How does the Edwards aquifer recharge itself? Watch and see!

This is a picture of the above sink hole during dry times.  It is 28" in diameter.  Note the corkscrew, smooth walls.  The sink hole has received water for centuries.  If wastewater is discharged into this creek bed, guess where it is going to rapidly go?  Right.  Right down the sink hole into the Edwards Aquifer.  "Rapid Recharge" it is.  

The Trinity Aquifer recharges far more slowly... perhaps a few 'sink holes' but more 'percolation' of rainwater down the evaporative rock layers that overlie the Trinity Aquifers.  The slow recharge of the Trinity Aquifers reminds of us the fragility of our Hondo Canyon aquifers.  Their slow 'recharge' methods cannot tolerate excessive, rapid  depletion.
