This is part of the chloride monitoring for the MTO project to discover if chloride levels from road salting can be reduced by the introduction of DLA in this area near a lake bordered by a highway. The chloride levels have dropped from 14 to 10 mg/l since the introduction of DLA to prewet NaCl. So far, the experiment/project appears successful.
