How Road Salt Affects Water Quality
Just one teaspoon of salt contains enough chloride to pollute five gallons of water. The chloride from salt is virtually impossible to remove from a waterbody once it is there. This means that our waterways are becoming saltier over time. This is a problem because many aquatic species are very sensitive to salt concentrations (aka salinity) and may not survive in saltier conditions. It's important that we take steps to reduce our salt usage in order to reduce the salt runoff at home that enters our waterways.
Besides home, the State of Ohio Department of Transportation has increased the use of salt brine before a storm in place of traditional road salt. Salt brine is a diluted liquid form of road salt that works faster, saves money, and stays in place compared to road salt.
