Tidbits to form statement - Frac Sand Mining
"Frac sand" is a high-purity quartz sand with very durable and very round grains. ... It is used in the hydraulic fracturing process (known as "fracking") to produce petroleum fluids, such as oil, natural gas and natural gas liquids from rock units that lack adequate pore space for these fluids to flow to a well.
Fracking uses water, chemicals and sand under high pressure to extract oil and natural gas from deposits that previously had been considered impossible to reach. The shape and hardness of western Wisconsin sand is highly coveted because its special characteristics help keep fractures open.
Excessive instream sand-and-gravel mining causes the degradation of rivers. Instream mining lowers the stream bottom, which may lead to bank erosion. ... Sand mining also affects the adjoining groundwater system and the uses that local people make of the river.

Many of the cases involve water pollution — where vast piles of sand, sediment and dirt have washed off properties, often after heavy rains, and contaminated waterways.
