Water Impact
Troubled Waters
The cost of quarrying on local water sources is undeniable. Pollution and depletion of groundwater are commonplace when projects like the Old Hazeldell Quarry move into town.
Just a few miles west on Highway 58, another mining operation had damaging effects on Dexter, Oregon which could shine a light on Oakridge's potential future. The blasting from Parvin Butte Quarry is alleged by local residents to have dried up the water wells depended on for farming and everyday life. Many rock quarries, like the Old Hazeldell Quarry, use ammonium nitrate-fuel oil (ANFO) to break apart large rocks and boulders for processing. This blasting has been observed to wreak havoc on local wildlife and groundwater sources.
A Delicate Balance
- Quarries often operate below the water table, requiring constant dewatering. This pumping can significantly lower water levels in surrounding areas, impacting wells used for drinking water and irrigation. A study by the US Geological Survey found that quarries can reduce nearby well yields by up to 50%. source
- Dust, sediment, and chemicals used in blasting and processing can easily infiltrate water sources, contaminating them with harmful pollutants. This not only affects drinking water quality but also disrupts aquatic life, impacting recreational activities like fishing and harming the ecosystem. source
- Quarries can alter the natural flow of water, affecting streams, rivers, and wetlands. This disrupts downstream ecosystems, impacting fish populations and threatening sensitive habitats. Additionally, heavy machinery and increased truck traffic can damage streambeds and increase erosion, further deteriorating water quality.
Oakridge's future
The potential ramifications for Oakridge are clear. If the Old Hazeldell Quarry is approved, our very lifeblood is at risk.
