| Goal | Best Choice |
|---|---|
| Cheapest | Sodium chloride (rock salt) |
| Works in extreme cold | Calcium chloride |
| Better for concrete | Magnesium chloride |
| Better for plants/environment | CMA |
| Lowest overall environmental impact | Use less salt, shovel first, apply only where needed |
During winter, ice melt products are widely used to improve safety on sidewalks, driveways, and roads. These materials help reduce slips and falls, but they do not disappear after application.
When snow and ice melt, water carries residual salt and chemicals into storm drains—and from there, directly into local waterways.
Where Ice Melt Goes
Stormwater systems are designed to move water away from streets and neighborhoods, not to treat it.
As snow melts, runoff can carry:
-
- Road salt and deicing chemicals
- Sediment and debris
- Pet waste and other surface pollutants
This mixture flows through storm drains and ditches and is discharged into streams, lakes, and rivers with little or no treatment.
Why Salt Matters
Most ice melt products contain chloride-based salts such as:
-
- Sodium chloride (rock salt)
- Calcium chloride
- Magnesium chloride
Once in the environment, these compounds can:
-
- Increase chloride levels in surface water
- Stress or harm aquatic life at elevated concentrations
- Affect roadside soils and vegetation
- Accumulate over time through repeated winter applications
Even when individual applications are small, seasonal repetition across thousands of properties and miles of roadway creates a cumulative impact.
Check the Temp
Traditional rock salt will not work when temperatures drop below 15*F
Reducing Ice Melt Impact
Winter safety and water quality protection can happen at the same time.
Shovel First
Removing snow early reduces the need for chemical deicers.
Use Less, Not More
Apply only the amount needed for conditions. Excess product does not improve performance.
Time Applications When Possible
Apply before light snow events when conditions allow, rather than after ice has formed.
Sweep After Melting
Remove excess material from hard surfaces once conditions improve.
One Coffee Mug
A 12-ounce coffee mug of ice melt holds enough product for 20 feet of driveway or 10 sidewalk squares.
Use Alternatives When Appropriate
Consider traction or lower-impact options such as:
-
- Sand or grit (for traction)
- Calcium magnesium acetate (CMA)
- Other lower-chloride or plant-based products (where suitable)
Each product has tradeoffs, but reduced overall use is one of the most effective strategies.
- Rock Salt
- Calcium Chloride
- Potassium Chloride
- Magnesium Chloride
- Calcium Magnesium Acetate
- Potassium Acetate
- Beet Juice
- Urea
What it is: The traditional, cheapest ice melt.
Works to: About 15°F (-9°C).
Benefits
-
- Lowest cost
- Widely available
- Effective for typical winter conditions
- Good for large-scale applications where budget matters
Drawbacks
-
- Most damaging to vegetation and waterways
- Corrosive to concrete, vehicles and metal
What it is: The “premium” ice melt.
Works to: About -25°F (-32°C).
Benefits
- Fastest acting
- Generates heat as it dissolves
- Effective in extremely cold temperatures
- Requires less product by weight than rock salt
Drawbacks
- More expensive
- Still damaging to waterways
- Can still damage plants and soil
- Can irritate pet paws and skin
What it is: Sometimes marketed as plant-friendly or pet-friendly.
Works to: About 25°F (-4°C).
Benefits
- Less damaging than rock salt to some plants
- Generally gentler on concrete, metal, and vehicles
Drawbacks
- Slow acting
- More expensive than rock salt
- Doesn’t work well in colder weather
- Not particularly useful in Nebraska cold snaps
What it is: Marketed as a gentler alternative.
Works to: Roughly 0°F to 5°F depending on formulation.
Benefits
- Less corrosive than rock salt
- Generally easier on vegetation
- Often marketed as pet-friendly
- Gentler on concrete than rock salt
Drawbacks
- More expensive
- Still a chloride salt
- Still damaging to waterways
- Not as effective as calcium chloride in extreme cold
What it is: Made from limestone and acetic acid (think vinegar).
Works to: Around 15°F–20°F.
Benefits
- Very low corrosion
- Easier on the environment than chloride salts
- Safer around plants
- One of the safest products for concrete
Drawbacks
- Expensive
- Slower melting
- Less effective in very cold weather
What it is: A high-performance acetate deicer.
Works to: Below -30°F.
Benefits
- Extremely effective at low temperatures
- Low corrosion
- Minimal chloride pollution
Drawbacks
- Very expensive
- Usually used for airports and specialized applications
What it is: Beet juice, molasses derivatives, corn products, and similar additives mixed with brines.
Benefits
- Helps salt stick to pavement
- Can reduce total salt application
- Extends performance at lower temperatures
Drawbacks
- Usually not used alone
- Still relies on salt chemistry
- Can be harmful to waterways in large quanitites
The benefit isn’t that beet juice melts ice. The benefit is that it helps you use less chloride.
What it is: Nitrogen fertilizer used as a deicer.
Works to: Around 10–20°F depending on conditions.
Benefits
- No chloride
- Less corrosive
- Can be safer around concrete
Drawbacks
- Weak ice melting performance
- Adds nitrogen to runoff
- Can contribute to nutrient pollution
Winter Pollution Is Still Stormwater Pollution
Cold weather does not stop stormwater movement.
As snow melts, it continues to transport:
-
- Salt and chemicals
- Nutrients and bacteria
- Sediment and debris
This runoff ultimately enters the same waterways that receive stormwater year-round, including local streams and the Platte River system.

Small Actions, Large Scale Impact
Ice melt use is a community-scale issue.
One property contributes a small amount.
Thousands of properties applying products repeatedly throughout winter creates a measurable load in local waterways.
Stormwater quality reflects these combined choices.
Why It Matters
Ice melt helps keep winter surfaces safe, but it also contributes to chloride levels in local water systems when overused.
By using deicing products more intentionally, residents help:
-
- Protect aquatic ecosystems
- Reduce long-term salt accumulation
- Support healthier soil and vegetation
- Maintain water quality in local rivers and lakes
Winter safety and water protection work best when they are balanced.
