Used in winter to melt ice from roads, salt seeps deep into groundwater until it reaches surface waters. A University of Delaware study illustrates some of the dynamics that affect the phenomenon<\/h2>\n

Salt has always been used on roads to help ice<\/strong> melt<\/strong> during winter periods. This widespread practice, however, could impact groundwater not only during the cold months, according to a study<\/a> from the University of Delaware. The investigation, led by Rachel McQuiggan<\/strong>, a researcher with the Delaware Geological Survey, an agency associated with the same university, was based on monitoring groundwater in a infiltration basin. That is, one of those large basins placed on the side of the road that allows rainwater to be collected.<\/p>\n

The basic idea, McQuiggan explains<\/a>, is to protect surface water from salt<\/strong> seepage. The basins are designed accordingly “with the idea that stormwater benefits from a natural \u2018filtering\u2019 of contaminants as it infiltrates through soil, and contaminants dilute as that recharge mixes with existing groundwater.” But this operation, in any case, does not come without impact.<\/p>\n
