An aquifer is an area underground where rainwater is held, usually
between the spaces of sand and gravel. Long Island has 3 major
aquifers. |

|
Glacial Aquifer |
The top of this aquifer is our water table. You are looking at it when
you see ponds or streams. |
|
Magothy Aquifer |
This aquifer is where most of us get our drinking water. It's the
biggest aquifer we have under Long Island. |
|
Lloyd Aquifer |
This is our deepest aquifer and it contains the oldest and cleanest water. It takes a long, long time for water to get down there and that water trickles down only from a few places near the middle of Long Island. |
