We are starting to design a visitor facility for the Fish & Wildlife
Service in Pennsylvania . Site is adjacent to a tidal marsh. Geothermal
seems like a good possibility for the project for a number of reasons
(quiet, less visible equipment, efficiency, etc.)

So why am I skeptical? Our mechanical engineer tells me to think of it as
using the ground water as a giant seasonal storage device...But there is no
such thing as a free lunch, right?

So, 2 questions for the list:

1)what experience have you had with geothermal, and

2) has anyone seen studies regarding the long term effects of geothermal
system on groundwater/aquifer systems, especially near wetland/marsh
