Salt: Research
On this page:
Research to reduce salt (chloride) in surface and groundwaters is vast. Research on salt-free water softeners, winter maintenance best management practices, the impact of salt on aquatic toxicity, the economic impact of salt on infrastructure, and the interaction of salt and heavy metals are a few of the many study areas. Below are a few of the highlights.
