  • Respirable Crystalline Silica from Sand Mining Wisconsin

    Sand Mining in WisconsinWhat Is Respirable Crystalline Silica (RCS)?What Concerns Are Being Raised by Communities Near Newer Sand Mining Operations?What Can Communities Do to Protect Residents’ Health?Sand mining is not a new practice in Wisconsin. The recent demand for high-quality quartz sand for a natural gas drilling process called hydraulic fracturing (also known as “fracking” or “fracing”), however, has greatly increased this activity especially in Western Wisconsin. While Wisconsin has deposits of sand that are used for the hydraulic fracturing process, the drilling occurs in shale deposits containing oil and natural gas that are found in other states, such as Texas, North Dakota.
