Where Saltwater Intrusion Occurs

Saltwater intrusion is exactly what it sounds like – the movement of salt water into fresh water. This can contaminate drinking water and lead to an array of other consequences. Where is this problem most likely to occur and are you at risk?

Not surprisingly, saltwater intrusion occurs mostly off coastal areas. If you have a home in a marshy area near a coastline and your water comes from the ground, you’re at a much higher risk for saltwater intrusion.

Saltwater, which has a much higher density and mineral content than freshwater, can push its way inland and contaminate the freshwater that lies beneath the ground. Many people use well water, extracting it from the ground. This is the main way saltwater can get into your drinking and bathing water.

The construction of canals and drainage networks has also lead to saltwater intrusion. Your home may not be right on the coast, but if it’s in a coastal area near a canal, you might also be at risk.

What about all the road salt after a rough winter? Although it’s not as common as saltwater intrusion from the ocean, it is possible for road salt to get into your water supply. This could only happen, however, if your water comes from a private well and an abundance of road salt has been used over the last few months.
