I'm renting and don't want to have to pay my landlord for an expensive countertop replacement, so I'd like to know how this can be fixed. Also, there is some potential replacement material hidden beside the stove and fridge. [EDIT: When I first posted this, I called it "laminate". Then considered maybe "Contact paper" aka "Peel and stick" countertop. I think the final determination is this is possibly just paint, see end of post.]
Here's the damaged areas, under the switch and the outlet. (Note, dishwasher is seen at bottom of image. Might be a factor.)
Close up of switch damage.
You can see that the laminate/plastic has bubbled away from the substrate. This runs to the left and right of the cracks.
The outlet damage is similar. Water might have got in both places from the top, as it is exposed over both switch and outlet.
Theory #2, as indicated in an answer below, this might be considered a design flaw (not our fault!), and the thin material might be getting warped due to steam/humidity. A good theory, since the dishwasher is just below it. You can see the upper-right corner of the dishwasher at the bottom of this first image.
EDIT: I think it's just paint? The same pattern is on the outlet

Final Update: So the maintenance man comes in, says no that's not water damage, it's just really cheap spray on, they all do that. Then pulled out his silicone caulk, laid down a bead, and wiped it with his finger.
