Here in central Wisconsin we are living the present day “Sand Rush”. I’m not talking about any ordinary sand, but very fine grained silica sand derived from quartz. This sand is being used all across the United States as an aid in a mining process called hydraulic fracking. This is when mining companies pump this fine silica sand under thousands of pounds of pressure deep into the earth to create cracks or open existing fractures in the earth to open once inaccessible deep pockets of natural gas. Much has been said via the local newspapers, online articles, and news stations, but just as much of my knowledge has come from the small town ‘coffee talk’ at the local gas stations by men that work at these very mines. These mines shouldn’t be anything new to the state since we already have at least 60 active sand mines and 32 processing plants (Hubbish), but everyone seems to be blown away by the most recent events. These mines have been popping up in un-zoned areas of WI, and mining companies are rushing to push permits to get the sand out of the ground to cash in when the going is good. This however leaves citizens of the area scratching their heads saying what just happened, is this good or bad for the environment, will this affect me?
Silica sand in its own has been equated to poor man’s gold, since it is easily accessible in this area of Wisconsin and worth a fortune to those who demand it. Prime land containing high silica sand concentrations is selling for $10,000+ per acre, and land that is rail road accessible is selling for thousands more. One must understand that not all proposed mine sights are forested or crop land. Many sand mines are popping up in already established gravel or sand pits, but it seems large scale mines are taking a brunt of the negativity. Near Tunnel City, WI a 500+ acre mine is in place, and it went from a forested/ field atmosphere to now a gigantic excavated area with mountains of white sand piled to the sky and trucks that never seem to stop coming in and out hauling sand to be transported elsewhere. Post mining management plans are in place, that once this area is mined out, the over burden or (top soil) will be placed back on the landscape, and reseeding will be enacted (WIDNR).
I am not picking a side on whether these mines should or shouldn’t be in operation, but I will bring to attention as to the current problems or issues that local residence have with these mines especially the ones in Monroe Co, WI aka Sand Capital of Wisconsin. Concerns with these mines are that it consumes huge amounts of water for its wash plants, and in the case of the Tomah, WI, Unimin (sand mining company) wishes to buy its water usage from Tomah. This equates to millions of gallons of usage. Concerns of the near imaginable water use has many concerned about draining the aquifer and the consequences as a result. Cranberry growers who rely on its water supply for harvest every fall are asking questions as well. To mention a few more concerns come from the broad spectrum are what about the actual water quality and drainage impacts on the area, or the air pollution and nuisance of the fine sand dust. Then there is the thought of the sound and light pollution that goes along with any operation. Whether it is the loud machinery digging the sand, dump trucks constantly hauling sand on highways, or the increase railroad traffic has people on edge.
Most recently however, the mine in Tunnel City has come under attack from the state and Federal Government as the mine now has a direct impact on the federally protected karner blue butterfly. This butterfly has been protected since 1992, and its territory is primarily here in WI, on the very sand areas that these mines are buying up (Golden). These butterflies are in this area because of the wild lupine that thrives in the central sandier region of the state. However, actions have already been taken and land has been fenced off and set aside to help preserve karner blue habitat. The WI DNR is over viewing this process as stated in the La Crosse Tribunes article “A Threat to Sand Mining.”
We have just barely scratched the surface of the booming business of sand mining here on Wisconsin soil. I do know one thing for certain, that these sand mines are here and here to stay regardless of public opinion. So the public’s approach isn’t to stop these mines, but what can be done is to slow the process of mining permits and look more deeply at the environmental impacts.
