Sidewalk salt threatens drinking water: ecologists warn of danger.

Winter preparations and environmental risks

According to ТСН: During traditional winter preparations, sidewalk salt is actively used. However, ecologists warn of the negative consequences of its excessive use: it harms the environment, deteriorates the quality of drinking water, and can pose a threat to human health.

Experts note that after the snow melts, salt enters bodies of water and groundwater, from which it is practically impossible to remove. Studies have shown that the chloride levels in water bodies have tripled over the past 40 years, and over 60% of private wells near state roads exceed the recommended sodium levels.

In some regions, the water has become so salty that it causes corrosion of pipes and household appliances, making it unsuitable for consumption and even for irrigation. Brendan Wiltse, president of the association, emphasized that this is particularly dangerous for houses with old lead plumbing, as aggressive water can leach lead, increasing toxic risks.

Impact on the ecosystem

Salinization has a negative impact on local ecosystems, particularly on zooplankton, an important component of the aquatic food chain. The New York Department of Environmental Protection warns that if this trend continues, some watersheds may reach dangerous levels of pollution by 2108.

Reducing harm

To reduce harm, municipalities are implementing new technologies for economical road salting and pre-treatment methods with brine. This helps reduce the amount of salt used without losing effectiveness. For example, in the Mirror Lake area, a noticeable decrease in salt concentration has already been observed.

Ecologists urge residents and businesses to follow a simple rule: one cup of salt (about 350 g) is enough for a 6-meter driveway or 10 square meters of sidewalk. It is recommended to apply salt evenly only after snow has been cleared.

Usually, regular rock salt is sufficient for dealing with icy conditions. There are also products based on calcium and magnesium chlorides available, but they should be used sparingly.

Sometimes sand or cat litter is used as alternative means against slipping, although they can easily be brought indoors. Also emerging are 'exotic' alternatives such as beet juice, cucumber or cheese brine, as well as brewery waste. However, Wiltse warns that these substances contain a lot of sugar, which stimulates the reproduction of bacteria in water bodies that can cause fish kills.

Principle of moderation

Ecologists urge the cautious and moderate use of anti-ice measures, as this is important for ensuring the safety of people and preserving the environment in winter.

Therefore, while winter preparations and ensuring road safety are necessary, it is important to be mindful of the environmental consequences of using sidewalk salt. By taking sensible measures and alternatives, we can minimize the harm to the environment and public health, ensuring safe conditions during the winter period.
