There’s a heavy presence of mirelurk near the shore. As stated in the station's terminal, the Water is highly contaminated, even surpassing what the Rad-X can prevent. In the station itself is a Novice Toolbar, outside is a toolbox containing various items.
To the north, there are three raider corpses. One of them contains an Intervention Letter. Read that and the location for the Suffolk Couny Charter School far to the south will be updated in your map (if you haven't discovered it yet)
The raider corpses with the intervention letter are a random encounter, not specific to this location.
