The issue of rising chloride (salt) levels, and the related impacts on Ontario’s lakes and rivers is an important topic of concern for FOCA.
Salt is accumulating in the environment and poses an emerging threat both to ecosystems and human health. Once introduced into an ecosystem, salt can become a persistent problem, since there are really no biological processes that will remove it. Reducing the amount of salt entering waterways is an important way to protect our aquatic ecosystems.

The Smart About Salt Council is a not-for-profit organization which offers training to improve winter salting practices and recognizes industry leaders through certification. They provide resources to help ensure that the right de-icing product is used, at the right time and in the right way. Their mission is to protect freshwater from winter salt applied on facilities.
