Salt Watch – Gaithersburg, MD

What is chloride pollution?

Road salt (sodium chloride) keeps us safe on roads and sidewalks, but too much can pose a threat to fish and wildlife as well as human health. Fish and bugs that live in freshwater streams can't survive in extra salty water. Many of us also depend on local streams for drinking water. Water treatment plants are not equipped to filter out the extra salt, so it can end up in your tap water and even corrode your pipes, potentially causing serious health concerns.
