the service life of the roads and harm the condition. Frac
sand mining operations are often very large and that room comes with loss of
forests and other types land cover. They are also not an appealing site. This
comes with concern about overall unhappiness brought by the dominant frac sand
mining operations.
This blog will be dedicated to the application of GIS
software on frac sand Mining operations in Trempealeau County, Wisconsin. With
GIS, we are able to map locations of sand mine facilities, processing stations,
and other related destinations. Because of the many concerns regarding the impacts
of Frac sand mining, we hope to gain a better understanding of the
relationships between these locations and other features. We also are able to
map routes for transportation and calculate the effects that the hard labor
could have on the roads. With the tools learned in the introductory course and
the new tools in this course we will be able to provide analysis on the factors
regarding the frac sand mining operations.
