I am attempting to drain an above ground pool through a homemade biochar filter.

The owner had noticed that he had a sensitivity to something in the sunscreens that people were wearing in his pool. He was not even aware the so-called forever chemicals in them. I suspect he was reacting to the nano particles of zinc and titanium, but the other ingredients are the bigger environmental concern.

I cannot prove that this will be effective. It is the best I could come up with considering the timeline I have.

We are running a submersible pump at a trickle through the hose which is weighed down with a rock at the bottom of the drum. The water is slowly rising through the biochar and will come out a hole about halfway up the drum.

This is the part I have a little more time to figure out. The water will flow into a pond that spills into a swamp. I will be taking steps to further clean up the water and soil in the pond. This will include the use of more biochar and biological mitigation/restoration measures. I will try to open up the canopy to get sunlight on the spillway, build up the height of the spillway, and try to get some kind of grasses and/or sedges to grow in it.

The pool will receive a new liner and be filled with city water. The owner has chosen a saltwater system that will present some design challenges that a magnesium might not. Once a big rain hits, the pool will overflow into the pond again. I am open to your thoughts on how to deal with that salt before it reaches the pond and especially before it reaches the swamp.
