Like a floodlight with a bad electrical connection, the issue of silica has been flickering for major attention for the past 2 or 3 years. Although an occupational hazard and known killer since the 1960s, silica is again gaining popularity with the trial lawyers and, as a result, is having somewhat of an impact on the insurance industry.

Toxic crystal and silica dust will be blown through the air and on to the neighboring properties. There are a range of negative environmental impacts from the frac sand mining process including air pollution, water pollution, depletion of aquifers and other hydrological effects, excessive noise, and nighttime light.

Environmental impacts of mining have also been evident in Brazil, with some of the world's worst environmental disasters occurring in recent years. These include the collapse of the Fundão tailings dam of Samarco on November 5, 2015 in Mariana, where 50 million cubic meters of mine waste were released, with major effects on …

Although opponents of mining often cite the potential impacts of sand mining on property values as a reason to restrict or ban mining operations, this Policy Study concludes many mining companies are already addressing these concerns with local officials, who have adequate tools at their disposal to manage the impact of sand …
