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.
