Saltwater Intrusion, a “Slow Poison” to East Coast Drinking Water

Saltwater Intrusion, a “Slow Poison” to East Coast Drinking Water – Circle of Blue

Saltwater intrusion refers to the landward movement of seawater into freshwater systems. It’s a game of density: saltwater is denser than freshwater, so it remains underneath the freshwater in water tables. When the freshwater volume decreases, saltwater begins to take its place. Mixing then occurs, contaminating the whole supply. At high concentrations of salt in drinking water, people can develop hypertension, which exacerbates pre-existing health conditions and puts the elderly at higher risk of stroke.

EPA Warns of Health Problems When PFAS Levels in Drinking Water Are Inconceivably Tiny – Circle of Blue

For members of the general public who are attuned to drinking water contaminants, the EPA announcement is raising concerns, according to John Lovie, president of the Whidbey Island Water Systems Association. Located in Washington state, the association counts about 100 water systems as members, which range in size from several thousand customers to just three or four. The town of Coupeville, one of the largest in the association, is dealing with PFAS chemicals in its water.
