Reyes, A.G. 2008 Evaluation of water samples from Northland. Lower Hutt, N.Z.: GNS Science. GNS Science report 2008/15 15 p.
Abstract: Water samples were collected from two household wells in Russell and the Pakaraka cold soda spring on 19-20 December 2007. The objectives of the sampling are to (1) determine if viable low enthalpy geothermal systems exist in Russell amd Pakaraka, (2) suggest ways of harnessing low-grade heat that may exist in these areas and (3) characterise the quality of water from the Russell wells and Pakaraka soda spring.
