Service Director Paul Barnett said when it starts to snow, 40 percent of the city will receive the blue salt. 60 percent of the city will receive regular rock salt.
Brunswick is trying to determine if the treated salt is more effective at melting snow and ice than untreated salt.
Cameras at two intersections will take pictures to compare the difference. A camera at Laurel and Pearl Roads will monitor the blue mixture. Another camera at West 130th and Grafton Road will monitor the effectiveness of just rock salt.
