DMV Winter Salt Week

Join us on January 31st between 10am-1pm to learn how salt affects our health and freshwater ecosystems, what’s being done, and how we can support local efforts. During the event we will hear from regional expert speakers, monitor the local waterways in Gaithersburg, Maryland for road salt pollution, and learn how much salt is needed to keep us safe during the winter while keeping environmental health in mind. Members of the media, government officials, nongovernmental organizations, and members of the public are invited to this event.

Much of the event will take place inside with stream monitoring and parking lot demos taking place outside at 10:45am and 12:15pm. Speakers are scheduled to speak at 10 and 11:30am (see agenda below). Local organizations will have tables with information, and volunteer water monitors, government officials, NGOs, and other stakeholders will be available for interviews and discussion about road salt. If you are a stakeholder, we invite YOU to attend and offer your perspective!

While this event is free, we ask that you please register in advance so that we can notify you in case of cancellation due to inclement weather.

The Impacts of Too Much Salt

Although salt keeps our roads safe during winter, using more salt than needed comes at an expensive price to our waterways, our infrastructure, and our drinking water. Winter salt runs off the roads and becomes a permanent pollutant in our waterways. Only one teaspoon of road salt permanently pollutes five gallons of water.

Data compiled by the Interstate Commission on the Potomac River Basin shows a 10-fold increase in chloride (a chemical released from the breakdown of winter salt) in the Potomac River at Great Falls over the past 80 years.

There are 28 streams in Maryland considered impaired by chloride.

This event is brought to you by the Izaak Walton League of America, Montgomery County Department of Environmental Protection, and the Interstate Commission on the Potomac River Basin.
