Is it wise to collect snow near roads for melting?

Snow Contamination Risks

Collecting snow near roads can expose you to various contaminants, including heavy metals, pesticides, and other pollutants that have accumulated on the road surface. These contaminants can be absorbed into the snow or deposited onto the surface as the snow melts. According to the US EPA, some of the common pollutants found in road runoff include lead, copper, and zinc.

Safe Snow Collection Techniques

If you must collect snow near roads, follow these safety guidelines: stay at least 50 feet away from the road, collect snow that has not been contaminated by de-icing chemicals (typically within 1-2 hours after application), and use a clean container to collect the snow. Consider using a tarp or large bucket to collect and melt the snow, and always prioritize safe handling and storage of the melting water.

Melting Water Safety

When melting snow, ensure that you use a clean and sanitized container to collect the water. A minimum of 1 part bleach to 10 parts water is recommended for sanitizing containers. If melting snow from a road, assume that the water is contaminated and take extra precautions to ensure safe handling and storage. Consider boiling the water before consumption or use, or using a water filter to remove impurities.
