Pardon the Intrusion

Sea Change

Today, we are exploring a growing threat to our freshwater supplies in coastal regions all over the country. With climate change, we are experiencing sea-level rise and more frequent droughts, both of which make it easier for saltwater to creep into places we don’t want it.

First, we go to Plaquemines Parish, an area that’s been dealing with the effects of saltwater intrusion on their drinking water for months. An extreme drought across the Midwest has meant a less-than-mighty Mississippi. Which, has allowed seawater to come up the River—otherwise known as our drinking water supply down here. And then we travel to the coast of North Carolina, where we see another impact of saltwater intruding where we don’t want it. And we find out: what happens to agriculture when the saltwater comes in? Both of these places offer a glimpse into what could become a saltier future for much of our coastal communities.
