Hydrogeologic Guidelines for Large Scale Geothermal Heat Pump Systems

Lack of adequate hydrogeologic investigation is presenting major
challenges for some recent large scale (non-single family housing)
geothermal heat pump systems and surrounding groundwater.
In response, the National Ground Water Association is developing
guidance to help the HVAC system designer understand and use
hydrogeologic information to prepare project specifications and
achieve optimal system performance.
The National Ground Water Association has long been an advocate
for the sound application of ground source heat pump technology
and has developed guidelines for the proper construction of closed
loop heat pump systems, as well as advocated to Congress on behalf
of more widespread national utilization of the technology.
The Association recently compiled a database of state regulatory
oversight of GSHP installations.
