Icy breath cascades across
\nour asphalt arteries,
\nmeandering blockages
\nthat we incinerate with
\nshovelfuls of salted grit;
\ntheir cloying excess
\noverspilling into unkempt
\nreservoirs that sigh with
\nthe weight of our
\nforgetful affliction.<\/p>\n

Saturated bedrock
\npipes polluted poisons
\nto groundwater paths
\nthat return flows laced
\nwith chemical cocktails,
\ncrescendos of chlorides
\nthat leach contaminants
\nlike tin soldiers drowning
\nin a toxic, rising sea.<\/p>\n

Wheels spinning as
\nwe fail to gain traction
\nin the drought
\nthat will consume us
\nall.<\/p>\n

This poem is inspired by recent research<\/a>, which has found that road salts and other human sources are threatening the world’s freshwater supplies.<\/p>\n

Freshwater ecosystems are essential for human societies, because they provide important services such as drinking and irrigation water, food, climate regulation and recreation. Although approximately 70% of Earth is covered by water, only about 2.5% of that is freshwater, and this is rapidly diminishing due to human influences. Although the effects of specific pollutants in freshwaters such as heavy metals or pesticides have received attention, other pollutants have been less studied. For example, although it has been known for a long time that human activities alter the total concentration of major ions (or salinity) and the composition of these ions in freshwater ecosystems, this issue has received relatively little attention. Yet this effect, which is known as \u2018Freshwater Salinization Syndrome\u2019, is an emerging water quality problem across the globe, with increases brought about by human activities such as sewage leaks, land clearing, and the application of road salts during icy weather.<\/p>\n

In this new study, researchers have conducted a comprehensive analysis of the complicated and interconnected effects caused by Freshwater Salinization Syndrome and their impact on human health. By comparing data and reviewing studies from freshwater monitoring stations throughout the world, they found a general increase in chloride concentrations on a global scale, as well as more localised trends such as a 30-year trend of increasing salinity in places like the Passaic River in northern New Jersey and the Potomac River that supplies drinking water to Washington, D.C. In order to mitigate the dramatic impacts that this will have on human health and aquatic life, it is therefore essential for greater awareness to be made of the threat that Freshwater Salinization Syndrome poses, so that we change the ways we think about it, study it, and manage it into the future.<\/p>\n
