Just one teaspoon of salt in five gallons of water creates a concentration toxic to some aquatic life and increases the corrosivness of water.
Road salts and most deicers contain chloride. When the snow and ice melt, the salty runoff flows down the storm drains to the North Platte River. Chloride is virtually impossible to remove from a waterbody.
Avoid chloride pollution with these tips:
– Shovel early and often to prevent snow compaction and ice formation.
– Scrape ice with an ice scraper or ice chisel.
– Salt or de-ice as a last resort. Salt or de-ice ONLY if pavement temperature is warm enough for application to be effective. Otherwise, lightly sprinkle sand for traction.
– Sweep residue after the melt to prevent residual salt, de-icer, or sand from washing into storm drains.
