Although groundwater is the primary source of drinking water in Hawaii, there are no wells extracting groundwater near the summit of Maunakea. The nearest wells are located approximately 12 miles away in Waikii Ranch along the Saddle Road. TMT will install a zero-discharge wastewater system, with all wastewater collected and transported off the mountain for proper treatment and disposal. As such, hydrologists have determined there is no reasonable prospect of adverse impact on groundwater.

For specific information about TMT’s impact on the aquifer, see Judge Amano’s 2017 Report and Recommendations on page 94, item 506.
