The Upper Thames River Conservation Authority is urging residents to be mindful for the winter when it comes salt and snow.
Road salt has been a trusted source to keep surfaces safe but the conservation authority says salt which is over applied or improperly stored can have long lasting impacts on waterways and drinking water sources.
Once salt dissolves, it doesn’t disspear, melt-water and runoff carry chloride into nearby streams, rivers and groundwater which can harm aquatic life and affecting the quality of drinking water.
The conservation authority offers tips including;
1. Apply Salt Wisely
- Use the right amount. More salt doesn’t always mean more safety. Once the pavement is covered, additional salt offers little benefit and simply washes away.
- Monitor conditions. Apply salt only when temperatures are appropriate (salt is less effective when temperatures are below -10°C).
- Use calibrated equipment. For larger properties or municipal operations, ensure spreaders are properly calibrated so that salt is distributed evenly and efficiently.
- Sweep up the leftover salt. After snow and ice have melted, sweep up any remaining salt to keep it from entering storm drains.
2. Store Salt Safely
- Keep salt covered and contained. Store it on an impermeable surface and under a roof or weatherproof tarp to prevent it from washing away during rain or snowmelt.
- Maintain good drainage. Ensure storage areas are located away from wells, ditches, and storm drains, and that runoff is directed to vegetated areas for natural filtration.
- Inspect regularly. Check storage piles throughout the winter for tears in covers, pooling water, or exposed salt.
3. Choose Snow Storage Locations Carefully
- Snow piles often contain road salt, sand, and debris. Place them away from wells, ditches, storm drains, and watercourses.
- Have a designated snow storage area. These should be on level ground and ideally with a buffer of vegetation to help filter runoff.
- Plan ahead. Identify and prepare appropriate snow storage areas before major storms hit.
