A new study revealed that the breakdown of petroleum underground can release arenic into groundwater

In a long-term field study, U.S. Geological Survey (USGS) and Virginia Tech scientists have found that changes in geochemistry from the natural breakdown of petroleum hydrocarbons underground can promote the chemical release (mobilization) of naturally occurring arsenic into groundwater. This geochemical change can result in potentially significant arsenic groundwater contamination.

Tackling Arsenic With Adsorption

Supai, Ariz., is the capital of the Havasupai Indian Reservation in the western Grand Canyon. The reservation is the site of some of the country’s most beautiful waterfalls and is a popular destination for hikers and backpackers. In fact, hiking is one of the few ways to reach Supai, which is the only place in the U.S. where mail is still delivered by mules. The nearest surfaced road is 9 miles away.

Heavy Paper

The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring an average of 54 cu meters of water per metric ton of finished product. As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water and state-of-the art water treatment.
