C&E,

You lost me. You fear the build up of salt at your leach field but think
that the build up of salt is ok at your drywell. Why is that?

The drywell is not tasked with biologically breaking down waste material
like the septic system is. High salt in the drywell area shouldn't
matter much, while high salt in the septic system could interfere with
the necessary bacteria.
