We’ve got water at Chincoteague National Wildlife Refuge, make no mistake about that.
Water on the ocean side of us…
Water on the marshy inland side of us…
But this water isn’t drinkable—too salty. Thankfully, the humans here put in freshwater impoundments, mainly for the migrating shorebirds, but mammals also make their way to this reliable water.
Recently the humans have gone one step further with water they use at their building. They recycle it. The used water from the building goes in one end of this little marsh.
It travels through the gravel bottom, past the plant roots and microorganisms and what have you in the muck,
and reaches the other end cleaned up.
Mind you, they aren’t drinking it, but do use it again. And again, and again, we assume. It’s hard to tell what goes on in there, but that is how water cycles in the real world, so it’s nice they are taking part in cleaning it up.
