				  "Geothermal Aqueous Closed-Loop Wells" means wells that house a subsurface
				  system of closed-loop pipe that circulates potable water only or a mixture of
				  potable water and performance-enhancing additives such as antifreeze, corrosion
				  inhibitors, or scale inhibitors for heating and cooling purposes. Only

				  Health determines not to adversely affect human health in compliance with
				  G.S.

				  and subsurface construction details of the system;
(7) the heating and cooling system
				  installation contractor's name and certification number, address, email address
