The Maine Department of Transportation (DOT) has a fleet of roughly 400 plow trucks that are used to control snow and ice on app

roximately 8300 lane miles of Maine’s state roads. They usually plan on an average of about 30 treatable events in a winter. This includes the use of rock salt, salt brine and winter sand, a mix of sand and salt. Salt brine is used on roads and bridges prior to a storm to delay ice and snow from sticking to the roadway and is also used in plowing to fight the buildup of ice and snow throughout the storm. Rock salt helps keep roads safe when winter storms hit, reducing winter road accidents, but it can also have negative effects on plant life and aquatic ecosystems. What are the environmental effects of salting that must be mitigated? Select ALL that apply.A) Salt kills roadside plants. B) Salt builds up in roadside soil , changing its pH, preventing the growth of plants. C) Salt corrodes metals like automobile brake linings, frames, and bumpers, and can cause cosmetic corrosion. D) Elk, moose and sheep eat road salt causing "salt toxicosis" where they lose their fear of vehicles and humans, causing many fatal encounters. E) Salt doesn't evaporate, or otherwise get removed once applied, so it remains a persistent risk to aquatic ecosystems due to runoff or ground
