[[File:Chloride level LSRCA.PNG|thumb|650px|A graph showing increasing average levels of chloride found in Lake Simcoe, and its watershed's rivers, streams and groundwater systems over the past few decades, due in part to increased use of rock salt in parking lots, roadways and commercial and residential properties. 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.

From 2003 - 2018 the amount of chloride increase per year has more than doubled from 2003 - 2008 when compared to 1971 - 1986 (1.2 mg/L per yr. vs. 0.55 mg/L per yr.). 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.
