Danger in the Air: Health Concerns for Silica in Outdoor Air Introduction In recent years, the dramatic expansion of hydraulic fracturing and horizontal drilling technology to extract gas and oil, commonly called “fracking,” has led to boom in sand mining across the upper Midwest, creating a significant public health threat in the region.
In the following article, Josh Thomas from instrumentation specialist Ashtead Technology, discusses the risks associated with dust at quarries, and highlights the vital role of monitoring. Almost all quarrying operations have the potential to create dust. Control measures should therefore be
Moreover, adjacent eco-systems are affected by noise, dust, pollution and contaminated water. Pits and quarries disrupt the existing movement of surface water and groundwater; they interrupt natural water recharge and can lead to reduced quantity and quality of drinking water for residents and wildlife near or downstream from a quarry site.
Uncontrolled dust and erosion can cause a multitude of problems for quarry operators. For example, the build-up of dust on site machinery can cause frequent and expensive breakdowns, while dust that exits the site boundary through wind effect or on vehicles can be a
