The Frontenac ATV Club has started using liquid calcium chloride on local trails in North Frontenac to help control dust—but some residents are raising concerns about the possible impacts on pets, wildlife, and the forest environment.
In a Facebook post, the club warned that the chemical “is a hydroscopic and a deliquescent,” which means it can pull moisture from skin or paws. “It can cause irritation or rash to skin if not washed off,” they wrote, and recommended dog walkers consider using paw booties for the next few days.
That warning led to more questions from community members.
“If it hurts dogs’ paws, what about wildlife that doesn’t have booties?” asked one resident. “And what about birds that eat insects from the trail—could it affect them too?”
What Is Calcium Chloride?
Calcium chloride is a salt-based chemical commonly used to keep dust down on dirt roads and trails. It works by attracting and holding moisture, which keeps dust from rising into the air.
While it’s effective at reducing dust, it can also cause skin dryness, irritation, or chemical burns on contact—especially if not washed off soon. That can be a concern not just for dogs, but also for wild animals that walk the trails.
It can also dry out insects on the trail, which may impact local birds and other animals that feed on them.
Are There Safer Alternatives?
Many other communities use more eco-friendly options that are gentler on people, pets, and nature. Some common alternatives include:
Lignin Sulfonate – A byproduct of wood pulp that helps bind dust without harming plants or animals.
Enzyme-Based Sprays – Natural, biodegradable products that work well on trails and don’t cause irritation.
Magnesium Chloride – Similar to calcium chloride but milder and less damaging to the environment.
Water Trucks – Simply spraying water works temporarily but needs frequent reapplication.
Some towns combine water with natural binders to reduce both cost and chemical use.
Respect for Everyone on the Trails
Dust control is a real issue, especially for people who live near these trails and deal with dust blowing into their homes all summer long.
“We get coated in it—our gardens, windows, everything,” said one homeowner. “I understand why they’re doing it, but I also want it done safely.”
Finding a solution that keeps the trails safe, the dust down, and the environment protected will take input from everyone—riders, hikers, residents, and wildlife lovers alike.
