Cadwallader,
who passed away on July 11, received the award for his
involvement in Texas educating others and creating standards aimed at improving
work in closed-loop ground-source heat pump technology, said an association news release. The award will
be presented in December at the 2014 NGWA Groundwater Expo and Annual
Meeting in Las Vegas.

A
pioneer in the closed-loop ground-source heat pump industry,
Cadwallader also was a leader and proponent for ground water protection
by the contractor working in the closed-loop business. He developed
purging standards that provide for the removal of debris from a
closed-loop system to lower the need for additives to the circulating
fluid to combat biological growth.

He
constructed major closed-loop wellfields in more than 20 of the
continental United States and was an advocate of providing the consumer
with the best product for a competitive price that suits the site
application.

Cadwallader
was a past president of the Texas Ground Water Association, an NGWA
member and a board member on the Geothermal Consortium.
