[[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 name="example7">LSRCA. 2018.

[[File:Treatmenttrain TRCA.JPG|thumb|550px|Example of a generalization of utilizing a “Treatment Train Approach” illustrated here. Using [[permeable pavement]] as a source control/lot control on your business/residential property, effluent then flows into conveyance control such as an [[Exfiltration trench/exfiltration system]], used in conjunction with the minor stormwater system as shown above. and then flowing into a stormwater management pond (wet pond) for additional erosion and flood control (TRCA, n.d.
