[[File:(LSRCA Logo) Atherley Narrows annual chloride concentrations (1971 - 2020).png|thumb|650px|A graph showing increasing average levels of chloride found in Atherley Narrows, (a rural sampling location, between Lake Couchiching and Lake Simcoe), over the past few decades, due in part to increased use of rock salt in parking lots, roadways and commercial and residential properties. From 2005 - 2020 the amount of chloride increase per year has doubled when compared to 1971 - 1986 (1.26 mg/L per yr. vs. 0.63 mg/L per yr.) (LSRCA, 2021). It is estimated that by 2120 the average level of chloride within the the Lake Simcoe watershed will exceed the 120mg/L guideline set by CWQG. (LSRCA, 2018)<ref>LSRCA. 2018.

|Rock salt pretreated with liquid MgCl₂ or CaCl₂ lowers the effective temperature range of salt and reduces losses to wind and scatter.  Low chloride alternatives can also significantly reduce the harmful effects of chloride-based salts.

|Reduces salt release to the environment and lowers corrosion effects on infrastructure. May also lead to improved level of service.
