SCOTTSBLUFF, Neb. (AP) — A regional agency that protects groundwater intends to install a monitoring well near a newly approved disposal well in western Nebraska for wastewater from oil and natural gas exploration and production.

The North Platte Natural Resources District says the monitor well will be located near the wastewater well site north of Mitchell that was approved Wednesday by the Nebraska Oil and Gas Conservation Commission.

The wastewater project has drawn objections from groups that worry that spills could contaminate the Ogallala aquifer or local groundwater. The production water is considered waste because of its high salt content and industrial chemicals.

The natural resources district’s executive director, John Berge, says the district knows from its work with wellhead protection and other programs that the district needs to keep watch for contaminants.
