AGGREGATE – Sand, gravel and crushed rock is the number one non-fuel mineral resource in the United States in terms of volume and value. In the United States, there are approximately 10,000 active quarries, which yields millions of tons of aggregate. It is becoming increasingly difficult to mine aggregate due to conflicting land uses, zoning, citizen opposition, inability to obtain permits, and environmental issues. Nevertheless, it is estimated that more aggregate will need to be produced during the next 25 years than has been mined during the previous 100 years.

Virtually everything we build requires aggregate materials, either as an engineered soil base for stability or in the form of concrete or asphalt products. Aggregate is used both in and under our roads, highways, streets, sidewalks, airports, railways, parking lots, sewers, foundations and in the buildings themselves. Other specialty uses include pre-cast concrete products, filtration in septic fields, backfill in underground mines, winter road sanding and armoring 'rip-rap', which prevents erosion on shorelines and water courses. In spite of the enormous technological strides over the last century, there are still no economically viable substitutes for aggregate in the construction industry. Aggregate is a critical resource for the province, as important as water and electricity.

At Newton Consultants we are dedicated to assisting our client in properly documenting all stages of aggregate mine extraction. We will assure that extracting aggregate resources is done with minimal impact to the environmental.

Some environmental impacts from aggregate extraction are engineering-related. The most obvious impacts are the physical and visual changes to the landscape. We at Newton reduce the effects of habitat loss, blasting, noise, dust, erosion, and sedimentation through integrated engineering, geologic and environmental planning.

Newton Consultants recognizes environmental impacts associated with aggregate extraction and utilizes systems analysis and risk analysis techniques. Using these methods aggregate mining can be planned and managed to help account for environmental impact.
