ND study aimed at reducing road dust

A former state Health Department official is leading a research project to determine what works best for controlling dust on gravel roads in western North Dakota’s booming oil patch.

Francis Schwindt is testing eight products ranging from a tree sap product to the magnesium chloride that is commonly used now. The former head of the Health Department’s Environmental Health Section tells The Bismarck Tribune that he might also test crude oil itself.

The eight products were applied to roads in Dunn and McKenzie counties in mid-May. Schwindt says the roads are heavily used by semitrailers and should be good guinea pigs for testing which of the products holds up best and is most cost-effective. Results won’t be known for weeks.
