The assets sold relate to treating and recycling of flow back and produced water from wells drilled in shale formations.

Under the agreement, Waste Management will acquire Bosque’s water treatment, recycling processes and operations in the Marcellus Shale region, including the states of Pennsylvania and West Virginia.

Waste Management will also acquire mobile water treatment units, frac tanks and joint ownership of certain technology.

The Pennsylvania/West Virginia Market Area vice president James Fish said Waste Management has an unmatched network of landfills and transportation assets overlaying the Marcellus Shale formation.

"With this acquisition, Waste Management is uniquely positioned to provide producers an integrated portfolio of solutions for both drilling solids and waters," Fish said.

Bosque said the company has developed a portable water treatment system for application in oil and gas extraction operations.
