Oct. 14, 2014, Westerville, OH – A man well known within the ground water industry for creating standards to improve
work in closed-loop ground-source heat pump technology has been honoured by the NGWA.

The
late Ralph Cadwallader, owner of Loop Tech International and Holly
Water Wells in New Waverly, Texas, has received a 2014 Special
Recognition Award from the National Ground Water Association.

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.
