Silica Sand Mining and Health. The recent expansion of silica sand mining in Minnesota is raising concerns about possible health risks. MDH is working to develop public health responses and tools to support citizens and communities as they consider these impacts.
Lessons learned from ambient air monitoring related to silica sand mining, processing and transport. Ambient monitoring for respirable crystalline silica on the fenceline of mines and processing facilities did not find air concentrations above the inhalation health benchmark for respirable crystalline silica.
